Sunninghill Garden Rooms: a local specification for SL5 properties

Garden Rooms in Sunninghill is most of what we do. Sunninghill is a village strip along the A329 with Victorian terraces around the high street, 1930s detached homes on the upper roads and a smaller cluster of newer build. Pine-belt sand and the elevated position mean drainage falls matter as much as sub-base depth. For a garden room on a Sunninghill plot we usually plan around Article 4 / conservation rules that affect permitted development on a small number of streets, so the spec we quote is shaped by what actually goes wrong on this side of Berkshire.

What changes the specification here

Sunninghill 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 SL5 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.
