A Residential Design Firm in Maryland: Who We Are and What We Do

“Passionate people serving clients who know what passion is”—that would be the best way to describe what our residential design firm is all about. We approach every project with a unique perspective that few companies possess and we study every aspect to ensure that it will serve the client’s needs, both practically and aesthetically. Project development does not end when we feel we have a solution to a problem—it’s only complete when we have the BEST solution to the problem.

Our projects are normally complex and require extensive customization. As a full-service residential design firm in Maryland, we have the ability to provide our clients with everything they will need, whether it’s millwork from our own line of cabinetry, custom-sized windows and doors, or lighting designs, to accomplish their specific goals. We realize that our clients want their projects to be as unique as their signature, and we will stop at nothing to make that happen!

The Design Process

We strive to achieve a single vision with our designs. To accomplish this, we have to consider each detail and often gather a team of people to assist that can include:

  • The client
  • Interior decorators
  • Engineers
  • Landscapers
  • City and county officials
  • Anyone else who will be involved in the final outcome

Armed with this wealth of information upfront, we design projects that meet every client’s unique needs and ensure the best outcome. We start with form and function and work our way to the aesthetic, priding ourselves on creating the best-built custom homes that are award winning in design.

The Build Process

After we have completed the perfect design and obtained the proper permitting and approvals, we are ready to start your project. We will present you with a detailed schedule of all the critical stages a long with the progress payment schedule.

Our residential design firm has a full-time site manager who handles the efforts of our staff and trade partners. Additionally, we use only the finest materials and strive to exceed all the standards to produce a truly one-of-a-kind product that will last for generations.
