BUYING GUIDE · GARDEN ROOMS
Plan the room you need before choosing its size
A garden room works best when its layout, construction and services are designed around a clear purpose. Use this guide to develop a brief that goes beyond external dimensions and an attractive photograph.
1. Define the primary use
Will this be a daily office, gym, creative studio or family room? List the activity that needs the most space, then any secondary use. A room that tries to do everything may do none of it comfortably.
State any intention to use the building for sleeping or independent accommodation from the outset. That is a different brief from a daytime garden room and needs a project-specific assessment of design, services and approvals.
2. Test the furniture and circulation
Draw the desk, chair movement, storage and equipment. Allow clear space at doors and around furniture. For a gym, include the clearances and loading requirements of the equipment you intend to use.
Check internal dimensions after walls and finishes are allowed for. External footprint alone can be misleading when comparing buildings with different construction thicknesses.
Use the compact, medium and large garden room guides to compare useful layouts rather than fixed product names.
3. Choose a position that works in real life
Consider the view from the house, privacy, daylight and the garden you want to retain. Leave practical access for maintaining the building and managing rainwater.
The route to the room matters on a wet morning as much as on a summer afternoon. Paths, steps, thresholds and exterior lighting can make the space easier to use throughout the year.
Delivery and installation access should be measured. Narrow side passages, steep levels and limited storage space can affect the construction approach and programme.
4. Understand the whole construction
Ask about the foundation or support system, frame, floor, walls, roof, insulation and weather-control layers. The cladding is only the visible finish of a larger assembly.
Heating, ventilation and glazing should be considered alongside insulation. A highly glazed gym and a small office used all day have different practical needs.
Check the proposed roof covering and rainwater route. Maintenance access and the treatment of corners, thresholds and roof edges are worth understanding before ordering.
5. Make a services checklist
| Power | Supply route, available capacity, sockets and equipment requirements. |
|---|---|
| Lighting | Task lighting, general lighting and the route from the house. |
| Comfort | Heating, ventilation, glazing and any shading. |
| Connectivity | A dependable data connection where working or streaming is planned. |
| Water and drainage | Separate assessment and pricing for any kitchenette, WC or shower. |
Confirm who supplies and installs each element. Do not assume that fully finished includes every service or furnishing you have in mind.
6. Confirm requirements before a build date
The appropriate planning and building requirements depend on the property, design, location and intended use. Establish the required advice, applications and documentation for your project instead of relying on a general statement that garden rooms need no permission.
Agree responsibility for this work and any costs before installation is scheduled. An intended annex should be assessed as accommodation rather than treated as a garden office with extra furniture.
7. Compare the completed scope
Include preparation, base, structure, glazing, cladding, roof, internal finishes, services and external works. Ask what is excluded and how changes are agreed.
Keep the surrounding garden in the budget. A simple path and adjoining terrace can make the building much more useful than a slightly larger room with no practical route to it.
