How can we help?

Dormer Conversion

As the most common form of loft conversion, a dormer conversion uses a vertical roof extension to create additional headroom within the property and remains one of the most popular conversion styles for Wimbledon-based homes. 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

You may wonder whether, if you live in a smaller home that a loft conversion may not be possible. But the L-shaped dormer conversion is ideal for mid-terraced houses as it combines two dormer extensions which join together to form an L-shape. Depending on the size of your Wimbledon property, an L-shaped dormer can add anything between 20sqm-50sqm, giving a great deal of extra floor space as well as plenty of eaves storage.

Hip-to-Gable Conversion

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 – good news for Wimbledon residents where this style of house is widely available. A hip-to-gable conversion involves replacing the sloping part of your roof (the hip) with a vertical wall (the gable). 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

A highly individual looking loft conversion, a Mansard conversion is situated to the rear of the property and offers a stylish, flat-roof option, this type of conversion has been growing in popularity across urban areas over recent years – again good news for our Wimbledon-based customers. 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

At LMB Group, excellence comes as standard, which is why we only work with only the finest names such as brand-leading Velux - we are also proud to say we are one of the area’s few accredited and approved Velux window and blind installers.
