Infill on a tight street
A gap between two older houses on a city street is often too narrow for a timber frame crew to lay out panels and too valuable to leave empty. A block shell suits it: the walls go up course by course from a single scaffold, the material arrives on pallets a lorry can crane over the pavement, and the finished wall resists fire and sound from the neighbours better than a light frame does without extra layers.
The house is 12 m (39 ft) deep and 7 m (23 ft) across, two storeys of 2.8 m (9 ft 2 in), with two partitions on each floor running the short way to make front, middle and back rooms.
Two storeys of block, counted storey by storey
Each floor's walls are their own group in the list, so the block, grout, bond-beam and rebar rows appear once for the ground floor and once for the upper floor. That matches how the work is called off: the first lift of block to the first floor bond beam, then the floor goes on, then the second lift. Each storey's bond beam runs the full length of its walls, over the openings as well, while the stretcher rows take the doors and windows off at the height they actually occupy.
The control joint row works wall by wall: a joint every twice the wall's height, capped at the takeoff's limit, along each straight run. Joints at changes of height and beside openings are extra and come from the masonry drawings.
Roof and foundation
A 6 in 12 shingle roof spans the 7 m width from eave to eave, with short 300 mm (about 12 in) eaves to stay inside the lot line. No ice-dam strip: the count is 0. The strip footing under the outside walls is 600 mm (2 ft) wide in a trench 0.9 m (3 ft) deep; a party wall on the boundary would need a footing designed with the neighbour's in mind, which this page does not attempt.
Outside this list
The upper floor structure, the stair, the render or brick slip on the street face, lintels, and the vertical reinforcement and grouted cells a two-storey block wall may need are design matters for the engineer and are not counted. Craneage and pavement licences are the job's logistics, not quantities.
