A hammer-beam is a form of timber roof truss, allowing a hammerbeam roof to span greater than the length of any individual piece of timber.In place of a normal tie beam spanning the entire width of the roof, short beams – the hammer beams – are supported by curved braces from the wall, and hammer posts or arch-braces are built on top to support the rafters and typically a collar beam.
The hammerbeam roof was the culmination of the development of the arch-braced truss, allowing greater spaces to be spanned. The hammerbeam roof of Westminster Hall in London, designed by Hugh Herland and installed between 1395 and 1399, was the largest timber-roofed space in medieval Europe, spanning a distance of just over 20 metres (66 ft ...

A simple timber frame made of straight vertical and horizontal pieces with a common rafter roof without purlins. The term box frame is not well defined and has been used for any kind of framing (with the usual exception of cruck framing). The distinction presented here is that the roof load is carried by the exterior walls.
Section view through a house roof drawing showing names for parts of the structure. [clarification needed] (UK and Australia). Ctrs. means centers, a typical line to which carpenters layout framing. Domestic roof construction is the framing and roof covering which is found on most detached houses in cold and temperate climates. [1]
The roof shown in the MAFF leaflet is a telescoping cover, with internal dimensions of 18 + 3 ⁄ 4 in (480 mm), meaning a relatively loose fit over the topmost box. The total height of the roof is (depending on timber thickness) around 6 + 1 ⁄ 4 in (160 mm), though a 4 in (100 mm) roof is now also common.
