How can we help?

Dormer Conversion

One of the most popular loft conversions across the Bromley borough, a dormer loft conversion uses a vertical roof extension to create additional headroom within the property. One of the additional benefits of building such a loft 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 ensure everything is just the way you wanted it to be.

L-Shaped Dormer Conversion

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. Depending on the size of your Bromley 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.

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 loft conversion is best suited to bungalows, detached or semi-detached properties – and is a great choice for customers with 1930s properties – good news for Bromley residents where this housing style prevails. 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.

Mansard Conversion

A highly individual looking loft conversion, a Mansard loft conversion is usually constructed to the rear of the property. Offering a stylish, flat-roof option, this type of loft conversion has been growing in popularity across urban areas over recent years. Named after 17th-century French architect Francois Mansard, a Mansard loft 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, quality comes as standard, which is why we only fit industry-leading Velux Windows in our loft conversions. Not only that, but LMB Group is one of the area’s 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.
