Many Permitted Development (PD) rules refer to the original dwellinghouse. Understanding what counts as the original house is essential, because it affects how much you can build, where you can build and which rules apply.
Get a clear picture of your property before choosing your drawings.
For PD purposes, the original house means the dwellinghouse as it was first built, or as it stood on 1 July 1948, whichever is later.
Later extensions and additions are not part of the original house. This matters because several PD limits — including the 50% rule for extensions — are calculated by reference to the original house.
The size, position and extent of your proposed development is often limited by the size and footprint of the original house. Knowing what is — and isn’t — part of the original house helps us work out what you may be able to build under PD.
Here are some typical situations and whether they form part of the original house.
For PD rules, the dimensions of the original house are taken from the external walls, including any attached integral garage, but excluding later extensions and additions.
Builder-ready drawings supplied exactly as sold.
We’ll assess your property, apply the relevant PD rules and help you configure the right design 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.
