How Framing Cost Is Calculated for a Custom Home in the GTA

By Luiz Telles, Telles Contractors · Updated November 15, 2026

Short answer: the cost of framing a custom home is derived from its structural drawings. Every wall, floor, roof plane and steel member is measured and priced. Two homes with the same floor area can differ in framing cost by up to five times, because cost follows the engineering requirements of the structure.

Cost follows the engineering

Floor area tells you how big a home is. The structural drawings tell you how much work it takes to build. Consider two homes of identical area:

Home A Home B
Floor area Same Same
Plan Rectangular, stacked floors Open plan with long clear spans
Structure Dimensional lumber and standard joists Steel beams, columns and moment frames with engineered lumber
Walls Standard heights Tall walls and large window openings
Roof Simple gable or hip Multiple hips, valleys, dormers and vaulted ceilings
Connections Standard nailing and hangers Engineered hold-downs, straps and specified hardware
Framing labour Baseline Up to five times the baseline

Both homes have the same area. Home B carries far more structure inside it, and the quote reflects that structure.

How the final cost is derived

  1. Drawing review. We study the architectural and structural sets together: spans, load paths, steel, roof geometry and details.
  2. Takeoff. Our team measures and counts every component: linear feet of wall by height, floor system by type, roof planes, beams, posts, steel members, sheathing and hardware.
  3. Labour pricing per item. Each component is priced for the labour it takes to build. A tall wall, a steel moment frame and a vaulted ceiling each carry their own rate.
  4. Site and schedule. Access, staging space, crane and lifting needs and the season are added.
  5. Quote. The items total to a labour quote for framing and steel installation. Materials are quoted separately.

The engineering factors that move the number

Spans and structural steel

Open plans call for long spans carried by steel beams, columns and moment frames. Steel is received, lifted, set and connected to the engineer’s details.

Engineered wood

LVL, glulam, PSL and engineered joists each install at their own pace and often need specified fasteners and bearing details.

Wall heights and openings

Tall walls, large window walls and stacked openings use heavier members, more blocking and more hardware.

Roof geometry

Every hip, valley, dormer and change of pitch adds layout and cutting. Vaults, turrets and curved features are built piece by piece on site.

Lateral design and connections

Shear walls, hold-downs, straps and specified nailing patterns are part of the engineer’s lateral design and are installed and inspected item by item.

Site conditions

Infill lots in Toronto, staging space and crane access shape how material reaches the crew.

What to send for an accurate quote

  1. Architectural drawings: plans, elevations and sections
  2. Structural engineering set, including steel details
  3. Truss and engineered floor layouts, if available
  4. Site address and access notes
  5. Target framing start date

Frequently asked questions

How is the cost of framing a house calculated?

The cost is built from a takeoff of the architectural and structural drawings. Every wall, floor system, roof plane, beam, column and connection is measured and counted, and labour is priced for each item. The total of those items is the framing quote.

Can framing cost be estimated from square footage?

Floor area describes the size of a home, while framing cost follows its engineering. Two homes with the same floor area can differ in framing cost by up to five times once spans, steel, wall heights and roof geometry are accounted for. An accurate number comes from the drawings.

What makes one home cost more to frame than another of the same size?

Engineering requirements: long clear spans, structural steel, moment frames, tall walls, engineered floor systems, complex roofs, vaulted or curved features, and the hardware and connections the engineer specifies.

Does the framing quote include lumber and steel?

Telles Contractors quotes framing and steel installation as labour. Lumber, engineered wood and steel are quoted separately so each cost is visible.

What do I need to get a framing quote?

A complete architectural set and the structural engineering set, including steel details, plus the site address and target start date. Email them to info@tellescontractors.com.
