HORWITZ ARCHITECTURE + DESIGN REVIEWS

We met Dulcie through an introduction from the property owner for this project. From our first meeting we knew we were working with not only a superb design professional but someone that exhibits great professionalism amongst all the parties involved in any project, mainly the client, the contractor and the other consultants. We recommend her to anyone needing an architect! We look forward to working with her and her firm in the future.

We had an idea for our remodel, but Horwitz A+D had a better one…a WAY better one! Their execution, management and follow-through made the whole building process remarkably easy.

I am currently working on my third project with Dulcie…. I am a hands-on homeowner who stays deeply involved in the entire process, and Dulcie is the ideal partner for me.

ARC DESIGN GROUP INC. REVIEWS

Excellent experience with Arc Design Group! Professional, creative, and easy to work with. They truly listened to our vision and delivered beautiful, functional designs on time. Highly recommend.

MNICHOLS DESIGN REVIEWS

Mark is amazing!!!!!! We hired him to re-do our house and could not be happier. He made incredible use of every inch of our square footage, turning awkward spaces into functional, beautiful rooms. The design is simple, chic, and timeless. He was professional, thoughtful, and attentive to our needs throughout the process. We highly recommend him to anyone looking for smart, stylish residential design. He used every square inch of our space.

Working with MNichols Design has been a pleasure. They are responsive, collaborative, and produce outstanding, efficient designs. As a Structural Engineering firm, we are happy to collaborate with them on any project.

Mark helped design our dream back house! There were so many moving pieces but we never felt stressed out as mark was able to be in loop at all times and communicated really well with contractors, our interior designer and the engineer. We knew from his renderings that he was talented and that we were making a special place, but it far exceeded all of our expectations. Thank you for the incredible work Mark.
