Finchampstead Garden Rooms: a local specification for RG40 properties
Garden Rooms in Finchampstead is most of what we do. Finchampstead is a low-density village with substantial detached homes on Finchampstead Ridges, period cottages around the church and 1960s-80s estates towards California Crossroads. Pine and gravel ground drains well but loses fines easily on block-paving joints. For a garden room on a Finchampstead plot we usually plan around south-facing positions where overhang and external shading become important, so the spec we quote is shaped by what actually goes wrong on this side of Berkshire.

What changes the specification here
- Finchampstead is inside our 30-mile core area, so site visits are arranged within a week and project supervision is daily, not weekly.
- We've spent enough time on RG40 streets to know which ground conditions matter for a garden room - the high water table plots where screw-pile foundations beat traditional concrete slabs that gets missed when a national firm quotes from a desk.
- Quotes are written, fixed and broken down by stage, with the same crew on site from day one through to clean-down.
