Bespoke House Extensions
Increasing the size of your home not only gives you more space, it can also add
value to the property.
As well as converting lofts, many homeowners are choosing to build an extension
rather than moving house. House extensions are an affordable and cost effective
option to upgrade your home, adding extra space for a new
kitchen, office space, an additional reception room or playroom.
House extensions have become so popular that we have dedicated a team of craftsmen
specifically for extension work. Our team is highly professional, but also friendly
and open to questions. If you’re not sure about something, just ask!
Bespoke House Extension Design
We will work with you to design and build your perfect extension, constructed to
your specifications and custom designed to fit the shape and style of your property.
We use professional and reputable architects to draw up your extension designs,
ensuring that the finished extension not only looks good but that the work is completed
to meet with the required building regulations.
Planning Permission for House Extensions
Under new regulations that came into effect on 1 October 2008 an extension
or addition to your house is considered to be permitted development, not requiring
an application for planning permission, subject to the following limits and
conditions:
- No more than half the area of land around the "original house"* would
be covered by additions or other buildings.
- No extension forward of the principal elevation or side elevation fronting a highway.
- No extension to be higher than the highest part of the roof.
- Maximum depth of a single-storey rear extension of three metres beyond the rear
wall for an attached house and four metres beyond the rear wall for a detached house.
- Maximum height of a single-storey rear extension of four metres.
- Maximum depth of a rear extension of more than one storey of three metres beyond
the rear wall including ground floor.
- Maximum eaves height of an extension within two metres of the boundary of three
metres.
- Maximum eaves and ridge height of extension no higher than existing house.
- Side extensions to be single storey with maximum height of four metres and width
no more than half that of the original house.
- Two-storey house extensions no closer
than seven metres to rear boundary.
- Roof pitch of extensions higher than one storey to match existing house.
- Materials to be similar in appearance to the existing house.
- No verandas, balconies or raised platforms.
- Upper-floor, side-facing windows to be obscure-glazed; any opening to be 1.7m above
the floor.
- On designated land* no permitted development for rear extensions of more than one
storey.
- On designated land no cladding of the exterior.
- On designated land no side extensions.
* The term "original house" means the house as it was first built or as
it stood on 1 July 1948 (if it was built before that date). Although you may not
have built an extension to the house, a previous owner may have done so.
* Designated land includes national parks and the Broads, Areas of Outstanding Natural
Beauty, conservation areas and World Heritage Sites.
Building Regulations
Most extensions of properties require approval under the Building Regulations.
Our team of builders has a great deal of experience building house extensions, particularly
in and around London. We are very familiar with the stringent rules and regulations
required with planning permission applications and of working with a number of different
local authorities.
Combining your ideas with our knowledge and understanding of the planning requirements
in your area, we can invariably eliminate any planning problems that may occur before
the final plans for your extension are drawn and submitted. Pricing House Extensions
When calculating the cost of building your house extension, it is important to consider
the size of the proposed extension, as well as other factors such as the presence
of underground drains, slopes, the foundation depth needed to prevent future subsidence
and local planning considerations.
Due to the many varying factors that can affect house extension costs, Bespoke House
Extensions prefers not to fix prices without an initial inspection of the property
and site as well as investigating specific planning restrictions. This enables us
to keep your costs down, work to your budget and to ensure that your new extension
is exactly what you want.
We provide a fully itemised quotation for all house extensions that takes into account
the cost of the architect’s initial designs to completion of works that meet
Building Control standards.
