How can we help?

Dormer Conversion

As the most straightforward type of loft conversion, a dormer conversion uses a vertical roof extension to create additional headroom within the property. It has remained one of the most popular conversion styles for Dulwich-based homes for a number of years. An additional benefit of building such a conversion is that it does not necessarily require planning permission. At LMB Group our trusted team will help you work out all aspects of the build, before, during and after to make sure everything is just the way you wanted it to be.

L-Shaped Dormer Conversion

If you live in a smaller house you may wonder whether a loft conversion will be possible. Well, relax – at LMB Group we provide a range of solutions such as the L-shaped dormer conversion which is ideal for mid-terraced houses. Depending on the size of your Dulwich property, an L-shaped dormer (which combines two dormer extensions that join together to form an L-shape) can add anything between 20sqm-50sqm, giving a valuable amount of floor space as well as plenty of eaves storage.

Hip-to-Gable Conversion

A hip-to-gable conversion involves replacing the sloping part of your roof (the hip) with a vertical wall (the gable). A hip-to-gable conversion is a great option for bungalows, detached or semi-detached properties – and is an ideal fit for customers with 1930s properties. To provide maximum efficiency and floor space, we can build a double hip-to-gable conversion, or even combine it with a dormer conversion at the rear of your property.

Mansard Conversion

This type of conversion has been growing in popularity across urban areas over recent years. A highly individual looking loft conversion, a Mansard conversion is situated to the rear of the property and offers a stylish, flat-roof option. Named after 17th-century French architect Francois Mansard, a Mansard conversion offers peak space but almost always requires planning permission from the local authority and is at the higher end of the loft conversion pricing spectrum.

Velux Windows

Excellence comes as standard at LMB Group, and we work with only the finest materials and biggest names in the construction industry such as brand-leading Velux.
