In Denmark at present, there are about 600,000 typical Nordic Villa built in 1960-80 where
the main residents are the elderly population. The aim of this project is to transform one
such 1978 Villa, situated in the sparsely populated Hillerød, into a modern and sustainable
home while still maintaining the original aesthetics through materiality.
To upgrade the existing single storied 4 – person villa to accommodate more inhabitants and
different households (e.g. single family, couple, large family with children and grandparents,
students); which would lead to future densification and upgrade of the suburbia as well as
promote long term living. To design a low energy house that rightly promotes a sustainable
way of living not only for the occupants but also ultimately, for the entire neighbourhood.
Based on some initial energy simulations and theoretical knowledge, a semi outdoor space
(shell) should lead to 1/3 reduction in energy consumption. It is an unheated space that acts
as a thermal buffer between the building (core) and the external environment and also
facilitates passive means of ventilation.
An initial LCA analysis has been carried out which dictated the reuse and recycle strategies
of the existing materials. Several conceptual designs and iterations have been undergone in
order to find the most optimal solution. Densification is being achieved by adding a second
storey and redesigning the internal spaces, leading to a total of 4 different apartments.
Energy efficiency is being achieved by introducing a shared, transparent semi outdoor
space. Utilization of daylight leading to reduced need for artificial lighting. Wood has been
used for the main structural system over concrete due to its good LCA profile; furthermore
LCA-evaluated and pre-fab materials have been proposed for the new design. Sustainability
is being further achieved by introducing a shared green roof and vertical farming urban
cultivation options, solar panels (PV and thermal), rainwater and greywater systems.
Moreover, the shared spaces would lead to more socialization and interaction between the
inhabitants, thus creating a sense of community.
The final design and results will be undertaken during the 3-week course period in June. The
final results should show a truly sustainable and energy efficient design with optimized
systems that also prioritize indoor climate and user comfort.
The project has been conducted as part of the Master course 11982 Integrated Design
Project F18 under the headline: Densification and upgrade of suburbia.
