That’s why we particularly value young people who have grown up with technology, and games such as Minecraft.

•​ Outboard design: rooms facing outdoors with toilets adjacent to the corridor.•​ Nested design: rooms facing outdoors and connected to corridor.

Toilets nested..The first option represents a trend in hospital design in which patient rooms are open and easily accessible from corridors, in order to improve staff-patient visibility and increase operational efficiency.Unfortunately, this in turn means that the toilets are located on the façade, blocking daylight and views out, and thereby interfering with design for wellness principles..

The second option, traditionally adopted in many hospital wards, locates the toilets adjacent to the corridors and places the patient area closer to the façade.Although this partially supports design for wellness principles with patients benefitting from the connection to the outdoors, the layout is detrimental to the staff-patient connection and operational efficiency..

The third option, preferred by Bryden Wood, arranges the toilets in a nested position between wards.

An excellent example of healthy architecture, this option fully supports design for wellbeing with beds open to both the façade and corridors.Increased capital cost: The additional construction capital cost can vary from 8% in the most optimistic scenarios (Passivhaus Construction Costs – October 2019) up to 25%..

Increased programme: Delivering a Passivhaus building can take longer.Quality control on site is extremely important, strategies for airtightness require careful sequencing and interim testing and workmanship skills need to be of the highest quality..

Skill shortage and understanding.There is a lack of large-scale builders who can deliver Passivhaus buildings.
