The brief
The client wanted a contemporary family home that maximised natural light, separated public and private zones, and stayed within a fixed budget. The site sloped gently toward the rear, requiring careful setting-out and a stepped foundation.
Scope of works
- Architectural plans, structural coordination and MEP layout
- Substructure: stepped strip foundation on improved ground
- Superstructure: stone walling, RC columns, beams and slab
- Roof: timber trusses with stone-coated tiles
- Internal finishes: porcelain tiling, hardwood joinery, painted plaster
- External works: driveway, perimeter wall, basic landscaping

Challenges & how we handled them
Sloped site, fixed budget
A 1.4 m fall across the rear of the plot meant the foundation strategy and earthworks had to be priced before the client committed. We absorbed the variance by re-sequencing the substructure and value-engineering the perimeter wall.
Long-lead joinery
Hardwood for the staircase and main doors was procured early in week 6 to avoid pushing the finishing programme. We tracked it weekly against the master schedule.
Outcomes
- Delivered on the agreed programme with snag-free handover
- Final cost within 4% of the contract sum, with no scope cuts
- Zero lost-time incidents across 9 months on site
"We moved in on the date promised. Snagging took two days, not two months."
