Types of Garden Rooms: 6 Configurations Explained by a Manufacturer

Quick Answer: There are 6 main types of garden rooms based on configuration: Compact (8-12m², basic double glazing), Standard (15-25m², enhanced double glazing, U-value <=0.30), Luxury (25-50m², triple glazing, U-value <=0.20), Modular (10-30m², relocatable units), Insulated (15-35m², year-round thermal performance), and All-Glass (12-30m², tempered glass panels). All use 6063-T5 aluminium frames. Installation: 1-5 days.

Having spent over a decade in the aluminum alloy sunroom and garden room industry, the Deslano team has gained a key insight: the time customers waste during the selection phase is rarely due to a lack of options, but rather to the wrong method of categorization. Most articles on the market classify these structures by intended use—such as home offices, gyms, or dining areas—yet for someone actually making a purchasing decision, this type of classification offers little practical guidance.

The reason is simple: deciding how to use your garden room is a matter of your own business judgment; however, whether the structure can actually fulfill that purpose depends on its technical specifications—such as floor area, thermal insulation performance, frame strength, and installation speed. These are the factors you need to understand first.

Therefore, this article focuses exclusively on specifications rather than intended uses. Drawing on Deslano’s actual product lineup, we have categorized garden rooms into six main types based on specifications, outlining the core parameters, ideal use cases, and selection recommendations for each. After reading this, you should be able to quickly narrow down your choices and identify the two or three configurations that best suit your needs.

Why Garden Room Configuration Matters for Commercial Projects

When you are procuring garden rooms for a commercial project, the configuration you choose directly affects three things: operational comfort, energy costs, and project timeline. A wrong configuration does not just mean minor inconvenience; it can lead to excessive heating bills, uncomfortable indoor temperatures, or delays in your opening schedule. That is why understanding the structural and thermal differences between configurations matters far more than picking a label like 'office type' or 'gym type'.

We encountered a classic case involving a hotel chain: when purchasing their first batch of "garden rooms," the brand selected the "Standard" configuration—essentially an office-style spec. However, at their Scottish location, the indoor temperature dropped to just 8°C in winter, rendering the units unusable. The issue was only resolved by switching to the "Insulated" configuration—but this process ended up costing nearly 30% more than the original budget.

This lesson teaches us that the first step in selecting a configuration isn't asking "what is the intended use?" but rather "where is the project located, when will it be used, and for how long?" Climate conditions, the operating season, and frequency of use—these three factors determine the required level of thermal insulation and structural strength, thereby narrowing down the appropriate configuration options. That is why we always advise clients to determine the configuration specifications first and consider the intended use second. With the right configuration, any use case is achievable; with the wrong one, even the best intended use is futile.

Configuration vs. Use-Case: A Different Way to Classify

If you search online for "types of garden rooms," the results are typically categorized by function—such as offices, gyms, studios, or guest rooms. While this approach works well for individual consumers, it falls short for B2B procurement. Consider a hotel that needs five garden rooms: two to expand its dining area, two for guest accommodation, and one for a meeting room. Under a function-based classification, you would have to read five separate articles; with a configuration-based system, however, you simply need to understand the specifications of six standard types and then select the combination that meets your specific needs.

This is the logic behind Deslano’s classification system: categorizing products by their structural characteristics rather than their intended use. The advantages of this approach include:

Standardized specifications: Each configuration comes with clearly defined parameters regarding floor area, glazing types, and thermal insulation ratings.

More efficient selection: You can evaluate technical specifications first, then consider suitability for the intended use.

Precise communication: Specifying a "Standard" configuration is far clearer to the manufacturer than asking for a "medium-sized office."

Configuration 1: Compact Garden Rooms (8-12m²)

Compact is where commercial garden room projects usually start. At 8 to 12 square metres, this configuration is designed for businesses that need functional extra space without committing to a large footprint or a heavy investment. Think of it as the try-before-you-scale option: fast to install, quick to deliver, and low enough in cost that you can test the concept before rolling out larger units across multiple sites.

The "Compact" configuration is one of the highest-volume models shipped from the Deslano factory. Many chain brand clients place their initial order for the Compact model—testing the concept at one or two locations before rolling it out more widely.

