Concept Design for Future Arc Competition



This was my unfinished idea for the Future Arc Competition for an office green building in Jakarta, the program suggested an office area of around 10,000 sq meters plus a water park of around 16,000 sq. m.
My concept was to integrate the 2 sub programs and transposition the areas mixing them and creating a more interesting office area that uses the water to contribute to cool the building.
Also the oversized slabs create enough shade in the areas exposed to the south and west while they serve as outdoor areas for the offices in the floors above.
The integration of the water park was an idea unfinished(I found out about the contest 3 days before the deadline) and in the final render you can only see the first intent to keep the fountains underneath the building.
Here I sumarize the process for this concept:
1. water park and office site juxtaposed the green mass defines the core of the building and its main suporting structure ( the rest of the building balances on this main support).

2. The red masses are the main circulations betwen floors. The small vertical cube includes the emergency exits and service elevator. The big diagonal cube serves as the main circulation of the building. This main circulation is one of the most interesting parts of this design for me, I'm going to make a post just about that feature but lets just say here that the idea of using a inclined plane instead of a vertical for the elevators has been in my mind for a couple of years but I never had the time to develop the idea in the past.

3. The lobby and main entrance floats (hangs) above the main fountain. I thought about making this more obvious to the users by including a see trough floor system in this lobby so people could see the water moving bellow them.

4. The skin of the building holds within the volume of space need for the main offices. Since I'm originally from a tropical country I know first hand how this massive glass buildings gain heat from the sun and how in our weather this is allways a problem. To avoid ussing active systems all the time I proposed that the floor slabs should be bigger than the space within the skin of the building, that way the overhanging slab creates a permanent shade specially in the south and west sides of the building ( If you have lived just above the ecuator you would know why...) this also creates an outdoor office area in the terraces of the upper floors.

Overall even tough the contest is over and I couldn't finish on time (3 days is awfully short time specially if you are working somewhere else) I'm happy with the unfinished product and I think I would try to complete it even if it's just for me.
Another concept for this same contest was this one:

the idea was a little more straight forward but the proportions of the building never worked for me so I abandoned the concept early in the first massing exercises, maybe for a house or smaller building I could kep the idea of the spiral slope.
Technical drawings will be posted soon.
