New Builds in Cornwall — From Foundations to Keys
If you're planning a new build in Cornwall — a family home on a plot you've bought, a self-build on inherited land, a barn replacement, or a knock-down rebuild — you need a builder who can take it from a hole in the ground to a finished house with one phone number for the whole project. That's what L W Construction does. NVQ-qualified bricklayer, over 20 years of construction experience, £1 million public liability cover, and 5.0 stars across 20 Google reviews.

What a New Build in Cornwall Actually Involves
A new build is the ground-up construction of a single-family home — from clearing the site and digging foundations to handing over the keys with everything plastered, plumbed, wired, and tiled. In Cornwall, a typical new build is a 3- or 4-bedroom detached house on a plot with planning consent, taking 9-14 months from groundworks to completion depending on size, specification, and weather.
A new build is the largest project most homeowners ever commission. Getting the right builder matters more here than on any other job — the cost of fixing a builder who walks off halfway is measured in months and tens of thousands of pounds. Cornwall homeowners who self-build or commission a new build want a single, accountable point of contact across every trade, an honest price that holds, and a build sequence that doesn't stall waiting for one specialist who never turns up.
High-Spec Builds We Take On
Plenty of the bigger Cornwall jobs we take on now sit at the premium end — architect-designed family homes, often on substantial plots. We also take on commercial building work. Here's the kind of high-spec build we handle:
Architect-designed new homes.
You've already got an architect engaged through design and planning. We come in for the build phase — working to their drawings, attending the site meetings, flagging anything in writing, and keeping the build true to what the architect signed off. We don't replace your architect; we build what they've designed. Most of our high-spec clients come to us with their architect already in place, and we work with that team.
Highly insulated, low-energy homes.
Tight, well-insulated, draught-free builds with mechanical ventilation and high-spec glazing. What that means on site: every junction gets thought through before the blockwork goes up, the airtightness detailing goes on as we build rather than being patched in later, every pipe and cable penetration gets sealed properly, and we get the air-tightness test booked before the walls are boarded so anything that needs fixing is still easy to reach. We build to the standard; the certification side stays with your architect.
Oak-frame and traditional Cornish homes.
Green-oak structural frames with brick or stone infill, slate roof, and the traditional Cornish detail — granite quoins, slate hanging on gables, lime render. The frame goes up over a week or two with the frame supplier on site, then we close it in with traditional masonry. Common across rural Cornwall. Suits a home that looks like it belongs in the landscape rather than dropped on it.
Barn replacements and countryside plots.
Cornwall has a strong rural self-build market on old agricultural buildings. We work alongside the planning consultants at the application stage, then take the build from demolition of the old structure through to you moving in. Foundations matter more here — an old agricultural slab is rarely deep enough for a house, so re-founding to the engineer's design is standard. We've done barn replacements where the original walls were kept for character and where they came down entirely.
Conservation-area and listed-property work.
A new build in a conservation area or AONB, or a new wing on a listed property — both need careful planning input and sign-off from Cornwall Council's conservation officer. Materials matter: matched stone, lime mortar, the right slate, hand-formed roof tiles where they're needed. We've worked on conservation-area sites in central Truro, Falmouth, St Ives, and Penzance. Where the constraint is tight we talk to the conservation officer early and build the material spec around what they'll accept.
Types of New Builds We Handle
Single-family detached homes
— the most common Cornwall new build. 2-5 bedrooms, 90-300 m². Most are timber-frame or traditional block-and-brick. We work either spec.
Knock-down rebuilds
— existing property demolished (residential, ≤2 floors, within our insurance scope), foundations dug, and a new home built on the same plot. Common where an older bungalow makes way for a larger family home.
Self-build projects
— you've bought a plot, secured planning, and want a builder to take it from there. We handle the full build under one contract. You're hands-on with finish decisions; we're hands-on with the build.
Barn replacements + countryside infill
— Cornwall has a strong rural-self-build market. Where planning allows, we replace dilapidated agricultural buildings with new family homes, working alongside architects and planning consultants.
Plot purchase + build packages
— for clients who've already engaged a separate plot agent or architect, we step in for the build phase only.
We take on commercial building work too — new commercial premises and units alongside domestic new builds. Whatever the project, we're straight about whether it's the right fit for us at the site visit.
Benefits of Building With L W Construction
You're not project-managing the trades.
Most Cornwall self-builders end up coordinating their own electricians, plumbers, and roofers because their main contractor stops returning calls. With us, every trade goes through Luke. You make decisions; we make the calls.
Your build sequence is locked.
Each stage has a start date and an expected duration before we lift a tool. Weather and material lead times can move dates by days, but the sequence holds. Surprises are flagged early, not buried.
Your budget doesn't quietly grow.
Variations get a price and your signature before any extra work happens. If we hit ground conditions or design changes that affect cost, you know the same day. No surprise final invoice.
Your finish quality is consistent.
Brickwork is mine (NVQ + Diploma Level 3). Plastering, roofing, electrics, plumbing all go to trades I've worked with for years and won't put on a job unless they sign off their own work.
Your house is insured during the build.
£1 million public liability cover via Zurich Tradesman Insurance, on file and verifiable. If something goes wrong during construction, you're protected.

