Loft Conversion Specialists North London

Velux Conversions, Dormer and Mansard Extension Builders

Extending your loft could be the perfect solution if you need to add an extra room to your London home, and a single or double-storey extension is not an option due to planning restrictions or the garden space not being sufficient. Our experienced team can turn your unused attic into an extra bedroom with clever storage-saving solutions such as a fitted wardrobe or a staircase that can double as a chest of drawers. Years of experience in this field of work mean that we can advise you on what type of attic conversion or loft extension project will be the best option for you. We work under fully insured conditions, and all our work comes with a ten-year structural warranty.

Roof Lights Attic Conversions

If you have an unused attic where more than half of the floor space has a floor to ceiling height of at least 2.1 metres, you could easily turn this room into 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 conversion is the most affordable and fastest to complete. Our experienced team would need to reinforce the attic floor, remodel the roof by inserting at least two Velux or other high-quality roof windows, and build stairs which will usually have to be placed in the centre of the loft. A spiral staircase is a simple and economical solution if traditional stairs won't fit.

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 renovation projects, the back or the front of the roof would be raised 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 these type of loft extensions are more expensive and take longer than a Velux conversion, they will give you more headspace as well as design freedom as you can choose where the stairs will go.

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