Loft Conversions

Thinking of moving because you need extra space? The extra space needed for you and your family is already in your home, ever considered having a Loft Conversion? You can seamlessly and cost-effectively extend your living space by converting your loft or attic, adding value to your home.

Our conversion plans are as individual as your home. We cater for your needs and budget to create that extra living space - bedroom, bathroom, office, or simply somewhere to relax.

There are two basic types of loft conversions - a "roofline" conversion, and a "dormer" conversion with many variations of the latter.

Roofline loft conversions
With this type of conversion, we can create a room/rooms within the existing shape of the roof, using Velux windows for light and ventilation. With this type of conversion, we would not extend or alter the existing shape of the roof at present.

Normally, planning permission is not required for this type of conversion. However, a full set of Architect's plans would be necessary along with the designs of a Structural Engineer and subsequent calculations to verify designs. This will be necessary to justify all current building regulations.

Dormer loft conversions
A Dormer loft conversion extends out from the existing roof shape. Most typical roof shapes do not usually have enough available space to allow a substantial habitable room, unless the house is unusually large. So with this type of roof structure, it would be advisable to extend the roof and create a Dormer (usually to the rear of the property.)

The size, shape and general design of this or any other Dormer can vary greatly. This type of conversion may also not require planning permission. Householders have what is known as a permitted development allowance. This permitted development allowance is usually measured in cubic metres. The amount allowed (cubic metres) varies from property to property. Generally, the allowance would be between 50 and 70 cubic metres or 20% of the overall volume of the property.

We can survey your property to calculate the required volume for any dormer and whether or not this would fall within permitted development rights. Please note, there are further guidelines whilst trying to identify if your project would be allowed under permitted development rights. These are;

No part of the new structure must rise any higher than the existing highest part of the roof at present (usually the ridge line.)
Looking down on a plan, no part of this new structure must exceed the current floor plan boundary.
The property must not be in a conservation area.
As with roof line conversions, even if planning permission is not required, it is necessary to conform and to comply with the current building regulations.
