Year-round workspaces
Garden Office SIP Shell Kits
A warm, airtight SIP shell route for home offices, studios and quiet workspaces where speed and predictable kit contents matter.
Likely starting point
122mm for many non-habitable garden offices; 172mm where Building Control, higher performance or habitable use may apply.
Most customers know they want a garden office, but they are unsure which panel thickness, roof build-up and floor route makes sense.
Next best step
Not sure whether to configure, send drawings, or check planning?
For garden office projects, the right route depends on how much detail you already have. Choose the closest option and we will keep the next step clear.
Build it online
Use the configurator when you know the footprint, roof style and rough opening positions.
Send it to us
Upload plans, sketches, window sizes or an old quote and we will price the SIP shell with clear assumptions.
Check the route first
Answer a few practical questions about use, height, boundary distance and location before ordering.
What can be included
Why SIP for this project
Why this route works as a SIP build
SIP panels create a warm, airtight shell quickly, so the office is easier to heat in winter and keep comfortable through the working day.
The structure arrives as a clear shell package rather than a loose timber-frame build-up, reducing guesswork around insulation, splines and fixings.
Openings can be planned around the doors and windows you want to use, keeping the workspace practical without forcing a one-size-fits-all layout.
Useful upgrades
- SIP floor package
- EPDM roof bundle
- Installation partner quote
- Opening-ready panels for supplied windows and doors
Checks before ordering
- Outbuildings are often permitted development if they meet height, location and use limits.
- If the building will be slept in or used as self-contained accommodation, treat it as a higher-risk Building Control route.
- If the building sits within 2m of a boundary, height control is usually the key early check.
