Cornerstone is one of NE Calgary's larger newer communities, and construction is still actively underway across various phases. That means buyers will encounter two distinct purchasing scenarios: quick-possession homes (also called spec homes), which are already built or near completion and can close within weeks, and pre-sale or pre-construction homes, where you select a lot and floor plan and wait several months for the build to finish. Quick-possession homes are practical if you need to move on a set timeline, while pre-sales allow more choice in finishes and features, but carry uncertainty around completion dates. Both types are well represented in Cornerstone's current MLS® inventory.
Understanding what a builder's advertised base price actually includes is critical before you write an offer. In most new Calgary communities, the base price typically does not include rear yard landscaping, fencing, window coverings, finished basements, or sometimes even appliances — these are either upgrades or owner responsibilities after possession. At the lower end of Cornerstone's price range (from the mid-$300,000s), you're generally looking at townhomes or apartments with a more defined finish package. Detached homes start higher and offer more flexibility for upgrades, with some reaching close to $939,000 for larger or heavily upgraded builds. Always request a full builder schedule of inclusions and a site plan showing what lot grading and landscaping is covered before finalizing your purchase.
Two financial considerations are unique to new construction in Alberta. First, GST applies to newly built homes — resale homes are exempt, but new builds are subject to 5% GST, partially offset by a federal rebate for homes under certain price thresholds. Your lawyer will walk through this at closing, but factor it into your budget early. Second, all new homes built in Alberta are covered under the Alberta New Home Warranty Program, which provides mandatory coverage for defects in labour and materials, building envelope issues, and major structural defects over different time periods. This warranty is a meaningful advantage over buying resale, where issues are typically sold as-is. Working with a REALTOR® experienced in new construction will help you review builder contracts, negotiate upgrades, and ensure your deposit is properly protected.
Frequently asked
What is the difference between a quick-possession home and a pre-sale home in Cornerstone?
A quick-possession (or spec) home is one the builder has already constructed or is close to finishing — you can typically take possession within a few weeks to a couple of months. A pre-sale means you choose a lot and floor plan and the builder starts construction after you sign; this can take six months to over a year. Quick-possession homes offer less choice in finishes but more certainty on timing, which is helpful if you're selling a current home or ending a lease.
Does GST apply when buying a new home in Cornerstone?
Yes. In Canada, newly built homes are subject to 5% GST, unlike resale homes which are GST-exempt. A partial federal GST rebate is available for homes below a certain purchase price threshold. In most cases, builders factor the rebate into their pricing and assign it to themselves at closing, meaning you pay the net amount — but you should confirm this in the purchase contract and speak with your lawyer or accountant so you know exactly what you're paying.
What does a builder's base price typically not include?
Builder base prices in communities like Cornerstone frequently exclude rear landscaping, fencing, window coverings, appliances (sometimes), and basement development. Upgrades to flooring, cabinetry, countertops, and fixtures are also additional. These costs can add tens of thousands of dollars to your total budget. Always ask for a detailed list of standard inclusions and request a scope of work that clarifies what will be completed on your lot before possession.
What warranty protection comes with a new home in Alberta?
Alberta mandates coverage under the Alberta New Home Warranty Program for all newly built homes. This includes one year of coverage for defects in labour and materials, two years for building envelope issues (like windows, roofing, and exterior cladding), and ten years for major structural defects. This is a significant benefit compared to resale homes, which are generally sold without warranties. Keep all documentation your builder provides at possession, as you'll need it to make warranty claims.
How is buying a new build in Cornerstone different from buying a resale home?
The purchase process for new construction differs from resale in several key ways. Builder contracts are typically the builder's own legal documents rather than the standard AREA forms used in resale transactions, and they tend to favour the builder — having a REALTOR® review them carefully matters. Deposits are usually larger and held over a longer period. Possession dates can shift due to construction delays. There's also no home inspection in the traditional sense during construction, though you do get a builder walkthrough before possession. On the upside, everything is new, under warranty, and built to current building code standards.
