MULTIPLEX: Concepts

  • Desirable to look like a large,

single family detached house.

  • Embrace materials, colours and

styles of the neighbourhood.

  • 2/3rds to be 3 bedroom units,

1/3rd to be 2 bedroom units.

  • Each unit to have its own

separate entrance at ground level.

  • Maximize green space by

building two stories tall.

  • Consider alternate forms of

stacking units rather than traditional side-by-side method.

MULTIPLEX: Site Plan

  • Designed to fit on 2 – 33’x110’ lots

in an established neighbourhood.

  • Surface parking is provided off the

back lane.

  • Each unit has an entry facing the

street.

  • Unit 1 has it’s living room facing

  • Unit 2 – 2 Bedrooms

18’x46’ = 828 sf TOTAL = 828 sf

  • Unit 3 – 3 Bedrooms

1st = 18’x36’ = 648 sf 2nd = 36’x18’ = 648 sf TOTAL = 1296 sf

MULTIPLEX: Second Floor

  • Unit 1

36’x18’ = 648sf

  • Unit 3

36’x18’ = 648sf

  • Units 1 and 3
  • verlap Unit 2 on the

second floor in order for one to face the back yard and one the front.

  • Bedrooms are

separated from neighbouring unit by a double corridor.

  • Units have potential

to have a small deck

  • n the upper floor.

  • Unit 3

18’x36’ = 648sf

  • Group debated whether

to have a basement or not.

  • Plumbing lines up with

washrooms on main floor.

MULTIPLEX: Systems

  • To promote responsible use, provide

individually metered space heating and water heating equipment.

  • Use high efficiency equipment.
  • Use a fan coil to distribute the space heating

and ventilation air to each room.

  • Use an air to air heat exchanger for

ventilation air (esp. important where tobacco use is high). OR …

  • Take dollars that would go into a gas fired

heating system for each unit and use in the envelope (better insulation, air tightness, windows). Heating load could be substantially reduced and space heating could be covered by electric baseboards.
