What Full General Contracting Means for Hamilton Home Additions
A home addition touches every trade. Structural framing, foundation work, load-bearing walls and beams, insulation, drywall, flooring, trim, doors, and windows are all within our scope. Beyond the carpentry, we coordinate licensed electricians and plumbers for the rough-in work, and HVAC when the project requires it. We've built additions across Hamilton and handled the complex versions of all of it.

Most contractors handle one part and expect you to manage the rest. We take care of the full build. One point of contact, one team accountable from the first footing to the last coat of paint. We can also help you figure out what approach makes sense for your space and your budget before you commit to anything.
Types of Home Additions We Build in Hamilton
Second storey additions
Adding a full second floor changes the entire footprint of what your Hamilton home can offer. It's a substantial project, but it's often the most cost-effective way to significantly increase your living space without changing your lot size or your address.
Lateral extensions
Building outward from the existing structure, off the back or off the side. Works well for expanding a main floor, adding a primary suite, creating a larger kitchen, or opening up space that feels too tight in its current footprint.
In-law and granny suites
A separate living space for aging parents or extended family, with its own entrance, kitchen, and bathroom. This can be a conversion of existing square footage or a new addition built onto the structure. We'll walk you through both approaches and what each one actually involves.

How a Hamilton Home Addition Project Unfolds
Before we quote anything, we visit the property and look at the existing structure. That tells us what the addition can realistically look like and what it's going to take structurally to get there. From there, we handle permits — Hamilton's building department has specific requirements for additions and we know them well. We don't break ground until everything is approved.
Once the build starts, the sequence is structure first, trades next, finishes last. Framing and structural work, then rough electrical and plumbing, then insulation, drywall, flooring, and everything through to the finished product. One continuous build with one team accountable for all of it.

Get A Free EstimateFrequently Asked Questions About Home Additions in Hamilton
Do I need a permit for a home addition in Hamilton?
Yes. Virtually all home additions require a building permit in Hamilton. This applies to second storeys, lateral extensions, and most in-law suite builds. We'll tell you what's required for your project and work through the permitting process before we break ground.
How long does a home addition take?
It depends on the scope. A lateral extension can take 2 to 3 months. A full second storey is typically 4 to 6 months. You'll get a realistic timeline at the estimate stage, and we'll keep you updated throughout the build.
Can you help with the design of the addition?
Yes. We can help you think through what makes sense for your space and your budget before anything gets drawn up. For additions that require engineering drawings, we can point you in the right direction. Either way, you'll get honest input before you commit to anything.
What trades are included in your scope of work?
We coordinate the full build. Structural framing, carpentry, windows, doors, drywall, insulation, flooring, and trim are all part of what we take to completion. For electrical, plumbing, and HVAC, we bring in licensed trades as the project requires.
Can you build an addition while we're living in the house?
In most cases, yes. We structure the build to minimise disruption to the occupied portions of the home. There will be phases with more noise and dust — particularly during structural work — and we'll walk you through what to expect at each stage before the build starts.
