04 — Home Additions
More house, without moving house
Rear extensions, second storeys, mudrooms and garages that read as though they were always part of the home.

The approach
Home Additions done properly
An addition is the most complex thing we build: foundations, structure, envelope, roofline and the delicate work of tying new to old so the seam disappears. Decades of Ottawa builds mean we know how those transitions behave over time.
Seamless transitions
Rooflines, siding, floor heights and trim matched so nobody can point to where the original house ended.
Full project management
Architects, engineers, city approvals and trades coordinated under one point of contact.
Built to last generations
Proper footings, structural framing and a building envelope detailed for the long haul.

“My priorities were design, trust, communication and of course results. There were some hiccups along the way, but they were well explained to me and were all addressed. I was very pleased with the communication and responsiveness of the team and absolutely love how the renos turned out. I am glad I picked Magnolia and have no issues recommending them!”
“We converted a 3 bedroom single family home in Beaverbrook into our 5 bedroom forever dream home — a complete basement renovation with a theatre room, a bathroom with a walk-in shower and heated floor, and a guest suite. Thanks Magnolia, for bringing our dream home to life.”

“Joey (owner) and his team were amazing! They were professional, friendly, and best of all, they completed everything on time! They were also always willing to answer my millions of questions lol. The final product was exactly what I wanted. I would use Magnolia Construction for any home improvements in the future. I highly recommend them!”
