JR General Building Milton Keynes · Home Counties

Building work with the discipline of a proper site team.

Three generations of hands-on building experience: groundwork, brickwork, extensions, interiors, patios and driveways. Our own trades on site, the owner on the project, and every stage set out properly before the first dig.

Capability matrix

One site team. Every critical trade covered.

The site is planned as a sequence, not a shopping list. Groundwork, brickwork, roof structure, plastering, drives and patios are coordinated by the same owner-led team.

Built to feel different

No generic service tiles. This section works like a contractor capability board: what trade, where it sits in the build, and what it means on site.

01

Core build package

Building

From excavation to a plaster-ready shell.

02

External finish package

Patios & Driveways

Driveways, patios and surfaces built from the sub-base up.

Site standard

Built by people who know the next trade.

Why JR General Building

Less sales theatre. More site discipline.

The professional finish comes from the unglamorous things: proper set-out, clean sequencing, honest scope, and trades who understand how their work affects the next stage.

1

Owner-led delivery

The person quoting the work stays close to the project, coordinates the trades and keeps decisions moving on site.

2

In-house trades

Groundworkers, bricklayers and plasterers are planned as one team, so the job does not stall between separate contractors.

3

Written scope

Clear labour, materials, timing and payment stages before work starts. Less guesswork, fewer awkward conversations.

4

Clean handover

Protection, tidy working and a final walk-round before sign-off. The finish matters as much as the structure.

Build programme

Survey, quote, build, handover.

Good building work is calm because the sequence is clear. Every project moves through the same controlled stages, so you know what is happening, what it costs and who is responsible.

Stage
Checkpoint
What happens
  1. 01

    Survey

    Day 1

    Walk the property, check access, measure levels, look at drainage and record the practical constraints.

  2. 02

    Quote

    Clear scope

    Written scope with labour, materials, timings and payment stages before anything is booked in.

  3. 03

    Build

    Live works

    Owner-led coordination of groundwork, brickwork, plastering and the specialist trades needed on site.

  4. 04

    Handover

    Sign-off

    Final walk-round, snagging, tidy finish and sign-off only once the work is right.

From drawings to delivery

The build is managed as one connected system.

Extensions and structural projects fail when trades are treated separately. JR General Building keeps the whole chain visible: the dig affects the brickwork, the brickwork affects the roof, and the finish depends on both.

Extension specialists

More space, built like it belongs to the house.

The best extension does not feel bolted on. We match the structure, manage the awkward trades, and carry the finish through so the new space feels settled from day one.

What our clients say

Real words from real customers.

JR delivered our single-storey rear extension start to finish. Same crew on site every day, the owner on the project not just on the phone, and the finish on the brickwork is exceptional. We had a written quote, a programme, and the final number was the number on the quote.

Sarah M.

Hertford

Block-paved drive and a sandstone patio at the back. The sub-base work was the bit we couldn't see but the bit that made the rest of the job last. Three years on, not a settled paver in sight.

David & Ruth K.

Brentwood

Internal knock-through, new kitchen-diner. Skirting back on, plaster perfect, decoration-ready. The dust management alone was better than anyone we'd had in before — kids stayed in the house for the whole job.

Andrew T.

Romford

A garden wall that needed rebuilding and a small extension on the side return. City & Guilds-level brickwork — the bond and pointing match the original house. You can't see the join.

Emily R.

Loughton

Resin-bound driveway over an existing tarmac base. Smooth, no loose stones, drains beautifully. The team turned up when they said and finished when they said. Couldn't fault them.

James P.

Chelmsford

Two-storey rear extension. Big job. JR managed everything — groundworks, brickwork, roof, plaster — and brought in trusted electricians and plumbers on schedule. The handover walk-round was the easiest part of the whole 14 weeks.

Hannah G.

Enfield
