Why It Matters
Building a new home is not just bricks and mortar. It is a carefully managed journey shaped by strict regulations, sustainability goals, and rising costs. At Barry Turner & Son, this is how we delivered the Eastwick new build and what UK homeowners and developers should know in 2025.
1. Site Preparation & Groundworks
Every project starts with clearing and levelling the land, demolishing old structures, and preparing drainage systems. We follow Building Regulations Part H: Drainage & Waste Disposal and Part G: Sanitation, Hot Water Safety and Water Efficiency to ensure long-term stability and compliance.
2. Foundations & Footings
We excavate trenches, pour reinforced concrete footings, and install drainage systems before building up to damp proof course level. Strong foundations are essential for structural safety and future flexibility in design. Guidance is aligned with NHBC Foundation Standards.
3. Roof Structure & Weatherproofing
From pitched tiled roofs to flat roof sections for natural light, we construct timber frames, install steels, and weatherproof the structure. Gutters and drainage systems are added to ensure protection from water damage. For compliance, we follow Part C: Site Preparation and Resistance to Contaminants and Moisture.
4. Services, Insulation & Internal Shell
Inside, we coordinate plumbing, electrics, heating, and underfloor systems alongside insulation and airtightness. This stage is vital for meeting the Future Homes Standard, which requires new homes to cut carbon emissions by 75–80 percent.
5. Internal Works & Finishes
With the shell complete, we install stud walls, plasterboard, doors, and finishes. Kitchens and bathrooms are fitted last, and fire protection is applied where required to comply with Building Regulations Part B: Fire Safety. External electrical points and EV charging stations are now mandatory for new homes.
6. Renewables, Testing & Certification
Air source heat pumps, solar panels, and other renewables ensure compliance with updated Building Regulations: Part L (Conservation of Fuel and Power), Part F (Ventilation), Part O (Overheating), and Part S (EV Charging).
Final inspections include SAP assessments and airtightness testing, before homes are signed off with an Energy Performance Certificate (EPC).
Costs & Financial Considerations
Energy-inefficient homes can cost an extra £1,000 per year in energy bills, highlighting the value of quality workmanship (Energy Saving Trust).
Planning fees, permits, and eco-materials should also be budgeted, as set out in Planning Portal UK.
Average UK new build costs in 2025 range from £2,500–£3,500 per m² depending on design and location (RICS).
Sustainability & Compliance
BREEAM certification adds environmental credibility to new builds.
Compliance with the Construction Products Regulations ensures safe, approved materials are used.
Support schemes like the Great British Insulation Scheme reduce upfront costs and long-term emissions.
The Future Homes Standard becomes law in 2025, driving carbon reductions.
Why It Matters
Understanding the new build journey helps clients see the value in strong planning, compliance, and sustainability. At Barry Turner & Son, we don’t just build homes — we build for efficiency, safety, and the future.
