Keystone Construction and Development, Inc. has been in the Magic Valley since 2006. During that time, we have built countless homes and developed several residential subdivisions.  We pride ourselves in having a trustworthy team where honesty, communication, attention to detail, and daily supervision is the foundation of our business. 

To learn more about who we are, please see our about us page.

Feel free to browse some of our ‘stock’ plans or contact us for help designing a custom home. If you already have your home design complete, bring it to us! We routinely bid existing home plans, and offer an ‘open-book’ business model so you can be involved not only with design and feature selection, but also financial decisions along the way.

Please contact us for a free consultation regarding your construction project. We also have a full service Real Estate Brokerage: Idaho Legacy Real Estate, Inc. that can sell your existing home, or help with any other real estate transactions!
