Groundworks Contractor
Everything above the ground is only ever as good as what's below it. Humphries Construction is groundworks-led: we set out, dig, drain and pour the slab so the trades that follow inherit a job that's square, level and dry, not one they have to fight.

Home Extensions Builder
A well-built extension changes how a house feels every day and adds real value the day you sell. We take extensions ground-up: foundations, structural steels, brickwork, roof, plaster, second fix, all managed from one contract, with a fixed written price and a 10-year structural warranty in the paperwork.

Garage Conversions
Most integral garages are wasted space. A properly converted garage adds a full room, bedroom, home office, gym or utility, for a fraction of an extension's cost, and finishes to the same standard as the rest of your house. We handle everything from insulation and building control to plaster and second fix.

New Build Groundworks
Whether you're a self-builder on a single plot or a developer running a small residential scheme, we deliver groundworks packages that hand a clean, accurate platform to the frame contractor, set out to your engineer's drawings, on programme, and priced on either a fixed package or day rate depending on scope certainty.

Driveway Installation
Most failed drives look fine on day one. The rocking blocks, subsiding kerbs and puddles show up two winters later, because the sub-base underneath was rushed. We're groundworkers first, so your drive is dug, drained and compacted correctly before the finish surface ever touches it.

Foundations & Footings
Foundations are the one part of a build that has to be right, because everything else depends on them and nobody sees them once they're covered. We dig to the depth ground conditions and your engineer's calcs actually demand, coordinate the building control inspection, and pour to spec.

Bricklayer
Bricklaying is a trade you notice when it's wrong, bowing courses, inconsistent joints, mismatched mortar, weep vents in the wrong place. We build brickwork to gauge, on plumb, with clean pointing that stays true through frost and rain.

General Builder
Not every job is a full extension. Sometimes you need a wall out, a steel put in, a bathroom relocated, a structural repair sorted or an old kitchen area reconfigured properly. General building work needs the same discipline as a big job, priced honestly, planned properly and finished cleanly.

Patios & Landscaping
A patio should sit flat, shed water away from the house and still be that way in ten years. The market is full of patios laid on sand and hope. Ours are laid on a proper compacted sub-base with a full mortar bed, correct falls, and drainage that actually goes somewhere.
