Home Additions in Laval & Montréal

High-performance residential additions. At Constructa, we add square footage with intention, blending architectural precision with high-end craftsmanship to transform how you live. Whether you need more room for a growing family in Laval or a new living space in Montréal, our team designs an addition that fits your home and your life.

From the first sketch to the final coat of paint, we oversee every phase of your addition. We coordinate every detail — from permits to final inspections — for a smooth, professional, turnkey experience. Our commitment to precision means clear communication, attention to detail, and structural choices executed with the same care we would apply to our own homes.

An addition is a major investment in your quality of life. Since 2017, we have built our reputation on a simple promise: putting the homeowner first. We respect your vision and your budget, and we make sure nothing gets lost along the way — so your new space enriches your daily life and protects your home's value.
