The base or plinth of a building, often expressed as a horizontal plane extending beyond the building’s structure.
Post and beam
A system of timber construction making use of a regular framework of slender vertical columns and horizontal beams, the spaces on the exterior often being filled with sheets of glass or wooden cladding.

A system heating often used for in-floor heating, where tubes are cast into the concrete floor slab into which hot water is pumped to warm the floor.
