Permitted Development for House Extensions: The Complete Guide

Many house extensions don't need planning permission. Here's what you can build under permitted development rights.

Permitted development rights allow homeowners to make certain changes to their properties without applying for planning permission. For house extensions in Yorkshire, this can significantly simplify and speed up the process.

Under Class A permitted development, a single-storey rear extension can extend up to 3m beyond the original rear wall for a semi-detached or terraced house, or 4m for a detached house, subject to height and design conditions. Under the larger home extension scheme (prior approval), these limits can be extended to 6m and 8m respectively.

However, permitted development rights are removed in conservation areas (for side extensions and roof alterations), for listed buildings (where listed building consent is always required), and in Article 4 Direction areas. Many older homes in Yorkshire's towns and villages are subject to these restrictions.

Our architects will carry out a thorough assessment of your property's permitted development rights as part of our initial consultation, ensuring you understand exactly what can be built without a planning application.
