How the Living Region House Cost Calculator Evolved

TL;DR: If you are weighing an affordable home, this history shows how to read the difference between a supplier’s starting price and a modeled home-ready budget. Living Region’s calculator grew from a household affordability model into a source-backed estimate with visible construction layers, owner-labour value, financing scenarios, and selectable dwelling options.

All figures are Canadian dollars (CAD) from dated model snapshots.

A household affordability model grows a dwelling calculator

People comparing modest homes need to know what a listed package includes, what it takes to make a dwelling usable year-round, and how financing changes the monthly picture. Living Region’s housing work began with a household-first affordability experience. On August 15, 2026, the repository added a model for the recurring utility costs associated with the dwelling. That work described the cost of operating a home; the next step was to estimate the one-time cost of acquiring and completing the dwelling itself.

On September 5, the first standalone House Cost calculator brought those questions into one interface. Its initial 30-foot reference dwelling measured 65.67 square metres gross, with 63.04 square metres of usable floor area after layout deductions. Those dimensions feed quantities for flooring, the platform, insulation, and labour. The model reported $103,651.85 in upfront cash and $108,247.21 in completed dwelling estimate, including the estimated value of owner labour. The earlier central dwelling estimate was about $61,000. Comparing the two figures raised a practical question: which parts of the total came from a wider scope, and which came from the way costs were counted?

An audit separates bundled prices from added labour

I compared the new calculator with the earlier estimate and asked for an audit of the gap. The older $61,240 central figure came from a $50,000 combined design-brief allowance for the structure, platform, heater, and chimney, plus household utility packages. The first calculator used detailed rows for those same systems, then added some labour and fees separately.

The September 5 audit found several overlaps. The water and plumbing package was $5,940 and already included labour and a permit allowance; the new calculation had added $2,745 more for labour. The $2,000 hot-water package already included integration labour, while the new model added $630. The $3,300 electrical package included qualified labour and inspection, while the new model added $900. A further $600 permit allowance also appeared in both places. The audit removed $4,875 in direct cash overlap, then recalculated tax and contingency. It kept other differences in structure, fit-out, and planning allowances visible for further review.

The audited model, published September 6, recorded a $97,786.64 cash construction budget and $4,595.36 in owner-labour value, for a $102,382.00 economic cost. Here, “economic cost” means the cash estimate plus the value assigned to work the owner contributes. The revisions that followed changed the model’s inputs and included work, so each figure below belongs to its own dated model version. The sequence shows three different kinds of progress: removing duplicate allowances, replacing rough inputs with supplier evidence, and defining exactly which completion work the standard scenario includes.

Model snapshot	Cash estimate	Owner-labour value	Economic cost
First calculator, September 5	$103,651.85	$4,595.36	$108,247.21
Audited model, September 6	$97,786.64	$4,595.36	$102,382.00
Supplier-price rebuild, September 5–6	$103,645.70	$2,466.59	$106,112.29
Layered supplier model, September 6	$97,630.66	$2,177.54	$99,808.20

Supplier evidence turns one total into a build-up

The supplier-backed rebuild priced the estimate component by component, using published yurt packages—a yurt is a round, frame-supported dwelling—and adding a quantity-based platform estimate, household systems, labour, tax, and a contingency buffer. Its central example selected Yurts Canada’s installed 30-foot package at $36,404. That version produced a higher completed estimate than the audit because the model’s package, platform, assembly, and labour basis had changed. The move established a clearer evidence trail: readers could see which amounts came from supplier prices and which remained planning allowances.

The selected Yurts Canada price covered an installed, all-season package: the frame, insulation, weather coverings, interior liner, dome, and supplier installation. The price began the estimate; a floor and platform, delivery, heating, plumbing, electrical systems, and interior partitions appeared in later layers. The model also compared public installed prices with non-binding import estimates and supplier configurations that required a quote. Those evidence labels helped readers distinguish a published amount from a planning estimate or a pending price.

The September 7 model laid the 30-foot example out as five additive layers. Its first layer was then called “Yurt package”; October’s “Frame package” label came later. Each row shows the added cost and the amount accumulated after that layer.

September 7 layer	Added cost	Running total
Yurt package, installed 30-foot example	$36,404.00	$36,404.00
Platform and foundation	$8,218.49	$44,622.49
Year-round completion	$9,016.63	$53,639.12
Basic household amenities	$12,735.47	$66,374.59
Delivery, design, permits, tax, contingency	$21,707.28	$88,081.87

The platform layer used measured quantities for deck blocks, beams, joists, decking, and floor insulation. The completion layer included a stove and chimney, ventilation, a privacy partition, and floor protection. Household amenities covered water collection and treatment, sanitation, hot water, and off-grid electrical equipment. Delivery, design, permits, taxes, and contingency completed the cash budget. The platform itself was a preliminary deck-block concept, so its dimensions and material list were visible inputs for later site and engineering review.

