Think of what’s involved in the design of a modern rooftop deck to complement an existing steel-framed condominium high-rise in Silver Spring, MD. Or imagine the complexities of the historic renovation of a Beaux-Art style 70-unit residential complex in Logan Circle in Washington, DC. In instances like these, our architectural services ensure that the projects’ results meet developers’ expectations, client’s budgets, and end-user’s needs.

For instance, the condominium’s rooftop deck needed to be more than just an outdoor amenity space — it also had to comply with the American Disabilities Act and International Building Code. The proposed deck was elevated on a new steel structure that allows for access for any future roofing repairs. And for the historic window replacement, in our nation’s capital, our renovation work had to be carried out in close cooperation with a renowned historic preservation specialist.

Because today’s construction projects explore new materials, as well as the latest installation methods, you absolutely want to establish a professional communications bridge between building owners, designers, contractors, and tradesmen. That is why, at ETC, we offer superior architectural and engineering services so that there are no lapses in communication that could impact the final results of your project.

From façade and historic building renovations to additions and new building designs, we’re proud to make sure projects throughout Virginia, Maryland, and Washington, DC progress smoothly — from design to completion.
