When considering a loft conversion, be assured that we can offer advice and assistance into what type of conversion is best for you, your home and still meets all necessary requirements.

There are different variations of loft conversions, but the most common are:

Roofline loft conversions:

Where we would create the space within the existing shape of the roof, adding roof windows for light and ventilation.

Dormer loft conversions: 

Where an extension of the roof would be created.

Hipped to Gable loft conversions:

Where the hipped part of the roof would be replaced with a vertical gable end.

We offer the full loft conversion package!

Depending on the type of conversion best for you, it may be that planning permission is required. Not to worry! LSM Builders offer a complete design and build service tailored to your specific needs, requirements, budget and taste.
