deJong Studio Portfolio in Motion

This project centers on the expansion of an artful 1950s mid-century modern home designed by an architect for his own family. The client, who is also the architect’s grandson, seeks to enrich and expand upon the environment envisioned by his grandfather with thoughtful new ideas on living and growing for the future generations of this family.

Old Saw Mill Road, Clifton

Design Underway

Through substantial alteration and renovation, this wonderfully quirky 1970s modern home embodies all the character of a charming Vermont ski house. The design includes a re-envisioned kitchen/dining room and the creation of new spaces like a second master bedroom suite, a study/homeschool room, a reading niche, and a powder room.

Berkeley Street, Falls Church

Construction Complete

Perched over Rock Creek Park, this 1960s modern home has seen a complete revival with “Passive House” renovations. Grounded in sustainability with “smart wall” construction and geothermal HVAC, the home’s alterations include a cantilevered library addition, floating stair, stacked stone fireplace, and modern European kitchen design.

Covington Road, Silver Spring

Under Construction

This 1950s mid-century modern home, designed by architects Satterlee and Lethbridge, was once owned by the historic Holmes Run Acres neighborhood builder. Its new owners require a thoughtful expansion to accommodate a primary suite, study, and future garage. The design features a cantilevered all-glass bay that reaches out to the woods. 

Westminster Court, Falls Church

Currently Bidding

This project, for a repeat client, involves alterations to the original compact kitchen. The 1950’s mid-century modern home is a stunning example of the modified ‘Bodor” model designed by architects Satterlee and Lethbridge. The new kitchen design features enlarged front windows,  bespoke cabinets and functional elements inspired by the efficiency of a ship galley.
