Approach from West

 These two sketches show the West facade, which will be crucial for the approach of the building. Most visitors will see this facade first. Since I use the "fiber" for the public components in my library, I decided to extend the organic shaped elements to the West facade to create a canopy over the public entrance. Visitors recognize by the facade which areas are public and which are private inside the library.

 

Circulation in Section

This section shows the circulation of public and private. There will be three public entrances. One is located at the West side of the "private building", which takes visitors directly to the fourth, sixth and seventh floor. The other two entrances (escalator and elevator) are located underneath the private building. Visitors, when entering the library from the public building, have the option to explore the building by using the escalators, but also use the bridges to enter the "private building" to participate for instance workshops in the computer lab or special showings/ presentations in the auditorium. After a presentation, the visitor may use the grand stairs in the auditorium lobby area to reach the top floor with the upper bridges which lead to the roof-top cafe. A separated entrance is dedicated to the librarians in the Eastern part of the "private building". 

Program in Section

This section shows a general distribution of the program within the library. The public building will house the stacks, collections, reading and meeting areas and a roof-top cafe. The private building will house the administration, a big computer lab, the auditorium and audio/ video labs. All spaces located in the private building do not necessarily need natural lighting and are somehow connected to computer technology, this resulted the particular distribution of the program.  

Sun Path Study

This sun path study shows the site with its context buildings, which are all on average 50 feet  tall, as well as the core of the "public building" which will rise to approximately 90 feet.  The red volume indicates the core.  Since the public building with its open and airy feel will house the stacks of the library, it is important to determine how the sun will penetrate the site.  I decided to raise the public building by 20 feet (as shown in my study model), which also means that the south facade of the public building has an unobstructed sun exposure at noon throughout the year.  As indicated in my study model, I placed the core along the south facade to create a "sheltered area" for the stacks north of the core. 

March/September 21 at 9am,12pm and 3pm

June 21 at 9am,12pm and 3pm

December 21 at 9am,12pm and 3pm

The core is also situated slightly east to accommodate a slope that connects the roof to the upper bridge.

 

An additional reason for placing the core along the south facade is to ensure unobstructed views of the Brooklyn Bridge in the north. 

Facade Sketch

This is a sketch of how both building facades will look together. The lines on the "private" building will made of corten steel. It has a natural brown tone which will run into the horizontal elements of the "public" building and continue in a similar tone of wood.

Study model "Fiber" building

The first five pictures show the study model for the "fiber" building, which will house most public components of my program. Each floor has an open feel to it with virtually no distraction other than the core. Angled escalators create an intriguing way of circulation through the building. Openings in the floor slabs, which "grow"/widen or narrow, create a vertical connection through the building.

 

The following pictures show the first approach of a facade treatment with organic flowing horizontal elements. The vertical elements tie the horizontal elements together and give the facade the irregular feel like single fiber strains in a piece of paper.

 

Facade development

This is a study of the facade of the "private" building

 The shaded areas indicate a setback in the facade. The white areas will cantilever and are primarily means of circulation through the building.

The Area with the layered line indicates the auditorium. Additional setbacks occur on the West side to break up the facade.

The lines terminating in circles indicate the means of circulation. 

The circles indicate the continuation of the circulation within the building.
