Design and construction

Coordinated from the inside out.

The narrow footprint and zero-lot-line condition shaped the structure, servicing strategy and construction sequence.

  • Nail-laminated timber (NLT) selected for its suitability and construction speed.
  • Steel bracing at the rear stabilizes the slender building.
  • Mechanical and support spaces integrated into the first floor because there is no basement.
  • Prefabricated components required close coordination with panel fabricators.
  • Construction proceeded from the inside out, with carefully coordinated sequencing.
  • Drawing packages were issued in phases to support rapid housing deadlines.
