Collective Housing Community in the In-Between

Year: 2024 Fall Advanced I Studio

Instructor: Sabir Khan

Project Site: South Downtown Atlanta, Georgia

Site Dimensions: 160 ft x 175 ft

This project aims to transform an underutilized surface parking lot in Downtown Atlanta into collective housing that encourages and actively fosters community through various in-between spaces. The site serves as a connector between two streets with distinct characteristics - Broad, a slow-paced pedestrian street, and Peachtree, a busy, vehicle-heavy four lane road - which offers opportunities for unique street fronts and views. The housing design is primarily explored through an in-depth study of community dynamics, from the unit level to the neighborhood scale.

Sequences

Morning greetings in front of unit doors

Conversations under a portico, hiding from strong evening sun

Vertical sequence of community ranging from the public porch to the outdoor resident’s patio, all the way to the private units.

Horizontal sequence of community from the cafe to the covered portico linked together through a center resident courtyard.

Air movement across the unit from street to patio, patio to courtyard, and vice versa

Openings allowing natural light in the entire unit, even in the darkest center through a light well

Aggregation of 4 units to form a shared patio for active resident exchange

Arrangement of unit clusters to divide up the building for light penetration and air circulation

Unit aggregation variation for larger communal spaces for residents

Center courtyard for community engagement in the neighborhood level

Unit Experiences

Terrace doors fully open to extend the dining and living area, forming a shared terrace, encouraging communal dinner and activity with neighbors

Light wells allow natural light to enter into the darkest core of the unit

Large bedroom windows with glass railings act as a soft extension of the balcony experience

Exterior balconies face either the street or inner courtyard providing a green view to every unit

Typical Floor Plan

Site Context & Ground Floor Plan

In between Broad Street and Peachtree Street is a 28,000 sqft surface parking lot that is ready for development. There are two sides sharing party walls and two street fronts wanting different design strategies based on the street’s characteristics.

Pocket Park

There are two pocket parks planned across Broad Street that may be used to extend the visual and physical connection from Nelson Street, all the way to Peachtree.

Broad Street

Planned to be a pedestrian street with limited car access, small boutiques, cafes, and resteraunts are anticipated, creating a slow-paced and active atmosphere.

Broad Street Elevation

Peachtree Street Elevation

Walking along Nelson St., crossing Forsyth, and through the pocket park, pedestrians arrive at the Connector Plaza. It is the endpoint of a continuous path leading to Peachtree St., a major road going through Downtown Atlanta. Although some areas of the plaza are designed to be enclosed at night, it is fully accessible to the public during the day, offering a spacious green respite in the midst of a bustling city.

Chaistain Ecovillage & Senior Cohousing

Year: 2022 Fall Senior Studio

Instructor: Heather Potts

Project Site: Chastain Park, Georgia

Site Dimensions: 268 acres (Eco-village) / 6.5 (Senior Co-housing)

With the goal to re-design Chastain Park located in Georgia into a sustainable community, a collective ecovillage is designed. Site division and planning is guided by policies formed by four departments - zoning & policy, transportation & infrastructure, urban design & public space, social services & community development. The unique characteristics of each development contribute to the formation of distinct neighborhoods.

Z2 - Residential District

Z3 - Recreational District

Z4 - Industrial & Environmental District

What is an ecovillage?

An ecovillage is an intentional, traditional or urban community that is consciously designed through locally owned participatory in all three dimensions of sustainability (social, economic, and environmental) to regenerate social and natural environments.

Chastain Park

Chastain Park is a 268 acre land with a golf course that takes up the majority of the site. It is mostly surrounded by single family residential buidlings. Each parels of the single family houses are fairly big for it is located in a rich neighborhood. The park still has a close proximity to commericial and office buildings that follow along Rosewell Road.

Cars are used as the main transportation system and public transportation is not easily accessible on the site, thus requiring a new Marta bus stations and safe pedestrian roads for the newly designed ecovillage that aims to promote walking.

Tranquil Playground, located at the quietest place of the entire site, is a residential complex for community-dwelling seniors. There are a total of nine residential buildings with flexible units that can be adjusted according to residents’ change of needs.

The residence is close to a stream of water and surrounded by an abundance of greenery that provides great auditory stimuli, visual comfort and relaxation.

Each apartment has its own greenhouse that residents could utilize to grow plants, vegetables or fruit for them to consume. It also has its own rooftop playground, each with a unique theme (e.g., minigolf, movie theater, campfire, etc.), in order to promote interaction with residents and frequent family visits.

A cafe is located north of the residence, providing employment opportunities for the retire and a communal gathering space for occasional events.

