The roof construction on top of Ungdomsvillan is  up.  This is where the Soltech solar system will be installed.

Per Nyström, the founder of NyFam in front of the freshly installed Nordic green wall. This is the first of its kind when it comes to green outdoor walls in nordic climate, and will be tested on top of the terraces during the coming year.

Sven Jacobsson from Strandved, discussing construction solutions with Magnus Johnsson, from Bjerkings.

Larissa Nielsen is planning the site for the Voltair ventilation and heat exchange system with Eric Helmenius & Thomas Franden från Kraft och Kultur.

David Gard, the chef who will later on run the restaurant is grilling eco-sausages for the construction crew.

Icopals NoXite roofing is getting installed on the low roof. Noxite contains titanium dioxide granules, that interact and remove toxic nitrates from the air. The titanium also gives the roof a whiteish color that will reflect the sunlight and keep the building and the city a little bit cooler…

The loft is coming up inside the structure. Up there a conference room, a preparation kitchen and a bathroom will later be constructed.

The building frame, and some insulation.

Gotta keep the hardening surface from cracking by keeping it wet. Leif our in-house constructor and carpenter waters the newly poured terrace floor.

Surface work on what will be the floor of the restaurant building.

Fredrik the project leader mixes some cement in order to patch up a few of the pipe holes in the original roof. Preparations for the next part of the base plate.

The Penetron concrete is self sealing and water proof. if cracks emerge in the hardened concrete the special penetron compound will crystalize and seal itself tight. This is to prevent leakage down to the offices below.


Swerock arrives with the Penetron concrete mix..

the re-bar covers the whole main terrace, and mold-walls is installed. the penetron concrete will be poured in two occations. One thicker layer for the building and later one thinner layer for the terrace.

the Combimix crew advancing on the parkside construction..
