A few suggestions from experience:

1. Don't judge the builder by its sales presentation. Salespeople don't build the house; they only sell it for commissions. Homes are built by hundreds of trade subcontractors, which are only overseen by builder's superintendents. Builder's quality control and warranty service are the most important factors in your post-construction enjoyment of your home. Check the homebuilder's reputation online, word of mouth, talk to people on the street who built with them.
2. Nobody ever complains about having too large garage, too much storage, or too many kitchen cabinets. Plan ahead. Allow for more space.
3. People rarely need large bedroom spaces, contrary to what they might think.
4. Invest in the quality of curb appeal design (1), kitchen size & quality (2), usable area (3), in that order. These investments pay off best when it's time to sell.
5. Whatever is not included in your sales agreement AFTER it goes firm will cost you quite a bit more on a change order. There will be no more negotiations. Take your time, get what you want included in the agreement at the price you negotiate and accept. Reject the urgency from a salesperson. There is rarely a real urgency. They will wait for you. And the salespeople will be rooting for you with their sales manager to get what you want in approved.
6. Check Customer Choice Award record with BILD Calgary. It is awarded only based on customers' feedback. Morrison, Homes by Avi have been winning a lot of them lately, I think.
7. Mahogany is a great new community. Especially in summer. In winter - they are all bad, really, unless you live in Beltline or Sunnyside/Hillhurst. This is all very subjective, of course.

Good luck!
