Mackay Hugh Baillie Scott, Blackwell, 1900, Bowness-on-Windermere, Cumbria, England. Positioned at the brow of a hill, the house has a masculine feel, but the light, tranquil drawing room offers a distinct contrast. Its inglenook fireplace, set amid ornate white plasterwork, becomes a carefully conceived room within a room.
