Built in London
A Building-Science Builder, Based in the City
Starlit Homes is a NetZero-certified custom home builder based at 216 Rectory St in London, Ontario. From our office in the city, we design and build custom homes on your lot, garden suites and ADUs, and deep-energy renovations for buyers across London and the surrounding region.
We're a building-science company first. Two principals run every project — Omar Fayoumi on planning, design, and building science, and Meho Burzic on construction, with 25+ years on site — and every home we hand over is blower-door tested. We guarantee 1.5 ACH50 or better on every home. Our portfolio average is 0.85.
Since 2018, that approach has carried us through 24+ projects and more than 68,000 square feet of high-performance construction, from compact bungalows to estate builds.

The Difference
Why London Buyers Choose a Building-Science Builder
Any builder can show you finishes. We show you measured performance — and put a guarantee behind it.
Verified Airtightness
Most builders quote a spec. We test every envelope with a blower door and hand you the number. The Ontario Building Code allows roughly 3.5 ACH50 — we guarantee 1.5 or better on every home, and our portfolio average is 0.85.
Healthier Indoor Air
Every home includes ERV ventilation with MERV-13 filtration and an active sub-slab radon mitigation system as standard, backed by 90-day post-occupancy radon testing. Filtered, balanced fresh air instead of whatever leaks through the walls.
Lower Operating Costs
Continuous R-30+ exterior insulation, triple-glazed windows, and hybrid heat pump systems mean the home needs far less energy to stay comfortable through a London winter — and your utility bills reflect it.

Common Questions
Building in London: FAQ
Do you build inside London city limits?
Yes. Our office is at 216 Rectory St in London, and we build custom homes, ADUs, and renovations on lots throughout the city, infill lots included. We also serve the surrounding towns, from Ilderton and Komoka to St. Thomas and Strathroy.
How much does it cost to build a custom home in London?
Industry estimates for custom builds in Southwestern Ontario typically land between $250 and $500+ per square foot, depending on the lot, the design, and the finish level. Treat any per-square-foot figure as a starting point to verify against real drawings. Our 2026 Building Science Guide explains where the money actually goes.
Read the 2026 Building Science GuideHow long does a custom build take?
Plan for roughly 12 to 18 months from first design meeting to move-in: a few months for design and permitting, then 8 to 12 months of construction for a typical custom home. Size, site conditions, and municipal approval timelines can move that window in either direction.
