Principals

Carl Landow, Architect

A registered architect since 1973, Mr. Landow brings to the team a broad background in the programming, design and construction of residential remodeling projects. A professorship in the School of Architecture at the University of Virginia and an active practice in Charlotteseville has led to his extensive residential design/build experience in northern Virginia. His ability to guide client-design/build teams through a clear decision making process has resulted in many successfully completed projects based on economical solutions  exacting in their response to functional needs and aesthetically well resolved, consistent with their existing contexts.

James Cassell, President

Mr. Cassell has worked for and owned home improvement companies in the Washington DC area for the over 30 years.  After he graduated from college with a degree in biology, Mr. Cassell started as a carpenter with Case Design Remodeling. He was employed by Case for 13 years learning his trade as a master carpenter, project manager and vice-president of construction before starting Greenwald/Cassell Associates and Chevy Chase Design/Build.  Both were partnerships where he acted as CEO. Desiring a closer more attentive relationship with his clients and to maintain his high standard of quality work, Mr. Cassell founded Great Falls Design/Build with head architect Carl Landow in 1999. Mr. Cassell has lived in Great Falls for over 30 years and experienced the regional growth first hand. He has worked in some of the finer homes, embassies and businesses in the Washington area over his career. The Great Falls Design/Build approach is to maintain a small firm thus allowing him to have a “hands on” practice. He enjoys working directly with the construction team, clients and occasionally with his hands to help produce quality projects of which he can be proud.

Susan Cassell, Designer

Manager of our small jobs and handyman division, G F Handy.  Susan assists in bringing your dreams and wishes into a realistic layout or plan.  After a detailed interview process, your wants and needs are identified and incorporated into a design plan.  Then she helps that plan come into being by managing your project until it is finished.  Specializing in kitchens, baths, office spaces and exterior remodeling, Susan makes the design flow efficiently and purposely with the homeowner in mind.  With over 25 years of managerial and customer service experience, Susan most recently managed our sister company, Variety Windows & Exteriors.  After many requests by our clients for handyman services, Jim and Susan started a handyman division, G F Handy.  After realizing the duplication of services between Variety and our new handyman division, Jim and Susan combined them together under Great Falls Design/Build, Ltd.  Now we can provide our clients everything they need from the small repairs to replacing their doors, windows, and siding to a complete remodel of their home.  Susan is eager to meet with you today and help your dream home come true.
