Home additions and extensions are the most significant renovation projects a New Brunswick homeowner can undertake, literally expanding the footprint of the home to add bedrooms, living space, in-law suites, garages, or second storeys.
In NB's real estate market, where the cost of a new home build continues to rise, adding to an existing property is often more cost-effective than buying or building new — particularly in established Fredericton, Moncton, and Saint John neighbourhoods where lot availability is limited.
NB additions must be designed to integrate seamlessly with the existing structure's foundation, framing, roofing, siding, and mechanical systems, while meeting current NB Building Code requirements for insulation (minimum R-24 walls, R-50 attic), structural loads including NB's significant snow and wind loads, and foundation frost depth requirements of 48 inches minimum.
What's Included
- Ground-floor additions with new foundation, framing, roofing, and exterior finishing
- Second-storey additions with structural reinforcement of existing walls and foundation
- Bump-out extensions for kitchens, bedrooms, and bathrooms (8-15 feet)
- In-law suite and multi-generational living additions with separate entrance
- Attached garage conversions and new garage construction
- Foundation work to NB frost depth requirements (48" minimum below grade)
- Structural engineering for NB snow loads (up to 3.5 kPa) and wind loads
- Exterior matching — siding, roofing, windows, and trim to blend with existing home
- Full mechanical integration — HVAC, electrical, and plumbing tied into existing systems
- NB Building Code compliance including energy efficiency, fire safety, and accessibility
