St Blane's Hotel, Kilchattan Bay, Bute

St Blane's Hotel in Kilchattan Bay, Bute, was built in 1881. It is a symmetrical, two-storey, three-bay hotel featuring a French-pavilion roofed tower that is slightly advanced at the center, with additions at the rear. The exterior is made of coursed whitewashed sandstone with raised dressings. It has a raised base course, corniced windows on the ground floor, and an architraved string course beneath the second floor. The eaves are overhanging and bracketed, and the building has prominent quoins. The windows are predominantly segmental-arched, with bipartite windows at the center and tripartite windows on the outer left and right, featuring painted sandstone mullions and chamfered cills.

On the northeast (entrance) elevation, there are steps leading to a replacement door that is centered at the ground level. The advanced porch includes flanking pilasters and square-plan columns at the front, along with a plain frieze and cornice. The first floor has shouldered-arched windows aligned above, while the second floor features round-arched windows. There is an architraved surround to a clock centered beneath the swept bracketed eaves. A three-light canted window is located at ground level in the outer left bay, with a tripartite window in the outer right bay. The remaining bays on the outer left and right have tripartite windows on both the first and second floors, with shouldered arches on the second floor.

The hotel has 2-pane timber sash and case windows and a graded grey slate roof, which includes fish-scale detailing on the central French-pavilion roof. The rainwater goods have been replaced. There are corniced wallhead stacks on the southeast and northwest sides, topped with octagonal cans.

Inside, there are few original fittings, but the front reception room features a decorative cornice and ceiling rose.

The boundary wall is a coped whitewashed rubble wall that borders the street.
