Building conditions in Knysna
Knysna lies around a lagoon between indigenous forest and the sea, with steep slopes, rain throughout the year and damp air. Many sites need retaining walls, careful stormwater design and engineered foundations, and timber construction is common, using local and plantation wood. The 2017 fires made fire risk a real consideration, so fire-resistant materials and cleared zones around homes are worth discussing with a builder. Salt air and humidity affect steel and fixings near the water. Housing includes holiday homes, security estates such as Thesen Islands and Pezula, and township areas such as Hornlee. Knysna Municipality approves building plans, and rebuilding and renovation remain steady.

Typical house plans requests in the area come from:
- Coastal and holiday homes: seaside plans must deal with wind, coastal setbacks, steep sites and holiday-home layouts
- Security and lifestyle estates: estate homes need plans approved by the estate's design committee before council submission
- Homeowners: homeowners need plans for extensions, second storeys, garages and enclosed stoeps
- Guesthouses and lodges: guesthouses and lodges need plans for new rooms, conversions and fire and access compliance
- Township homes and backyard rooms: families need plans for backyard rooms, extensions and new homes on their own stands
- Smallholdings and farms: plot owners need plans for farmhouses, cottages, staff housing and large sheds
