Two-storey rear extension in Maesteg
For homes in Maesteg, a two-storey rear extension is often the simplest way to gain space without moving. A larger kitchen downstairs and an extra bedroom or bathroom upstairs, under one roof. We take it from survey to completion certificate.
Maesteg is covered from our South Wales Valleys round, including CF34. Two-storey rear extensions suit semi-detached houses in Maesteg best, where the extra bedroom matters as much as the bigger kitchen.

Do you need planning permission for a two-storey rear extension in Maesteg?
Planning for a two-storey rear extension in Maesteg 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.
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 Maesteg like to extend?
Maesteg 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.

Usually yes. Most of the work is outside until the back wall is opened near the end, and that stage is screened off.
Is the site visit in Maesteg free?

Yes. We plan the soil pipe route early so the bathroom sits where drainage works without boxing through the room below.