Key Specifications:

Area: 8–12 m²

Frame Material: 6063-T5 aluminum alloy (standard wall thickness)

Glass Configuration: Double-glazed tempered insulating glass (5mm + 12A + 5mm)

U-Value: ≤0.35 W/m²K

Installation Time: 1–2 days

Production Lead Time: Approx. 4 weeks

Suitable Commercial Applications:

Hotels: Reception extensions or luggage storage rooms

Restaurants: Private dining rooms for 2–4 people

Nursing Homes: Nurse stations or small activity rooms

Schools: Reception areas or small tutoring rooms

Selection Guide: The core advantage of the Compact model is speed—fast installation (1–2 days), quick delivery (4 weeks), and a rapid return on investment. If your project has a tight schedule or limited budget, or if you simply want to test the waters, the Compact is the safest choice. However, a U-value of ≤0.35 indicates the lowest thermal insulation performance among the six available configurations. If your site is located in a cold region or requires year-round use, we recommend considering the "Insulated" or "Luxury" models instead.

Configuration 2: Standard Garden Rooms (15-25m²)

Standard is the configuration we recommend most often at Deslano, and for good reason. It hits the sweet spot between usable space, thermal performance, and budget, making it the go-to choice for commercial buyers who want a reliable, versatile structure without over-engineering. At 15 to 25 square metres with enhanced double glazing and argon-filled cavities, it delivers comfort across three seasons in most European and North American climates.

Why is the "Standard" model our go-to, all-purpose choice? It strikes a balance across several key dimensions: ample space (comfortably accommodating 6–12 people within 15–25 m²), excellent thermal insulation (U-value ≤ 0.30; argon-filled insulated glass offers ~15% better energy efficiency than standard double glazing), and a moderate price point (higher than the "Compact" but far below the "Luxury" tier).

Key Specifications:

Area: 15–25 m²

Frame Material: 6063-T5 aluminum alloy (thickened wall profile)

Glass Configuration: Double-glazed tempered insulated glass (5mm + 16A + 5mm, argon-filled)

U-Value: ≤ 0.30 W/m²K

Installation Time: 2–3 days

Production Lead Time: 4–6 weeks

Suitable Commercial Applications:

Hotels: Outdoor lounge areas, breakfast rooms, small meeting spaces

Restaurants: Medium-sized private dining rooms (8–12 guests) or semi-open dining areas

Office Buildings: Small meeting rooms (6–8 people) or team collaboration spaces

Commercial Complexes: Pop-up stores, brand showcase spaces

Over 60% of our hotel clients choose the "Standard" model for their initial orders. As they put it: it hits the "sweet spot"—a balanced choice to get operations up and running and gauge performance. If you are unsure whether your project requires top-tier insulation, the "Standard" is the safest starting point; should an upgrade be needed later, Deslano can easily adjust the glass configuration.

Configuration 3: Luxury Garden Rooms (25-50m²)

Luxury is our top-tier configuration, built for projects where performance and scale are non-negotiable. With triple-glazed, Low-E coated glass achieving U-values as low as 0.20 W/m²K and a structurally reinforced aluminium frame, this configuration can handle large spans up to 50 square metres while maintaining near-passive-house levels of thermal insulation. It is the configuration we manufacture for high-end hotels, premium care homes, and corporate reception spaces where comfort and aesthetics must coexist.

The "Luxury" configuration represents the pinnacle of the Deslano product line. Simply put, it targets clients with uncompromising standards for quality—where "functional" isn't enough, and superior performance is a must. The combination of triple-pane insulated glass and Low-E coating achieves a U-value of ≤0.20. What does this level of thermal insulation mean? Even in an environment of -10°C, the interior temperature remains above 10°C without any heating. For markets with long winters—such as Scandinavia, Canada, and Northern England—this is not merely a bonus feature; it is an essential requirement.

