Single-storey extensions case studies:

Avon Grove


Extending your home out on just one level could provide you with much-needed extra space but careful consideration is still required.

Single-storey extension design can really enhance a home but needs to be carried out sympathetically to the existing building.

If not, it could end up looking like a shoebox stuck on the back of a house as often happens if an architect is not involved.

Single-storey extensions need to consider features of the existing house and this can influence the form of the extension particularly where the roof adjoins the main building.

And there are many options when it comes to roof design: they can be flat-roofed, single-pitch lean-to, reverse lean-to or split-pitch – and there are many other possibilities too.

It is worth noting that current law allows for some single-storey extensions to be built without the need to obtain planning consent: this is called “deemed consent.”

These extensions must satisfy certain conditions in terms of size and height, and proximity to neighbouring boundaries.

But even without planning consent it is still recommended to obtain a lawful development certificate.

This takes the form of formal agreement from the local authority confirming that planning consent is not necessary.

This certificate may be requested by conveyancing solicitor when selling your property but is also something I can advise on.
