Lot Selection

First, we help you find and select the best lot for your new dream home in the right neighborhood or area.


After a thorough consultation with you about your “wants” and “must haves”, our design team will create the perfect home for your personal needs.


Once you have approved the final design, our team of high-quality trade and craftsmen go to work to complete your elegantly designed home in a timely fashion.

Gallery of Homes

Keystone Development will build a high-quality custom home for you that is a reflection of your family’s personality and meets your specific needs. We will work one-on-one with you so every detail of your home is tailored to your family’s lifestyle, taste and budget. That personalized attention to detail is what sets us apart from the rest of the builders who build template homes.

Featured Projects

Our clients understand the importance of hiring an expert to guide them through every detail during the design process and partner with them all the way through construction.
