Loft Conversion

A loft conversion can be a great cost-effective way to add more space to your property. We have helped our clients create stunning loft conversions in all types of properties, with many different types of roof construction. Whatever the type of roof you have, we will have seen it before, and can provide you with all the advice and expertise that you will need.

Planning Permission:-

A loft conversion for your house is normally 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 additional roof space for terraced houses
∑ A volume allowance of 50 cubic metres additional roof space for detached and semi-detached houses
∑ No extension beyond the plane of the existing roof slope of the principal elevation that fronts the highway
∑ 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 original eaves.

Building Regulation Approval:-

Building regulations approval is a legal requirement required to convert a loft or attic into a liveable space.

The regulations will be applied to ensure, for example:

∑the structural strength of the new floor is sufficient
∑the stability of the structure (including the existing roof) is not endangered
∑safe escape from fire
∑safely designed stairs to the new floor
∑reasonable sound insulation between the conversion and the rooms below.

Our typical fee carry out the Structural Design only on a standard conversion without dormers would be £695

Typical work will involve:-

1. Design new floor joists.
2. Design any additional steel beams that may be required to support the floor joists.
3. Check adequacy of exisitng rafters, and redesign if necessary .
4. Design timber support for new windows.
5. Design overal roof stability, where additional steel beams may be required to support purlins and/or ridge.
6. Design splice joint connections to steel beams to facilitate access where required.
7. Check overal stability and capacity of existing structure to safely carry the additional loads from the new floor.
8. Calculations and drawings.
9. One site visit.
10. Liason with Building Control to ensure the project conforms to the legal requirements of Part A of the Building Regulations.

"Using a qualified Structural Engineer to design our loft extension meant that all the available options were clearly explained to us right at the start of the project, saving us both time and money" - Paul Heybyrne
