Architectural drawings can be intimidating. They're technical documents, full of symbols, abbreviations, and conventions that make immediate sense to a designer and almost no sense to anyone else. But understanding your plans is important — they're the specification for the home you're about to spend a significant amount of money building.

Here's a plain-English guide to what you're looking at.

The Site Plan

The site plan shows your block from above, with the proposed building footprint positioned on it. This drawing tells you:

• Where the building sits on the block

• The setbacks from each boundary

• Driveway and path locations

• Relationship to neighbouring buildings

If you're trying to understand how private your outdoor areas will feel, or whether the neighbour's upper floor will overlook your living room, this is the drawing to study.

The Floor Plan

The floor plan is the drawing most people are familiar with — a cut-through view of the home from above, showing walls, doors, windows, and room names. Key things to look for:

• Room dimensions — are they what you agreed? Measure them against your existing furniture if you're unsure

• Door swings — are they shown? A door that swings the wrong way can create real daily frustration

• Window locations — do they provide privacy from the street or from neighbours? Is there natural light in the right places?

• Traffic flow — can you move through the home without passing through private spaces to reach common ones?

The Elevations

Elevations show the exterior of the building from each side — front, rear, and each side. This is your view of what the home will look like from the street and from the garden. Check:

• Roof pitch and form

• Window proportions and placement

• Cladding materials and how they change across the facade

• Eave depth — this tells you a lot about the passive design approach

The Sections

A section is like a slice through the building — you're looking at the interior of the home as if a wall has been removed. Sections show ceiling heights, the relationship between floors in a multi-storey home, and the profile of raked or vaulted ceilings. If you've been promised a raked ceiling in the living room, check the section to understand exactly what you're getting.

Schedules and Specifications

Attached to the drawings are usually schedules — lists of doors, windows, finishes, and fixtures with codes that reference back to the plans. These documents are where a lot of the cost lives. Make sure you understand what's been specified and whether it matches your expectations.

Reading your plans is worth the effort. The more you understand them, the better the conversations you'll have with your design and build team — and the more likely the finished home is to be exactly what you imagined.
