Where you can extend — and where you cannot

Extending a Notting Hill house starts with an honest question that does not arise in most of London: do you have a private rear garden, or does your house back onto one of the communal garden squares? Where the garden is communal, you generally cannot extend into it — it is shared, protected open space, not your land — so the options lie elsewhere.

Where there is a private rear garden or a side return, a single-storey extension can transform the ground floor. But Notting Hill is a conservation area, so permitted-development rights are restricted and any extension needs planning permission with a design that respects the rear elevation, the neighbours and the wider setting.

We tell you straight what your house can take, design an extension that is both useful and consentable, engineer the structure and the opening back into the house, and build it through to a finished room — one contract from drawings to handover.

What shapes a Notting Hill house extension

In Notting Hill, whether the garden is private or communal decides what is even possible.

01

Communal vs private

Houses backing onto communal gardens generally cannot extend into them; private gardens can.

02

Conservation restricts PD

In the conservation area, permitted-development rights are limited, so extensions need planning.

03

Neighbours count

Daylight, outlook and overlooking shape the depth and design of any rear extension.

04

Opening up

Connecting the extension to the house means a structural opening, engineered and party-walled.

Questions clients ask before they start

Can I extend into a communal garden?

Generally no — communal garden squares are shared, protected open space, not your land. If your house backs onto one, we look at other ways to gain space. We tell you honestly at the outset.

Do I need planning permission for an extension?

In the Notting Hill conservation area, almost always — permitted-development rights are restricted, so a rear or side-return extension needs a planning application.

What if I have a private rear garden?

Then a single-storey rear or side-return extension may well be possible, subject to conservation design and the neighbours. We assess and design it for consent.

Will my neighbours be involved?

Extending and opening up the rear on a terrace engages the Party Wall etc. Act 1996. We manage the notices and awards.

What does a house extension cost?

It depends on size, structure and finish. We give an honest budget band in pounds sterling (GBP) after a feasibility visit.
