Drawing 5 shows a design for a warm air stove proposed by W & M Feetham, stove-makers. The plan is in Soane's hand and the elevation in Feetham's hand. The stove was intended for the ground floor stairwell, sharing a flue with the drawing room fireplace (as the plan shows). SM archive j/1/1 is an estimate from Freetham for the stove, with a description of its distribution of warm air on the first floor landing: 'a new handsome / Grecian pattern warm air stove / 4 ft by 2 ft and 3 ft 11 in high / the front corners rounded to be placed / in the passage opposite the stair case / with flue to take smoke into the chim- / ney in wall adjoining a recess to be made 6 in deep into the wall to receive stove / and the front of stove to project 1 ft 6 in / before the front of wall the warm- / air to be conveyed from the above / stove to the landing over it by a / (?) chacing being cut out in brick-work / 12 in wide by 4 in and a neat brass / ventilator ino the landing floor or / skirting to admit the warm air...'(SMA j/1/1). Feetham estimated it to cost £63.0.0, including £3 for coach hire.
