Need A Different Size?

We Don't Build Around A Size List. We Build Around Your Garden.

These dimensions are pricing examples rather than fixed models. Oakspan can create different widths, depths, layouts and glazing configurations around your available space and how you intend to use the building.

How Our Pricing Works

Guide Price First. Fixed Price Before We Build.

The prices above give you a realistic starting point. Once the site, room design, specification and any bespoke features have been agreed, Oakspan provides a clear fixed-price quotation for the project you actually want.

Prices shown are guide starting prices for the example room sizes and are not quotations. Final pricing depends on the agreed design, project specification, site conditions and bespoke requirements.

Standard Garden Room Specification

What's Included In Your Oakspan Garden Room?

Your starting price is based on a properly specified, insulated garden room designed for genuine everyday use — not a basic shell that needs essential building elements added later.

Built In From The Start

The important parts of the building are considered before your quotation is agreed — from the base and structure to insulation, glazing, electrics and finishes.

01

Foundations & Structure

The building starts with the appropriate prepared base and structural system for the agreed room design and site, creating a solid foundation for the complete Oakspan build.

Core Build
02

Roofing

The roof forms part of the complete room specification, designed around the building itself and to provide reliable long-term protection from the Scottish weather.

Weather Protection
03

Insulation

Walls, roof and floor are designed as an insulated building envelope, helping create a garden room suitable for regular use throughout the changing Scottish seasons.

Year-Round Building
04

Doors & Windows

Double-glazed doors and windows are incorporated into the agreed design, with their position considered around light, views, access and how you intend to use the room.

Agreed Glazing Layout
05

Electrical Provision

Power and internal lighting are planned as part of the specification, with the final electrical layout shaped around how your finished room will actually be used.

Planned Around Use
06

Exterior & Interior Finish

Your Oakspan is delivered as a properly finished room, with exterior and interior finishes forming part of the agreed specification rather than being treated as an afterthought.

Finished Space

The Oakspan Approach

Included Means Included.

Your exact standard specification is agreed and documented before Oakspan issues the final fixed-price quotation, so you know what forms part of the building before construction begins.

Want To Take The Room Further?

That's Where The Bespoke Part Begins.

Heating and cooling, kitchens, WCs, showers, specialist glazing, golf simulator requirements, saunas, canopies, technology and other bespoke features can all be designed into your Oakspan and priced as part of the final quotation.

Explore Bespoke Extras

Exact specifications vary according to room design, project requirements and site conditions. Optional and upgraded elements are identified separately and agreed within your quotation before construction begins.

Bespoke Garden Room Extras

Make It Yours.

Start with a properly specified Oakspan garden room, then add the features that matter to how you actually want to use the space. Your choices are incorporated into the design and priced before the final quotation is agreed.

Designed Around You

An office needs something different from a golf room. A gym needs something different from an annexe. That's why the specification can be shaped around you.

01

Heating, Cooling & Smart Comfort

Add efficient hot-and-cold climate control for greater year-round comfort — particularly useful for offices, gyms, golf rooms, music studios, yoga spaces and garden living rooms.

Optional Upgrade Heating & Cooling From £950

02

Kitchen & Annexe

Add practical facilities that allow your garden room to operate more independently from the main house and support longer stays or more flexible everyday use.

Bespoke Without The Unknowns

Bespoke Doesn't Mean Uncontrolled Costs.

Every optional feature — including heating and cooling supplied and fitted from £950 — is designed, specified and priced before your final quotation is agreed. Once the project scope is signed off, those additions form part of the fixed-price build.

Discuss Your Garden Room Explore Real Projects

Heating and cooling systems are supplied and fitted from £950. Final system specification and price depend on room size, intended use and project requirements. Other bespoke features are also subject to design, site conditions and final specification.

Optional Heating & Cooling

Comfortable In January. Comfortable In July.

