MegaFloor

MegaFloor


General outline


MegaFloor – definition of ‘MegaFloor’ is ‘ architecture composed of an extensive floor, where an OfficeCity is functioning on the concept of OfficeUrbansm.’ ( JA Vol.50 )

From Japanese theory refers to JA Vol.50, MegaFloor is a spatial idea for the 21st century architectural space adjusting new work / active style. Since cited research(*1) about at Sendai Mediatheque, the building considered as an example of MegaFloor. The intention of the idea is to support any kind of architectural development and to provide city space where people are expected to gather their information, knowledge to encourage effective productivity while the floor guarantees socially equitable opportunity for users. The idea is originally deprived from office building theory, but occasionally because of the nature of MegaFloor, it can be used for any architectural usage. This notion is tied with the idea to expand city space.

MegaFloor is comprised of five principles: Flat vast floor, Tall floor, Stout structure, Inverted core facilities, Surround ( social activities areas such as café, meeting room locates on floor rim. )

Terms


Office City

Office City is a place where a double entity ‘events’ and ‘objects’ that appears from interaction / friction between three layers : one is fundamental environment, the second is interface environment, and the last is activity environment.

Office Urbanism

Office Urbanism is a system composed of three factors.
1, Fundamental environment which is physical facilities.
2, Interface environment which is facilities satisfying all kind of demands from workers / users on megafloor. In addition, the
facilities realize interaction between users and fundamental environment.
3, Activity environment which is planner of the floor.

Five principles


Flat Floor

100 x 100 metres ( 10,000 sqr metres ) floor. This size stems from human limitation of visually perceived.

Tall Floor

Ceiling height is 4.5 metres which enables ordinary floor to be freed from planning common
sense/regulation in terms of distance from the windows.

Stout

A large span structure maximizing flexibility.

Inverted core facilities

Lift, pipes are dispersed around the exterior of building. This extends flexibility of the floor.

Surround

Social activities areas such as café, meeting room locates on floor rim.
