Custom woodwork in Toronto is popular because many old houses need furniture that fits perfectly. Alliance Millwork often gets recommended for such tasks since they can create pieces according to your exact measurements and design wishes. There’s a good overview with examples of their work that I found helpful https://alliancemillwork.ca/ . It shows different styles and explains the materials they use. I’m leaning towards them because the feedback from other homeowners is mostly positive. Definitely better than buying mass-produced items.