The completion scope was selectable. The basic completed dwelling included heating, ventilation, a privacy partition, protective floor covering, and a simple counter. Decorative finish, kitchen cabinetry and appliances, and bathroom storage could be priced as additional choices. That change explains much of the move from the September 6 layered model to the September 7 total: the default described a specific minimum completion package, while other items remained individually available.

The calculator also exposed owner-builder, mixed-labour, and contractor-built scenarios. These settings let a household compare paid work with the value of hours it contributes. A cash construction budget tracks money paid into the project; the economic total adds the owner’s work as a cost with value. Keeping both figures visible gives households a better basis for comparing how a build could be carried out. The corresponding tests checked the five items in the basic-completion preset, reconciled the layer totals, and exercised the mortgage calculations. This tied the public breakdown to the same calculation rules used by the estimator.

The calculator then separated the dwelling estimate from its mortgage scenarios. A mortgage model added dated Canadian interest-rate evidence, down-payment choices, mortgage insurance, and a stress test—a higher rate used to show how payments could change. For example, its September snapshot used a 4.01% fixed-rate reference for an insured mortgage, observed on June 30, 2026. A construction budget estimates the cash needed to complete the dwelling; a mortgage scenario estimates payments for a selected loan over time. Land, site lease, shared infrastructure, and household operating costs remain separate parts of the broader affordability picture. The first calculator used a simple 6% rate over 25 years. The later model replaced that single assumption with dated market evidence and several down-payment cases. At the selected frame-package stage, its September example showed $178.49 per month at 4.01% with 10% down; a 6.01% stress test showed $217.85 per month. Those payments describe financing the package stage, and selecting more completion layers changes the loan amount.

More dwelling sizes and a clearer path through the estimate

The first calculator centered on one 30-foot reference dwelling. In early September, the ordinary residential selector gained a 20-foot minimum while keeping 30 feet as the default. Supplier evidence also added 24-foot and 27-foot options, an exact 32-foot import estimate, and larger 35- and 40-foot shells from Shelter Designs. The 35- and 40-foot entries used United States base prices with indicative Canadian-dollar conversions; shipping, customs, local installation, and engineering remained separate planning questions. The 12- and 16-foot packages stayed visible as seasonal, experimental, or special-engineering references. For a fair comparison, readers can match each option’s included items and evidence label before comparing its price: a public installed package, an import estimate, and a quote-required configuration describe different levels of readiness. As the selected diameter changed, the model recalculated floor area and quantity-driven components such as the platform. It also moved dwelling design and size ahead of the completion-stage choice, so the physical home shaped the estimate before users selected how much work to include.

The same development period improved how the information appeared on screen. A table-header overlap was corrected, the opening price callout was removed, and the introduction was rewritten to describe the tool as a planning estimate. Together, these changes helped the reader move from selecting a dwelling to reviewing its size, completion layers, and assumptions.

Git history: add larger imported yurt-shell evidence, set the default completion scenario, show dwelling design before completion stage, expose larger shell sizes, fix the house-detail table header, remove the opening-price callout, and clarify the calculator introduction.

Interior finishing and electricity become explicit choices

On September 16, the model added separate interior finishing choices. This gave readers a way to examine the dwelling shell, essential completion, and optional finish work as distinct parts of the estimate. On September 30, an optional grid-electricity servicing mode extended the household-systems comparison alongside the off-grid setup. Both changes expanded the choices people could compare while preserving the distinction between one-time dwelling costs and the ongoing cost of operating a home.

The frame-package label closes the recorded history

By October 20, the opening cost layer had been renamed from “Yurt package” to “Frame package.” The new label described the role of that first layer in the estimate: it is the structural starting point, followed by the platform, completion work, household systems, and project costs. Yurt supplier evidence continued to support the model’s examples.

A live-browser check then caught an older label in the introduction. A follow-up corrected the display order, and the dwelling-scope description was clarified. On October 23, the interface added the footprint beside the diameter controls. “Footprint” means the ground area occupied by the dwelling; displaying it alongside diameter helps readers connect the shape selector to the space a home uses.

Git history: rename the opening layer to frame package, correct the frame-package label, clarify dwelling scope, and show footprint beside diameter.

Through October 23, the calculator’s history moves from a recurring-cost model to an adjustable estimate with supplier evidence, defined completion layers, mortgage scenarios, and multiple dwelling choices. For a new reader, the key is to follow the selected structure through each added layer, then read cash construction, owner-labour value, and mortgage payments as related but separate figures. A practical comparison starts by checking what the supplier package includes, which completion choices are selected, how work is divided between paid and owner labour, and which taxes, permits, and contingency amounts the scenario carries. Land, site lease, shared infrastructure, and ongoing household expenses connect to the broader affordability model. That sequence makes the total easier to inspect and gives future, more focused articles a shared starting point.
