Aquatic plant nursery
Refúgio Botânico creates high-quality, clean, 100% chemical free ponds and natural swimming pools, using a variety of techniques that are all based on the principles of natural filtration to ensure year-round water quality. We combine mechanical and biological filtration to recreate a functioning, healthy aquatic ecosystem in the space of your own garden. Aquatic plants and microorganisms work together in constructed wetlands or external filters, using technology to bring out their best ability to create crystal clear, sparkling ponds and pools.
The price for a natural pool depends on its size and the required filtration system. The filtration system determines the desired water quality. The level of automation, which decreases manual maintenance, also plays an important role: efficient water circulation that gets rid of debris settling on the bottom, skimmers that clear away falling tree leaves and other floating particles, automated top-off that compensates for water loss due to evaporation, and efficient landscaping of the surrounding area are all major techniques in keeping a pond clean without spending time doing it yourself. Lastly, availability and transport of building materials set the price. As an indication, prices are around 1200€/m2 including IVA for a standard sized 75m2 natural swimming pond. Above 100m2, prices per m2 drop. Prices for a natural ecosystem pond range between 120€ and 245€ per m2.
Different from a retail nursery, Refúgio Botânico provides integrated planting solutions to make your aquatic ecosystems come to its fullest potential.
With a selection of 120 different aquatic plants to work with, we provide planting projects tailored to your pond or pool. Refúgio Botânico is not a garden center.
From idea to reality, this is how we do it
If you feel inspired to have a natural swimming pool or ornamental pond, you are welcome to visit Refúgio Botânico on appointment and see our show ponds and gardens in real life. It is an opportunity to get familiar with how ponds are best incorporated into the surrounding landscape, how maintenance routines work and to get a feel for the final results and see ponds that have been running for many years. The next steps to take from there are a technical visit to the location of your project, from where we enter the phase of quote and design. After both parties have agreed, we sign a work contract made by a lawyer that states guarantees and payment procedures, from where we enter the execution phase. Construction typically takes 10-14 days for a 75-120m2 natural swimming pool.
Conservation area
Since 2026 Refúgio Botânico has been classified as Biodiversity Reserve. The area, once an abandoned mix of maritime pine and mimosa forest, now occupies ten hectares of regenerating native deciduous forest in the valley along the Merceira stream. Key species that characterize the forest are Quercus pyrenaica, Viburnum tinus and Phyillyrea angustifolia amongst many others, with a rich undergrowth of annual and perennial herbs such as Ruscus aculeatus and Polygonatum odoratum.
