Do you need planning permission for a bungalow rear extension in Rhondda?
Whether your bungalow rear extension in Rhondda needs a planning application depends on its size, your house and any local restrictions.
In Wales a single-storey rear extension can often be permitted development if it projects no more than 4 metres beyond the rear wall and is no more than 4 metres high. Wales has no prior approval route for deeper extensions, so anything bigger needs a householder planning application.
Conservation areas, National Parks and National Landscapes restrict permitted development in Wales, and listed buildings need listed building consent. We check your house's planning history and any conservation area before drawing, so the route is clear before you spend on plans.
What are homes in Rhondda like to extend?
Rhondda is largely terraced streets on sloping ground, where back gardens step up or down from the house. Excavation, retaining walls and drainage are priced at the survey.

Our online guide-price tool gives a range in a couple of minutes. A written price needs a survey.
Is the site visit in Rhondda free?
Yes. We visit, measure up and talk through the options with no cost and no obligation.