If your Oakspan will be used as an office, gym, golf room, studio, wellness space or living room, you may want greater control over the temperature. Hot-and-cold climate control can be supplied and fitted from £950.

Scotland's Highest Recorded Temperature 34.8°C

Scotland reached 34.8°C at Charterhall in July 2022. A well-insulated garden room can still become warm when sunshine, glazing, people and equipment combine.

Oakspan Heating & Cooling Upgrade From £950

Add a hot-and-cold climate-control system to your Oakspan supplied and fitted from £950. The system is specified around the room size, intended use and project requirements.

01

Garden Offices

Computers, monitors, people and solar gain can all increase internal temperature during a working day. Climate control lets you adjust the room rather than simply opening a window.

02

Home Gyms

Exercise quickly changes how warm a space feels. Cooling gives you more control during a workout, while heating can make early winter sessions more inviting.

03

Golf Rooms

Projectors, computers, lighting and several people can generate additional heat in an enclosed simulator room, particularly during longer sessions.

04

Music & Studio Rooms

Audio equipment, computers and acoustic requirements can make temperature control particularly useful when opening windows is not the preferred option.

05

Yoga & Wellness

Different activities call for different conditions. Heating and cooling give you greater control over the atmosphere rather than relying on the weather outside.

06

Living & Annexe Spaces

When a garden room becomes an extension of everyday living, controllable heating and cooling can help it feel more like another room of the home.

Fixed-Price Garden Rooms

Why Fixed Price Matters.

A fixed price only works when the important decisions are made first. Oakspan agrees the room, specification and project scope before construction begins.

The Simple Principle

Guide price first. Design and specification next. Fixed-price quotation before we build.

Garden Room Pricing FAQs

Questions About Garden Room Costs.

The most common questions about Oakspan prices, standard specification, bespoke options and how the fixed-price quotation works.

How much does an Oakspan garden room start from?

Oakspan garden rooms currently start from £15,000 for a 4m × 3m room. This provides a 12m² starting point, with larger and bespoke room sizes available.

What does “from £15,000” mean?

£15,000 is the guide starting price for the 4m × 3m example room. Your final quotation depends on the site, design, specification and any bespoke features you choose. Once those are agreed, Oakspan provides the fixed-price quotation for your project.

What is the smallest Oakspan garden room?

Oakspan's current garden room range starts at 4m × 3m, or 12m². From there, the building can be designed larger or around dimensions that better suit your garden and intended use.

What is included in the starting garden room price?

The starting specification is based on a properly built and insulated garden room, including the agreed base and structure, roofing, insulated building envelope, double-glazed doors and windows, electrical provision and agreed finishes. The exact specification is documented before the final quotation is issued.

Is heating and air conditioning included?

No. Heating and cooling is an optional upgrade. Oakspan can supply and fit a hot-and-cold climate-control system from £950, with the final system selected around the room size, intended use and project requirements.

Can I add a kitchen, WC, shower or sauna?

Yes. Oakspan can incorporate bespoke elements such as kitchens, hot water, WCs, showers, saunas, specialist glazing, canopies, golf simulator requirements and other features. These are designed and priced before the final project quotation is agreed.

Do Oakspan garden rooms have to be standard sizes?

No. The room sizes shown on this page are useful pricing examples rather than a fixed catalogue. Oakspan can design different widths, depths, layouts and glazing configurations around your available space and how you plan to use the room.

Can the price change after I accept the quotation?

The quotation is based on the agreed design and project scope. If you later request changes or additional work, the price may need to be updated. Any such changes would be discussed and agreed before the additional work proceeds.

How long does an Oakspan garden room take to build?

Build time depends on the size, site and complexity of the project. Compact garden rooms can be completed more quickly, while larger rooms and specialist projects naturally require longer. The expected build programme is discussed as part of your project planning.

How do I get an accurate price for my garden room?

Tell Oakspan where you are, approximately how much space you have and what you want the room to be used for. We can then discuss the design, specification and any bespoke features before preparing your project quotation.
