At Abhi Builders, we specialise in designing and building high-quality loft conversions that transform unused roof space into beautiful, functional living areas — adding significant value to your home. Whether you need a dormer, hip-to-gable, mansard, or Velux conversion, our experienced team handles every aspect from planning to handover. Serving West London including Hayes, Southall, Harrow, Slough and surrounding areas.
With over 10 years in the industry, we manage planning applications, structural work, and all trades in-house — delivering seamless, stress-free loft conversions on time and on budget.
From simple Velux conversions to full mansard builds, we cover every type of loft conversion.
The most popular conversion type — a flat-roofed extension projecting from the roof slope to create a full-height room.
A cost-effective option that keeps the existing roof structure and adds roof windows to flood the space with light.
Ideal for semi-detached and detached homes — the sloping hip end is replaced with a vertical gable wall for maximum space.
A full structural conversion that alters the roof shape entirely, delivering the maximum possible loft living space.
Transform your loft into a stunning master bedroom suite complete with en-suite bathroom and built-in storage.
Full structural engineering, steel beam installation, and bespoke staircase design carried out to the highest standard.
Based in North Harrow, we have spent over a decade converting lofts across West London. We understand local planning rules, building regulations, and roof structures in the area.
We handle permitted development assessments and full planning applications, ensuring your loft conversion meets all building regulation requirements from day one.
We provide detailed, honest quotes with no hidden costs. Our pricing is designed to suit a range of budgets without ever compromising on quality.
No need to manage multiple contractors. Our in-house team covers structural work, carpentry, plumbing, electrics, tiling, and decorating under one roof.
We plan carefully and work efficiently, keeping disruption to your daily life to a minimum and keeping you informed at every stage so there are no surprises.
Every loft conversion we build comes with a full workmanship guarantee. If anything isn't right, we come back and fix it — simple as that.
