Most clients see their architectural drawings for the first time and nod along without really reading them — the lines and symbols look technical, and it’s easy to assume the details will sort themselves out on-site. They won’t. A drawing you don’t understand is a decision you’re making blind. Here’s how to actually read one before construction starts.
Start With the Floor Plan
The floor plan is the top-down view of each level — walls, doors, windows, and room labels. Walk through it room by room and picture yourself standing inside: where does the sun come in, how far is the kitchen from the dining area, does the bedroom door open into usable space or straight into a wardrobe. Room dimensions are usually marked in feet or meters along the walls — use them to picture actual scale, not just proportion on paper.
Check the Elevations
Elevations show what the building looks like from outside — front, back, and sides. This is where you confirm the building’s height, window placement on each facade, roof lines, and overall exterior style. If the floor plan is the “what,” the elevation is the “how it looks.”
Understand the Sections
A section is a vertical slice through the building, showing floor-to-floor heights, staircase design, and how different levels connect. This is where ceiling heights and any double-height spaces become clear — details that are easy to miss on a floor plan alone.
Look for These Details Specifically
Door and window swing directions. Arcs on the plan show which way doors and windows open — check these don’t block furniture placement or walkways.
Electrical and plumbing points. Switch, socket, and fixture locations are usually on separate layout drawings. Confirm these match how you’ll actually use each room before walls are finished — moving a point later is a change order.
Furniture layout, if provided. Some drawings include suggested furniture placement — a useful way to sanity-check whether a room’s real-world dimensions work for your needs.
Scale and north direction. The scale tells you how to convert drawing measurements to real dimensions, and the north arrow tells you which rooms get morning versus afternoon sun.
Questions Worth Asking Your Architect
What does this symbol mean? Can you show me this room’s actual size compared to a room I already know? What happens at this junction where two walls meet at an angle? A good architect expects these questions — asking them before construction starts is far cheaper than discovering the answer once the walls are up.
Why This Matters Before You Approve Drawings
Changes made on paper cost nothing. The same changes made after foundation work or brickwork has started cost real money and real time. Reading your drawings carefully — and asking questions until they make sense — is the cheapest quality control step in the entire project.

Frequently Asked Questions
What should I check first in a set of architectural drawings?
Start with the floor plan, it's the easiest to read and sets up understanding the elevations and sections that follow.
What's the difference between elevations and sections?
Elevations show the building's exterior faces, sections cut through the building to show internal heights and construction layers.
Why does reviewing drawings carefully matter before approval?
Once drawings are approved, changes become more costly and time-consuming, catching issues at this stage is far cheaper than during construction.