Key Specifications:

Area range: 25–50 m²

Frame material: 6063-T5 aluminum alloy (structurally reinforced frame)

Glass configuration: Triple-pane tempered insulated glass (5mm + 12A + 5mm + 12A + 5mm, Low-E coating)

U-value: ≤0.20 W/m²K

Installation period: 3–5 days

Production lead time: 6–8 weeks

Suitable commercial applications:

High-end hotels: VIP reception lounges, spa areas, panoramic restaurants

Premium retirement homes: Sun-filled activity halls, rehabilitation and therapy rooms

Corporate headquarters: Executive conference rooms, client reception centers

Commercial clubs: Multi-functional banquet spaces, wine tasting rooms

The trade-off is straightforward: the production cycle is two weeks longer than the "Standard" version, and the cost is higher. However, our experience shows that for projects positioned in the mid-to-high-end market requiring year-round operation, the investment in the Luxury configuration pays off. Savings on energy costs cover the price difference within one or two operating seasons. A hotel client of ours in Scandinavia ran the numbers and found that they began realizing net savings starting in the second year.

Configuration 4: Modular Garden Rooms (10-30m²)

Modular is the configuration that breaks the traditional one-build-one-location model. Designed around a connectable unit system, modular garden rooms can be installed as a single 10m² pod or linked together to create up to 30m² of usable space. More importantly, they can be disassembled and relocated, which makes them the only configuration that works as a movable asset rather than a fixed installation. For chain operators and seasonal businesses, this flexibility is a game-changer.

The Modular configuration offers the greatest flexibility among our six options. Its core design philosophy is not to create a static space, but to provide a mobile, reconfigurable one. We developed the Modular line in response to feedback from numerous chain-store clients who needed a solution that could move with them. Deslano’s modular connection system allows units to function independently or be combined; assembly and disassembly can be completed within just a few days.

Key Specifications:

Area: 10–30 m² (single module: 10–15 m²; combinable up to 30 m²)

Frame Material: 6063-T5 aluminum alloy (modular connection structure)

Glazing: Double-glazed tempered insulating glass (5mm + 12A + 5mm)

U-Value: ≤0.35 W/m²K

Installation Time: 1–3 days (1 day for a single module; 2–3 days for combined units)

Production Lead Time: 4–6 weeks

Suitable Commercial Applications:

Chain Restaurants/F&B: Detachable outdoor dining areas (relocatable upon lease expiration)

Event Venues: Temporary exhibition spaces, seasonal sales areas

Schools: Expandable temporary classrooms (add modules as enrollment grows; remove them as it decreases)

Construction Sites: Project management offices (relocatable to the next site upon project completion)

The primary value of the Modular unit lies in its flexibility rather than having the highest technical specifications. It is the ideal choice if you are operating in a leased space, have needs that fluctuate with business volume, require rotation across multiple locations, or need to relocate assets after a project concludes. Its thermal insulation performance is comparable to the Standard model (U-value ≤0.35), with options to upgrade the glazing for superior insulation if required.

Configuration 5: Insulated Garden Rooms (15-35m²)

Insulated is the configuration we built specifically for one requirement: year-round commercial operation without the premium cost of Luxury. Using triple-glazed units and a thermally broken aluminium frame, it achieves a U-value of <=0.25 W/m²K, good enough for comfortable all-season use in most temperate and cool climates, at a price point roughly 15-20% below Luxury. For buyers who need performance but want to keep budgets reasonable, this is usually the configuration we point them to first.

The "Insulated" configuration is specifically designed to meet the need for year-round use. The difference between it and the "Luxury" option lies in the performance-to-cost balance: while "Luxury" targets peak performance (U-value ≤ 0.20), "Insulated" focuses on providing sufficient performance at a more economical price point (U-value ≤ 0.25). Although the 0.05 difference in U-value is barely perceptible in terms of thermal comfort, the cost difference is significant—ranging from 15% to 20%. For most commercial projects, the insulation level provided by the "Insulated" configuration is more than adequate. The core technology behind this configuration is Deslano’s thermal break frame structure; since aluminum conducts heat rapidly, the thermal break design incorporates an insulating strip within the frame to effectively block heat transfer paths.

Key Specifications:

Area range: 15–35 m²

Frame material: 6063-T5 aluminum alloy (thermal break structure)

Glass configuration: Triple-glazed tempered glass (5mm + 12A + 5mm + 12A + 5mm)

U-value: ≤ 0.25 W/m²K

Installation time: 2–4 days

Production lead time: 5–7 weeks

Suitable commercial applications:

Hotels: Outdoor tea rooms or breakfast areas for year-round operation

Retirement homes: Sunrooms for year-round activities (essential, given the elderly's sensitivity to temperature)

Office buildings: Outdoor workspaces for year-round use

Gyms: Outdoor training areas for year-round operation

Our recommendation to clients is straightforward: for temperate climates (most UK cities, the US West Coast), the "Insulated" configuration is perfectly adequate; for cold climates (Scandinavia, Canada, Russia), we recommend opting directly for "Luxury"; and if the space is intended for use only during spring, summer, and autumn, the "Standard" configuration suffices, making the extra investment unnecessary.

