A Collaborative Process That Clients Remember
For over three decades, SP Architects has been creating homes and buildings that feel as if they have always belonged. We believe architecture is as much about people as it is about structures. From our first conversation to the final walkthrough, our goal is for our clients to say, “That was engaging and fun.”
Because no two projects are alike, we listen closely and tailor our designs to each client’s needs, values, and vision. Every client’s voice matters, and every design challenge is met with thoughtful solutions that balance creativity with precision. This open process builds trust and confidence, turning complex projects into shared accomplishments.
Through it all, clients rely on us to hold the big picture while caring for the details. By uniting a commitment to craftsmanship with modern sustainability, we create spaces that are enduring, functional, and deeply personal. The result is architecture that inspires, connects, and enriches life for generations, and a process that clients remember as one of the most rewarding parts of their journey.
Guided by Founding Architect Sheldon Pennoyer, whose work has been recognized with numerous design awards, our team brings both experience and curiosity to every project. Sheldon’s decades of practice in residential, institutional, and community design are paired with the fresh perspectives of a talented, collaborative team. Together, we blend deep expertise with creative energy to deliver thoughtful, enduring architecture.
