About KV Design & Build
A building contractor for residential and commercial projects across London and Hertfordshire.
Built properly.
KV Design & Build Ltd is a London and Hertfordshire building contractor delivering residential and commercial projects from planning through to handover. Our work spans home extensions, full-property refurbishments, kitchen and bathroom refurbishments, new residential builds, and commercial fit-outs for the hospitality, retail, and office sectors.
By managing construction under a single contract, we give clients a level of coordination and accountability that the multi-contractor model cannot. There are no handover gaps, no conflicting specifications, and no ambiguity about who is responsible for the result.
We operate across the full breadth of London boroughs and the Hertfordshire commuter belt, with our base in the Welwyn Garden City and Hatfield area. Whether it is a rear extension on an Islington Victorian terrace, a hospitality fit-out in Camden, a kitchen refurbishment in Brookmans Park, or a new-build residential property in St Albans, we bring the same standards and the same integrated approach.
How we work
Initial consultation
We begin with a site visit and a conversation about your brief, your property, and your goals. No charges, no obligation — just a clear picture of what is possible and what a project with us involves.
Planning and specification
We develop the scheme to planning and building regulations standard, working with architects and structural engineers as required. Where planning consent or pre-application discussions are needed, we manage that process. We handle structural calculations and coordinate specialist consultants.
Detailed specification and quotation
Before work starts, you receive a clear written specification and quotation. We scope the project thoroughly so you know what is included and what to expect. No hidden extras once the contract is agreed.
Build and coordination
Our construction teams and specialist subcontractors are coordinated through a single programme. We manage every trade on site, run regular client updates, and keep the project moving to programme.
Handover and snagging
We carry out a thorough snagging inspection before handover. Every item on the schedule is closed out before we sign off. The project is not complete until the standard is right.
Insurance & Compliance
All KV Design & Build Ltd projects are carried out by fully insured teams, working to building regulations standards. Gas and electrical works within our projects are carried out by appropriately qualified operatives.
Where we work
We work across London and Hertfordshire — from inner North London boroughs (Camden, Islington, Barnet, Hackney, Westminster, and beyond) through to the Hertfordshire commuter belt (Welwyn Garden City, Hatfield, St Albans, Potters Bar, Brookmans Park, and surrounding towns). Our base in the 01707 area gives us excellent road access across our whole operational area.
