What do rear extension planning drawings cost in Monmouth?
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 Monmouth?
The planning route for a rear extension in Monmouth is set by Wales's householder rules and your council.
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. Before any drawing we look up the property's history with the council, because earlier extensions and removed rights change the answer.
What are homes in Monmouth like to extend?
Older terraces near the centre and post-war semis further out are typical of Monmouth. Sloping sites are common in Wales, so floor levels and retaining walls are designed at the start.

FAQ
Rear extension planning drawings questions in Monmouth
Can I live at home while the extension is built?
Usually yes. Most of the work is outside until the back wall is opened near the end, and that stage is screened off.
Can you match the brick or stone on my Monmouth house?
We source the closest match and show you samples before ordering; reclaimed materials are often the best match on older houses.
Can planning conditions affect the build?
Yes, for example matching materials or obscure glazing. We plan for them.
Who will build my extension?
Vetted building teams working under contract to us. Your contract is with S&K Property Investments and Improvement Ltd for the design and the build.
