A complete project, from structure to basement creation to rear extension
- We removed the back of the building to a depth of 10 feet as well as the floor of the ground floor.
- We reinforced the floor from above by forming 2 large structures that held the center beam of the floor from above.
- We then excavated the basement for 9 feet in order to have 8 finished feet.
- The focus was on the insulation and the vapour barrier.
- Fully waterproof building envelope.
- The ''R'' ratings specified in the APCHQ's technical reports are reached or exceeded on the entire building.
- Heat pump air exchanger.
- The result is this beautiful single family duplex.
