Two-storey rear extensions in the Isle of Wight
A larger kitchen downstairs and an extra bedroom or bathroom upstairs, under one roof. Rear extensions in the Isle of Wight: we cover 6 towns including Newport, Ryde and Cowes, with design, approvals and the build under one contract.
Island and remote addresses in the Isle of Wight are by arrangement: we confirm whether we can take the job, and agree any travel costs, before the first visit.
Two-storey rear extensions suit semi-detached houses in Newport best, where the extra bedroom matters as much as the bigger kitchen. Around Isle of Wight the housing ranges from inter-war semis to 1960s and 1970s estates with good-sized gardens. Many of the newer estates had permitted development rights removed by condition, so we check the planning history before anything is drawn.

Do you need planning permission in the Isle of Wight?
England's rules allow a rear extension of more than one storey without an application only when it is no deeper than 3 metres and at least 7 metres from the boundary opposite the rear wall, and never on designated land. Most two-storey schemes need householder planning permission.
Conservation areas, National Parks, National Landscapes and the Broads restrict permitted development, and listed buildings always need listed building consent.

FAQ
Questions people ask
Does a two-storey rear extension need planning permission?
Almost always. England and Northern Ireland allow 3 metres without an application only if at least 7 metres remains to the rear boundary; Wales and Scotland are similar or stricter.
Is two-storey cheaper per square metre than single-storey?
Usually yes, because the foundations and roof are shared across twice the floor area. The total cost is higher.
Can I add an en-suite upstairs?
Yes. We plan the soil pipe route early so the bathroom sits where drainage works without boxing through the room below.
Do you cover all of the Isle of Wight?
We cover 6 towns and districts in the Isle of Wight, including Newport, Ryde and Cowes. Remote and island addresses are by arrangement.
