141, 143, 145 High Street, Montrose

141, 143, and 145 High Street in Montrose is a late 19th-century, three-storey, three-bay house designed in an L-plan with Jacobean detailing. The front is finished in sandstone ashlar with a stugged texture, while the rear features plain rubble stone, and the side and gable ends are also made of rubble stone. The building has a base course, a cill course at the first floor, and a string course at the second floor, all with chamfered margins.

On the east elevation, the central bay is slightly advanced and features a blank ground floor, a blinded window at the first floor adorned with a billet ornament at the head, and a blinded slit window at the second floor with a hoodmould. Above this, there is a prominent stone wallhead dormer with a canted oriel window supported by a consoled eaves cornice, and a curvilinear gablehead with a keystone flanked by square stacks. The bay to the right has a window at the ground floor with a small additional window to the side, a window at the first floor in recessed margins with a billetted head, and a window at the second floor with a hoodmould. The bay to the left has a door offset to the left, a window to the right behind a pair of octagonal columns on bases that support a canted window at the first floor, and a window at the second floor with a hoodmould.

The south elevation features an advanced gable end to the right with a window in the gablehead, and a two-bay wing to the left with a later two-storey harled addition. The west elevation has an advanced blank gable end to the left with a two-storey addition extending to the right, while a single bay of the original house is set back. The north elevation is asymmetrical, harled at the ground and first floors with irregular fenestration, a blank second floor, a gable to the left, a later dormer in the centre, and a two-storey addition to the right.

The first floor east elevation features 8-pane timber sash and case windows, with various modern replacements elsewhere. The roof is covered in grey slate, with stone skews and elaborate corbelled, panelled, and corniced skewputts, along with stone finials on the east elevation. The north and south elevations have corniced ashlar gablehead stacks, while the west elevation has rendered brick stacks.

The interior of the ground floor has been converted for use as a medical practice, with apartments above, although these were not seen in 1997.

The property is enclosed by a rubble stone boundary wall to the south, which has stugged ashlar gatepiers with corniced caps that open onto Swapps Close from the garden of No. 149, possibly originally leading to No. 145.
