The front part of the house is early 19th Century (C19) but with a rear wing which is early to mid 18th Century (C18).
It is mainly constructed of squared sandstone (smaller and more regular masonry in the front of the house), slate roofs. L-plan: early C19 3-unit front range built Two storeys and 3 bays, symmetrical; central doorway has simple moulded architrave with small cornice, panelled door and rectangular overlight with radiating glazing bars; 2 windows at ground floor and 3 above, all with raised sills and mostly 16-pane sashes. Low- pitched hipped roof; side-wall chimneys. Three-bay rear wing of 2 lower storeys has doorways to 1st and 3rd bays, with broad beaded jambs and lintels, between these a modern French window inserted in a formerly horizontal rectangular 3-light window; a 3-light window above this and a 2- light window above each door, all with flat-faced flush mullions and run-out sills and heads, and that in the centre with rectilinear leaded glazing in the outer lights; in angle with main range, an inserted oblique window at ground floor and a single-light window above (probably the left light of a former 2- or 3-light window otherwise covered by the C19 addition). Interior: entrance hall of front range has dog-legged open-string staircase with scrolled brackets, stick balusters, ramped handrail with wreathed curtail; reeded architraves to doorways and windows (which have internal shutters); thick partition wall between entrance hall and right-hand room suggests that this is a remodelling of the 4th bay of the earlier building; the rear wing, on a lower level, has inter alia, stop-chamfered spine beams, and a rectangular brick fireplace with rounded corners (early C18 type).
As further research is carried out on Felkirk House more information will be added.
