Trigon House Including Attached Garden Wall And Loggias On North-West

Trigon House is a country house built around 1911, designed by architect Philip Sturdy, and enlarged in 1928 using stone salvaged from the demolished 18th-century South Bridge in Wareham. The house is in the Arts and Crafts style and features brick walls with decorative brick cornices at the eaves and verges, along with a patent tile roof. It has two storeys and a main front with a central range that includes stone mullioned windows on both floors and gable projections at each end. There is a moulded stone string course at the first-floor level, and the gables have canted mullioned bay windows with herring-bone tiling between them, topped with hipped tiled roofs that have ornamental cornices made from half-round tiles.

At the left end, there is a canted gabled projection designed similarly. Attached to this is a canted stone-built extension from 1929, which includes a Dining Room block with a stone slate roof and moulded parapet, as well as two octagonal single-storey structures—a porch and a store room—connected by an open carriage porch with a four-centred arch. Above the entrance door is a re-used date stone from 1755, and at the rear of the store, there is a re-set stone inscribed "This bridge rebuilt 1778." The Dining Room block features an octagonal battlemented turret, and at the rear of the Dining Room, there is a large canted bay window with mullions and transoms that contains heraldic glass, with a gabled projection above it.

Internally, the Dining Room has a Greek Cross plan with four large stone arches of two orders supported by stone piers, and a timber gallery with carved shields. Attached to the northwest side of the house is a stone garden wall with bowed projections and recessed loggias, all made from re-used stone from the bridge. This building is an interesting example of Arts and Crafts design.
