There are sepulchral structures that look like small wooden houses with span roofs.

With a span of 315 metres, the arch is the longest single span roof structure in the world.

His single span roof construction allowed him to build the new churches without the traditional subdivision into nave and aisles.

With the development of wide span roof structures the construction of large indoor ice rink stadiums became possible.

The steel frame allowed for an unsupported 80 ft (25 m) span roof structure and also provided good resistance to earthquake damage.

The church has a five-bayed nave 52' wide with an extraordinary single span roof with thick, deep arches that spring low from massive walls.

The roof of the BP filling station is the largest single span roof for a filling station in Europe.

Initial plans were for a two or three span roof with the void between station and ground level filled with spoil from tunnelling on the St Pancras branch.

The church is built of flint to an unusual design, the nave and north aisle having been given a single span roof with king-posts resting on the arcade, probably in the 15th century.

To avoid the foundations of the roof interfering with the space beneath, and to simplify the design, and minimise cost, it was decided to construct a single span roof, with cross ties for the arch at the station level.

This led to the ability to span roofs with stone vaulting at an early date - a field in which England led the way - and, also, to provide a sound basis for supporting a massive central tower which, in later times, also carried a spire.
