How can we help?

Dormer Conversion

A dormer loft conversion uses a vertical roof extension to create additional headroom within the property and remains one of the most popular loft conversions across the Croydon area. 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 negotiate 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

Depending on the size of your Croydon home, 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. In our experience, the L-shaped dormer conversion is often the best choice for mid-terraced houses. It uses two dormer extensions which join together to form an L-shape.

Hip-to-Gable Conversion

A hip-to-gable conversion comprises replacing the sloping part of your roof (the hip) with a vertical wall (the gable). To provide maximum effectiveness and space, you can create a double hip-to-gable conversion, or even combine it with a dormer conversion at the rear. A hip-to-gable conversion is best suited to bungalows, detached or semi-detached properties – and is a great choice for customers with 1930s properties – good news for Croydon residents where this style is popular across more suburban parts of the borough.

Mansard Conversion

Offering 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 Croydon-based customers. A highly individual looking loft conversion, a Mansard conversion is situated to the rear of the property. 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 fit industry-leading Velux Windows in our loft conversions, and we are proud to say we are one of the area’s few accredited and approved Velux window and blind installers. Over the years these stylish, well-made windows have become the first choice when it comes to providing your new loft conversion with natural light. Velux come in a range of designs and shapes and can be individually crafted to suit your specific loft conversion.
