Home Extensions

Single-storey, two-storey, kitchen-extensions and garden rooms. We've delivered over sixty in the South-East — most without ever touching planning, the rest taken from drawing through to permission with our in-house architectural partner.

Where it matters, we sit down with you and your architect together — so the buildable matches the drawn, and the price stays where the contract sits.

Full Renovations

Strip-back, re-wire, re-plumb, re-plaster. We take period homes, derelicts and tired terraces and bring them to A-rated, modern-living standard without losing the character that made you buy them.

Stone walls re-pointed by hand. Old joists sistered, not replaced. New M&E hidden behind the right finishes. Every job we do here is a build we'd live in ourselves.

  • Period & heritage homes
  • Full first-time refurbishments
  • Re-wires & re-plumbing
  • Lime plaster & restoration
  • Internal reconfiguration
  • BER upgrades to A-rated

New Builds

One-off houses on private sites. Architect-led or design-and-build. From foundations to handover, with HomeBond cover and full BER certification on every project.

Twelve to eighteen months on the site, depending on scale. A fixed-price contract, a written programme, and a single point of contact for the duration.

  • Architect-led one-offs
  • Design-and-build packages
  • Passive & nearly-zero energy
  • Timber-frame & ICF builds
  • HomeBond ten-year cover
  • BER certification included

Groundworks

Site clearance, foundations, drainage, percolation testing and entrance works. All plant operated by our own SOLAS-ticketed team — no waiting on subbies, no diary clashes, no surprise day-rates.

For self-builders, we'll take the site from raw field to slab-ready and hand back to your contractor. Or carry through to first-fix and beyond.

  • Foundations & rafts
  • Drainage & percolation
  • Site entrances & access
  • Retaining walls & landscaping
  • Septic tanks & treatment

Project Management

One contract, one point of contact, one programme. We handle suppliers, sub-trades, certs and snag from day one — even if we're not the principal contractor on site.

If you've got an architect and a builder already lined up but want someone keeping the dates honest, this is the service. We sit between you and the build.

  • Programme & schedule control
  • Supplier coordination
  • Sub-trade management
  • Cost monitoring & variations
  • Certification & sign-off
  • Snag list & handover

Energy Upgrades

Deep retrofits, external wall insulation, attic insulation, heat-pump installs and ventilation upgrades. SEAI grant paperwork is included — we lodge it for you and reflect the grant directly in your contract price.

One-stop-shop registered with SEAI. From a single insulation upgrade to a full Better Energy Homes deep retrofit, we run the whole programme in-house.

How It Works

Four stages. One contract.

Every Hartstone project — whether it's a back-garden room or a 280m² new-build — runs through these four stages. Same paperwork, same accountability, same crew.

01
Stage One
Consultation

A free site visit, a real conversation about budget and scope, and an honest answer on whether we're the right crew for the job.

02
Stage Two
Fixed Quote

Itemised pricing within ten working days. Materials, labour, plant, contingency — all of it on one page, in one number.

03
Stage Three
Build

A written programme, weekly progress photos, a single point of contact, and our own crew on site Monday to Friday.

04
Stage Four
Handover

Snag list closed, certs lodged, site cleaned. A twelve-month aftercare warranty on every project as standard.
