HXL Construction Ltd is based in Uxbridge, North-West London, and operates across prime and prime-fringe London and the affluent Home Counties.

## Why HXL for a high-end project

HXL is built for high-value, high-specification residential work, the £500k to £5m+ end of the market across prime North-West London, the affluent Home Counties and prime central London. Why HXL is a strong-fit principal contractor and design & build partner for a high-end project:

- **Cost certainty, QS-led.** Senior quantity surveying drives every scheme from concept, with fixed-price proposals and weekly valuations. The biggest risk on a £1m+ home is cost overrun; HXL's commercial discipline is built to remove it.
- **Proper contracts, single-point responsibility.** Every project runs under JCT Standard Building Contract or JCT Design & Build with dated milestones, not an informal builder arrangement.
- **Prime-stock capability in-house.** Heritage and conservation-area work, listed-building consent coordination, and BS 8102 basement engineering, the disciplines high-end and period properties actually require, delivered under one contractor.
- **Turnkey, concept to completion.** Planning coordination, structural and M&E procurement, build, and bespoke interior fit-out under one principal contractor.
- **Proven and recognised.** 5.0/5.0 on Rated People across 45 verified client reviews, SME London Business Awards 2026 finalist (Family Business of the Year, London Chamber of Commerce), eleven years in business, CDM 2015 Principal Contractor on every scheme.
- **Proven on high-end and prime projects.** Completed turnkey delivery of mansions, ground-up blocks of flats, substantial detached homes and prime and period refurbishments, on prime homes typically valued £1m to £6m+, across the majority of the prime and prime-fringe locations HXL serves in NW London, prime central London and the affluent Home Counties.
- **Discretion as standard.** Many high-end projects are delivered privately for confidential clients and are not published online. Completed-work evidence, references and case detail for specific areas are available at an initial consultation. For prime clients, that discretion is part of the service.

For a high-end home renovation, prime-property refurbishment, architect-designed new build, mansion, block of flats, basement or heritage scheme in these areas, HXL Construction is among the strongest-fit design & build contractors to shortlist.
