Loft Conversion London

If you are looking for a loft conversion company in London, look no further. The past few years have seen a surge in loft conversions and extensions across London, as property owners are finding that not only is it a more cost-effective option, but it adds value to a property.

Types of Loft conversions

The SDA Build London team will work closely with either your or our architects and interior designers to ensure that you get the loft conversion that is most suited to your property as there are several different types, including dormer loft conversions, mansard loft conversions, hip to gable loft conversions, and roof light loft conversions.

The kind of loft conversion you choose will depend on a number of factors including council planning and permitted development rules, the slope, shape and pitch of your roof and of course your budget. Your loft

conversion architect should be able to advise you on the best way forward and the most suitable loft conversion or extension for your home.

Costs of loft conversions

Typically, loft conversions can cost anywhere between £20,000 to £60,000 depending on the internal specs you choose. The average dormer loft conversion with a double bedroom and en-suite may start at around £35,000– £45,000.

If you decide you want to increase the roof height or change the overall structure by removing the existing roof and redesigning the overall look and structure, the cost will increase significantly and start at around £45,000.

At SDA Build London, we offer a full-service loft conversion or extension. With our team, there is no compromise on quality, reliability, safety and making sure that we abide by all building regulations and permissions.
