We Converted Our Cold Sunroom Into a Year-Round Home Office

Working from home changed everything about how I think about our house. The sunroom we'd ignored for years suddenly became the most important room — except it had single-pane windows, no insulation, and no heat source.

I found Trillium Renovations through NeedReno after posting a project for a sunroom conversion. Their approach was practical: instead of ripping everything out, they assessed what was worth keeping and built a thermal upgrade plan around it.

The scope ended up being: spray foam insulation in the ceiling and under the subfloor, triple-glazed windows to replace the original single-panes, a wall-mounted electric heater (zoned separately from the main house), and new Hardie Board siding on the exterior wall to replace the rotting wood.

The total came to $28,400. They completed it in nine days over two weeks (waiting for window delivery between weeks one and two).

The transformation is remarkable. On a -20°C day last January, the room was comfortable in a light sweater with the heater on low. Natural light all day. I put my desk facing the backyard and I genuinely look forward to sitting down to work.

I've recommended NeedReno to four of my colleagues who are doing home office renovations. The process of getting matched with qualified contractors is so much less stressful than cold-calling people on Google.
