Every sheet states its scale
Without a scale a drawing is just a picture. The plan is placed at 1:20, 1:50, 1:100 or 1:200, whichever is the largest that fits the sheet. You will never see an odd 1:73, so you can measure the printout with a ruler.
The measured plan labels each wall's length in centimetres, and a wall shared by two rooms is labelled once. Separate sheets show the furniture layout with item numbers, the electrical plan and the finishes plan.
Elevations show each wall as the builder sees it
An elevation shows openings, furniture against the wall, and sockets and switches at their real heights. A shared wall gets two elevations, one per side, because finishes and sockets differ. Empty walls are left out by default.
One area figure everywhere
The room schedule lists each room's number, floor area, height and wall area for finishing, plus the total and living area. Balconies get their own line and stay out of the total.
Wall area is perimeter times height minus windows and doors. Take a 3 x 4 m bedroom with a 2.7 m ceiling. The 14 m perimeter gives 37.8 m², a 1.5 x 1.5 m window and a 0.8 x 2.1 m door take away 3.9 m², leaving 33.9 m². The editor and the estimate use the same figure, so plaster quantities from the album and the estimate match.
A schedule of works without prices, on purpose
This sheet lists quantities only. Priming, plastering and painting walls in square metres, likewise screed and flooring; skirting and reveals in running metres; doors and electrical points by count, plus chases and cable. Rate and total columns are left blank, because rates depend on the region, the site and the contractor.
Furniture gets its own schedule with sizes in centimetres, and so do electrics and openings, with sizes and sill heights.
The album also does tiles and the breaker panel
If a wall or floor is tiled, the album lays it out: whole and cut tiles, the total with 10 % spare, area and grout length. Whole tiles start from the floor and the near corner, cut ones go to the top and the far edge, which leaves the fewest offcuts.
The breaker panel sheet lists circuits, breakers and cable sizes. And the title page carries a QR code. Point a phone at it, and the 3D tour of the apartment opens.
