Rag Flats

The 3 photos above are of the Rag Flats project in Fishtown by the Onion Flats group.  These were the first LEED certified (gold) units built in the Philadelphia area.  Rag Flats is an experiment in and a critique of sustainable forms of urban dwelling. The former industrial Rag factory has been recontextualized as a residential garden community created by prototypical forms of dwelling commonly found in Philadelphia: the Row House, the Trinity, the Loft and the Pavilion. Rag Flats intentionally explores the necessary relationships between density, intimacy and privacy in any urban community.

Modular Twin homes
Achieved LEED for Homes Platinum Certification
Infill of a vacant urban site in a walkable neighborhood
R-30 wall insulation, including biobased foam, resulting in a 44% more energy efficient house than a typical development
Continuous insulation on the exterior to minimize thermal breaks
Use of environmentally preferred products with a high recycled content and/or rapidly renewable
Ground coupled heat/cooling pumps in combination with a short run ducted system and energy recovering unit to optimize energy consumption for heating and cooling
High efficiency plumbing fixtures for showers and sinks to reduce water and energy use
Collection of rainwater for use in irrigation and landscaping
MERV 13 filters to minimize indoor air pollution
Written durability plan and third party inspection to secure the quality of construction
40% fly ash (a waste product) was used in concrete to reduce CO2 emissions
Lush, native landscaping plan with rain gardens for on-site storm water management
Durable exterior materials that reflect and respect the existing surroundings of Chestnut Hill
These 1913 sf green twin homes were developed for Woodward Properties in Chestnut Hill to add to their portfolio of premier rental properties in NW Philadelphia. In addition to providing tenant amenities such as abundant daylight, modern design, and low utility bills (modeled to be less than $160/month total utilities), the homes prioritized the importance of flexible floor plans that would allow tenants to age-in-place. Strong indoor-outdoor connections were also provided through a series of balconies, porches, and terraces that retain privacy on a small, urban site. Given the proximity of the homes to the bustle of Germantown Avenue, careful consideration was also given to sound attenuation which was achieved through landscaping and super-insulation of the homes. During construction, many neighbors wondered how the homes were built so quickly; the cores of the home were constructed off-site in modules and then shipped to the site for finishing by Gardner/Fox. All team members were excited to see how quickly these homes were leased!

Urban infill project
Use of light wells and creative design to optimize daylight on a narrow site
Geo-thermal heating and cooling
EnergyStar certified, modeled to perform 45% better than a typical code compliant home
Water conserving fixtures, such as dual flush toilets
Energy saving light fixtures
Rooftop decks with green roofs to decrease storm water runoff and reduce cooling loads
Secure bicycle and trash storage at grade for easy access
Use of reclaimed materials, such as the exterior brick
Use of materials with high recycled content, such as the roof deck pavers made of recycled car tires
Use of durable materials, such as aluminum clad windows and cementitious paneling
1 year free PhillyCarShare
2 new PhillyCarShare pods on block
Bancroft Green is the redevelopment of a large urban parcel into ten townhomes with a central greenspace and PhillyCarShare parking area. With lots less than 16? wide, the design took a creative approach to daylighting and incorporated light wells and high windows to successfully bring light deep into the units. The project also took advantage of the small lot sizes by using party walls to create more energy efficient envelopes. Both the use of geothermal heat pumps and modular construction demonstrate that these technologies can be accomplished on even the narrowest of city streets. The final EnergyStar HERS rating for Bancroft Green projects that the homes should perform 45% more efficiently than a typical code compliant home of the same size.

100K house Project

link toPostgreen's flagship project, the 100k House project consists of two homes in the E. Kensington neighborhood of Philadelphia. The homes are very close to being finished and are both slated to achieve LEED Platinum certification. This project is Postgreen's first crack at the Passive House standard. It consists of two adjacent row homes, one of which is known as the M&M House and the other the official Philadelphia Passive House. 

link toarticle on Dranoff Properties LEED-certified five-story apartment complex at 777 South Broad St. The complex will feature 146 contemporary loft rental apartments, along with retail and restaurants on the ground level. The property was previously occupied by boarded-up homes and a defunct hospital. 777 South Broad is Dranoff's first foray into LEED building, so the company sought to verify the quality of new or unfamiliar green products before installing them into the units. A mockup apartment, erected at the developer?s headquarters, allows the staff to verify LEED credits and, perhaps more important, run tests on products.

The Spite House Northern Lierties



Similar to other "spite houses," the townhouse in Northern Liberties is built on a tiny, narrow and oddly shaped - almost unbuildable  vacant corner lot in the Northern Liberties (NoLib) section of Philadelphia. The NoLib Spite House doesn't quite follow the rules of its urban context, but rather seeks to recover them through a revelation of ordinary conditions. The house was influenced by the writings of Stanley Rosen especially The Elusiveness of the Ordinary, 2002.

