Your project
Will it fit, and do I need planning?
Will it fit?
A consultation, your way
Talk through size, position and access with a design consultant. We can prepare a scaled drawing of your garden with your Heritage in place.
A site survey before installation confirms the right base for your garden.
Planning guidance
Do I need planning permission?
The Heritage is designed to comply with permitted development in most cases. As a guide:
- Up to 2.5m high if within 2m of a boundary
- Further away: up to 3m, or 4m with a dual-pitched roof
- Not in front of the house, and no more than half the garden built on
- Sleeping or living in it needs planning permission
- Heritage heights: 2.5m flat roof; 3.0–3.5m pitched, as drawn on the live drawings (other sizes TBC)
Guidance only. Check the Planning Portal or your local planning authority before you build.

Stunning bespoke Sandringham garden room
“Crown constructed a bespoke Sandringham garden room for us, to house a gym and sound proofed rehearsal studio. They are an absolutely brilliant company who provided a first class service from the first to the last engagement.”
Customer · Verified · Feb 2026★★★★★
Choosing the right provider
“Choosing the right provider for our garden room took some time, but opting for the Crown Sandringham turned out to be an excellent decision! We're thrilled with it; it has truly transformed our space.”
Customer · Jan 2026★★★★★
Customised Garden Room Project
“We are very pleased we chose Crown Pavilions for our garden room project. The whole experience has been excellent from customisation of the design, quality and speed of the build and excellent communication throughout.”
Customer · Oct 2024Real garden-room reviews from crownpavilions.com (Oct 2026); none names the Heritage. Heritage-specific reviews: TBC. The build would use the live Trustpilot feed.
What sizes does the Heritage come in?
From 3m × 3m up to 6m × 4.5m, in half-metre steps. Choose your size in the design generator above.
Flat or pitched roof?
Both. The flat roof has a single-piece EPDM membrane. The optional pitched roof, in asphalt tiles or cedar shingles, adds a front gable dormer and more headroom. Prices for both are shown for every size above.
Is there a mezzanine option?
Crown's 3D planner offers a mezzanine on the pitched-roof Heritage. Which sizes it suits and its price at most sizes are to be confirmed by your design consultant.
Do I need planning permission?
In most cases, no. The Heritage is designed to comply with permitted development, though there are exceptions depending on where you live and where you build.
Will I need a base?
Yes: a concrete base or ground screws. We carry out a site survey to assess which suits your garden, and quote groundworks separately.
Is installation included?
Yes, by our in-house specialist teams, within 100 miles of our Oxfordshire workshops. Beyond that, a travel surcharge applies.
