What do rear extension planning drawings cost in Caerleon?
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 Caerleon?
Whether your rear extension in Caerleon needs a planning application depends on its size, your house and any local restrictions.
In Wales a rear extension of more than one storey can be permitted development if the ground floor projects no more than 4 metres and the upper floor no more than 3 metres, with at least 10.5 metres to the rear boundary. It is not permitted development in conservation areas, National Parks or National Landscapes, so many double-storey schemes need a householder application.
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 Caerleon like to extend?
Older terraces near the centre and post-war semis further out are typical of Caerleon. Sloping sites are common in Wales, so floor levels and retaining walls are designed at the start. For Caerleon homes we start with a measured survey, then draw options before anything is submitted.
