# Building areas for specs and drawings

> Multi-building projects can now partition specifications and drawings into per-building areas, so the same section and sheet numbers can coexist across buildings without colliding.

Projects with multiple buildings often ship a spec book and drawing set per building, with the same section and sheet numbers repeated in each. Specset now supports building areas to keep them straight.

- **Per-building namespaces.** Assign an area to each spec or drawing file, and every extracted section and sheet inherits it. Section 09 91 23 in Building A and Building B are now two distinct records.
- **Grouped browsing.** The specifications list groups by area and then division, so each building reads as its own spec book.
- **Area-aware answers.** Search, Q&A, and reviews understand areas, disambiguate duplicate numbers, and can be scoped to a single building.

Areas are opt-in per project under project settings. Read more in [Specifications](https://docs.specset.com/docs/source-of-truth) and [Drawings](https://docs.specset.com/docs/plan-sets).
