Specifications & options

Quality assurance

Oppen is institutionally acceptable.

In the UK, the majority of commercial buildings are owned by banks and funds as investments. This has led to the standardisation of specifications which are acceptable to investors. Öppen, while being innovative, fully meets the expectations of investors.

Those who finance buildings, usually banks and pension funds, are rightly careful to ensure that they invest in buildings with a long term value. Öppen only uses tried and tested materials.


Öppen comes with a suite of warranties for the first 12 years.

Öppen complies with all UK statutory requirements and building codes.

Öppenhaus complies with all relevant housing design standards.

Soft landings

So that you get the very best use out of the building, Öppen provides help for the first 12 months to explain how everything works and to resolve quickly any problems that might arise.


Öppen is a truly sustainable building, well insulated and very accurately constructed to achieve very low air leakage. Many components are manufactured off-site, resulting in very low site waste. Öppen has exposed thermal mass for passive cooling, and high floor-to-ceiling heights for stratification. This height coupled with large windows provides deep penetration of natural light and ventilation. Fully adaptable to changing needs by design, Öppen’s carbon footprint can be amortised over 60 years.

Super low heat loss upgrade

As standard, Öppen complies with the already stringent UK Building Regulations.

Option: 25% or 50% increase in wall and roof insulation levels. Super efficient natural ventilation by Breathing Buildings.

Zero carbon upgrade

Through a combination of roof top solar collectors, thermal storage tanks, shallow ground source heat pipes and heat pumps, all powered by roof top photo-voltaic panels, the entire heating and cooling load of the building can be provided with zero carbon production. This upgrade must be used in association with an under floor heating system.


The external walls are fully insulated and clad in metal panels.
