Home Additions & Extensions in St. Albert
Expand your living space — beautifully, safely, and built to last.
When you love your home but need more space, a custom home addition is the perfect solution. At Frostline Renovations, we design and build seamless home extensions for homeowners across St. Albert, Edmonton, and surrounding areas — adding valuable square footage that blends perfectly with your existing home.
Whether you’re adding a new bedroom, expanding a kitchen, creating a sunroom, or building a full second story, our experienced team handles design, permits, framing, plumbing, electrical, and finishing — start to finish.
Why Build a Home Addition Instead of Moving?
In today’s Alberta housing market, expanding your home often makes more sense than selling.
Home additions allow you to:
- 🏡 Stay in the neighborhood you love
- 💰 Increase resale value with functional square footage
- 👨👩👧 Accommodate growing families or multi-generational living
- 💼 Add income potential with secondary suites or rental units
- 🌤️ Modernize your layout without the cost of a new build
Frostline Renovations helps you reimagine what’s possible — with expert planning, code-compliant construction, and finishes that make the new space look like it’s always been there.
Types of Home Additions We Build
We specialize in custom-designed additions tailored to your home’s structure and your goals.
1. Room & Main-Floor Additions
Expand your home’s footprint with new:
- Bedrooms or guest suites
- Expanded kitchens or dining areas
- Larger living rooms or family spaces
- Home offices and studies
- Accessible main-floor bathrooms or laundry
We match existing rooflines, siding, and finishes so your addition integrates seamlessly into your home’s architecture.
2. Second-Story Additions
Need space but can’t expand outward? Add it upward.
Our team designs and builds structurally sound second floors that add major square footage and long-term value.
We handle all engineering, load-bearing assessments, and city permits to ensure your new level meets Alberta Building Code requirements.
3. Garage Additions & Conversions
Add a new attached or detached garage, or convert your existing one into a living or hobby space.
Common projects include:
- Heated garage with workshop space
- Carriage suite or studio above the garage
- Converting a detached garage into an office or gym
4. Sunrooms, Four-Season Rooms & Enclosed Patios
Enjoy the outdoors year-round with a bright, insulated sunroom or four-season addition.
We use energy-efficient windows, in-floor heat, and durable framing built for Alberta’s winters — turning your patio into a cozy retreat or all-season family space.
5. Basement Extensions or Add-Unders
For homes on slopes or acreages, we can extend your foundation or partially excavate for basement-level living space.
This approach maximizes usable square footage without altering the home’s footprint above grade.