Configuration 6: All-Glass Garden Rooms (12-30m²)

All-Glass is the configuration that prioritises visual impact above everything else. With floor-to-ceiling tempered glass panels and minimal aluminium framing, it creates a fully transparent, light-filled space that turns heads. For hospitality and retail projects where the space itself is a marketing tool, All-Glass delivers an experience that no other configuration can match. The trade-off is thermal performance: with a U-value of <=0.40, it sits at the bottom of the insulation ranking.

The "All-Glass" configuration is the most visually striking of the six options. The structure utilizes extensive tempered glass panels with a minimized frame footprint, creating an exceptionally transparent and open visual effect. We once worked on a high-end restaurant project where the owner’s reason for choosing the All-Glass option was simple: the ability for guests to enjoy a 360-degree view of the garden and sky while seated was a major selling point in itself. For commercial projects that rely on a sense of spaciousness to attract customers, this configuration offers the greatest visual impact. Deslano’s narrow-frame aluminum alloy structure minimizes the visible frame width while maintaining structural integrity.

Key Specifications:

Area range: 12–30 m²

Frame material: 6063-T5 aluminum alloy (narrow-frame design to maximize glass area)

Glass configuration: 12mm tempered glass panels (laminated safety glass optional)

U-Value: ≤0.40 W/m²K

Installation time: 2–3 days

Production lead time: 5–6 weeks

Suitable Commercial Applications:

High-end restaurants: Panoramic dining spaces (360-degree outdoor views)

Hotels: Lobby lounges, rooftop gardens, scenic rest areas

Retail: Transparent display spaces for flagship stores

Event venues: Wedding ceremony areas, product launch sites

The key trade-off is that while it offers the most impressive visual impact, it has the lowest thermal insulation performance among the six configurations (U-value ≤0.40). This is a matter of physics: the larger the glass surface area, the more challenging thermal insulation becomes. Deslano’s recommendation: The All-Glass option is ideal for warm climates or seasonal summer operations. For year-round use in cold regions, consider upgrading to triple-glazed glass (a customization we have previously executed). It is less suitable for settings requiring a high degree of privacy—given that all four sides are made of glass.

How to Choose the Right Configuration for Your Project

Understanding the 6 configurations is one thing; knowing which one fits your specific project is another. In this section, we have mapped the most common commercial project types to their best-fit configurations, along with the reasoning behind each recommendation. We also cover the mistakes we see buyers make most often so you can avoid them.

When selecting a configuration, the most expensive option isn't necessarily the best; the best choice is the one that is the best fit. The following mapping table summarizes the Deslano team's years of experience serving commercial clients; you can refer directly to it to find recommendations based on your project type.

Project Type to Configuration Recommendation

This chart serves as a starting point, not the final word. When making your actual selection, you also need to consider local climatic conditions, site foundation requirements, your budget, and whether planning approval is required.

Common Mistakes When Selecting a Garden Room Configuration

Having operated a factory for years, we’ve seen far too many clients take the wrong path when selecting configurations. Here are the four most common pitfalls—each backed by real-world examples.

Pitfall 1: Focusing solely on size while ignoring thermal insulation

This is the most common mistake. Many clients immediately ask for the maximum possible square footage and choose the largest option. However, without proper insulation, a larger footprint leads to higher energy consumption and operational costs that will become a headache later on. The right approach is to first determine your intended season of use and local climate conditions, then select the appropriate insulation grade. You can adjust the size later, but you can't easily upgrade the insulation.

Pitfall 2: Failing to consider site foundation requirements

Different configurations have different foundation requirements. The "Luxury" configuration (25–50 m²), due to its large size and heavy structure, requires a concrete foundation; in contrast, "Compact" and "Modular" models can be placed on existing decks or paved surfaces. If site conditions are limited, your chosen configuration might incur extra foundation costs—an expense that should be factored in from the start.

