What Is Included in a Custom Timber Frame Home Kit?

‍

The word kit sets the wrong expectation. It suggests a flat-pack house that arrives ready to assemble, when a custom timber frame kit is something narrower and more precise: a manufactured structural and enclosure package that carries your project from the foundation to a framed, insulated, weather-tight shell. Almost everything after that point, the interior walls, the cabinetry, the flooring, the mechanical systems, is the work of your general contractor and the trades they coordinate.

‍

This is the most common source of confusion for first-time buyers, and it is the difference between a smooth build and a budget surprise. Knowing what sits inside the package, what sits outside it, and how the scope can be layered is what lets you read a quote accurately.

‍

What Does a Custom Timber Frame Home Kit Include?

‍

A serious residential kit is a layered package, not a single product. At Canadian Timberframes the residential offering is the Enclosure Package, and it is a representative example of what a complete custom timber frame kit looks like. The package is organized in layers.

‍

• Heavy timber frame. The frame is Douglas Fir number one grade, air-dried and surfaced four sides, with members 8x8 and smaller cut free of heart centre. It arrives with precision CNC joinery, a protective stain and clear top coat, end-sealing for drying control, and oak pegs, timber fasteners, and adjustable post-base connectors where exterior timber meets concrete.
• Custom metal connectors. The connectors are designed and modelled in three dimensions to match the frame, and they carry a powder-coated finish.
• Roof system. The roof system comprises pre-finished tongue-and-groove Douglas Fir decking, a PolyIso built-up roof assembly with ice and water shield, insulation, and plywood, structural-screw strapping, and conventional framing for any non-timbered roof areas.
• Exterior walls. The exterior is an engineered open wall system with PolyIso insulation, studs, plates, window liners, doubled headers, plywood, and factory-installed strapping for siding.
• Floor systems. The floor systems use engineered I-joists, hangers, LVL and rim joists, tongue-and-groove plywood sheathing with construction adhesive, and pressure-treated sill plates with gaskets.
• Siding, trim, and fascia. The cladding is kiln-dried Select Tight Knot Western Red Cedar with a rough-sawn finish and two coats of factory-applied stain, and it ships with window trims, soffit trims, fascia, corner boards, and belly bands.
• Delivery to site. The package arrives labelled and sequenced for the raise.

‍

It takes a project from the foundation to a building that is framed, insulated, sided, and ready for the next phases: windows and doors, interior partitions, mechanical systems, and finishes.

What Is Not in a Custom Timber Frame Home Kit?

This is the part most buyers underestimate. The Enclosure Package takes the structure from foundation to weather-tight, and it stops there. It does not include the foundation itself, and it does not include the interior fit-out. A kit leaves the following scopes to others:

‍

• Cabinetry sits outside the kit, including kitchen, bathroom, and built-in cabinetry.
• Flooring is a separate scope, including hardwood, tile, stone, and carpet.
• Appliances are supplied separately.
• Interior partition walls, meaning the framing for non-exterior interior walls, are not part of the package.
• Drywall, paint, and interior finishing materials are handled on site by your trades.
• Mechanical systems, meaning HVAC, plumbing, and electrical, fall to your general contractor.
• Foundation and site work are completed before the package arrives.
• Lifting equipment is provided by your builder, who supplies the crane for the timber raise.
• Stairs and interior railings are often available as add-ons through the manufacturer, but they are not typically part of the standard package.

‍

Windows and doors deserve their own note. The wall system arrives with framed rough openings ready to receive the units, but the units themselves, the premium windows and doors and their hardware, are usually a separate scope. Your kit provider may supply and coordinate them as a package upgrade, or they may stay with your builder. Confirm this on every quote.

‍

The key takeaway: A timber frame kit delivers everything your manufacturer is best positioned to design, fabricate, and ship. It does not deliver the work done on your site by trades your general contractor coordinates. Both are essential to a finished home. They are simply different scopes of work.

