Sunroom Addition in London

Sunroom Addition projects come in from all over London — some are a focused single-room job, some anchor a much larger renovation. Either way, describe what you have in mind and the quote is free.

Below is what this kind of project involves around London, and an honest look at what moves the price — no invented flat rates.

Southwestern Ontario around London carries a lot of older housing, and renovations here routinely open walls onto the past — dated wiring, plaster, and framing that predates modern spans — so good quotes carry honest contingency.

That local context matters for sunroom addition: London's signature yellow-brick century homes often carry original plaster, dated wiring, and old galvanized plumbing that should be priced into any major renovation.

London's housing runs from yellow-brick Victorians in Old North and Wortley Village to the ranches and sidesplits that filled Oakridge, Westmount, and the east end after the war. That mix means renovation work here is rarely cookie-cutter: heritage-minded kitchen and bath updates in century homes, full main-floor reconfigurations in post-war bungalows, and basement conversions near Western and Fanshawe aimed at student and rental income.

A lot of London projects start with good bones and dated layouts — closed-off kitchens, a single bathroom serving three bedrooms, unfinished basements with decent ceiling height. If you own one of them and have been sketching a better floor plan for years, tell us what you have in mind and we'll line up a free quote from renovation contractors who work in London every week.

• Parts of Old North, Wortley Village, and Woodfield fall within heritage conservation districts, so exterior changes there can need approvals beyond a standard building permit.
• London's signature yellow-brick century homes often carry original plaster, dated wiring, and old galvanized plumbing that should be priced into any major renovation.
• Post-war subdivisions across the east and south ends are full of bungalows well suited to open-plan conversions and basement apartments.

No two London homes are the same, so instead of a flat price, here's what actually shapes a sunroom addition quote:

• The age of the home — much of London's housing has been standing a long while, and what's found once walls open (wiring, plumbing, framing) is the honest wildcard in older-home renovations.
• Footprint and whether the room sits on piles or a full foundation
• Glazing area and specification, from standard double pane to triple-pane low-e
• Roof style — studio shed roof, gable, or glass roof panels
• Heating method for year-round rooms, from ducted extensions to a heat-pump head
• How the room connects to the house — through an existing door or a new structural opening
