13 — Behind the rooms
A good design only helps if the builder, cabinetmaker, electrician and tiler can build it without guessing. Design documentation turns decisions made room by room into drawings, schedules and specifications that trades can price, order and install from.
Every project needs a different mix. A single kitchen may only need joinery elevations and a finishes schedule, while a whole-home renovation usually needs the full set. We scope the documents to the work, so nothing is drawn for the sake of it.
Walls, openings, clearances and furniture positions, based on the space planning decisions.
Cabinet heights, door and drawer layouts, shelving, handles and material callouts for kitchens, vanities, wardrobes and built-ins.
Fitting positions, switching, power points and feature lighting, drawn so the electrician can set out each room before plastering.
Room-by-room lists of paint, tile, stone, flooring, tapware and hardware, with product names and where each one goes.
Set-out drawings for wet areas and splashbacks, plus written notes on grout colours, niches and edge finishes.
A furnished floor plan showing bedrooms, wet areas, the open-plan kitchen and living areas, the kind of drawing a documentation set builds on.
Documentation matters most when several people need to build from the same design decisions.
Builder specifications often leave interiors vague. Clear documents let you compare quotes on the same scope and lock in lighting, joinery and finishes before construction reaches them. See New Build Interior Design.
Renovations involve several trades working in an existing house. A shared set of drawings keeps the plumber, cabinetmaker and tiler working to the same dimensions. See Home Renovation Design.
Built-in cabinetry is made to measure, so small errors are costly. Detailed elevations give the cabinetmaker exactly what to build. See Custom Joinery Design.
Documentation is the last design stage, not a separate job. It records choices already made. The full sequence is set out on our design process page.
Step 1
We review the plans, measure the rooms and agree on which drawings and schedules the project needs.
Step 2
Layouts, colours and materials and lighting and finishes are signed off so the drawings can reflect them.
Step 3
Plans, elevations and schedules are prepared together and checked against each other, so a tile on the schedule matches the tile on the drawing.
Step 4
You receive a clear set to share for pricing and construction, with questions from trades answered against the same documents.
No. Architectural and engineering drawings cover structure and building approvals. Interior documentation sits alongside them and covers what the rooms contain: joinery, lighting positions, finishes and fixtures.
Yes. A kitchen or bathroom can be documented on its own, as long as the design decisions for that room are resolved first.
When every builder prices the same schedule, quotes can be compared fairly, and there are fewer allowances left open to change later. Our journal article on what affects interior design costs explains more.
Ideally before the build contract is finalised, so lighting and joinery are included from the start. Read New Build Interior Design: What to Plan Early.
