A loft for children
The compact two-storey building offers a distinctive identity in
a heterogeneous urban environment and blends in harmoniously
with its surroundings.
The rectangular core is designed as a spatially open system. A
„filter layer“ consisting of secondary rooms, outer stairs and a
patio area with plants for shade from the sun and secure play
areas mediates between the interior and exterior space. Exciting
insights and views are created by open and closed façade
Functional Openness – Spatial Intimacy
In addition to the administration, a therapy room and a bistro,
the ground floor houses two group rooms for toddlers. The corridor
between the rooms is used as a play and communication
area between the groups. The play berths were designed to be
spatially differentiated and provide the children with opportunities
for play and a relaxation retreat.
In accordance with the specifications of the operator, a
spacious, open space was designed on the first floor, which
enables the free division into play areas and areas for creative
arts. The flexible furniture was specially designed to complement
the concept and provides the children with different
options for combination. Thus rooms and areas are (re)created
time and time again.
Due to the small size of the building lot, an reduced and flexible
das für 150 Kinder eine differenzierte Spiel- und Aufenthaltsqualität sicherstellt. Um das Gebäude herum sind geschützte Außenbereiche mit Lattenrosten direkt den Aufenthaltsbereichen zugeordnet. Im westlichen Gartenbereich gibt es eine breite „Spielstraße“ aus geschliffenem Estrich und 2 Sandkästen für 0–3, und 3–6 Jährige. Das Angebot wird durch einen multifunktionalen Grünbereich im Süden und einen Bereich mit Sitzsteinen und wassergebundener Decke im Osten ergänzt.
Due to the short construction period (six months), a rapidly
producible design was chosen: a composite construction of
in-situ concrete and prefabricated wooden elements.
The two-storey nursery which consists of the central structure
(22.00 x 22.00) and the secondary rooms as annexes is built
on a reinforced concrete slab with a circumferential ice wall.
The main structure has two different ceiling systems. The
ceiling above the ground floor is a massive in-situ concrete
ceiling (h = 28 cm), the wooden beamed ceiling (h = 12.5 cm)
above the first floor rests on a joist support system.
The additional rooms are made of laminated timber and are
horizontally connected to the main body. They direct their
vertical forces into the foundation slab.
The bracing of the building is achieved via a central core and
a wall on the inside stairs which are both of massive reinforced
The nursery was implemented as a passive house construction.
An air-water heat pump was installed on the flat roof for the
required heating load. During the summer, support cooling via
the ventilation system is provided through the heat pump.
The minimum required hygienic change of air is ensured by
a ventilation system with heat recovery and summer bypass.
The climate control of the entire building during the summer
months occurs through the ventilation system by cooling the
The passive house construction ensures the residual heat
supply during the operating time via the ventilation system.
The ventilation system is based on heat recovery with a cross
flow plate exchanger without moisture recovery and heating
and cooling coils.
