HD Squared Architects

Residential interiors including living room kitchen and bathroom renovations


“Melanie is one of those rare individuals who is able to think like an engineer and an artist at the same time. It seemed as if she immediately recognized what we needed to do with our space. This required creative interior design ideas to accommodate existing conditions. We could never have reached such a successful result without her input.”

– S.S., Multi-project Client

“HD Squared is driven not by their vision, but by the vision of their clients. With an uncanny ability to translate the vague dreams and ideals of her clients, Melanie Hartwig-Davis creates a solid and accurate translation that regularly exceeds function and style no matter the budge or site constraints. On top of this, she seamlessly integrates low-impact and healthy strategies in all of her work with a sensitive eye toward the environment and the comfort of her clients. She reminds us that being a good listener is not enough – that the actions we take from what we learn is the true measure of success.”

-R.P., Colleague

“Melanie Hartwig-Davis is truly a talented Architect with a uniquely creative sense of space and style. She is easy to work with and indeed cares about what her clients are trying to achieve while working within their ever present budgets. She is great at guiding her clients through the various steps of the design process and into construction and follow up upon completion. Probably equally important, her personality and professionalism makes her client’s projects fun and an enjoyable journey to a great finished project. I highly recommend HD Squared Architects.”

“I had a fabulous experience with HD Squared. I had an addition built with accompanying walkways installed. This was my first experience doing a major renovation and HD Squared walked us through each step with support and professionalism. I have since recommended friends to HD Squared and they also had a great experience. My addition is beautiful! I give HD Squared 5 stars, it’s a great company.”

“We hired HD Square for an updating of our cape style house in the DC metro area. The concept was to open up the very divided up space, create a new kitchen and have access to a new outdoor deck. The result was fantastic! The layout made life easy and the added open flow out to the new deck made the whole first floor ideal for entertaining. Important to note, the original charm of the home was not lost in the process. We highly recommend HD Squared for their insight, design ingenuity, and customer focus!”

“Melanie designed a complete kitchen redo in my 70+ year old house and her design included state-of-the-art upgrades while maintaining the integrity of the house’s charm and character. She was vigilant about staying within my budget. She also effectively managed the contractor and his subs. All in all, it was a fabulous experience.”

– B.S., Cheverly Ave Renovation

“Dear Melanie, We love our house!  Thank you so much for helping us out with the project.  I don’t know what we would have done without your creative ideas and architectural expertise…..Thanks again for everything.  You are very talented!”

– D.Y., Renovation Consultation

“We hired Ms. Hartwig-Davis to design a 3-story addition for our house in Cheverly in 2002. She explained to us at that time that she was a ‘green’ architect, which was a new phrase to use then. Despite the fact that some of her design plans would cost us more money due to her preference for working with environmentally friendly materials, she would not waiver in using other more conventional materials. She informed us of this stipulation at the beginning of our talks. We decided to proceed with Ms. Hartwig-Davis, although we could have saved money by using cheaper materials, and we are now very glad we did so. Her resolution almost 10 years ago to as she thought was right even if it meant losing a job is a quality that we admired then and still do now. We also now have a beautifully designed addition, which the town’s mayor thanked us in writing for building!”

– R.C., Forrest Road Addition

“Melanie really took the time to listen to my wants and needs, which changed a few times during the design process. In the end, my home turned out to be the perfect reflection of everything I conveyed. Happy client.”

– J.J., Crownsville Waterfront Home

“Melanie was able to translate my entire wish list and all my ideas into a wonderful design. She has an incredible attention to detail especially related to increasing the energy efficiency of the home. We love the final result.”

“Melanie and HD Squared did a fabulous job of designing the new kitchen-office-bath-laundry to give me the space and light I wanted while preserving and updating the character of my wooden cottage.”

-K.T., Renovation Consultation

“Melanie Hartwig-Davis of HD Squared designed my dream retirement home. I owned a modest 40 year old house on a waterfront lot. The lot had wonderful waterviews that were only visible from the windows over the kitchen sink and the bathroom. Melanie’s designs transformed my run down house into a upscale modern home that takes full advantage of the views and will accommodate aging in place. We gutted the interior and basically rebuilt the house. Her interior design ideas resulted in a terrific kitchen and a stunning master bath. I love the finished house.”

-M.M., Renovation Consultation

“I just started working with Melanie. I, as a builder, found her plans easy to work with. Her ideas were very creative and practical with a keen eye on both the budget and the environment. I look forward to our future endeavors. I have recommended her to my clients and will continue to do so. ”
