What do rear extension planning drawings cost in Abertillery?
As a guide, £1,000–£2,500 including VAT for a single-storey rear extension, or £2,000–£3,500 for a two-storey scheme. Planning fees in Wales are set by the Welsh Government; we confirm the current householder fee when we prepare the application. These are guide ranges; the written quote after the survey is the figure that counts.
Do you need planning permission for a rear extension in Abertillery?
Planning for a rear extension in Abertillery follows the Welsh householder rules.
Welsh rules allow a two-storey rear extension without an application only where the ground floor is no deeper than 4 metres, the upper floor no deeper than 3 metres and at least 10.5 metres remains to the rear boundary. Most homeowners still apply for householder planning permission.
Welsh councils aim to decide householder applications within 8 weeks.
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 Abertillery like to extend?
Abertillery 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.
