Main Contractor and Design and Build Contractor in London

Kisiel Group is a London main contractor for property developers. We build new homes, airspace extensions and conversions across London and the Home Counties, with our own piling company, Kisiel Piling, in the same group.

Because we are developers ourselves, we price and run your scheme the way we would run our own: buildable, on programme and on budget.

Call 0203 399 8226 or send us your drawings and tender package.

What we build for developers

Scheme type What we deliver Example
Ground-up new build Houses and apartment schemes on cleared, vacant or brownfield sites Executive town houses in West Wimbledon, GDV just under £9m
Airspace development New floors and apartments on top of existing buildings, built while the building stays in use Three projects in Bromley, 16 apartments in total
Conversions Redundant offices, industrial and commercial buildings converted to new use Sandiford Studios, Sutton

Our services

  • Main contracting on JCT contracts, including design and build
  • Pre-construction: feasibility studies, cost plans and value engineering
  • Planning support from our in-house planning team
  • Piling and foundations through Kisiel Piling
  • Groundworks, frame, envelope and fit-out
  • Modern Methods of Construction: Structural Insulated Panels (SIPs), Light Gauge Steel (LGS) framing and modular construction, using BOPAS-accredited systems

Why developers choose Kisiel Group

  • We think like a developer. We look at your appraisal, not just the drawings, and value-engineer the scheme to protect your margin.
  • Piling in-house. Kisiel Piling handles foundations, so there is no waiting on a separate specialist and no gap between packages.
  • Modern Methods of Construction. Off-site systems cut time on site and suit tight urban plots and airspace work.
  • Award-winning delivery. Housebuilder Award winner at the London Master Builder Awards 2025 and 2021, FMB London New Home Project and Large Renovation Project winner 2019, and Refurbishment of the Year 2018 and 2019.
  • Trusted by the public sector. Development partner with TfL on one of the first sites released under the GLA Small Sites programme.
  • A team that is growing. Our Graduate Programme was Highly Commended at the Construction News Workforce Awards.

How we work with you

  1. Early involvement. Bring us in at feasibility and we will flag cost, buildability and programme risks before planning is fixed.
  2. Clear price. A priced tender or cost plan with the assumptions spelled out.
  3. Programme. A realistic build programme agreed before we start.
  4. One point of contact. A named project manager from start to handover.
  5. Handover. Completed, snagged and documented.

Areas we cover

London and the Home Counties.

Frequently asked questions

What size of scheme do you take on?

From small infill and airspace schemes of a few homes up to apartment schemes of around 70 homes.

Can you help before planning is granted?

Yes. Early pre-construction advice is often where the biggest savings are made.

Do you only build, or can you also invest?

Both. On the right scheme we can work as a joint venture partner and put our own capital in alongside yours.