Froebel Block Housing

A Play of Shape Grammer

Year: 2020 Spring Junior Studio

Instructor: Thanos Economou

Project Site: Upper Yard, San Francisco

Site Dimensions: 87,000 ft2

Shape grammer is a formal analysis of geometry that defines a clear production system with shapes, relations, and rules. This design method utilizes simple shapes and rules to build various complex forms. With the inspiration from concept diagrams of the Free University Berlin designed by Candalis, Jones, and Woods, an affordable housing complex generated by shape grammer of froebel blocks is designed on “The Upper Yard” near Balboa Park Station in San Francisco.

Initial Shape Shape Relations

“The Upper Yard” is located directly across from Balboa Park Station in San Francisco. It is currently an unused parking deck with easy access to subways, trams, and public buses that connect to downtown San Francisco. The site is approximately 87,000 sqft, with an existing building located near the intersection of the Southern Freeway and Geneva Avenue, which includes a stairway leading down to the subway station.

Froebel Block Housing seeks to take advantage of these transportation connections by retaining the existing stations on-site and nearby. Acknowledging that the area is occasionally used by homeless individuals who sleep in their cars, the housing complex aims to provide a better temporary shelter for them and others, offering an affordable and supportive environment until they are ready to transition to permanent housing.

Unit Types

Shipping container construction is used to emphasize the modular nature of the froebel block inspired design and its purpose as a temporary living solution, while also promoting sustainable building practices. Each unit consist of two containers that are either connected vertically, horizontally, or stacked, forming three unique floor plans.

Project Site: Downtown Atlanta

Site Dimensions:120 ft x 180 ft

This project investigates Frei Otto’s wool thread technique that seeks to understand the complex branching structures formed by wool thread interactions. Surface, structural, and spatial qualities are all formed based on the resulting figures, configurations, and layers of threads.

String Slackness

Slackness linearly varied across the grid span

Slacker strings attracted to tighter strings

Effect of horizontal dipping & varying slackness

Vertical Dipping

Gravitational force acts parallel to strings; cohesion is strongest at the middle, where the strings are most slack

Clusters take on a rigid vertical form, constructed of basic figures

Clusters are formed from strings in their immediate radius of localization

Horizontal Dipping

Cohesion acts strongest at the middle and gravitational force acts perpendicular to the strings, both forcing them to interact with the strings below

Clusters adopt a fluid form with complex cross interaction with basic figures

Clusters are formed from strings along an axis, determined by the side the machine was dipped

Due to the surrounding buildings of the site, there are more times when the site is shadowed. To compensate for such conditions, the building’s form aims to maximize the amount of sunlight penetrating through the windows by slightly carving in the southeast side of the building and bulging out the other. The bulge increases surface area of where sunlight hits the site the most. The carve softens the pointed edge of the building, ultimately helping light to shine through easily.

Analyzing the wool-thread machine and the analogue model, similarities between thread interactions and dance movements are recognized. If dancers’ poses are simplified into curves, they resemble the figures and configurations found in the experiments. Also, the flowing surfaces are a lot like the fluid transitions of multiple dance moves. So adopting the building as a Contemporary Dance School not only emphasizes the fluid quality of each interaction, but also the general flowing form of the building.

Study of Material and Movement

Year: 2022 Spring Senior Studio

Instructor: Marrat Marisabel

Collaborated With: Byeonghun Cho

Materialized Affordances

Material and movement studies of plaster and balloons are explored through techniques of casting. The process of creating movements are documented with a newly developed notational system. The resulting plaster models are carefully photographed for analysis on their visual and formal qualities that offer various affordances that differ by scale and senses. These affordances are further developed into sequences - as shown on this page - that provide spatial flow and program.

The notational system uses two axes: the horizontal and vertical that signify the passage of time and simultanaity respectively. The notation for the placement of plastered balloons is specifically inspired by the Benesh system that “relies on an iconic visualization of the body placed within a horizontal five line staff” (Farnell, 154). In this system, plastered balloons are shown on a three line staff that considers not only the plaster model itself, but also the surrounding environment, viewing it as the body performing movement.

Benesh Notation System: Body Parts and Staff

The choreography of movements is designed by combining and intermixing the casting experiments. Movements are initially envisioned, and experiments are conducted accordingly. The cured models are photographed and sawed in half to reveal the dance of balloons inside the plastic bag with plaster. Not only does the notational system depict the flow of movement, but also the sequence of actions taken by the balloon and its environment. This choreography draws inspiration from Pas de Deux, a film that traces the movements of ballet.
