1. The Concept House project aimed to develop a sustainable house through industrialized construction methods. It was led by professors at Delft University of Technology with support from building companies and suppliers. 2. The project brought together various stakeholders including universities, building companies, and local governments. It sought to gain knowledge, conduct research, and stimulate industry through the development of innovative construction techniques. 3. The completed Concept House prototype in Rotterdam demonstrated an industrialized construction approach using prefabricated materials. However, the assembly process revealed integration challenges between the designs of different partners.

de TU Delft?
•
•
•
•
•
•
•
Onafhankelijk van practische sociale beperkingen
Onafhankelijk van economische beperkingen
Gelegenheid om zelf te bepalen wat er gebeurt
Gelegenheid om resultaten te onderzoeken
Gelegenheid voor derden om te zien en te leren
Gelegenheid om reproduceerbaar onderzoek te doen
Gelegenheid om de industrie te stimuleren

34. Technical evaluation
1
Transition traditional to IDF mindset
• Partner Unica used to measure bathrooms. Not necessary
anymore.
• Partner MdR was confronted with another steel building
sequence.
• Partner VDM had calculated 1500 KG for the bathroom.
This turned out to be 4000 KG, leading to many unexpected
adaptations.
• The Solarlux façade was not adapted for housing.
• The FAAY electrical wall channels were not tuned with the
timber building structure of VDM.

35. Technical evaluation
2
• Insufficient attention for flexibility, resulting in problems in
electrical installation.
• Flexibility lacked between floors and walls by partner Unica.
• The electricity channels in the floor not properly produced.
• The drawings of FAAY came too late.
• FAAY refused flexible wiring in the ceiling.
• Electric wiring in the façade by VDM became unattainable by
the outside ceramic cladding.
• Holes for toilets were not realised in the factory but on the
spot.

36. Technical evaluation
3
• The screws for mounting inner walls to floor were too long.
• Integration partner Niko (Home control) and Itho
(Autotemp) turned out to be impossible, because of
intellectual property.
• A decentralised ventilation system of Renson per room, was
taken at the last moment
• The architecture of the installation space had to be
changed dramatically at the last moment and improvised.
• Partner Unica was too late with detailing and drawing result
inefficient use of space.

37. Technical evaluation
4
• Rainwater drainage was forgotten.
• Partner Icopal ordered insufficient materials. Improvisation
is necessary.
• Partner VDM changes drawings, made by TU Delft. Partner
Justimax had to draw the cladding a second time.
• The holes in the ceramic tiles of partner Mosa were
wrongly drilled. 120 m2 has to be redone.
• Obsolete tiles could be returned to Mosa for recycling. But
the tiles went to a common waste processor.
• Consoles for the solar protection system of partner Renson
came too late. Causing extra hiring of aerial platform.

38. Technical evaluation
5
• The edge of the roof is not realized according to
drawings, resulting in improvisation.
• Inaccurate connection between the inner walls on the
structure of VDM were done by forbidden PUR.
• The ceiling was made seamless although industrial seams
were acceptable.
• Materials as the floor made installation dangerous and
troublesome.

39. Conclusions
1
• A step into sustainable building practice
• For cooperation between companies and universities is a
challenge.
• It is difficult to involve companies in futuristic developments.
• The strategy to build a complete house turned out to be
effective. All parties participated with a great motivation.
• The project disturbs the primary process of the companies.
• Parties are experienced better results.
• The change of project leaders at TU Delft gave instability.
• Necessary permission next steps of finance determined
further possibilities.

40. Conclusions
2
• Difficult to plan a project in changing.
• Experimenting and building are no friends.
• Difficult to mobilize knowledge at the university and to link it
to practical experience of companies.
• The culture at the university did not contributed to the
project. However the guts and perseverance happen to be
present in the chair holder Mick Eekhout.
• Politics form an important success factor. Not only the
product, but also the context is important.
• Concept House Village might be a useful platform just as
Booosting and Barba House.
