Custom design. Local care. A room worth coming home to.
A Toronto sunroom starts with the house you already have: its rear elevation, available garden space and connection to the rooms you use most. We help you plan a brighter addition without choosing a footprint before the property has been reviewed.
Why Serene in Toronto
Unmatched durability and design in Ontario. Every four-season and three-season sunroom we build in Toronto uses the finest sunroom window, door and roof systems on the market, precision-manufactured by Living Space and installed white-glove by our own local team.
Toronto’s 2021 Census backgrounder describes a mix of detached houses, semi-detached houses, row houses and apartments. For a detached house, we review the rear wall and route into the garden. For a semi or row house, bring the survey and tell us about shared access before we settle on room width. An apartment or condominium enquiry needs an ownership and approval discussion first; a region listing does not mean every dwelling can accept an addition.
Toronto Building’s small-addition guide asks for existing and proposed buildings, property-line setbacks and zoning information such as coverage and height. That makes a measured site plan more useful than a rough garden estimate. We ask where bins, bicycles and equipment move through the property, where mature planting sits, and how much outdoor space you want to retain. A bigger window wall should still leave a practical route between the house and yard.
From about $50,000 (10×10); most custom rooms $75,000–$80,000+. Every room is custom-quoted.
In more depth
The municipal contact is Toronto Building. Its Small Residential Additions guide is the starting point for an attached sunroom addition, and its online submission service accepts the application. We handle the permit and coordinate the drawings with the proposal. Tell us about previous additions or enclosed porches so the existing layout can be represented accurately.
For your Toronto design review, bring photos showing the rear of the house and the buildings beside it. We consider neighbouring shade alongside the room’s orientation, roof connection and intended winter use. Ask us to compare a Cathedral or Studio roof in the 3D design before choosing ceiling height.
