Additions & Extensions

Sometimes you love where you live but you've outgrown the space. BFL Construction builds additions and extensions that feel like they were always part of the original home — not an afterthought bolted onto the side.

We handle every type of addition: second storey additions, single-storey bump-outs, attached garages, detached workshops, in-law suites, and sunroom conversions. Each project starts with a feasibility assessment — we evaluate your existing foundation, structure, and systems to determine the best approach before any design work begins.

Matching an addition to an existing home is both a structural and an aesthetic challenge. Our team ensures that rooflines, siding, windows, and interior finishes blend seamlessly. We also handle all the behind-the-scenes work: extending HVAC systems, upgrading electrical panels, rerouting plumbing, and ensuring the new space meets current building code.

In-law suites and secondary dwelling units are one of the fastest-growing segments of our work. Whether you're building above a garage, converting a basement, or adding a standalone unit, we know the zoning requirements and building code provisions specific to Simcoe County municipalities.
