A conservatory can add valuable living space and bring more light into your home. In many cases, a conservatory can be built under Permitted Development (PD) without a full planning application.
See what you could build at your home and choose the right drawing package.
Conservatories generally fall under Class A of the Permitted Development Order. The main limits are set by the conservatory’s size, height, position and use, with additional rules for listed buildings, conservation areas and homes near a highway.
Your conservatory must comply with all of the relevant PD rules. If any single limit is exceeded, a normal planning application may be required.
A range of conservatory designs can often be built under PD, including:
Lean-to conservatoryA simple, modern design with a sloping roof.
Victorian conservatoryA classic style with a multi-faceted front and pitched roof.
Edwardian conservatoryA square or rectangular design with a pitched roof.A conservatory must not extend more than 3 metres beyond the rear wall of the original house (or 4 metres for a detached house). The maximum height is 4 metres.
A conservatory must be to the rear of the original house and must not be forward of the principal elevation (including any side elevation facing a highway).
Materials should be of a similar appearance to the existing house and be of a high quality design.
A rear conservatory creating a light and spacious living area — built within PD limits.

We will check your property, apply the relevant Permitted Development rules and help you configure the right design and drawing package for your home.
Permitted Development rights described on this page apply to houses in England under the Town and Country Planning (General Permitted Development) (England) Order 2015. Different planning rules apply in Scotland, Wales and Northern Ireland. This page is general guidance, not a formal planning determination — always check your own property and, where you need certainty, apply to your local planning authority for a Lawful Development Certificate.
Each one is already drawn. You choose the material, roof and options we actually draw, and that is the package you receive.
