Last Thursday was the 13|U grand opening celebration on the corner of 13th and U streets, at JBG Smith’s newest luxury residential development. The cocktail reception took place on the building’s rooftop terraces, which feature a resident lounge with fireplace, grilling stations, outdoor kitchen, fire pits and views of the U.S. Capitol and Washington Monument. Here, Style Your Selfie’s Keke Olisemeka, D.C. Fashion Fool’s Barnette Holston and Eater DC’s Tierney Plumb.

The new building features 129 apartments ranging from one-bedroom to two-bedrooms with den. The units feature hardwood flooring, nine-foot ceiling heights, stainless steel appliances such as built-in refrigerators, quartz countertops and bathrooms with floating vanities and double sinks. Here, District Delicious founders Kristen Dominguez and Uppi Raj.

The building’s interiors were designed by New York-based Champalimaud. Guests got to tour the building’s model unit and sampled desserts from a chocolate bar. The 13|U complex offers a fitness studio with personal trainer, private underground parking, a state-of-the-art key system and a full-service concierge. JBG Smith is also offering a full-year membership to VIDA Fitness’ Penthouse Pool Club for new residents leasing two-bedroom units. Here, JBG Smith’s Wynne Anderson, Streetsense’s Genevieve McManus and Lauren Zillinger curl up by the south terrace fire pits.

The project is eco-conscious and features Energy Star appliances, high-efficiency HVAC units, electrical vehicle charging stations and low-emitting materials for paints and coatings. Here, TTR Sotheby’s International Realty’s Jackson Verville, Starbuck’s Joe Renda and Toll Brothers’ John Piedrahita.
