What this detail covers
- A standard internal timber frame corner build-up (plan view).
- Ensuring there is backing where linings and sheathing need support.
Key steps
- Form the corner with the specified stud/cripple arrangement.
- Install sheathing as required (external wall OSB/3 or other specified layer).
- Fix to schedule and keep the corner square to avoid cumulative layout drift.
Checks
- Corner is square and studs are at the specified centres.
- Adequate backing exists for linings/boards at the corner.
Common mistakes
- Under-providing backing at the corner, creating weak fixing for linings.
- Corner built “mirror image” from drawings, affecting later details.
Indicative only: always follow the engineer’s fixing schedule and the project drawings.
