Loft Conversions London 

Welcome to MB Master Builders Ltd. - Bespoke Velux, Dormer and Mansard Loft Conversion Builders

Dormer, Mansard and Velux Loft Conversions are a great solution if you need to add extra space to your London Home and a regular house extension is not an option due to space constraint or planning regulation issues. We at MB Master Builders provide remarkable solutions for your loft conversion project. We aim to deliver premium quality results within the set deadline. Our team of professional loft conversion builders have years of experience in this line of work.

Interestingly, last year consumer magazine Which interviewed a number of householders who had recently had loft extensions built onto their homes. Around 76 per cent of individuals reported that they were delighted with their loft conversion. Those who weren’t wished they had asked for either more dormers, roof lights or windows. Others said they now see they should have spent more cash on fixtures and fittings in their new space while a handful said they wished their loft conversion was fully compliant so that they could describe it as a second bedroom.

We want all our clients to be one hundred per cent satisfied with their new living space. During our free estimate, we offer the benefit of our experience and advise you as to what are the best options available for you and your family when it comes to converting your loft space. 

Different Types of Loft Conversions

There are so many things to consider before starting your loft conversion project, such as the size, type and age of your property, the shape of your roof and of course, your household’s needs. So what are the main types of loft conversions out there and how will they transform the look of your home? 

Roof Ligh Conversion

With this popular type of loft conversion, you can remodel your attic into a bright living space. To get this done, our team of skilled loft conversion builders would need to reinforce the floors and add quality triple glazed roof windows, such as Velux, to the roof. 

Flat Roof Dormer 

This kind of transformation is prevalent among home-owners in London because it does not require a great deal of change. Our team will build a vertical wall from the slope of the existing roof. After that, a flat roof is constructed, giving the conversion a box-like shape.

Mansard Conversion

Mansard loft conversions are usually found at the rear of the property and are very popular in terraced houses. To build a mansard loft conversion, our team would alter the design of the roof by adding a horizontal edge and a 70 degrees inwards inclined wall.

Hip to Gable 

With this type of loft conversion, one side of the house (or both) are replaced with a gable wall. In order to achieve this, we would remove the sloped side of the roof and erect a triangular vertical wall, connecting the space between the central ridge and the new wall and tile it over.
