- In North America we use the imperial system, not the metric system, for construction 12″=1′.
- Wall studs are 16″ apart on center (OC).
- HVAC 20″x26″
- HWT 20″dia
- W/D 24″x28″
- 30″ clearance required in front of utility appliances (in case of needing repairs)
- 6″ clearance required around back and side of HVAC, HWT, W/D
- Laundry sinks adds $5000
- Utility rooms are placed near building core , not adjoining windows
- Wet rooms are place near the building core, not adjoining windows (to avoid freezing)
- Pipes are expensive. minimize distance by sharing wet walls for kitchen/ bathroom/utility.
- Bathroom should be accessible from main living area because the condo might be small enough for you to walk there from your bedroom.
- En suite master bathroom not recommended because it takes too much space and your friends will walk through your messy bedroom.
- Powder room (2pc) by front door if included.
Hallway, Door and Light Switch Considerations
- Minimize hallways because they are wasted space
- Light switch inside room (except closet ) on door handle side
- Doors open into room, against a wall if possible because space behind door is wasted
- No window in kitchen- you’ll need the upper cupboard space
- refrigerator cannot be beside the dishwasher or stove
- You need a coat closet by the front door
- Optimum depth for a closet with a sliding door is 18″
- Closet includes a 12″ deep shelf
- Hanger rails sits 2″ back from the front shelf
- Minimum width for a walk is closet with shelves on both sided is 18″+18″=30″ walkway
- Sliding door openings are typically 60″ wide
- Windows cannot be wider than 6′
- Optimal width for windows is 4′
- Windows must be more than 6″ from floor or ceiling
- Condo floors are poured concrete, so HVAC vents are in the walls under the windows
