Structural questions belong early in design, especially for large openings, additional floors or changing loads.
What the drawing needs to explain
Create a phase drawing with three colours: repair now, improve later and investigate first. Mark where phases meet, such as roof edges, service routes and finished floors.
Collect existing information
Plans, earlier calculations and photographs help establish the starting point. Identify missing information and necessary site investigations.
Avoid untested assumptions
An opening on a sketch is not yet a buildable solution. Early advice can show implications for beams, bearings, foundations and layout.
Keep documents aligned
After design changes, calculations and drawings must still match. Discuss construction assumptions with the people carrying out the work.
Decide this before construction
Address assessed causes of defects before new finishes conceal them. Plan comfort measures together with ventilation and necessary access to building services.
Which trade-off matters?
A complete approach can improve coordination, while phased work spreads the budget. Compare which junctions would need reworking after a delay and which elements can be completed independently.
Questions for your own property
- What changes the load path?
- What records exist?
- Do the drawings and calculations match?
