New Freedom Park Museum

By now most football fans know where is freedom park. The memorial of the victims of apartheid. The newly opened freedom park museum called HAPO meaning "The Dream" Designed by GAPP Architects + Urban Designers, Mashabane Rose Associates and MMA Architects under the collaborative office OCA.The vision of HAPO as a series of abstract boulders resonates with several traditional African ideas of healing, represents the rocky
African landscape and the spirit of traditional and indigenous knowledge systems.The four soaring “trunks,” containing ten gallery spaces that can be traversed in sequence as if they were fused into one.The museum unfolds as a historical continuum, a spatial journey of the struggle for democracy in apartheid South Africa. Glazed openings in the wall of the museum mark the ascent with framed views of the city and surrounding countryside below.Cracks and fissures of natural boulders changing over thousands of years are mimicked in the design of the windows with their deep-set openings and complex irregular shapes,permitting just enough natural light to reinforce the sense of a dimly lit cave.Internally the interconnecting boulders expand and contract providing exhibition spaces which lean and fold through the large volumes and compressed spaces alluding to the mountainous shelters of traditional healers live.The building’s curved exterior walls form a double layered enclosure that serves mechanical, structural and programmatic functions. The cavity space between the walls becomes an artery essential to the life of the building; providing space for air distribution and economical
passive heating and cooling systems, emergency egress, and for the
storage, installation and maintenance of gallery multi-media equipment
and exhibition fixtures. It performs as a sustainable environmental
control device, acting as a trombe wall during the winter and as a hot-air exhaust chimney during the summer.The wall is a double shell of concrete and masonry.The inner walls of the conical domes are a composite structure of reinforced concrete and infill brick masonry.The outer wall is made of two layers of brick sandwiching a 10 cm wide lightly reinforced concrete filled cavity. This outer wall is self supporting and tied back to the fins and slabs.
Clad in copper, the material’s malleability has provided the opportunity for
complex surfacing and furthermore allows the building skin to transform over time, slowly merging within the hillside. Copper is also particularly significant as an abundant material used to trade in Africa over thousands of years.
The oculi skylights are proposed as inflated pillows made out of self-cleaning ETFE (ethyltetrofluoroethylene film). This system will allow transparent colorless frameless skylights cleaned by rainfall and immune to air pollution and UV radiation.
