Design Concept This project is focusing on creating a 1-2 person moveable wood cabin that is environmentally-friendly and with a small footprint. The design of this wood cabin will mainly focus on minimizing material use, creating connection between indoor and outdoor space, optimizing natural daylighting, ventilation and passive heating/cooling.

Step 4: Function - spaces define functional spaces, finalize indoor circulation, maximize natural ventilation, daylighting and passive cooling

Site Analysis

GREEN + + CELL is a creative co-living and co-working community that is based on modular design, and the form of building was inspired by cell proliferation. The project attaches on the existing buildings which are unprosperous shopping mall in downtown Tianjing, China. The intention of this project is to not only increase the occupation of those underused public building but also provide a vibrant urban park.

Cell division is the major inspiration of the design. Adopting the concept of cell proliferation, the project creates comprehensive spatial composition by duplicating simple modules. 2m x 2m is the minimum dimension that alowing comfortable human activities based on our research. We further developed 2m x 4m and 4m x 4m modules to accommodate variety of activities.

3 BRADBURY ST, LONDON PROJECT III

A new landmark to revive a cultural square in London, Mix-used building / 2 shopfronts + 4 apartment units = 8,000 sq. ft.

Site Analysis In 1993, Bradbury St. was first deisgned as a cultural center by HCD Architects in Dalston district, London, and it has became the majore cultural and event center in Dalston district. Until recently, Gillett Square is facing lacking visitors on non-event days.

England A10

The purpose of this project is to design a mixed-use building to replace a corner building at Gillett Square, so the new building will act as a social platform to bring more people to Gillett Square on non-event days.

Site History 1993, HCD Architects proposed and sketched the first design of Gillett Square on Bradbury St..

1999, HCD Architects added 10 market kiosks along the south side of the square. It has became the major social and event center of Dalston since then.

1990-Present, the corner building of the Gillett Square is now poorly interacting with the surrounding, and it need to be updated to provide a better social gathering space at the Gillett Square.

building enclosure failed slow repair/re-build

In 2017, Hurricane Irma made a landfall on Cudjoe Key, Florida, and houses and public infrastructures were severely damaged.

Besides the tremendous damage that was done by hurricane Irma instantly, repair and rebuild processes were major issues on the island due to limited building materials, lack of construction workers, arrangement of reconstruction schedules and also financial reasons.

This project focuses on providing a creative solution to solve the complicated aftermath of hurricane damage, and it also brings a critical insight into human relationships with physical landscapes and environments in the face of changing climates and extreme weather phenomena that increasingly affects our habitats.

Structure damage on Cudjoe Key (2017, hurricane Irma)

43.6% percentage of total house numbers

Design Approaches

Stable & Durable In order to survive from strong wind and also debris, building structure need less individual connections as well as more contact surfaces between each connection.

Fact

Density

Research

In each year, at least 8.8 million metric tons of plastic waste are dumped into ocean

Fiberglass - 0.05 lb/in^3 Plastic waste - 0.03 lb/in^3 Steel - 0.28 lb/in^3

Pound for pound, plastic-fiberglass is stronger than many steel members, and weight more than 50% less. (*resource: Bedford Reinforced Plastics)

Prefabrication & Easy Assembly

On Cudjoe Key, households are still fixing their houses that were severely damaged in 2017 by hurricane Irma.

Pre-fabricated parts allows easy and fast re-construction after damage.

Connection Diagrams

Structure Design Diagrams

Inspired by fiberglass boat manufacture, connections are bolted and seamlessly glued together, which forms building enclosure.

Plasctic structure layers are extruded from molds, and extrusions are reinforced with fiberglass layers in order to withstand hurricane.

Structure Geometry Analysis Structure ribs are constructed with arch and triangle shapes, which are not only strong but also aesthetically elegant.

Golden section proportion was applied to define non-structural parts. There is 15’ 7” wide customizable wall parts with range of 7’ and more of head clearance on each wall panels.

Non-structural parts of wall is highly customizable

Construction Diagram By standardize building components, buildings are expandable at different time and phases for different use. At the same time, building parts can be easily changed or fixed after been damaged.

With the increasing use of plastic, human influence has become a serious issue to marine life. The characteristics of plastic make it hardly degradable over time. But it is possible to reuse and recycle plastic materials by changing its forms physically.

Pushing the boundary of comfort is risky, but it can also be the most rewarding. By using familiar technologies into a new field, the risk of failure could be minimized while the rewards are potentially tremendous, and that’s where innovation takes off.
