Westfield Cottage, 40 Pentland Avenue, Edinburgh

Westfield Cottage is an Arts and Crafts house designed by Sir Robert Lorimer and built between 1896 and 1897. It is a roughly square building of two storeys and three bays, with a projecting service wing to the east. The design incorporates both traditional English and Scottish architectural features, including a round entrance turret, carved window sills, finialled gables, and a jerkin-headed roof to the rear. The exterior is of harled sandstone with red sandstone cills and dressings. The first-floor is slightly corbelled out on the south-west elevation, and the turret has an eaves course.

The south-west elevation, the principal facade, features an entrance turret recessed to the right; the front door is timber-panelled and recessed within a roll-moulded sandstone architrave. The lintel is carved with the inscription "GOD'S BLESSING IS MY HERITAGE" and three rose motifs. The main elevation is symmetrical, with a central bipartite window at ground level, flanked by quadripartite windows. At first floor level, there are three tripartite windows. The cills of the first-floor windows are inscribed with "BLISSIT BE ZE LORD FOR ALL HIS GIFTIS," "CONSTANTI PECTORI MORTAIIUM VMBRAE," and "LAVS ET HONOR DEO," reading from left to right. The north-west elevation has an irregular pattern of windows. A gable to the right incorporates a large staircase window and a smaller window displaying a central stained-glass panel at ground level. A single-story section is located to the left. The north-east elevation consists of a two-storey section with a half-piended roof, alongside a projecting service wing with flat-coped walls and a ball finial at the corner. The fenestration is in three bays, with windows of varying sizes. The south-east elevation features an advanced round turret, with windows at both floors and the front door. There is also an advanced stack and a blind gable, and a single-story section with two windows. A recessed service wing has a glazed timber side door.

Most windows are timber casements with leaded lights. The chimney stacks are corniced and rendered, with red and yellow clay cans. The roof is red tile, with red ridge tiles, and cast-iron rainwater goods, including a decorative hopper on the south-east side.

The interior features a tiled entrance lobby with a half-glazed timber panelled inner door. The dining room has an advanced chimney breast with flanking cupboards; the cupboard on the left has a two-leaf timber panelled door, while the one on the right has a glazed door. The fireplace has a roll-moulded stone surround and a decorative cast-iron grate with rose motifs. A large two-leaf door connects the dining room and the drawing room. The drawing room fireplace has a roll-moulded stone surround and a timber mantelpiece with a double shelf. A small sitting room, off the drawing room, contains a stained-glass panel and decorative plasterwork to the ceiling. Original ventilation units and working shutters remain in the dining room and drawing room, along with plain plaster cornices in the principal rooms. The interior doors are timber-panelled with original furniture. There is also a stained-glass panel in the bathroom window.

The boundary is defined by a flat-coped random rubble wall with gatepiers topped with ball caps.
