Extensions
Single storey rear and side extensions. We are strongest below ground and at the interfaces — which is where extensions actually go wrong.
Single storey, done thoroughly
We build single storey rear and side extensions and garden rooms. We do not do two storey work or loft conversions, and we would rather tell you that now than take the job and subcontract the difficult half of it.
Within that, we are comfortable with the parts that cause most of the trouble: foundations near trees or drains, building over or close to a public sewer, existing drainage that has to be diverted or rebuilt, and the junction between old and new at the roof and the threshold.
Those are groundworks and detailing problems, which is what we have always done.
Foundations and drainage
The excavation is where an extension budget is won or lost. Trees, made ground, an old outbuilding base, a drain running exactly where the footing needs to go — all of it turns up after the digger arrives unless somebody looks first.
We dig trial holes before we price where there is any doubt, survey the existing drainage rather than assuming the plan is right, and put a realistic foundation depth in the quote rather than a hopeful one.
- Trial holes before pricing where foundations are uncertain
- Existing drainage surveyed, chambers lifted and levels taken
- Build-over agreements handled where a sewer is involved
- Tree proximity assessed and foundation depth designed for it
- Ground floor to current U-values with insulation carried up at the perimeter
