Builders in Barnet

Structure first, finishes last

Every job we run in Barnet starts with the parts you never see again: foundations dug to the depth the ground actually needs, steels sized by an engineer with padstones and fire protection, and a weathertight roof before a single plasterboard sheet arrives. Finishes are the easy part once the shell is right.

The EN4, EN5 and N20 building stock

Barnet is Victorian and Edwardian terraces in New Barnet, large 1930s semis across East Barnet and Whetstone, and substantial detached property at Totteridge. We survey what is actually there — wall construction, floor build-up, drain runs and roof type — and price from that, so the quote reflects your house instead of a generic square-metre rate.

One team, one programme

You deal with Gabriel from the first site visit to the final snag. Trades are sequenced in writing — groundwork, structure, roof, first fix, plaster, second fix, decoration — so nobody arrives to a job that is not ready and the Barnet programme does not quietly drift by a month.

Building control and paperwork

Building regulations approval, structural calculations, party wall notices where a shared wall is involved and London Borough of Barnet conditions are all handled as part of the job. You get the inspection sign-offs and certificates at the end, which is exactly what a solicitor asks for when you sell.

Building work across Barnet

Barnet is about an hour from our base, so we take on EN4, EN5 and N20 work as whole projects with a settled programme rather than piecemeal days. Small structural jobs run one to two weeks, a single-storey extension eight to twelve, and a full refurbishment two to four months.

London terraces and party walls

Terraced and semi-detached work in EN4 and EN5 nearly always triggers the Party Wall Act. Notices, schedules of condition and award timings are handled properly at the start, because a party wall dispute stops a build faster than any weather.

Side returns and rear infills

The classic Barnet gain is a side return infill with a rear opening into the garden. Done well that needs a designed steel frame, a warm flat roof detail that will not leak, and drainage moved before the slab goes down.

Conservation areas and Article 4

Monken Hadley, Totteridge and parts of Whetstone have conservation and Article 4 controls, so permitted development often does not apply. We work from the consented drawings and Barnet Council conditions rather than assuming.

What does an extension cost in Barnet?

A single-storey rear extension in EN4, EN5 and N20 typically runs £1,700 to £2,300 per square metre for the shell and standard finishes, with kitchens, bathrooms and glazing priced separately. Groundwork, drainage and steelwork are itemised so you can see where the money goes.

Do you give fixed prices or estimates?

Fixed written prices, itemised stage by stage, once we have drawings or a measured survey. Where something genuinely cannot be known until the floor comes up we say so and set a provisional sum rather than hiding it in the total.

Are you insured and do you offer a guarantee?

Yes — public liability insurance, and a workmanship guarantee on structural and finishing work. Manufacturer warranties on windows, roofing and boilers are passed to you with the completion paperwork.

How soon can you start in Barnet?

Lead time for Barnet building work is currently around four to eight weeks for larger projects, and smaller structural jobs can often fill a slot sooner. Sending drawings early is what secures a date.

Do you handle planning and drawings?

We work with architects and structural engineers we trust and can introduce you, or build from drawings you already have. We check consented drawings against what will actually build on site — including London Borough of Barnet conditions — before pricing.

Can we live in the house while you build?

Usually, yes. We seal the working zone with dust protection, keep a clean route through the house, maintain water and heating wherever possible, and give you a weekly plan of what happens next.

Will you take on work another builder abandoned?

Regularly, and we see it in Barnet more than you would think. We survey what has been done, tell you honestly what has to come out and what can be kept, then price the finish as a fresh job with its own guarantee.

Do you build the whole job or subcontract it out?

Our own team does the structure, carpentry, tiling and finishing. Specialists we have used for years cover electrics, gas and structural engineering, and they are managed by us on a Barnet site rather than left to arrange themselves.
