About Nabcon
BUILDING LONDON HOMES SINCE DAY ONE
A London-based construction company built on trust, driven by excellence — and by the people who show up on site every day.
Our Story
FROM LOCAL TRADESMEN TO A TRUSTED LONDON BUILDER
Nabcon Construction was founded in East London with a simple aim: deliver construction work homeowners can actually rely on — fair pricing, honest timelines, and a finish that lasts.
Over 15+ years we've grown from small residential jobs into a full-service contractor covering loft conversions, rear extensions, renovations and new builds across London and the surrounding areas, without losing the close, hands-on approach we started with.
Every project is still run the same way: a proper site survey, a transparent quotation, and a dedicated point of contact from the first phone call to the final handover.
What We Stand For
OUR CORE VALUES
Honesty
Straight answers on cost, timeline and what's actually achievable.
Precision
Detailed drawings and careful workmanship at every stage.
Respect
For your home, your family, and your neighbours throughout the build.
Craftsmanship
Skilled trades who take pride in getting the details right.
How We Operate
OPERATIONAL HERITAGE & STANDARDS
Every project runs on the same disciplined standards, regardless of size — here's what that means in practice.
London Coverage & Operational Heritage
Nabcon Construction has operated across East London and the surrounding boroughs for 15+ years, building a reputation project by project rather than through advertising alone. We cover Barking, Dagenham, Chadwell Heath, Ilford, Romford, Chigwell, Wanstead and the wider London area, with a permanent office base in Chadwell Heath. Browse our completed loft conversion and extension projects across these areas.
Our growth has been organic — the majority of new work comes from referrals and repeat clients, which keeps us accountable to the same standard on every job, not just the ones being watched most closely.
Quality Assurance & Structural Guarantees
Every structural element — beams, foundations, load-bearing changes — is specified by a qualified structural engineer and checked against building control requirements before work begins on site. We don't treat calculations as a formality; they're the basis the rest of the build sits on.
- Structural work backed by engineer's calculations and sign-off
- Workmanship guarantee on completed projects
- Materials sourced from accredited UK suppliers
Safety Policies & Building Regulations Compliance
Health and safety isn't an afterthought on our sites. Every project begins with a documented risk assessment and method statement, and site teams follow CDM 2015 regulations throughout. Building control is engaged from the design stage, not brought in retrospectively — full plans or a building notice are submitted before groundworks start, with inspections carried out at each mandated stage.
- Risk assessments and method statements on every site
- CDM 2015 compliant site management
- Building control involved from design through to completion certificate
Client Communication & Project Management
You get a single point of contact for the life of your project — not a rotating cast of subcontractors you have to chase for updates. Progress is communicated on a set schedule, and any changes to cost or programme are agreed in writing before work continues, so there are no surprises at the final invoice.
A fixed, itemised quotation is provided before any contract is signed, and a project programme sets out key milestones so you always know what stage the build is at and what's coming next. Ready to start? Get a free quote for your London loft conversion, extension or renovation.