Pitfall 3: Overlooking the impact of installation time on the project schedule

If your project has a specific opening date or delivery deadline, the installation period must be part of the plan. The "Luxury" configuration requires 3–5 days for installation plus a 6–8 week production lead time, totaling 2–3 months; the "Compact" model, however, needs only 1–2 days for installation and a 4-week lead time, meaning it can be ready within five weeks. This timing difference can determine whether you open in time for peak season or miss the opportunity.

Pitfall 4: Limiting configuration choices based on intended use

"I want a gym"—this mindset leads you to jump straight to a specific configuration rather than objectively evaluating all options. Perhaps a "Modular" configuration (which offers flexible size adjustments) would actually be better suited for your gym than the "Standard" model. Evaluate the specifications first, then determine the use case.

Customization Options: What Can Be Adjusted

The 6 configurations above are our standard specifications, but they are far from fixed. At Deslano, we have spent over a decade customising garden rooms for commercial projects, and almost every parameter can be adjusted to match your specific requirements. Here is what is typically flexible, so you know what is possible before you start the conversation with us.

The six configurations mentioned above represent our standard product offerings, but they are not set in stone. With over a decade of experience in custom manufacturing, Deslano offers flexibility regarding almost every specification. Here are the customization options we handle most frequently:

Custom Dimensions:

Length and width can be fine-tuned to fit the specific site conditions.

Height can be adjusted based on site constraints (standard height is 2.4m; options range from 2.2m to 2.8m).

Non-standard shapes (such as L-shaped or curved designs) are possible, though they require specific structural drawings.

Glass Upgrades:

Standard configurations can be upgraded to triple glazing (improving the U-value to ≤0.25).

All-Glass configurations offer an option for laminated safety glass (providing enhanced safety, ideal for high-traffic areas).

All configurations can be fitted with UV-blocking film or switchable smart glass (electrochromic).

Frame Colors:

Standard colors: Matte black, frosted gray, and white (no extra charge).

Custom colors: Color matching based on RAL codes (MOQ of 200 units; lead time increases by one week).

Wood-grain finish: Aluminum surfaces treated with a wood-grain effect (visual appearance of wood frames while maintaining aluminum performance).

Roof Styles:

Flat roof (standard configuration; suitable for most commercial settings).

Single-slope roof (facilitates drainage; suitable for rainy regions).

Gabled roof (traditional aesthetic; suitable for high-end hotel projects).

These customization options allow you to refine our six standard configurations into a solution that perfectly matches your project's requirements. If you have your own design drawings or concepts, simply send them to the Deslano engineering team; we will evaluate their feasibility and provide you with feedback.

FAQ: Garden Room Types & Configurations

Below are the questions we get asked most often by commercial buyers when they are exploring garden room types and configurations. Each answer includes specific data so you can use it directly in your project discussions.

Q1: What is the most popular garden room configuration for commercial projects?

The Standard configuration (15-25m²) is the most frequently ordered for commercial use. It balances usable space with cost efficiency, using double-glazed panels with U-values <=0.30 and 6063-T5 aluminium frames. Hotels and restaurants typically start with this configuration for outdoor dining areas or guest lounges.

Q2: Can garden room configurations be customized beyond the 6 standard types?

Yes. All 6 configurations serve as baseline specifications. Dimensions can be adjusted within structural limits, glass types can be upgraded, and frame finishes can be matched to your project colour scheme. Our factory produces custom specifications based on your architectural drawings and site requirements.

Q3: What is the minimum order quantity (MOQ) for commercial garden room orders?

MOQ depends on the configuration type. Standard and Compact configurations typically start from 1 unit for trial orders. For project orders involving 5+ units, we offer volume pricing and dedicated project management. Lead time for single units is 4-6 weeks; multi-unit orders may require 6-8 weeks.

Q4: Which garden room configuration is best for year-round commercial use?

For year-round operation, we recommend either the Insulated configuration (U-value <=0.25, triple glazing) or the Luxury configuration (U-value <=0.20, triple glazing). These minimize heating and cooling costs while maintaining comfortable interior temperatures in all seasons.

Q5: Do you provide certification documents for commercial garden rooms?

Yes. All configurations come with material test reports for the 6063-T5 aluminium frames, glass certification, and structural load calculations. We can also provide CE marking documentation for European markets and assist with local building regulation compliance upon request.
