Floating Nests
Project Idea by Architect Peter Stasek
The Loft London Farm Tower in the form of an
imaginary gigantic tree in whose artificial crown two big loft formations are
placed as floating nests. The vision of an unprecedented zest for life (joie de vivre) while, at the same
time, utilising the entire Metropolitan logistics.
The "floating nest concept" is based
on a high exploitation of the air space above the respective plot of land in
connection with a minimal impact on the available plot area. Even after the
implementation of the project, the unrestricted panoramic view over the Thames of
all neighbouring buildings will remain barrier-free to the greatest possible
extent, since the air space below the treetop reaches a height of 35 metres.
The treetop itself consists of three compact rings with a diameter of 100 metres
each, containing an mesh-type supporting structure clamped in-between on which
natural vegetation can grow. These three rings are fixed on supporting columns with
a height of 35 metres. Thus, the entire tree construction reaches a height of
135 metres in total. All rings are arranged at equal distances of 40 metres and
are situated on a longitudinal axis parallel to the river Thames. In the area
of the outdoor facility, there are only the supporting columns (abstracted boles)
integrated in the entire open space design. These columns not only assume the supporting
function for the treetop, but also the development function (preparation) of
the whole "floating nest community". Besides the staircases, the
columns comprise all necessary supply units as well as two elevators, which are
moving on their outer edge towards the treetop, following the outer edge of the
ring construction. This circulation around the floating nests outside the treetop
in free space represents an additional adventure for each visitor (or
resident). All elevator stations are connected with the floating nest levels by
bridges.
The artificial treetop not only assumes the supporting
and development function for the floating nests, but will also be used as an
important agricultural area for vertical farming. As a result, e.g. algae can
be produced (for biopetroleum) within predefined organically shaped net
constructions. Supply and maintenance of these agricultural facilities will be ensured
by moveable bridge constructions, which are placed on rails between the rings
on their inner edges. An additional effect of this artificial treetop is the
creation of an oasis-like environment embracing the floating nests below a
transparent green screening. This enables every resident or visitor to enjoy
the entire panoramic view across London’s city centre. The floating nests as two loosely connected loft
formations are fixed with tie rods within the treetop realm in a floating
position. Each “nest” consists of 16 levels, which are shaped in the form of
gigantic green leafs. These leafs are staggered on top of each other. Their
natural leaf structure will be reflected in the floor segmentation as well as
the wall configuration of the individual levels. In this way, the midrib of the
leaves takes over the function of the longitudinal allotment corridor, the side
ribs take over the function of the lateral space boundaries and side corridors
respectively. All levels are developed by internal staircases, each of which is
positioned on the ring axis. The levels are connected to the rings by glazed
stair towers in the lower air space.The main utilization of all nest levels is
defined as a mixture of vertical farming and inhabitable loft areas. On the top
floors, there will be gastronomy and shops. A part of the underground parking
lot, which is situated below the entire plot area, will be available for all
residents and visitors of the floating nests.

Ecological awareness and sustainability of the
whole "floating nest" concept will particularly be ensured by using geothermal
energy for heating and cooling as well as by using thermal solar energy for LED
lighting (including ultraviolet radiation) for the supply of all agricultural areas.