‍

The Layered Scopes: From Frame Only to Full Enclosure

‍

A kit is not one fixed scope. It is a set of layers you can buy in combination, and most of the confusion between quotes comes from comparing different layers as if they were the same product. Reading from the inside out, the layers build up like this.

‍

• Timber frame only. This scope covers the structural posts, beams, rafters, connectors, and joinery, pre-cut and pre-finished. It is the smallest scope, and it assumes your builder supplies and installs the wall and roof enclosure around the frame.
• Timber frame plus enclosure. This scope adds the engineered wall and roof assemblies that make the building weather-tight. It is the Enclosure Package described above and the most common scope for a complete custom home.
• Timber frame plus enclosure plus glazing. This scope extends the enclosure with the windows and exterior doors supplied and coordinated as part of the package rather than left to the builder.
• Frame plus interior timber finishes. Any layer above can be extended to include exposed interior timber such as ceiling decking, feature beams, and timber stairs, where those are part of the design.

‍

‍

Each added layer moves more of the work into the controlled environment of the shop and out of the field, and each one changes the number on the quote.

‍

How Do You Read a Custom Timber Frame Kit Quote?

Once you know that a kit is layered, comparing quotes becomes a question of scope rather than price. Three rules do most of the work.

• Compare scopes, not totals. Two quotes at the same number can deliver very different products, and two quotes at different numbers can be the same product packaged differently. Itemize the inclusions layer by layer: frame, custom metal, roof, walls, floors, siding, glazing, and interior timber.
• Ask about exclusions explicitly. The most useful question you can ask is what is not in this quote. Anything excluded becomes someone else's scope, usually your general contractor's, and occasionally yours directly.
• Read the species and finish specifications. Douglas Fir, Western Red Cedar, kiln-dried, free of heart centre, surface texture, and factory stain are not interchangeable details. Material specifications are a meaningful share of the package cost, so a quote that omits them is not a complete quote.

Choosing between the providers who issue those quotes is a separate decision, with its own set of questions about design capability, material supply, manufacturing technology, and track record. We cover it in full in our guide on how to choose a timber frame company.

Frequently Asked Questions

How much does a custom timber frame home kit cost?

Kit pricing depends on size, complexity, finish specifications, and which scope layers you include, so the kit itself is only a portion of the total build. Rather than quote a range here, we break the numbers down in our companion guide on timber frame home cost, which covers package pricing and total build cost per square foot.

‍

Does a timber frame kit include the foundation?

No. Foundation and site work sit outside the kit. The foundation is designed and built by your general contractor before the package arrives, and the kit is engineered to land on the foundation you have built.

‍

Can I install a timber frame kit myself?

A timber frame raise needs a crane and a crew experienced with structural timber assembly. A skilled owner-builder with the right crew and equipment can take it on, but it is not a typical homeowner project. Most kits are installed by a general contractor with timber frame experience, working in coordination with the manufacturer.

‍

What is the difference between a timber frame kit and a log home kit?

A timber frame kit is built around structural posts and beams with infill wall and roof systems. A log home kit uses solid logs as both structure and exterior wall. They look different, perform differently, and use different construction methods. Timber frame suits modern custom homes and high-performance enclosures. Log construction is its own tradition.

‍

How long does a timber frame kit take to manufacture?

Lead time depends on package size, complexity, and material specifications, and premium options such as kiln-dried timber, free of heart centre members above 8x8, and custom finishes extend it. Engineering and design happen before the manufacturing window starts, so it is best to confirm a timeline against your specific project early in the design conversation.

‍

What is included in a Canadian Timberframes residential kit specifically?

The residential Enclosure Package includes the heavy timber frame, custom metal connectors, a complete insulated roof system, engineered exterior walls with insulation, timber stair components floor systems, cedar siding and trim, factory-applied finishes, and delivery. It does not include the foundation, site work, interior partitions, cabinetry, flooring, appliances, mechanical systems, or interior finishing materials.
