Builders in London: extensions, lofts, refurbishments and structural work by one team

Ask for documents before prices. A written specification that names materials and standards, so quotations can be compared line by line. The insurance schedule. The name of the person who will be on site and how often, and who manages the trades. Who handles building control and party wall notices. Then look at completed work with your own eyes and speak to a previous client about whether the date and the price held. Directories and review sites are a starting point, not a check.

A specification, not just a sum. Each element of the work described and priced, the materials and standards named, the exclusions listed, and anything genuinely unknowable stated as a provisional sum so you can see which part of the figure is firm. It should say who applies for building control, who serves party wall notices, what happens to variations, and how payment is staged. A one-page quotation with one number is not cheaper; it is less defined, and the difference appears later.

Both, honestly described. MO Team Construction Ltd was incorporated in June 2025; Mo has been building since 2017. There is one team and one site manager, which sets the size of job we take on: single-property residential work, structural packages and commercial fit-outs. Because the same team fits out shops for brands to a landlord's programme, it is used to permits, dates and clean handovers, which homeowners benefit from more than they expect.

Yes, where they are whole jobs: a bathroom, a structural opening with a steel, a section of failed render, a garden room with power, a drainage repair. What we are not set up for is a single trade on someone else's programme, or a two-hour repair, because the same person who runs the site has to be there and it is not fair to price that in. If a job is too small for us we will usually say so and suggest what kind of tradesperson to ask instead.

We are one team with one site manager, which sets a natural ceiling. Single-property residential construction, extensions, loft conversions, full refurbishments, structural work, rendering and groundworks packages, and commercial fit-outs of a unit at a time are the right size. A multi-unit development or a project needing several crews on site at once is not, and we would rather say so at the first conversation than take it on and run it thinly.

Regularly. Where the design is settled we price and build to the architect's drawings and specification, attend design team meetings, and raise buildability issues in writing rather than solving them silently on site. If you do not have one yet, we will tell you at the first visit whether the job needs one, and an architect's involvement is often the right call on a conservation area house or a larger extension.

Yes, all three, and they are in our projects section. Groundworks covers excavation, foundations, slabs, drainage, soakaways and retaining structures, which is where most surprises on a site live. Rendering covers stripping failed render, repairing the substrate and specifying a system suited to the wall, with the beads and movement joints that decide whether it cracks again. Structural work covers steels, openings, chimney breasts, underpinning and basements, with an engineer's design and building control inspection.

Often not, if it stays within the permitted development limits for outbuildings: single storey, height limits that tighten within two metres of a boundary, no more than half the garden covered, and no use as sleeping accommodation. Those rights are reduced in conservation areas, on listed properties and where an Article 4 direction applies, and they do not exist for flats (Planning Portal, outbuildings, checked September 2026). We confirm the position with your borough for the address before pricing, and a certificate is worth having before you sell.

Yes. We act as principal contractor on projects involving more than one contractor and prepare a construction phase plan before work starts. The documents you receive at handover are set out on our accreditations page. We do not list schemes or logos we do not hold.

We are based in London and build across it, north and south of the river, with the residential work concentrated where the houses are: the Victorian and Edwardian terraces and the 1930s semis of the inner and outer boroughs. The areas page lists the boroughs with a page of their own. For brand rollouts the crew travels, which is how we came to fit out stores in Manchester, Liverpool and Oxford, but a one-off house project outside London is usually better served by someone local.
