Oásis Biosistema

Oásis Biosistema designs and builds natural swimming pools, ornamental lakes and gardens. Alberto Tassi founded the landscaping and ecological design company in January 2022, and it is headquartered in the Lisbon/Palmela area. The name comes from the old idea of the garden as an oasis: shade, freshness and a way back to nature. The work falls into three areas: ornamental lakes, natural swimming pools (Oásis Pond) and sustainable landscaping (Oásis Garden). No project uses chemical treatment. Biological balance comes from aquatic plants and fish instead, which supports local biodiversity, and the results are meant to look elegant. The pools and lakes function as living ecosystems rather than conventional treated water features. Oásis Garden covers regenerative, low-maintenance garden design suited to the Portuguese climate and to the local ecosystem. The company also builds outdoor wellness features: saunas, jacuzzis and quiet wellness gardens, private spaces made for relaxation and for time outdoors. The founding idea is to design with nature rather than against it, and to show that luxury and sustainability can go together. Each project is worked out with the client, to match what they want without losing the ecological side. Oásis Biosistema holds a construction licence (Alvará IMPIC nº 107069-PAR) and has over 25,000 followers on Facebook.
