About
Elevate the comfort and value of your home
At ABM Lofts, we specialise in transforming under-used roof spaces into beautifully designed, fully functional living areas that genuinely elevate the comfort and value of your home. With over 20 years of hands-on experience in loft conversions and house extensions across West Sussex, Surrey, and the Southeast, we bring deep expertise, thoughtful design, and trusted craftsmanship to every project we undertake.
From your first enquiry through to the final finishing touches, our approach is centred on quality, clarity, and collaboration. We know that choosing to extend or convert your home is a big decision – it’s about creating space that works for your family today and adds long-term value for tomorrow. That’s why we make the entire process as seamless and stress-free as possible.
What We Do
Loft Conversion Design & Planning
Your journey starts with thoughtful design. We take time to understand your goals, space requirements and aesthetic preferences. This includes:
- Detailed 2D and 3D design consultations
- Planning and building regulation guidance
- Options for dormer placements, Velux windows, and bespoke layouts
Getting the design right at the beginning saves time, avoids costly changes later, and ensures a stunning end result.
Full Build & Project Management
Once the design is agreed, our experienced team takes over the build with professionalism and efficiency. From erecting scaffolding, installing structural steels, and laying new floor joists to plumbing, electrics and internal finishes – we manage every stage with care and precision. We’re committed to delivering:
- Minimised disruption to your home life
- Quality materials and workmanship
- Clear communication throughout the build
Each project is handled by skilled professionals who meet current regulatory standards and building codes.

Whether you’re dreaming of a spacious new bedroom, a stylish home office, an inspiring playroom, or a luxurious master suite, we’re here to design and build a solution that fits both your lifestyle and your budget. We blend creative design with functional planning so that each conversion not only looks great, but feels right for the way you live.
