The future of one-family houses brought to life in a prototype house in Luxembourg. It is the result of three years of development and cooperation with a number of partners. With the support of the Luxembourg Ministry of the Economy, the support of Neobuild, Newconcepts and the H Tudor Public Research Centre and in partnership with the companies Dupont de Nemours, Bosch, Saint-Gobain Glass, Home Eos and Peintures Robin, the Luxembourg-based wood construction specialist Naturhome SA has designed Ncube, a highly industrialised approach to construction which is used to build passive one-family houses which are AAA-rated (mandatory standard for new builds in Luxembourg from 01/01/2017) and AAA+ (energy-positive house from 01/01/2019) as well as well-equipped and finished, all on a modest budget.
REDUCING COSTS WHILST INCREASING PERFORMANCE
By bringing together at the construction site the 2-D prefabricated walls and self-supporting 3-D modules which are fully fitted out in the factory (international patent pending) and making use of innovative materials and equipment, it is possible to provide a home which is cutting edge in terms of its thermal and acoustic performance whilst remaining affordable.
AN ONLINE CONFIGURATOR
The inspiration for Ncube is drawn from the production and organisational practices of the automotive industry. This also applies to its marketing: an online configurator allows the potential builder to design their future house and to get a price for it immediately.
The Wincrange "Living Lab" is a house which has been built using the techniques of Ncube. It will be lived in and fitted with sensors. Neobuild will monitor its thermal and acoustic performance throughout the year, along with variations in moisture and VOC levels. The purpose of these measurements is to confirm the laboratory results in a real-life environment.

3rd part certified
Neobuild S.A., Technology and Sustainable Development Innovation Hub, was set up in 2011 by the Council for the Economic Development of Construction (CDEC). As the only hub of its kind, Neobuild has two main missions. The first is to promote innovation amongst all stakeholders in the sector.
Other consultancy agency
The Henri Tudor PRC contributes to Naturhome's Ncube project (RDI draft law) in the commercial production and site planning stages. The Centre's contribution involves providing examples of lean manufacturing techniques for the construction sector.
Owner approach of sustainability
The Ncube modules are made solely from panels of laminated PEFC-certified wood, produced from wood taken from sustainably managed forests. The use of an amount of solid timber inside houses constitutes a significant additional carbon sink. The concept itself, which greatly reduces the amount of traveling for craftsmen to the construction sites, reduces the amount of grey energy involved in building houses.
A typical Luxembourg house - plastered façade and pitched roof with natural slates - 3 bedrooms - 1 study - 1 bathroom - 2 WCs - 1 entrance hall - 1 living room - 1 dining room - 1 kitchen - 1 equipment roomhttps://www.construction21.org/luxembourg/data/sources/users/18/ncube-wincrange-version-extenso.docx
If you had to do it again?
4 houses have already been built using the new Ncube concept.
