New Build and Flat Conversion Contractor London: Delivering Developer Schemes up to £3m

For a property developer, the difference between a profitable scheme and a stalled one usually comes down to one decision: the main contractor.

At Berati Construction, we specialise in exactly the kind of work that mid-size developers take on — new build residential developments and flat conversions across London, from one to ten houses through to larger multi-flat schemes, with a typical project value of up to £3 million.

New builds and conversions are two sides of the same discipline, and we deliver both with equal confidence. On the new build side, we manage the full programme — groundworks, superstructure, weathertight envelope, services and internal finishing — with the cost and programme certainty developers need to protect their margin and hit sales dates.

On conversions, we turn tired or under-used buildings into desirable, lettable and saleable homes, whether that means splitting a period property into apartments or reconfiguring a commercial building for residential use.

Our recent portfolio shows the scale we are built for. In Hornsey, we delivered a ten-home new build residential development; in Swindon, a conversion into eight flats; and in Tunbridge Wells, a nine-flat scheme with a commercial unit at ground level. In Oxford, we created five luxury flats from a single conversion.

These are the formats — small housing schemes and multi-unit conversions — where our team is most effective, and where our experience translates directly into fewer surprises on site.

We are equally comfortable joining a scheme early, advising on buildability and value engineering before you commit, or picking up a fully designed and consented project and simply building it. Either way, you get proactive communication, accurate monthly valuations, and a site team that keeps neighbours, building control, and your professional team informed at every stage.

Because we directly manage our core trades, we can hold both quality and programme even as a scheme grows in complexity — which is exactly when developer margins are most at risk and when a dependable main contractor earns its place.

Why developers choose Berati

Behind every scheme is more than 30 years of construction experience and the accreditations that serious developers and their funders expect: ConstructionLine Gold, CHAS, NHBC, Gas Safe and SSIP. We can also work on a design and build basis, taking single-point responsibility from planning drawings through to handover, so you deal with one accountable team rather than a fragmented supply chain.

Just as importantly, we understand the commercial pressures of development. Programme certainty, tidy phasing, a clean health and safety record and a finish that supports your sales or rental values are built into how we work, not treated as extras. That commercial mindset is what allows our clients to plan their exit — sale or refinance — with confidence.