What Drives the Cost of a Cornwall New Build
A new build is the biggest project most people ever commission, so we won't pretend a number on a website means anything before we've seen the plot. A standard three- or four-bedroom family home is a high-six-figure project ground-up (land and planning on top of that); a larger or higher-spec house runs into the next bracket. What we will do is be straight about what moves the price up or down:
- Plot conditions. Sloping plots, poor ground, or a high water table all add to the groundworks.
- Specification. A standard family-home spec versus a high-insulation, low-energy spec changes the structure, the glazing, the insulation, and the services significantly.
- Roof complexity. A simple gable roof is the cheapest; hipped, mansard, or multi-level roofs cost more.
- Finishes. Standard tiling, a mid-range kitchen, and painted walls keep the budget tight. Stone, bespoke joinery, and designer fittings push it up.
- External works. A driveway, fencing, and basic landscaping add a chunk on top. A full garden design with terracing and walls is its own quote.
We give a fixed-price quote after a site visit. Any variations during the build are priced and signed off by you before the work happens — no surprise final invoice.

Frequently Asked Questions
How much does a new build cost in Cornwall?
A new build is the biggest project most people commission, so we won't put a number on it before we've seen the plot. A standard three- or four-bedroom family home is a high-six-figure project ground-up (land and planning on top of that); larger or higher-spec homes run into the next bracket. The price moves with plot conditions, specification, roof complexity, and finishes. We give a clear, itemised fixed-price quote after a site visit so you can see exactly what's included.
How long does a Cornwall new build take?
9-14 months for a typical 3-bedroom house from groundworks to keys, weather depending. Larger or more complex builds (4+ bedrooms, complex roofs, premium spec) run 12-18 months. The schedule is locked in writing before we start, with weather and material lead times flagged as the variables that can move dates. We keep you updated at every stage so you always know where the build is.
Do I need planning permission or building control for a new build?
A new build always needs full planning permission and Building Regulations approval. We help guide you through it and recommend planning consultants and structural engineers we work with regularly. The planning application itself is usually handled by your architect or planning consultant; once consent is granted, we make sure the build matches exactly what's been approved and we liaise with Cornwall Council Building Control at every required inspection.
Will the site be messy and disruptive?
A new build is a working site, but we keep it organised and tidy — materials stacked safely, the site fenced, deliveries managed, and a daily clean-down. We're respectful of you and your neighbours throughout. The handover walk-round is a clean, finished property, not a building site for you to tidy. Site clearance, skip hire, and final clean-up are all included in the quote.
What deposit or payment schedule do you work on?
We work on staged payments based on progress — a materials deposit at the start, then milestone payments as the build hits each stage (slab, walls, roof, first-fix, second-fix), with the balance on practical completion. No large cash sum up front. You can always see what you're paying for at each point, which keeps the whole thing transparent.
Do you clean up the site?
Yes. Site clearance, skip hire, and final clean-up are included in every quote unless you'd specifically prefer to handle a skip yourself (which we'll flag upfront). The handover walk-round is a clean, finished property — not a building site for you to tidy.
Can I see examples of new builds you've completed?
Yes — our Instagram (@luke_walker_construction_) has finished and in-progress projects with 54 posts of real Cornwall builds. You can also call and arrange to visit a recently completed project (with the homeowner's permission). That's the strongest reference we can offer.
