How to Extend a Property
With Stamp Duty at 3% for properties worth more than £250,000, estate agent fees usually between 1% and 2% of a sale price, and removals and decorating costs as long as the proverbial piece of string, it is easy to see why many home owners are turning to extensions as a way of increasing space and value to their property.

3 No extension can be higher than the highest part of the roof.
4 A single-storey rear extension must not extend beyond the rear wall of the original house by more than three metres, if an attached house, or by four metres, if a detached house.
5 The maximum height of a single-storey rear extension is four metres.
6 Extensions of more than one storey must not extend beyond the rear wall of the original house by more than three metres.
7 The maximum eaves height of an extension within two metres of the boundary is three metres.
8 The maximum eaves and ridge height of an extension is to be no higher than the existing house.
9 Side extensions are to be single storey with a maximum height of four metres and a width of no more than half that of the original house.
10 Two-storey extensions can be no closer than seven metres to the rear boundary.
11 The roof pitch of extensions higher than one storey have to match the existing house.
12 Materials are to be similar in appearance to those used on the existing house.
13 No verandas, balconies or raised platforms are allowed.
14 On the upper-floor, side-facing windows have to be obscure-glazed and any opening needs to be 1.7m above the floor.
15 On designated land - no permitted development for rear extensions of more than one storey.
16 On designated land - no cladding of the exterior.
17 On designated land - no side extensions.
Depending on local plans and regulations, planning departments can be open to imaginative ideas. The examples above include a full height glass extension and an 18th century top floor addition to a farmhouse.