The form of the building responds precisely - but not literally - to a series of specific conditions in the urban context, i.e. extending a street wall, establishing a corner and stepping to adjust to surrounding building heights. The primary architectural element of the building is a brick wall with windows and doors; but in contrast to the red brick front facades on the surrounding buildings, the brick of the Spite House is a smoke-stained dark gray color and the wall folds around the corners to wrap all three sides of the building.  Although the folded brick wall is not parallel to the sidewalk or the property lines, the two street walls of the corner are held (more or less) along the perimeter.

Like the surrounding buildings the Spite House has secondary elements that contrast with the brick wall. Unlike the painted wood and aluminum siding used on the secondary elements of the surrounding buildings, these elements are zinc.  Like those on the surrounding buildings these secondary elements act to provide a meaningful articulation with regard to the legibility of the urban context, e.g. marking an public corner and a private entrance.  Although at first glance the Spite House doesn't appear to be a ?good neighbor,? the bending of the brick wall along with the bumping of the secondary zinc elements provides a sense of belonging to a specific urban context. 

The interior of the house was developed around a vertical journey culminating on a roof deck with an upper-level green roof.  The journey begins on the sidewalk by crossing a stone threshold and stepping up onto a vestibule. The vestibule is positioned on the middle level of an interior topography. One steps down from the vestibule into a sunken living room or up into a raised dining room and kitchen.  From the vestibule one ascends the stairs on a vertical journey that passes through the bedroom levels and ends by breaking the roof with skylights, a roof deck and green roof.

The geometry of the exterior of the Spite House is resolved spatially on the interior in a manner that creates rooms of appropriate definition (with regard to shape and size) and specific outlook.  Rooms are seen as opportunities to occupy positions within the house in relation to the surrounding city. Each room is defined by the bending of the exterior wall and the bumping of the secondary elements. These exterior elements are inhabited on the interior as the narrative of the vertical journey unfolds and the intimacy gradient of dwelling is revealed.

GREAT NEW Listing Monday Oct 5th! 395,000.. PENDING
Designed to maximize space and light, this home has had every detail carefully planned and executed. The open floor plan of the 3 bedroom, plus den, and 2 full bath home is enhanced by its strong connection to the very accessible outdoor spaces. It is located in one of hottest and fastest appreciating neighborhoods in Philadelphia, only a few blocks from Passyunk Square and the heart of the Italian Market, with so many shops and restaurants just a short walk way. The home was designed by Scott Larkin of Brawer & Hauptman, Architects with the intent of maximizing natural light into the house. Originally selected in part for its southern exposure, the home takes advantage of the sun?s natural path. Partially frosted windows provide privacy from the street without light obstructing window treatments. Interior frosted glass doors, open riser stairs, ? height walls and 9? ceilings allow the sun to shine into the full depth of the home. The 3 levels are tied together with exposed brick, American walnut, built in wall pockets and steel stairs. First floor living room, breakfast bar, kitchen and dining room flow together as one space. Access to the outside is provided through a glass garage door allowing the interior to blend into the side yard creating an additional exterior room. The 2 second floor bedrooms are connected by an open sitting area at the top of the stairs. The sitting room can also function as a flex bedroom with its integral fabric partition and recessed pocket. The second level also features a full room shower bathroom. The 3rd floor is dedicated to the master suite. Sleeping area, desk space, walk-in closet (with washer/dryer hook up), full room shower, soaking tub, vanity toiletry display, mini fridge pocket, and roof deck are all integrated into the design. Come see this unique and very special home.




Latimer Street House, 1993-1994 David Slovic Associates

"The house designed by the husband and wife principals of the firm for themselves and reflects their philosophy of architecture and urbanism. The  home attempts to bring the amenities of suburban living to an urban setting.
The site was previously occupied by three row houses demolished in the 1940's. It is unusually large for a single family house and has frontage on three streets.  The house is organized around a courtyard which divides the building into two sections. Interior spaces reflect the simplicity of industrial lofts, opening to the courtyard through a wall of glass and steel.
Every aspect of the exterior exaggerates its difference from its neighbors. The inward focus of the plan reduces the ned for exterior windows resulting in facades of large blank wall surfaces. Not only is the house different from the traditional row-house but is also abandons the post-modern interest in ornamentation in a style that combines elegant materials and details with stark industrial simplicity." This information is from th second edition of Philadelphia Architecture a guide to the city by the Foundation for Architecture in Philadelphia.
