Why Loftus Design and Build?

Whether it’s a loft conversion or back extension you’re thinking of, you’ve come to the right place. There are a number of reasons why you should consider us to help you realise your dream build.

Notably, we like nothing more than helping homeowners and their families not only get their dream loft or extension, but also to enjoy the experience. And it’s desire that led to the development of our unique off-site build system.

Loft conversions and back extensions in 4 weeks or less?


The Loftus ProFastBuild Modular Off-Site Loft Conversions and House Extensions Construction System™ .

Our proven ‘off-site’ loft construction system involves approximately 80% of the whole build and the 20% is the install and finishing.

Therefore 80% of the dust, rubbish and noise are in our dedicated workshop and not in your home.
