The Econef Children’s Center


Our vision — little means a lot.

At its core, sustainable architecture provides means that cater beyond basic needs to build a more sustainable future. The buildings of the Econef centre are meant to accommodate future possibilities, of a brighter future. Low-cost, low-maintenance construction and green technology were central to the design concept and integrated into the site plan.

A wider architectural goal is to empower the centre with increasingly self-sufficient, income-generating and maintenance-free processes and amenities which reduce the orphanage’s dependency on private donations long-term.

Collaborative construction

Vernacular architecture — building local environments to local needs — has been central to the research, design and construction processes. The skills of local builders are integral to the sustainable house typologies adapted to the northern Tanzanian climatical, cultural and economical conditions.

Exterior / Interior

The centre’s design is made to facilitate social interaction and strengthen a sense of community and family. Adjacent to the school and residential buildings, agricultural areas provide activity through cultivation of food, crops and animal husbandry, an important source for the centre to generate long-term income.

The placement and construction of the buildings and spaces are made with great consideration to local climate to optimise shade and cooling. Systems for natural ventilation have been integrated in the structure — perforations facilitate air circulation and welcome the evening sun to naturally illuminate spaces.

Layered metal sheets and sealing slurry have been used to waterproof the ceiling. Mosquito protection nets have been mounted behind local sisal pole. Finely polished ring beams accentuate the linear aesthetic and hold up the brickwork in case of earthquakes.

Materials

Local brick

By prioritising local and familiar materials we avoid excessive transportation costs; and prioritise local community of builders rather than rely on advanced masonry skills or costly external building expertise.

Sisal poles made from local wood

The wooden roof construction elevates the upper roof of corrugated steel to create air flow between the roof and the inner ceiling. The space between the two roofs is covered with sisal poles, made from hardy and durable wood readily available in the region, that helps prevent insects and birds from nesting below the roof. The inner ceiling holds a layer of thermal mass, protecting against the heat of the sun and the lower temperatures at night.

Sustainable solutions

Inspired by the tree of life.

Our economic use of resources and green technology have been strongly inspired by the majestic African baobab tree. A tree of life, it has long been a vital resource for local residents and the wildlife of the savannah due to its water retention qualities — holding up to 120,000 liters of water that enable it to the survive dry periods.

Much like the baobab tree, the Econef school buildings make economic use of natural resources. Rainwater is collected from the roof’s spine to then supply the showers, laundry facilities, and toilets. All grey and excess water is directed to the growth plots below. Solar panels provide electricity and waste residues are converted to cooking gas in a low-tech biogas tank.

Friends and collaborators

Econef is run by Caroline Nicholas, who has long championed for a brighter future for orphaned children of Tanzania. Her vision of establishing a children’s centre and school inspired the Swedish journalist Charlotte Lindqvist to help set up the non-profit organisation ECONEF and a Swedish affiliate. Together with Asante, a number of crowd-funding initiatives and events were organised to help Caroline double her original 14,000 sqm plot, expand the greenery on site and for the construction of the prototype “Baobaob” house to in 2013.

The Baobab house was finalised in 2014, and the Children’s Centre and school inaugurated in 2018. Next is a new library building set to be completed in 2020.
