Two-storey rear extension in Newcastle upon Tyne
For homes in Newcastle upon Tyne, 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.
We cover Newcastle upon Tyne (NE3, NE4, NE5 and NE6) as part of our Tyne and Wear work. Two-storey rear extensions suit semi-detached houses in Newcastle upon Tyne best, where the extra bedroom matters as much as the bigger kitchen.

Do you need planning permission for a two-storey rear extension in Newcastle upon Tyne?
Whether your two-storey rear extension in Newcastle upon Tyne needs a planning application depends on its size, your house and any local restrictions.
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. We check your house's planning history and any conservation area before drawing, so the route is clear before you spend on plans.
What are homes in Newcastle upon Tyne like to extend?
Terraces and semis are typical around Newcastle upon Tyne. On terraces a single-storey rear extension across the back yard is usually the practical choice; semis often have room for more.

FAQ
Two-storey rear extension questions in Newcastle upon Tyne
Is the site visit in Newcastle upon Tyne free?
Yes. We visit, measure up and talk through the options with no cost and no obligation.
Will I need a structural engineer?
Yes for the beam over the new opening and usually the foundations; we arrange them and their calculations go to building control.
Can it be built on a terraced house?
Sometimes, but the upper floor is harder to get through planning on a terrace because of the effect on neighbours. A single-storey extension with a loft conversion is often an easier route.
Can you match the brick or stone on my Newcastle upon Tyne house?
We source the closest match and show you samples before ordering; reclaimed materials are often the best match on older houses.
Do I need a party wall agreement?
In England, usually yes if the extension is on or near a shared boundary or the foundations are close to a neighbour's building. We serve the notices.
