What do rear extension planning drawings cost in Risca?
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. Ground conditions, glazing, the roof and how far the house is opened up move the final figure within the range.
Do you need planning permission for a rear extension in Risca?
Whether your rear extension in Risca needs a planning application depends on its size, your house and any local restrictions.
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. At the first visit we measure what is there now and tell you which route fits: permitted development or a householder planning application.
What are homes in Risca like to extend?
Stone terraces along the valley floors and post-war semis higher up are typical of Risca. Sloping sites are common, so floor levels and retaining walls are designed at the start.
