What Your Extension Project Includes
A house extension with Mr Construction Building Ltd covers everything from planning and structural design through to the finished interior. The team handles groundworks, brickwork, roofing, windows and all internal trades in house, so there is no need to source and manage separate contractors for each stage of the build. Every extension starts with a detailed survey and a fixed cost quote so both sides are clear on scope before any work begins, and that cost does not change unless the scope does, giving homeowners certainty on budget from the outset of the project.
Design That Matches Your Property From Day One
When the team designing an extension is also the team building it, the finished result stays consistent with what was agreed at the outset. Mr Construction Building Ltd carries out design and construction in house, which means the structural constraints and planning requirements of the property are considered during the design stage rather than discovered during the build itself. Whether the project is a rear extension, a side return, or a two storey addition, the design is produced to match the existing architecture and the budget agreed at the survey, with no surprises later.


Fully Insured And Compliant Across London
All extensions carried out by Mr Construction Building Ltd comply with current building regulations, with completion certificates supplied once the work has been signed off by building control. Public liability and employee insurance is in place throughout every project, covering both the homeowner and the property for the duration of the build. The team is based in Ealing and works across West and Greater London, and has delivered house extensions across a range of property types over more than 30 years in the construction industry, from period terraces to modern detached homes.
"Mr-Construction are a rare find. Honest, very skilled builders who take pride in delivering great quality work. The extension and the loft they built for us look great. And the work was done on time. They were prepared to listen to us, were polite and accommodating. Thank you guys, very happy customers here."
House Extensions Across West London
Extension projects are carried out across London, with the bulk of recent work concentrated in Ealing, Acton, Chiswick, and Brentford. Conservation area restrictions vary significantly between these boroughs, and the team factors this into every design from the first survey rather than discovering it part way through planning. Properties outside these core areas are also taken on, subject to a site visit confirming access and scope. Getting an accurate sense of what your specific borough allows is usually the first conversation worth having before any design work starts.
