Detmar Blow produced this initial estimate for the cottage:
‘Estimate for the erection of a cottage at Stoneywell Hill, Markfield, Leicester for Mr Sydney Gimson in accordance with plans by Ernest W Gimson.
Making solid with rubble the spaces under the room floor, laying a thin layer of cement concrete to receive the boards.
Laying all other ground floor with slate and bedroom floors with plaster on laths, providing a slate riser and bucket to WC, a cottage range for kitchen value £3-0-0 and fire brick hobs with bars to bedrooms, plastering the walls inside with one coat of cement, and one of lias lime plaster with no hair, plastering or slating window seats and ledge including all labour and materials, used by masons, for the sum of £428-0-0.
Water service extra.'
It was a difficult site, with hilly outcrops of hard rock. Gimson boldly took the decision to use these as the foundations wherever possible. At the highest point, set on the natural foundations, was a massive stone chimney its design articulated by slabs of slate. The cottage continues downwards in an open zigzag from this point, following the natural contours of the slope. Local stone including large rough boulders and old dry-stone walls was used for the building. The stones weren’t shaped by tools but carefully selected and positioned to fit. The original thatched roof was replaced by slate tiles after a fire in 1939.
