Velux Conversions, Dormer and Mansard Extension Builders

Velux loft conversions in North London

Roof Lights Attic Conversions


If you have an unused attic space where more than half of the floor area has the 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 in your home.

Often called Velux conversions, 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 conversions 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 attic. A spiral staircase is an excellent solution if you feel that a standard staircase would take up too much of the loft space. Customers satisfaction is our priority, which is why our loft conversion company in North London gives a ten-year structural warranty.

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

Dormer loft conversions North West London

Dormer and Mansard Loft Extensions


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

With these types of loft conversions 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 are the more expensive attic conversions and require more external and internal refurbishment than Velux conversions, they will give you more headspace and design freedom. If you are unsure which type of conversion or extension is right for your family or your property. Our highly recommended loft conversions in North London experts will provide you with the best attic advice possible.

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