The Pope-Leighey House Visitor Center is compromised of 3 masses with a hierarchical central core as a symbol to unify the Woodlawn Plantation to Frank Lloyd’s Wright Pope-Leighey House. The natural materials frame and unify the circulation of the two historic sites. The building system offers a cross laminated timber construction with a layering of an exterior pre-cast concrete cladding system on the two volumes that flank the central core. Users approach the building from the parking and follow along building edge leads directly to the usonian house. Along the exposed wooden canopy, users can contemplate at the reflection pool or enter the center that houses ammenities, such as an event space and library. The exterior canopy is also reflected in the interior with the wide corridor serving as a linear gallery. Pope-Leighey House

MANUMIT FREEDOM DISTRICT MEMORIALIZING FREEDOM
SITE : RFK STADIUM, WASHINGTON, DC COURSE : ARCH700 - URBAN DESIGN STUDIO PROFESSOR : MATTHEW BELL SEMESTER : FALL 2020 TIMELINE : 6 WEEKS TEAM : DANIELA TONI
The Freedom District transforms the existing RFK Stadium site with an urban fabric that establishes a strong gateway to DC and an axial approach to the Captiol Building. The new development uses the existing phases of the sport fields and the future development of Reservation 13 and preserves the existing main traffic roads: C St NE, 19th St, and Independence Ave SE. The masterplan consists of 3 main features: a Freedom Park across from the DC Armory and proposed museum, a Freedom Pedestrian Mall that perserves the street character of East Capitol Street, a Freedom Plaza and Tower dedicated to slave abolitionists, and Freedom Galleries as underpasses connecting to the Anacostia Riverfront Trails.

ADDRESS : UNIVERSITY OF MARYLAND COURSE : ARCH601 - TOPICAL STUDIO PROFESSOR : PETER NOONAN SEMESTER : SPRING 2020 TIMELINE : 10 WEEKS
THE SCHEME OF THE ARCHITECTURE SCHOOL AT UNIVERSITY OF MARYLAND ENCOMPASSES 4 BARS THAT FORM AN OVERALL C-SHAPE WITH AN HIERARCHICAL EMPHASIS ON A CENTRAL LIVING ROOM. THE EXTERIOR BRICK PERIMETER IS FORMED BY ITS SITE CONDITIONS CREATES A STRONGER MALL EDGE, WHILE THE INTERIOR COURTYARD PERIMETER CONSISTS A FRAMING CONDITION AND CHANGES IN MATERIALITY. DUE TO THE MULTI-APPROACH TO THE SITE, A POROUS ELEMENT AT THE NORTH SIDE INTRODUCES A BREEZEWAY STAIRCASE TO THE COURTYARD. THE COURTYARD SERVES AS A GATHERING AND LEARNING SPACE BY CAPTURING AND TREATING RAINWATER INTO AN UNDERGROUND WATER CISTERN SYSTEM.

U-Shape
Height Context 22
Generated by its surrounding building heights, Mount Vernon Apartment consists of 3 volumes of various heights sitting on a squared base that form an overall U-shape. Located in the historic district, this project preserves the street building height line. The project conforms with the history of the street and present day by intertwining modern and neoclassical features. The apartment follows the classical language of a bottom (retail), middle (residential), and crown (penthouse) and repetitive rhythmic bays on the facades. With the objective of connecting habitable and public gathering spaces, the side alley was transformed into a promenade that leads users on a procession of stairs and a water feature toward an elevated green courtyard.

RECONFIGURE ANNA COOPER HOUSE
TRANSITIONAL RESIDENCE RENOVATION ADDRESS : 1338 R ST NW, WASHINGTON, DC 2009 FIRM : MINER FEINSTEIN ARCHITECTS ROLE : ARCHITECTURAL STAFF TIMELINE : SEPT. 2017 - PRESENT (1 YEAR) EXPECTED CONSTRUCTION : FALL 2020
Concept Collage 28
The Anna Cooper House currently serves as a transitional residence of 52 irregular-sized units between the residential district and business district on R Street. For this renovation project, I reconfigured single room occupied units and common spaces (shared bathrooms, shared kitchens, community room, and lounges) into regular sizes in order to create efficient spaces and maximize accessibility under UFAS. As the exterior footprint and envelope of the building remain, I simplified the facade by adding new trim and contemporary windows that mimic those of the business district. The new facade serves as the center of a temporary home for the homeless population who are transitioning to permanent housing. The design underwent multiple design evolutions as I collaborated with a team by producing the floor plans, elevations, renderings, and unit axons.

REJUVENATE 1521 17ST ST NW
HISTORIC MIX-USED ROWHOUSE REHABILITATION ADDRESS : 1521 17TH ST NW, WASHINGTON, DC 20036 FIRM : MINER FEINSTEIN ARCHITECTS ROLE : ARCHITECTURAL STAFF TIMELINE : MAY - OCT. 2017 (5 MONTHS) CONSTRUCTION COMPLETION : FALL 2018
The proposed renovation of 1521 17st St NW rejuvenates the abandoned 3-story mixed-use rowhouse (built in 1880) on the lively street in the Dupont Circle Historic District. New features include expanding the building back to the rear alley in order to maximize space, adding a setback fourth-floor mezzanine to preserve the historic street line, and incorporating new programs: a future restaurant with a new retail bay as a memento of the old historic bay, three 1-bedroom residential units, and a master suite unit consisting of a loft bedroom. In this rehab project, I assisted in developing the layouts of the units, designed the new rear facade, and created visuals for the meeting with the Historic Preservation Review Board.
