Additions and Extensions
Sometimes your dream home just needs more room to grow. At Altevita, we specialize in designing and building custom home additions and extensions that give you the extra space you need—without the stress of moving. Whether it’s a second-story addition, a kitchen expansion, or a sun-filled family room, our team handles every detail from design to construction with care, precision, and transparency.
Why Choose a Home Addition?
Home additions are one of the most practical ways to expand your living space while boosting your property’s value. Instead of uprooting your family, you can create a home that fits your evolving lifestyle:
More Space for Growing Families – Add bedrooms, bathrooms, or an in-law suite.
Better Functionality – Expand kitchens, living rooms, and storage.
Luxury Upgrades – Create a sunroom, home office, or spa-like ensuite.
Higher Home Value – Thoughtfully designed additions make your property more desirable on the market.

The Altevita Home Addition Process
We start with a detailed conversation to understand your goals, budget, and design vision. This ensures we recommend the best type of addition for your lifestyle.
Our team prepares preliminary drawings and a transparent cost estimate. We refine the design together until it perfectly matches your needs.
We take care of all zoning, by-law checks, and building permits. This saves you stress and ensures the project complies with local regulations.
Our experienced tradespeople build your addition with care and precision. We manage timelines closely, keep the site safe, and minimize disruption to your home.
Once complete, we review the new addition with you in detail. Any final adjustments are made so you can move in with complete confidence.
