About Us
A building team you can hand the keys to
Atas4b Construction UK Ltd delivers construction, renovation, extensions and general building work across the UK — priced honestly, planned properly and finished when we said it would be.

Company introduction
Built on repeat clients and referred work
We are a UK building contractor working across London, the South East and the Midlands, and taking on larger projects UK wide. Our work ranges from a single repaired wall to a complete renovation of an occupied home.
The company was set up on a simple idea: most building complaints are not about the workmanship, they are about the communication. So we quote properly, we show up when we said we would, and we tell you the moment something changes.
How we work
Mission, values and safety standards
Mission

- Public liability and employers' liability insurance held
- Dust sheets, edge protection and clear access routes maintained
- Sites cleared and made safe at the end of every working day
- Waste removed and recycled where facilities allow
Why choose us
Five reasons clients come back
One team from survey to snagging
The person who measures up and prices the job is the person running the site. Nothing gets lost between departments.
Fixed prices, not estimates that drift
You get a written schedule of works with a total that does not quietly grow once the first floor is pulled up.
A programme you can hold us to
Start dates, key stages and completion are agreed up front, and reported on weekly with photographs.
We deal with building control
Drawings, notifications, structural calculations and inspections are arranged and chased for you.
Existing clients get priority
General building works and call-outs are slotted in quickly for people already on our books.
Experience
We know our trade
Our team spent their working lives on UK building sites. We work on Victorian and Edwardian terraces, post-war semis, modern new builds, listed buildings where consent applies, and commercial units that have to keep trading.
That range matters on site. Most building problems have been met before by someone who knows what actually fixes them, and a team at home in older stock can usually tell you what a new-build plot will throw at it, and vice versa.
On every project
Run under the direction of a construction engineer
Every project we take on, large or small, is planned and supervised under the management of a specialist construction engineer. Surveys, specifications, structural decisions and the final sign-off sit with that engineer — not with whoever happens to be on site that day.
It is the difference between work that looks finished and a job that is built, checked and signed off properly.
