11 Castle Terrace, Dundee

3 Castle Terrace in Dundee is a two-storey and attic terrace of houses and flats, attributed to architect James MacLaren and dated 1864. The building underwent alterations and conversion to flats by John Bruce and Sons between 1906 and 1908. It features coursed and snecked rubble with painted margins, doorpieces, and quoins, along with ashlar stacks and a slate roof. The windows were originally 2-, 4-, and 8-pane sash and case, though many have been replaced with out-of-keeping aluminium and uPVC. The windows have shouldered margins and cills that are bracketed at the first floor. The gables have deep eaves on exposed purlins and delicate bargeboard decoration, with moulded ridge and gablehead stacks and ashlar skews.

On the southeast elevation, there are 13 entrance doors with pilastered doorpieces and cast-iron brattishing. Doors numbered 1, 2, 3, and 4 have paired pilasters and flanking lights. There are also four close entrances with bracketed lintels, tiled with full-height Art Nouveau pattern tiles. A string course runs at the first floor. The elevation features 13 full-height canted windows with fishscale slate roofs at slightly advanced gables, and oculi at the gableheads of numbers 10, 11, 12, and 13. Moulded cast-iron rainwater goods, ornamental brackets, and hoppers dated 1864 at number 7 are present, along with roof lights.

The northeast elevation and the wall at Castle Street consist of a coped rubble wall with 14 entrance gates that partially mask seven projecting pyramidal-roofed service blocks. Doors at the first floor level are accessed by stone stairs, with some original two-leaf doors. There are six shouldered wallhead stacks, seven canted dormers, and three box dormers.

The wall and gatepiers include a rubble wall with rounded coping on the south side forming a private garden, with two pyramidal-capped gatepiers on the east and two parallelogram-section gatepiers on the west.
