| Premium package | Platinum package | |
|---|---|---|
| Doors | Dark grey aluminium, triple glazed: French doors up to 4m wide, bi-folds above | Same doors |
| External cladding | Redwood, 18 × 95mm | Thermowood, 20 × 118mm tongue and groove |
| Interior walls | Whitewash redwood cladding | Painted plasterboard, or a free acoustic panel or redwood finish |
| Flooring | SPC (stone plastic composite) | Engineered natural oak, matt lacquered |
| Wall insulation (timber frame) | 75mm Rockwool | 100mm Rockwool |
| Floor insulation (timber frame) | Thinsulate foil | 90mm foil-backed Celotex |
| Heating and cooling | Smart air conditioning | Smart air conditioning or an Adax NEO panel heater |
| Switches and fittings | White, standard switches | Brushed stainless, dimmer switch |
| Fuse box | Internal consumer unit | External weatherproof consumer unit |
Signature Collection rooms can also be built with structural insulated panels (SIPs) instead of a timber frame; the Heritage is traditional timber stud.

Costs to budget for on top
- The base. A concrete base or ground screws is not included. We survey the site, advise on which it needs and can quote for it.
- Power from the house. An electrician runs an armoured cable from your fuse board to the room. Cost depends on the distance.
- Level, clear ground and access. The ground needs to be level and the site reachable for installation; your design consultant will check this on the survey.
- Optional upgrades. On the Heritage Collection, a veranda adds from £1,150 and a store deck from £1,600, depending on the building's width, and upgraded flooring is £85 per m².
Questions about garden room costs
How much does the cheapest Crown Pavilions garden room cost?
The Heritage Collection starts at £23,750 for a 4m × 3m room with a flat roof, including VAT, delivery and installation.
Does the price include installation?
Yes. Every price in this guide includes delivery and professional installation by our own teams. The base (a concrete slab or ground screws) is not included and is quoted separately after a site survey.
Do I need planning permission for a garden room?
Our garden rooms are designed to comply with permitted development in most cases, so most do not need planning permission. Height, distance from the boundary, listed buildings and conservation areas can change that, so check with your local planning authority before you order. Our planning permission guide explains the rules.
Can I spread the cost of a garden room?
Yes, finance is available, subject to status. Crown Pavilions Limited is a credit broker, not the lender. See our finance options page for the plans and representative examples. Finance options.
Why do older articles show different garden room prices?
Prices change with each new range. This guide uses the 2026/27 prices from each model's own pricing guide and replaces our older articles on garden room costs.
