Remember to make sure your content includes keywords that match the terms people are likely to use when searching for a condominium or development in that geographic area. It is important to do so in the natural flow of the post though, rather than cram in search terms that might get the website flagged by Google for “keyword stuffing.”
You could also post a gallery for each project on its page, although I recommend you have enough text first to get you down below the logo, or else the layout might get confusing.
Each post will automatically appear on the Past Projects page, as long as you make sure the post is in the Past Projects category. Let me know if you need anything else!
