Oxford builders dedicated to loft conversions and thoughtful home extensions
Founded by tradespeople who grew up around Oxford's period housing stock, we've spent years turning cramped homes into properties that actually work for the people living in them.
Get a QuoteWhat Homeowners Say About Working With Us
We needed an extra bedroom and a proper office, not just a boxed-in attic. The team walked us through the structural options before we signed anything, and the loft was done in eleven weeks with barely any dust in the rest of the house.
Our kitchen extension involved knocking through to a listed-adjacent wall, which made the planning stage a headache with the council. La Garantie Avie handled the drawings and back-and-forth themselves, so we just had to approve things.
I run a small tutoring business from home and needed a quiet garden room built off the existing extension. They gave me a fixed price upfront and stuck to it, even after we changed the window layout halfway through.
Who We Build For
Most of our clients are Oxford homeowners who've outgrown their current layout
Parents needing an extra bedroom, playroom, or bathroom without the disruption and cost of moving house across Oxford.
Owners of Victorian and Edwardian terraces who want more space while keeping the character of their original building intact.
Property owners converting unused loft space into a lettable room to increase rental income or resale value.
Homeowners who need a dedicated office or studio separated from the main living areas of the house.
What Sets Us Apart
Built on years of working within Oxford's specific planning and building requirements
We regularly work with Oxford City Council's planning department and understand what conversions typically get approved in conservation areas.
You deal with the same project manager from the first site visit through to final sign-off, not a rotating cast of subcontractors.
Our quotes are itemised and fixed before work starts, so you know the cost of materials, labour, and any structural work upfront.
Carpentry, plastering, and electrical work are handled by our own team, which keeps scheduling tight and reduces handover delays.
