The division
LINX Design & Build is where the group began. Founded in London in 2017, it has grown into a team with more than 30 years of combined experience, delivering extensions, loft conversions, renovations and new builds for homeowners, landlords, developers and public sector clients.
Every project runs through one team. Our in-house architects prepare the drawings and take them through planning and building regulations, and the same company builds what was drawn — with 60+ tradespeople employed directly rather than a chain of subcontractors.
That is what makes the price dependable: a fixed figure in writing, a JCT contract, a dedicated project manager and site foreman, and a 10-year structural guarantee when the work is done.


Services
LINX Design & Build works for private clients and the public sector alike, with the same team, the same standards and a fixed price in writing.
Premium residential construction services delivering luxury new builds, extensions, and complete refurbishments with exceptional quality and craftsmanship.
Comprehensive construction and refurbishment services for public sector projects including schools, community centres, and public housing.
We provide comprehensive design & build services tailored to meet the unique needs of the public sector, ensuring compliance, quality, and value for communities.

Questions
One company is responsible for the whole project: survey, architectural drawings, planning, structural engineering and building regulations, then the build and the handover. You have one contract and one point of contact instead of managing an architect and a builder separately.
Yes. Our Build Only service starts from your architectural and structural drawings. We survey the site, review the drawings and send a detailed construction quotation, normally within 1–5 working days once we have enough information.
Yes. You receive a fixed-price quotation in writing before work starts, with no provisional sums that move once the build begins. Every contract carries our 10-year structural guarantee.
Across London and the South East, including Surrey, Kent, Berkshire and Essex. The first consultation is free, wherever the project is.
