Mars Building Ltd - Loft Conversions
Under new regulations that came into effect from 1 October 2008 a loft conversion is increasingly becoming the most popular way to add the extra space you need in your home, whilst adding value at the same time.
Mars Building Ltd are able to offer a full Loft Conversion service, from an initial no obligation consultation to designing with our architect and then project management and construction of your loft from start to finish.
Planning permission is not normally required. However, permission is required where you extend or alter the roof space and it exceeds specified limits and conditions.
Under new regulations that came into effect from 1 October 2008 a loft conversion for your home is considered to be permitted development, not requiring an application for planning permission, subject to the following limits and conditions:
A volume allowance of 40 cubic metres for terraced houses.
A volume allowance of 50 cubic metres for detached and semi-detached houses.
No extension to be higher than the highest part of the roof.
Materials to be similar in appearance to the existing house.
No verandas, balconies or raised platforms.
Side-facing windows to be obscure-glazed; any opening to be 1.7m above the floor.
Roof extensions not to be permitted development in designated areas*.
Roof extensions, apart from hip to gable ones, to be set back, as far as practicable, at least 20cm from the eaves.
