Acreage Servicing Estimator
On an unserviced parcel the well, the private sewage system, the utility extensions, the approach and the driveway are a separate project from the house — routinely a six-figure sum. This tool estimates each from parcel-specific inputs you supply, so you can compare two parcels on total cost rather than on asking price.
Open research Building termAgricultural Land Reserve
A British Columbia land designation protecting agricultural capability. On ALR land, residential use is subordinate to farming: house size can be constrained, additional dwellings require Agricultural Land Commission approval, and subdivision is generally refused.
Open research Building termAir barrier
The continuous layer in a wall, roof or floor assembly that stops air moving through it. Continuity matters more than material — every penetration is a leak unless deliberately sealed.
Open research Building termAir changes per hour at 50 Pa
A measure of building airtightness: how many times the interior volume of air leaks out per hour when the house is pressurised or depressurised to 50 pascals. Measured by blower-door test.
Open research Building termAllowance
A placeholder sum written into a building contract for an item that has not been selected yet — tile, plumbing fixtures, lighting, millwork. When the actual item is chosen, the difference is added to or credited against the contract price.
Open research Planning toolAllowance Tracker
An allowance is a placeholder in the contract for an item not yet chosen. Enter your contract allowance and your actual selection cost per category and this tracks the running over or under, applies the builder’s markup where it applies to overruns, and shows the total impact on your contract price.
Open research Building termApproach permit
Authorisation from the road authority for a new or altered driveway access onto a public road, typically covering the culvert and the apron where the driveway meets the road.
Open research Building termArchitect-led
A delivery model in which an independent architect retained by the client holds the design, and the builder is engaged to price and execute it.
Open research Building termArchitectural controls
Requirements registered on title or imposed by a developer governing design in a subdivision — minimum floor area, roof form, exterior materials, garage orientation, landscaping and completion deadlines.
Open research Building termBC Energy Step Code
A British Columbia compliance path setting escalating energy performance requirements verified by energy modelling and airtightness testing, rather than by prescriptive assembly tables.
Open research Building termBedrock
Solid rock beneath surface soil. Where shallow, excavation requires rock removal — hammering or blasting — which is a substantial and highly variable cost.
Open research Building termBlower-door test
A test that pressurises or depressurises a house with a calibrated fan to measure how much air leaks through the envelope, producing an airtightness result.
Open research Planning toolBuild Timeline Planner
Enter a start date and project characteristics and this returns dated phases through to possession, the date each long-lead item must be ordered by, and whether your foundation lands before freeze-up. Canadian custom homes commonly run eighteen months to two-and-a-half years, and the front half is where buyers underestimate most.
Open research Planning toolBuilder Quote Normalizer
Builder quotes are rarely comparable as written, because each one includes a different scope. This tool takes two or three quotes, records what each one includes and excludes, adds your own figure for every excluded item, and returns a normalized total and a true cost per square foot for each — so you are comparing the same house.
Open research Editorial guideBuilder Versus Architect: Who Should You Contact First?
Contact a builder first if budget certainty is your main concern and your design is conventional; contact an architect first if the site is difficult, the brief is unusual, or design is the point of the project. A common third path is retaining an architect and engaging a builder early for preconstruction pricing.
Open research Editorial guideBuilding Envelope and Performance: What to Specify and How to Verify
"Energy efficient" means nothing on its own. The things that can actually be specified and verified are an airtightness target measured by blower-door test, a continuous-insulation strategy, a commissioned ventilation system, and a certification path if you want third-party confirmation. Ask for numbers and test results, not adjectives.
Open research Build locationBuilding in Bearspaw
Bearspaw is an acreage area in Rocky View County immediately northwest of Calgary, typically two- to four-acre parcels on private wells and private sewage systems. Building here means a county development permit rather than a City of Calgary one, and it means the water supply is your responsibility to establish before you design.
Open research Build locationBuilding in British Properties
The British Properties is a hillside estate community above West Vancouver with substantial view lots and, on most of them, rock. Geotechnical assessment, blasting, retaining and equipment access frequently account for a very large share of the project cost — on a genuinely steep lot the site work can approach the cost of the house.
Open research Build locationBuilding in Calgary inner-city infill
Inner-city Calgary infill means buying an existing house in an established community, demolishing it and rebuilding. The Land Use Bylaw governs what fits on the lot, a Development Permit with an appeal period usually precedes construction, and the neighbours are twelve feet away for the duration.
Open research Build locationBuilding in Elbow Valley
Elbow Valley is a controlled estate community in Rocky View County immediately west of Calgary, with communal servicing, registered architectural controls, an active architectural review process and a residents’ association. It is the closest thing in the Calgary area to a fully serviced estate lot outside city limits.
Open research Build locationBuilding in Foothills County
Foothills County lies south and southwest of Calgary and includes De Winton, Priddis, Millarville and the country around Okotoks and High River. Parcels are generally larger and more rural than Rocky View’s, with correspondingly longer servicing runs and a distinct county approval process.
Open research Build locationBuilding in Glenora
Glenora is Edmonton’s established premium rebuild community, immediately west of downtown above the North Saskatchewan River valley. Two constraints govern building here: the mature-area overlay, which controls massing and character on infill, and — on lots toward the valley — slope stability review, which is a geotechnical question before it is a design one.
Open research Build locationBuilding in Lawrence Park
Lawrence Park is one of Toronto’s core custom rebuild communities — large treed lots, an almost entirely demolition-and-rebuild market, and two constraints that decide most projects: the tree protection by-law and the Committee of Adjustment.
Open research Build locationBuilding in Naramata Bench
The Naramata Bench is vineyard and orchard land above Okanagan Lake, and most of it sits inside the Agricultural Land Reserve. On ALR land the residence is subordinate to agricultural use: house size can be constrained, a second dwelling requires Agricultural Land Commission approval, and subdivision is generally refused.
Open research Build locationBuilding in Parkland County
Parkland County is Edmonton’s main acreage supply, west of the city toward Spruce Grove and Stony Plain. Private wells and private sewage, county development approvals on their own schedule, and utility extensions priced by distance — the same servicing picture as Rocky View outside Calgary.
Open research Build locationBuilding in Rockcliffe Park
Rockcliffe Park is a heritage conservation district, and that is the governing fact about building there. Design is assessed against published district guidelines before the ordinary planning process applies, demolition of a contributing building may be refused outright, and the landscape character — mature trees, deep setbacks, absence of curbs — is part of what is protected.
Open research Build locationBuilding in Rocky View County
Rocky View County surrounds Calgary on the north, west and east and contains most of the region’s acreage supply, including Bearspaw, Springbank, Elbow Valley, Bragg Creek and Langdon. County approvals, private servicing and land use designation are the governing considerations.
Open research Build locationBuilding in Springbank
Springbank is an area of Rocky View County directly west of Calgary along Highway 8 and Springbank Road, mixing controlled estate subdivisions with larger unserviced acreage parcels. Which of those two you are buying changes the project entirely: one carries architectural controls and communal servicing, the other carries a well, a septic field and full design freedom.
Open research Build locationBuilding in The Uplands
The Uplands is a planned garden suburb in Oak Bay laid out in the early twentieth century, and it carries design expectations to match. Registered controls and the District’s review shape what can be built, mature landscape character is protected in practice as well as by by-law, and rock is common on Vancouver Island lots.
Open research Build locationBuilding in Tuxedo
Tuxedo is Winnipeg’s established premium community, with large lots and consistent rebuild activity. The governing technical condition is not the neighbourhood but the ground: Red River Valley clay is highly expansive, and piled foundations with void form are standard local practice rather than an upgrade.
