Unique loft conversions and trusted VELUX installation


At Unique Build, we make custom lofts. No off the shelf solutions. No pre-packaged loft designs. No saying ‘no’. We build bespoke to your home and you.

Being ‘Unique’ reflects upon both the work we do and the approach we take. The spaces we create are unique, but so is the way we handle every project.

We view each project as a unique home–your home, and we build a loft based on your ideas and dreams. That’s why we don’t do ‘off-the-shelf’ loft solutions, and we’ll tailor our work to fit what you want.

We always go above and beyond in our work, but our prices remain extremely competitive. Despite our tailored approach, our quotes might just surprise you. If you’re ready to build a truly bespoke and custom loft, then get in touch. Your home deserves nothing less.


We will complete VELUX installations as part of our loft conversions, but we also offer VELUX services outside of our loft work.

We are a VELUX Certified Installer – the highest accreditation available, and a stamp of approval from VELUX themselves. In short, there’s no one they trust more highly with their windows.

We offer VELUX installation services to help you breathe new life into your home with VELUX windows.

You may also need replacements and repairs on VELUX windows that you already have. All of our VELUX work comes with 10 year guarantees.
