Exterior renovation

Montreal’s South Shore

Love your neighborhood but feel like your home is running out of space? Discover this stunning home addition project in the Ahuntsic area of Montreal. With our residential expansion expertise and turnkey construction services, you can transform your home without giving up the community you love.

A Design That Blends Seamlessly with the Existing Structure

Our clients wanted to enjoy the peaceful charm of their neighborhood while gaining extra living space in their single-family home. Our team of designers and architects created a rear extension with a rooftop terrace accessible directly from the second floor.

Before construction began, we took care of all administrative steps, including securing permits and ensuring full compliance with municipal regulations.

Construction Highlights

Here’s a breakdown of the key phases of the project:

  • Partial demolition of the rear entryway, basement access, and outdoor staircase
  • Excavation, foundation work, and concrete slab pouring
  • Framing of the new structure: walls and roofing
  • Exterior siding using engineered wood (CanExel) for durability and low maintenance
  • Installation of energy-efficient casement windows
  • Complete electrical installation and interior finishing
  • Rooftop terrace with concrete slab and stainless steel railings
  • New spiral exterior staircase and adjacent balcony extension
