Planning a project
Most commonExtension, loft, refurbishment or renovation — from early idea to delivered project.
Start here →Planning approved — need a builder
High demandYou have planning permission or drawings and need a principal contractor to deliver the build.
Start here →Builder abandoned my project
Act fastYour contractor has walked off, gone bust, or the work has stalled. We assess and complete.
Start here →Landlord or investor
HMO conversions, rental refurbishments, and portfolio maintenance across London.
Start here →Architect with a client project
We price from your drawings, coordinate with your engineer, and protect design intent on site.
Start here →Block management or commercial
Planned works, void refurbishments, communal areas and M&E for managed residential buildings.
Start here →What we do
Three kinds of project. One disciplined way of running them.
Whatever the building, the risks are the same: an unclear scope, drawings that can't be built as drawn, and nobody holding the whole picture. That is the part we take responsibility for.
Residential
Extensions, loft conversions, refurbishments and structural alterations for homeowners — from a single package to the whole house.
Commercial
Refurbishment, fit-out and conversion work for landlords, investors and businesses — scoped, programmed and coordinated around occupied or income-producing buildings.
Bespoke
Higher-specification and one-off projects where design intent matters — working alongside your architect or designer to protect the detail through to handover.

How we can help
Support at the stage you need it
You don't have to hand over the whole project to get our help. Start with a review, or bring us in for the stages where you want certainty.
Project review
A second pair of eyes on drawings, quotes or a stalled project. We tell you what is missing, what is risky and what to do next.
Pre-construction & procurement
Turn drawings into a buildable, itemised scope. Structural, Building Regulations and party wall questions answered before anyone prices.
Coordination & assurance
You keep your trades or designer; we manage programme, sequencing, quality checks and Building Control liaison.
Complete delivery
One team from pre-construction to handover, with the scope, programme and payment stages agreed in writing before work starts.
Have plans or drawings?
Get them reviewed before anyone prices them
Planning drawings are rarely enough to build from. We check them for what is missing — structural details, Building Regulations, party wall, drainage and services — and give you a clear list of what is needed to get accurate, comparable prices.
- ✓Buildability and sequencing issues flagged early
- ✓Gaps between drawings and a priceable scope identified
- ✓Honest budget guidance against what is actually drawn
- ✓A clear recommendation on the next step
House Extensions
Rear, side return, wraparound and double-storey extensions — including the kitchen, steels, drainage and finishes that go with them.
Loft Conversions
Rooflight, rear dormer, hip-to-gable, L-shaped and mansard conversions, with the staircase, ensuite and fire-safety works coordinated.
Associated & standalone works
Bathrooms & Ensuites
Ensuites for loft conversions, family bathrooms and wetrooms — as part of a larger project or on their own.
Kitchen Renovations
New layouts, structural openings, plumbing, electrics and finishes. Part of an extension or standalone.
Full Refurbishments
Single-floor or whole-house refurbishment, including back-to-brick strip-outs on period property.
Structural Alterations
Steel beams, load-bearing wall removal and chimney breasts, coordinated with your structural engineer and Building Control.
HMO Conversions
Fire compartmentation, emergency lighting and licensing-driven works for landlords and investors.
Garage Conversions
Integral or detached garages converted to habitable rooms, with Building Regulations sign-off.
CCTV & Security
Available on every rcbGroup project — cabling hidden during the build, cameras placed with privacy in mind, remote viewing set up at handover.
Bespoke, commercial & public sector
Not just homeowners
The same disciplined approach — clear scope, written terms, coordinated delivery — works for high-end one-off homes and for professional clients running larger or repeat programmes of work.

For landlords & commercial →Why clients choose rcbGroup
The work that prevents problems happens before anyone is on site. That is where we put the effort.
Scope before price

Coordination, not just construction
Architect, structural engineer, Building Control, party wall surveyor and trades — kept in step, with one point of contact.
Written terms before work starts
Scope, programme, payment stages and how variations are handled are agreed in writing before the first day on site.
