Bill and I have just spent the weekend here at Gum Road. Whenever we're here we say how much we love this house, and we know we have your Dad (and you and all the great crew) to thank. So, before we leave, I wanted to send our warmest New Year wishes to your Dad and to you. We hope it's a great year for all!

Pam and Bill Oetgen

We have had a relationship with Dieste Design Build for over twenty years. Having built two homes and a complete remodel of a third home for us, I can say without reservation that my husband and I have been more than pleased. From keeping a pristine job sight, to jobs completed in a more than timely fashion and open lines of communication, he had exceeded our high expectations.

Betty Ann and Corky Crovato

We were uncertain what to expect in delving into such a large undertaking in tearing down an existing property and designing and building a home from scratch. We could not have selected a better builder than Mark Dieste and his team. Their work was top notch and the responsiveness to changes/adjustments made project a wonderful experience.

It was an honor to have our home included on the Bethany Cottage Tour and featured in Delaware Beach Life. We would recommend Mark Dieste Design Build without reservation.

Jim and Cindy Tippett

Our family had the pleasure of working with the Dieste Design/ Build team and their great subcontractors, to build a wonderful home in Bethany Beach or Ocean View, DE.

Mark has a great eye for the classic beach house with aged pine floors, spacious modern kitchens, and large porches with fun awnings, making each home uniquely Dieste.

We look forward to many great years there with all our family members.
