This will add even more living space and value to your house. Years of experience in this field of work means that we can advise you on every aspect of your London loft project. We work under fully insured conditions, and all our work comes with a ten-year structural warranty and one year of repair service.

Velux loft conversions North London

Roof Lights Attic Conversions

If you have an unused attic space where more than half of the floor area has floor to ceiling height of at least 2.1 metres, you could be just a few steps away from building a roof light loft conversion.

Often called a Velux conversion since this brand of windows is commonly used in this type of home improvement project, this loft conversion design is the most affordable as it does not require a large amount of building work. Our North London loft conversion team would start the process by reinforcing the attic floor followed by the installation of two or four Velux or other high-quality roof windows. Our builder or joiner would then build stairs in the centre of the loft. A spiral staircase is an excellent solution if you feel that a standard staircase would take up too much of the loft space. Customer satisfaction is our priority, which is why our loft conversion services come with a ten-year structural warranty.

Because the shape of the roof does not change, roof light conversions do not require planning permission.

Dormer and Mansard Loft Extensions

If your loft does not have sufficient head height, a mansard extension or a flat roof dormer could be the perfect solution if you need to add and an extra bedroom with an ensuite to your home.

With these types of loft conversion designs, the roof structure is altered by raising the back or the front of the roof to create more ceiling space. Dormers are added to a sloping roof at 90 degrees with vertical sides and a flat roof, while mansard extensions raise from the edge of the roof at around 70 degrees. While dormer and mansard conversions are more expensive and require more external and internal refurbishment than a Velux conversion, they will give you more headspace and design freedom. If you are not sure which type of conversion or extension is right for your family or your property, our highly recommended loft conversion experts will provide you with the best loft advice possible.

You might not need planning permission for a rear dormer. Front dormer and mansard extensions will require approval from the local authority.
