Expand Your Outdoor Space

Most backyards sit half-empty because the footprint stops too soon. A Home Additions deck or covered patio pushes that boundary out and turns a cramped patch of grass into a real outdoor room. People spread out and stay longer when you have the space.

We start every project by mapping how wind, sun, and lot contours in Metro Vancouver shape your space. That way the new build feels like an original piece of the home, not a box tacked onto the back wall. The result flows straight from the sliding door onto durable cedar, composite, or treated-lumber decking built for wet winters and honest use.

Serving Government Road Area

The same kind of addition shows up differently on a Burnaby slope, especially in neighbourhoods like Government Road where retaining walls and drainage need careful thought before a single post goes in. Paragon Exteriors works with homeowners there to design decks and covered extensions that handle the grade without disrupting the yard below.

Strata and permit rules along the road can catch people off guard, so we handle the paperwork from day one to keep the build moving. Local knowledge means a home addition arrives on time and fits what the property allows, not a generic plan that stalls at city hall.

Framing and Materials

The frame starts with pressure-treated posts set in concrete footings below the frost line. Beams use doubled 2x material, sized to span the space between posts without sagging. Joists run perpendicular and are hung with galvanized metal connectors that resist corrosion in Metro Vancouver’s damp climate.

Decking options include clear western red cedar, capped composite boards that resist fading, and pressure-treated lumber that takes stain well. Composite decking uses hidden fasteners for a clean look, while cedar and treated wood are face-screwed with coated deck screws to prevent rust streaks.

Water Management and Load Paths

Where an addition connects to the house, the ledger board is bolted through the existing rim joist and sealed with continuous Z-flashing tucked behind the siding. This flashing directs water away from the ledger, preventing rot at the wall. A gap between the siding and the deck framing allows air to dry any moisture.

For covered additions, the roof structure connects to the house with a similar flashing detail and uses independent footings to support the load, avoiding stress on the existing wall. The deck surface slopes away from the house, and gaps between boards let rain drain straight down so water never pools against the structure.

Bylaw Requirements for Additions

In the City of Vancouver, the Vancouver Building By-law No. 12511 requires a building permit for any addition or change to a building. This includes adding new floor space, decks, or enclosed porches. You must get this permit before starting work to meet safety and building standards.

In Surrey, the Noise Control By-law, 1982, No. 7044 allows construction noise for home additions only from Monday to Saturday, between 7:00 a.m. and 10:00 p.m. Homeowners can do quiet work on Sundays, but professional contractors cannot.

In Burnaby, the Noise or Sound Abatement Bylaw 1979, No. 7332 limits construction for home additions to weekdays from 7:00 a.m. to 8:00 p.m. and Saturdays from 9:00 a.m. to 8:00 p.m. No work is allowed on Sundays or holidays. Continuous noise from construction must not go over 85 dBA, measured at least 15.2 m from the source in residential areas.

Community Projects

One example of the work this team can handle is a local school that had problems with water getting in because a walkway and stairs had pulled away from the buildings. To fix this, the crew rebuilt the walkway and stairs as an exterior addition. They added new doors and siding while working around the school day to keep student paths clear. Now, the school has a dry and stable connection between buildings, which removes worries about water damage and unsafe access.
