Capital Flats / Onion Flats

In 1999 Capital Meats, the former meat-packing plant which operated on this site for 80 years, was a sprawling mass of ravaged, collapsing, and abandoned buildings situated in the middle of a predominantly residential neighborhood. Onion Flats change all that. This once dilapidated site is now home to 8 dwellings that are rich in both history and innovative design.

Thin Flats / Onion Flats

This eight unit residential project explores the highly efficient and architecturally latent potentials hidden within the traditional form of the Philadelphia “Row” home. The vertical rhythm, regularity yet diversity of this most prevalent residential urban typology was the primary source of inspiration for this experiment. Thin faces fronting both Laurel and Pollard Streets mask and blur conventional lines of demarcation between all eight duplex dwellings both vertically and horizontally. In the process, a degree of density yet expansiveness uncommon to the thin space of the urban duplex emerges. The Philadelphia “Row” is by nature a long, thin slice of dense, sustainable, urban space, typically ‘light-deficient’ and insular at its core. Thin Flats questions this traditional ‘deficiency’ by spatially reconfiguring the relationship between the interior and it’s skin such that its ‘core’ is flooded with light and air. This skin also affords each room on the ‘periphery’ of the dwelling the ability to step outside, and yet remain within the skin. This project also is unique by being the first LEED-H Platinum duplex residences in the USA.

Rag Flats / Onion Flats

We were first introduced to Onion Flats by you, our readers. After posting our Architecture City Guide to Philadelphia we received numerous comments suggesting that Onion Flats’s work should be among the cannot miss list if you visit Philadelphia. We certainly agree. We chose to showcase their project Rag Flats first, but we will bring you more of their work in the coming days. Rag Flats is an experiment in and a critique of sustainable forms of urban dwelling. The former industrial rag factory has been re-conceptualized as a residential garden community created by prototypical forms of dwellings 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. Rag Flats was a collaborative design/build project.

Cherry Hill Mall Renovation and Expansion / JPRA Architects

The complete renaissance of Cherry Hill Mall has repositioned the center as an elegant, contemporary classic shopping/dining experience. Prior to the renovation, the Owner, Pennsylvania Real Estate Investment Trust (PREIT) recognized that while strong customer demographics existed, many were driving by the center to shop at competing developments. With the potential addition of a Nordstrom department store, the need for a major repositioning of the center was appropriate. As a result, the comprehensive renovation of the development included the addition of a 138,000 sqf Nordstrom, an additional 62,000 sqf of two-level mall GLA, a new multi-level parking structure, and the complete renewal of the interior mall, all while the center remained in full operation.

Surface Deposit: New Work by Lead Pencil Studio
Surface Deposit is the first Philadelphia exhibition of Lead Pencil Studio, a Seattle-based collaboration between Annie Han and Daniel Mihalyo. Extending from a traditional training in architecture, Lead Pencil Studio works across multiple disciplines to explore spatial conditions, material, and form through large-scale installations.
Surface Deposit is an exhibition of fragmented sculptural assemblages based on the analysis and research of digital data collected by a 3-dimensional laser over several months during the summer of 2010. Incorporating various materials, including remnants from Tyler School of Art’s former campus in Elkins Park, PA, Lead Pencil Studio will explore notions of accumulation through elements of architecture that are not inherent to a structure’s original design. Their practice is self-described as “architecture in reverse…our projects are everything about architecture with none of its function…spaces with no greater purpose than to be perceived and question the certainty posited by the man-made world.”
The exhibition will be open until February 26. More information can be found here.

Parametric Design to Fabrication Workshop
This workshop will introduce participants to the cultural, technological, and tectonic domain of parametric design and digital fabrication in a fast-paced and hands-on learning environment. Over the course of two days, the workshop will involve iterative prototyping and associative design strategies capable of incorporating and embracing an array of material and fabrication constraints. Participants will explore and construct highly articulated material assemblies through computer-aided manufacturing, mold making, and casting.
This workshop is the result of a collaborative effort between Studio Mode and Point.B Design and will provide participants with direct access to a full suite of manual tools for wood, metal, and plastics fabrication in addition to a 3-Axis CNC Mill. Instruction will be provided in the construction of molds, the proper handling of materials and casting, file preparation for working with the mill, as well as a series of parametric design strategies with supporting content.
