What we do

One team for the whole timber scope, from the first sketch to the day the frame goes up.

Traditional timber frame

Full timber framed houses built with traditional mortise-and-tenon joinery. Strong, and unmistakably handcrafted.

Post & beam and glulam

Post and beam construction and glulam structures, with a variety of species and finish options to suit the building and the budget.

Log buildings

Log homes and buildings, plus the architectural timber details that give a conventional build its character.

Design & engineering

Preliminary design in 3D, and engineers who specialize in heavy timber construction and traditional joinery, so engineering is covered without compromising the details.

Structural Insulated Panels

Structural insulated panels close in the frame fast, creating a tight, highly insulated building that is efficient to heat and cool.

Restoration & repair

Log maintenance, structural timber repair, and restoration for existing log and timber buildings across Ontario.

Step 01

Design & budget

We start with your vision: how the space will be used, the styles you love, and the budget you’re working with. Then we develop a preliminary design in 3D modelling software and refine the concept with you until it’s right.

Prefabrication

Once the design is complete, prefabrication begins in our shop. Each component is carefully selected, laid out, cut, and finished, with a variety of species and finishes for you to choose from.

Installation

The prefabricated components ship to your site, ready for installation. Our crew raises the frame with the help of a crane. All joinery is secured with traditional wooden fasteners, for strength and for the classic look of traditional timber work.

Building envelope

We offer SIP installation to close in your log or timber home. SIPs install efficiently and create a tightly sealed, highly insulated building with outstanding energy performance. When our work is complete, your structure is ready for windows, doors, and finishes.

Quality, craftsmanship, and service.

When you call Mufferaw, you talk directly to the team behind the work. Every frame we cut, raise, and finish has to meet our own exacting standards.

Questions during installation? Our experienced team is available with guidance, resources, and additional labour if you need it.

For architects

Early collaboration with timber frame specialists develops more stylized, and buildable, designs. Details make or break a project, and expert timber frame insight from the concept phase keeps your design on track from the start.

  • Minimize redesigns and costly changes by aligning the frame with your intent early
  • Incorporate stylized details: joinery and exposed structure, designed in
  • Cohesive structure, aesthetics, and style in the finished building
  • Fewer oversights and RFIs, with no vague “builder to verify” notes
  • Delegate structural responsibility for the timber frame to our specialist team

For builders

We work with your architect to resolve every timber frame detail during the design phase, eliminating surprises in the field and delivering smoother construction with fewer headaches.

  • Every detail ironed out early, minimizing RFIs and change orders
  • Full timber frame services: engineering, shop drawings, prefabrication, sanding & staining, installation
  • Flexible delivery: full installation by our crew, or a contractor kit for yours
  • Complete installation support: hardware, fasteners, pegs, splines, wedges, shop drawings, and instructions

From the first drawings to seeing the frame standing in place, it has been a pleasure working with you. The craftsmanship, precision, and care that went into every timber are remarkable. It all fits exactly as it should, and the beauty and quality exceed our expectations. This timber frame will be the heart of our farmhouse for generations.

Dealia and Dan designed and built us a screened-in timber frame porch, a gated deck, and a long set of outdoor stairs, and we’re delighted with the results. They’re skilled, reliable, and a pleasure to work with. For the level of craftsmanship, materials, and design, the value for money was outstanding. We highly recommend Mufferaw Log and Timber Homes and look forward to working with them again.

I looked around for a designer that had the knowledge to guide us in the building process. We found that but also found a patient, friendly, customer oriented person who genuinely shared our passion for our build. I would highly recommend.

Where do you build?

We are located in the Ottawa area and are proud to serve all of Ontario. Because the more time-consuming work is done in the shop, our crew of experienced timber framers can travel to your site for an efficient installation.

What wood species are typically used?

Our most commonly used species are Eastern White Pine and Douglas Fir. If you have a specific species in mind, let us know. We are able to access a variety of species.

At what point in my build should I reach out?

A lot of timber framers prefer to work from architectural plans provided by the client, but we love being involved from the very beginning. It lets us work with your architect or designer to develop a well thought out frame, focusing on the details that make the difference, right from the start.

What is the typical scope of work?

Typical scope includes design, engineering, prefabrication, and installation of the timber frame or log building. Depending on the project, it can also include roof build up (not including roofing finish) and the building envelope (SIPs).

What are the advantages of SIPs on a timber frame?

SIPs (structural insulated panels) are an excellent way to close in a timber frame:

  • They are efficient to install
  • They create a tight building envelope with good R-value, so your building is efficient to heat and cool
  • They can achieve large, unsupported spans, which work extremely well with timber frame construction
What about engineering?

We work with engineers who specialize in heavy timber construction and traditional joinery. If your project requires an engineer, it is covered, without compromising any of the traditional details that make a timber frame a timber frame.
