The Build Process

Appoint Contract Administrator & Inform Planners

We recommend appointing a Contract Administrator (architect, QS or other qualified professional) when you go on site. They certify monthly valuations, manage changes, and protect your interests. Before work begins, check and discharge planning conditions and inform the planning department of your start date.

Clear Site

Install temporary access and clear the plot. With a Supply Only package, this is carried out by your main contractor.

Set Out & Dig Trenches

The house position and levels are set out; your engineer can check accuracy to avoid boundary/height issues. Trenches are then excavated for foundations.

Build Foundations

Concrete strip foundations are poured to the engineer’s drawings. Underbuild blockwork is taken to DPC, then hardcore, sand blinding and the concrete slab are installed. Drainage/sewerage is typically installed at this stage. A HebHomes representative inspects foundations to confirm suitability before kit delivery.

Erect to ‘Wind & Weathertight’

The kit arrives and erection begins. A typical four-person team erects most homes in ~7 working days (size/complexity/weather dependent). Works include fixing sole plates; erecting SIP/CPS walls, lintels and joists; installing floors, ridge and roof panels; internal vapour control; external membranes; non-loadbearing partitions and windows. The structure is now secure and weather-protected, but full sealing depends on exterior claddings and sealants.

Finish the Roof

While scaffolding is up, complete battening and roof coverings (profiled metal or slate), flashings and roof lights.

First Fix: Joinery, Plumbing & Electrics

Internal battening/framing proceeds; electricians run cabling; plumbers install pipework and underfloor heating; ventilation ducting is set; sound insulation is fitted. Plasterboard follows (insulated boards to external walls; fire-resistant behind stoves; moisture-resistant in bathrooms; thicker boards to ceilings for acoustics).

Second Fix

After taping/filling or plastering, finishes begin: hanging doors; skirtings and architraves; installing sanitaryware and connecting systems; fitting kitchen; laying floors; tiling; connecting heat pump and MVHR; final electrical fit-off.

External Finish

Timber cladding or outer leaf/render, guttering and final drainage connections progress in parallel with internal works (rendering is weather-dependent).

Finishing Touches

Decoration, landscaping and drive finishes (gravel, tarmac, planting). The house is almost ready for occupation.

Handover

The Contract Administrator certifies Practical Completion. Typically, valuations occur every four weeks and 5% retention is held through the build. At PC, keys are handed over, you assume insurance duties, and (subject to locale) you may occupy once the Completion Certificate is issued by Building Control.

Defects Period

During the (usually 12-month) defect period, record any snags/latent defects to be made good. The final retention is released once defects are rectified. If you chose our turnkey route, HebHomes organises NHBC/BOPAS warranties and coordinates Completion Certificate; otherwise your administrator arranges certification and warranty.
