What follows is the practical detail: how rear extension typically plays out on Peterborough homes, and the things that push a quote up or down.

Around Peterborough you get a mix of year-round homes and seasonal or waterfront properties, and renovation planning follows suit — off-season timing for cottage projects, access logistics, and materials chosen for four hard seasons.

That local context matters for rear extension: Parts of downtown Peterborough lie within the Jackson Creek floodplain, where Otonabee Conservation regulates development.

Brick is the default in older Peterborough — solid two-storey Victorians in the Avenues, worker-built homes in East City, and generous Edwardians near the downtown churches. These houses take renovation well: floor plans open up, attics become bedrooms, and basements add real living space once properly finished. Local trades have deep experience with century-home quirks, from plaster walls to balloon framing.

Trent University and Fleming College sustain demand for well-executed rental conversions, while families arriving from pricier markets fuel whole-house updates. Jackson Creek and the Otonabee River shape the map — some central blocks sit in regulated floodplain — so early permit conversations pay off. Describe your Peterborough project and we'll arrange a free quote from renovation contractors working locally.

• Parts of downtown Peterborough lie within the Jackson Creek floodplain, where Otonabee Conservation regulates development.
• Much of the central housing stock is pre-1930 brick, so knob-and-tube wiring and balloon framing turn up during major renovations.
• Student rental demand from Trent University and Fleming College keeps legal unit conversions among the most common projects.

No two Peterborough homes are the same, so instead of a flat price, here's what actually shapes a rear extension quote:

• Depth and width of the extension and the roof design over it
• Foundation choice — full basement extension, crawl space, or slab
• Whether the property is year-round or seasonal — access, water systems and timing the project around how you use the place all matter near Peterborough.
• Whether the kitchen moves into the new space, which adds services and finishes
• Grade and drainage conditions at the rear of the lot
• Minor variance requirements on tight lots
