The aim of Berlin-based project developer MREI was to transform the concrete architecture that characterises the cityscape into a vibrant creative cosmos for work, enjoyment and encounters. In line with the principle of ‘rethinking instead of demolishing’, the existing shell structure was to be largely preserved as a valuable storage unit of grey energy and only supplemented or cut back in critical areas.
Against this backdrop, “Kalle Neukölln” has now been created on a total area of around 40,000 square metres as a future-oriented environment full of diversity – with flexible office and retail space, a large hall for hospitality, events and an indoor food market, as well as a green roof garden.

Optimised Saint-Gobain glass for the facade
Around 4,000 m² of highly selective Climatop Cool-Lite Xtreme solar control glass from Saint-Gobain Glass was used in the construction of the facade.
The Triple insulating glass in formats of up to 2980 x 3490 mm was processed to exact specifications by Doering Glass (Radeburg) and delivered just-in-time directly to Berlin's densely built-up city centre – a total of 1330 elements with a total area of 3592 m².
The high-performance glazing impresses with an extremely high light transmission of 70% and a very low total energy transmittance (g-value) of 0.33. This means plenty of daylight with minimal heating of the interior spaces.
Some of the glass panes were additionally equipped with special SI films to meet the high acoustic requirements in the inner-city environment.
‘Cool-Lite Xtreme 70/33 combines high energy efficiency with architectural aesthetics – and meets the highest standards of sustainability, comfort and functionality. It was therefore the perfect choice for Kalle Neukölln,’ explains Sylke Baer, Key Account Manager at Doering Glass.
