Tradition at D’Alonzo & Associates has arisen out of common desire to further develop concepts in design that are user friendly, from the overall planning to the refined details of the project. The Associates and Staff of the firm have held positions in architectural offices of note, and carry that forward into delivering customized personal service to each client. Additionally, this broad scope of experience has allowed for the successful completion of a full range of building types.
Projects of note that have been successfully implemented include:
  • LeBus Bakery, King of Prussia, PA
  • Fiji Salon, Haverford, PA
  • Poggenpohl Showroom, Philadelphia, PA
  • The New Campus Master Plan for The Valley Forge Specialized Educational Services Corporation (The Vanguard School and Crossroads School in Paoli, Pa.)
  • The Wynnewood Shopping Center

  • Multi-family projects, Philadelphia, PA
  • Custom Homes, Main Line, Philadelphia, PA, & NJ
Other projects include numerous bank structures, custom residences, new and renovated of various sizes, primary and vacation uses.
All our designs carry forth our unique design services (included computer aided design), culminating in a design product that fits both the budget and design sensibilities of each client. The firm is perfectly sized to offer personal attention to your project, and our dedication to service and quality is a tradition we are proud to uphold.

We look forward to working with you.
