Planning Permission & Permitted Development
Many garden rooms fall under permitted development rights, meaning planning permission is often not required.
We will advise you clearly on:
-
Permitted development limits
-
Height and boundary rules
-
Use as a habitable space
-
When planning permission may be required
Our expert guidance ensures your garden room is designed correctly from the outset, avoiding costly mistakes or delays.
Our Design & Build Process (Free Consultation)
We provide a fully guided, stress-free process from the first conversation to final handover.
1. Free Home Consultation & Design Guidance
We begin with a FREE, no-obligation home visit, where we:
-
Discuss your ideas and requirements
-
Assess your garden and access
-
Advise on permitted development & regulations
-
Talk through layouts, finishes, and budgets
During this visit, we also create AI Generated images to show you exactly what your garden room will look like when complete. This allows you to visualise the finished project before any work begins.
This design service is completely FREE of charge.
2. Bespoke In-House Design
Every garden room is designed in-house, not selected from a brochure. This allows us to tailor:
-
Size & layout
-
Window & door placement
-
Insulation levels
-
Internal finishes
-
Kitchen & bathroom layouts (if required)
No two garden rooms are ever the same.
3. Construction – Built On Site from Scratch
We construct your garden room entirely on-site, using methods found in timber-framed houses and extensions, not flat-pack systems.
The build process typically includes:
-
Groundworks & foundations
-
Timber frame construction
-
Roof structure & coverings
-
High-performance insulation
-
Doors & windows installation
-
First & second fix electrics (Part P)
-
Plumbing, drainage & water supplies
-
Plastering & internal finishes
-
Final inspections & sign-off
This approach delivers a stronger, warmer, and longer-lasting garden room compared to panel-built alternatives.
4. Project Management, Programme & Payment Plan
Every project includes:
A clear build programme
Agreed timescales
A structured payment plan
All project management is handled in-house by GCM Property Services, ensuring smooth coordination of trades and consistent quality control.
We manage the entire process from start to finish, so you don’t need to deal with multiple contractors.
