What A Loft Conversion Project Covers
Every loft conversion managed by Mr Construction Building Ltd includes the structural alterations, roof modification, floor installation, staircase, insulation, electrics, plumbing where the new room requires it, and the full internal finish. Every element is carried out by the same team, with no separate contractors to source or coordinate at each stage of the build. The project scope and cost are agreed in full before work begins, and that agreement holds unless the client requests a change to the specification once the conversion is already underway on site.
Planning And Building Regs For London Loft Conversions
A loft conversion in London requires either building regulations approval or, in some cases, full planning permission, depending on the conversion type and the property itself. Mr Construction Building Ltd manages the correct submission route before any work begins, and all construction is carried out to the standard required for approval throughout the project. Completion certificates are issued once the project has been inspected and signed off, so the documentation is already in place for a future sale or mortgage application without retrospective action needed from the homeowner at a later date.


Loft Conversions Delivered On Time Across London
Customers who have used Mr Construction Building Ltd for loft conversions across London have noted the projects were completed within the agreed timeframe and finished to the standard set out at the quote stage. The team has delivered loft conversions across terraced, semi-detached, and detached properties in West and Greater London for more than 30 years, across a wide range of roof types. Every build is backed by public liability and employee insurance, in place throughout the construction period and not removed before practical completion of the finished room.
"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."
Loft Conversions Across West And Greater London
Loft conversion work spans West and Greater London, with concentrated experience in Ealing, Acton, Chiswick, and Brentford where roof types and conservation status vary noticeably between the four areas. A dormer conversion straightforward in one borough may need full planning permission in another, and this is established before any design work begins rather than after submission. Properties outside these areas are taken on too, with roof structure and the correct approval route confirmed during the initial site visit ahead of any quote being issued to the homeowner.
