Our Addition Framing Services In Milton

Second-Floor Addition Framing
Complete structural framing for second-floor additions — including new floor systems, load-bearing walls, roof framing, and structural tie-ins to your existing home. In Milton, many homeowners in newer subdivisions purchased single-storey or 1.5-storey homes that no longer fit their family size. Second-floor addition framing in Milton provides the space without the move.
The existing foundation and first-floor framing must support the new load. Timberr Framing assesses the full scope and frames to engineered specifications.

Rear Addition Framing
Rear additions are a popular choice for Milton homeowners looking to expand kitchens, add family rooms, or create open-concept main floors. We frame rear bump-outs, kitchen extensions, and full-width rear builds — all properly tied into your existing structure.
All rear addition framing in Milton is completed to Ontario Building Code with clean, solid tie-ins to the original frame.

Side Addition Framing
Side additions extend into your side yard to gain additional living space. In Milton's newer subdivisions, lot widths vary — side additions require careful planning around setback requirements and neighbouring properties.
Timberr Framing handles the structural framing for side additions across Milton — whether the lot is compact or generous.

Garage Conversion & Addition Framing
Converting an existing garage into living space or building a new attached garage addition requires structural framing that meets code. Milton families often convert garages to create home offices, playrooms, or secondary suites — especially in areas where the garage footprint offers the easiest path to additional square footage.
We frame garage-to-suite conversions, garage additions with second-floor living space, and standalone garage structures. All work is inspection-ready.

In-Law Suite & Secondary Suite Framing
In-law suites are in growing demand across Milton as multi-generational families look for housing solutions under one roof. Whether you are building a basement suite, a ground-floor addition, or a second-floor unit, the framing must meet Ontario Building Code requirements for separate dwelling units — including fire separation, egress, and sound isolation framing.
Timberr Framing understands the code requirements for secondary suites and frames every element to spec.

Frequently Asked Questions — Home Addition Framing Milton
How much does home addition framing cost in Milton?
Addition framing costs in Milton depend on the type of addition, total square footage, and structural complexity.
A rear addition frame is generally the most straightforward option. Second-floor additions cost more because the existing foundation and first floor must carry the new load — on some newer Milton subdivision homes, this is simpler than on older structures, but it still requires proper engineering.
Garage conversions and in-law suites vary depending on the scope of structural work required.

How long does addition framing take?
Timeline depends on scope. A standard rear addition frame typically takes one to two weeks. A full second-floor addition takes two to four weeks depending on size and structural requirements.
Timberr Framing provides a clear project schedule during the quoting process and maintains open communication from start to handoff.
Do I need a structural engineer?
In most cases, yes. Any addition involving load-bearing changes, new foundation work, or a second-floor build requires structural engineering. The Town of Milton requires engineered drawings as part of the building permit process.
Timberr Framing coordinates directly with structural engineers and frames to their specifications throughout the project.
Can you tie a new addition into my existing home?
Yes — this is one of the most important aspects of any addition project. A poor structural tie-in leads to settling, water intrusion, and costly corrections down the road.
Timberr Framing specializes in structural tie-ins between new additions and existing Milton homes. We assess the existing framing, identify load paths, and connect the new structure properly — whether it is a rear bump-out, a side extension, or a full second floor.
Do I need a building permit for framing?
Yes. Any home addition in Milton requires a building permit from the Town of Milton before construction can begin. This applies to second-floor additions, rear additions, side additions, garage conversions, and in-law suites.
Timberr Framing builds every addition to Ontario Building Code and ensures all framing is inspection-ready at handoff.
Do you work with builders and general contractors?
Yes. Timberr Framing regularly works as a framing subcontractor for general contractors managing home addition projects in Milton.
