  • “We hired Studio HA/WA to design our home in the city and then again when we bought a (second) home in the country. Erin is an incredibly talented designer and we were so grateful to have her leading both projects. She took the time to get to know our style and our family’s needs but after that took charge of planning every detail of our homes so the projects were completed seamlessly. Erin is organized, detail-oriented and worked tirelessly on our projects based on differing budgets and uses for each home. We truly love our homes and we owe that all to Studio HA/WA.”

    — CLIENT, BEACHES RESIDENCE

  • “Erin at STUDIO HA/WA was a dream to work with. She listened attentively to our hopes for our outdoor project and brought it to life. Her attention to detail, professionalism, exemplary knowledge and unique view took our project to the next level of design and created an outdoor living and dining area, outdoor kitchen and pool space. Erin coordinated a team of industry leaders and professionals to bring us to our final product.”

    — CLIENT, CRESCENT EXTERIOR

  • “This was the second home we hired STUDIO HA/WA to design for our family. We were so happy with the work the team at STUDIO HA/WA had done for us on our home in the city, we knew we wanted to have them involved in the interior design of our country retreat. Erin was involved in the process from the time we purchased the home all the way to furniture installation and ensuring the home was move-in ready. The team was able to work with our budget and timeline during the pandemic, which was no easy feat. They worked together with contractors and trades to manage the entire process and project on our behalf. They listened to our goals for the home, and surpassed them. The design of our country home is tranquil, contemporary and perfectly suited for its setting. We can't imagine taking on a project without STUDIO HA/WA's expertise and skill. The team at STUDIO HA/WA is hardworking, professional and creative, and we cannot recommend them enough!”

    — CLIENT, MARY STREET RESIDENCE

  • “When we first met with Studio HA/WA we were overwhelmed by the idea of doing a full home renovation and addition, and were unsure of how we would achieve our goals in the space that we have. After our first meeting we left feeling excited and confident - they helped us to see a vision for our space. They asked probing questions to ensure they understood our wants, likes and dislikes and presented a variety of creative design options and solutions that we had never considered for our home. We have really enjoyed working with the team at STUDIO HA/WA, they are extremely detail-oriented and professional and we look forward to working with them further on the next stages of our project.

    We would highly recommend STUDIO HA/WA if you’re looking for an interior design firm that can provide a unique and customized approach to your project.”

    — CLIENT, CANTELON RESIDENCE

  • “I met Erin few years ago through a common client and it was an instant connection, we were on the same page. Erin produced detailed drawings that were easy to follow. Any site conditions that were not in line with drawings were discussed and solution provided. We would call her contractor friendly designer! Erin doesn’t just copy the work that you see online, but creates custom design that suits each clients needs. That’s why clients also adore her and she cannot do wrong by them. Looking forward to the next project.”
