RCB Design & Build is an Checkatrade-accredited, TrustATrader-endorsed principal contractor based at 347 Barking Road in East London. We deliver refurbishment projects across Portsmouth & Southsea and the surrounding Hampshire catchment — covering everything from initial feasibility through to final sign-off, under one contract, with one accountable team.
Portsmouth has a growing property market with strong demand for refurbishments and commercial projects. RCB has completed large-scale external insulation and render projects across hundreds of properties in the Portsmouth area. Victorian and Edwardian terraces in Southsea, post-war housing in the city, newer developments at Gunwharf Quays. HMO market is strong near the university. That mix of housing styles is exactly the kind of stock our team has been working on for more than 20 years — we know what is structurally possible, what planning will actually approve, and where surprise costs typically appear.
Why Portsmouth & Southsea homeowners choose RCB for refurbishment projects
Most local builders we meet on rescue jobs share the same pattern: a low headline price, a partial scope, no proper structural engineering input, and stage payments that aren’t tied to defined deliverables. We do the opposite. Every project starts with a written scope, a fully costed schedule of works, a structural design from a qualified engineer, and a programme you can hold us to.
For refurbishment work in Portsmouth & Southsea specifically: 1 hour 45 minutes from our East London base via the M3/A3. That short travel time means a senior member of our team is on site quickly when decisions need making, not booked in for the following week.

What’s included in a refurbishment project with RCB
Working in Portsmouth & Southsea: what to expect from us
Our team operates across PO1, PO2, PO3, PO4, PO5, PO6 and the immediately surrounding postcodes including Southsea, Gosport, Fareham, Havant, Chichester. We handle parking permits, skip licences, party wall coordination and neighbour notification as part of the standard contract — those are project costs we own, not items you discover halfway through.
Where conservation-area, listed-building or Article 4 restrictions apply locally, we factor heritage compliance into the design from day one. Where the local council has known quirks — particular pre-app processes, validation requirements or favoured materials — we use them to your advantage rather than discover them after a refusal.
Frequently asked questions
How long does a full house refurbishment take?
Most full refurbishments run 16–28 weeks depending on size and whether structural reconfiguration is included. Larger detached properties and HMOs can run 6–9 months.
Can I live in the house during the refurbishment?
Generally not — full refurbishments involve total strip-out, rewires and replumbs that make a property uninhabitable for much of the programme. We help clients plan the temporary accommodation window into the project.
Do you handle landlord refurbishments and HMO conversions?
Yes. We work with private landlords and small portfolio investors on refurbishment-to-rent and HMO conversion projects, including HMO licensing requirements and fire compliance.
How do you protect the client during a project of this size?
Full written contract, stage payments tied to defined deliverables, photo records, and we work as Principal Contractor with proper CDM 2015 documentation throughout.
