Maita qualified as an architect and urban planner at the Federal University of Rio Grande do Sul (UFRGS) in Porto Alegre, RS, Brazil, 1974. After working as an architect and researcher at Núcleo Orientado para a Inovação da Edificação (NORIE) linked to the UFRGS post-graduated programme, she got a year-long scholarship from the French Government to study pre-fabrication and housing in Paris.
Back in Brazil, she started a practice in Porto Alegre with P. Granzotto and P. Cassiano, later working for Fabio Penteado, Teru Tamaki Arquitetos Associados S/C Ltda, Campinas, São Paulo.
After moving to the UK in 1984, Maita studied at Oxford Brookes University for the Masters of Science degree, Energy Efficient Building (now SBPD), and now leads the Sustainable Design in Context module on this programme.
Her dissertation was an analysis of performance for earth-coupling systems in Porto Alegre,
RS, Brazil, designed and built by the then UFRGS Professor Ennio Cruz da Costa. Maita has since dedicated her studies and work to the greater integration between Oxford Brookes University and several Brazilian Universities, in order to bring students and lecturers from all institutions together.
