House construction begins with site surveys, soil testing, and design work. Planning permission or permitted development checks follow.
Once approved, contractors clear the site, set out the foundations, and install drainage.
The structural frame is then built, followed by external walls, roofing, windows, and doors. After the house is weather tight, internal systems such as electrics, plumbing, heating, and insulation are installed. Finishing work includes plastering, flooring, joinery, kitchen and bathroom installation, and final decoration. The project concludes with inspection, snagging, and certification.
A new build is a completely new structure built from the ground up. It usually offers more design freedom, predictable timelines, and modern standards.
A renovation involves modifying, repairing, or upgrading an existing building.
Renovations often require careful integration with old structures, can uncover hidden issues, and may need additional structural assessments or permissions. Renovation projects can be quicker but sometimes carry more unpredictability.
Costs vary by region, design complexity, and materials. On average, new build construction generally ranges from approximately one thousand five hundred pounds to three thousand pounds per square metre.
Higher end designs, premium finishes, or difficult site conditions can increase costs. Professional fees and land preparation should also be included in the budget.
Homeowners should look for experience with similar residential projects, clear and detailed quotations, good communication, and evidence of quality workmanship. Checking insurance, certifications, reviews, and previous client references is important.
A reliable contractor will provide guidance on regulations, timelines, and costs, and will maintain transparency throughout the project.
Residential construction often includes a structural warranty, typically lasting ten years, which covers major defects. Contractors may also provide workmanship guarantees for specific periods and product manufacturers may offer their own warranties on items such as boilers, windows, or roofing materials.
These guarantees help protect homeowners from future issues and provide confidence in the build quality.
Common features include enhanced insulation, energy efficient windows, heat pumps, solar panels, mechanical ventilation with heat recovery, and water saving fixtures. Many homeowners also request environmentally friendly materials, reduced energy consumption designs, and smart home systems for monitoring usage.
These measures help reduce running costs and support modern environmental standards.
Modern methods of construction include modular homes, panelised wall systems, structural insulated panels, timber frame systems, and off site manufactured components.
These methods can reduce build time, improve quality control, and minimise waste.
They are increasingly popular for residential projects aiming for higher energy performance and faster delivery.
Building services are installed after the structure is complete and the property is weather tight. First fix installations include running pipes, cables, and ducting within walls, floors, and ceilings.
Second fix installations include fitting switches, sockets, radiators, boilers, ventilation units, and sanitaryware. All systems must comply with UK regulations and be tested before handover.
Residential projects must comply with the Building Regulations, which cover structural safety, fire safety, drainage, electrical systems, insulation, accessibility, and energy performance.
Planning permission may be required depending on the size and design. Work must be inspected by building control officers or approved inspectors at key stages. Electrical and gas work must be carried out by certified professionals.
Common delays include weather disruptions, material shortages, unforeseen structural issues, and changes to the design. Delays can be reduced through thorough planning, early ordering of materials, clear communication with contractors, and avoiding unnecessary changes once construction begins.
Regular project management checks also help keep the build on schedule.
