Our Addition Services

Second-Storey Addition
You need more bedrooms, but your lot doesn’t allow you to expand outward. A second-storey addition is the most effective solution for doubling your floor space without encroaching on your yard.
Bois-X assesses the load-bearing capacity of your existing structure before any work begins, and integrates the new storey in a way that is consistent with the architecture of your Montreal property.
Ground-Floor Extension
A kitchen that’s too narrow, a living room that no longer suits your family: a lateral extension solves these problems for good. This type of project expands your living space while preserving the existing interior configuration.
Our teams manage the permit process, foundation work, and finishing integration for a seamless result, from floor to ceiling.
Garage Conversion
An unused garage often represents several dozen square metres of untapped space. Converting it into an office, a bedroom, or a family room is one of the most cost-effective projects in terms of added value to your property.
Bois-X carries out this type of conversion in Saint-Leonard and throughout the greater Montreal area, ensuring insulation, ventilation, and compliance with building codes.
Structural Reinforcement and Modifications
Some home addition projects require work on the existing load-bearing structure: removing load-bearing walls, reinforcing beams, or modifying foundations. This work demands precise technical expertise.
Bois-X has the carpentry and joinery training and the RBQ licence required to work on the structure of your building in full compliance, in Laval as in Montreal.
