During the restoration of Quinta da Lila, the original architectural style was meticulously preserved while everything was carefully renovated. The "Yellow House" in particular, showcases the sophisticated architecture of its former owners and stands out from the typical quintas in the region. Sustainability played a central role: cork insulation, Biocal plaster, 100% electric heat pumps, and solar hot water are just a few examples. High-quality outdoor furniture from Fermob minimizes maintenance and replacement needs, while inside, many high-quality vintage pieces were used to avoid new production. Custom-made beds, wardrobes, and other furniture were crafted from durable woods by a local carpentry workshop. All the stone used in the exterior was either sourced from a quarry just a few kilometers away or recycled, for example, for pathways and terrace walls.

The entire Quinta da Lila team is from Monchique and directly supports the local community. While membership in the "1% for the Planet" program was considered, the focus so far has been on supporting local initiatives that directly benefit nature and the people in the surrounding area.

The houses are heated with 100% electric heat pumps, and hot water is supplied by a solar thermal system. The roofs are insulated with cork – a local, CO₂-storing material that provides excellent insulation. Biocal, a natural clay plaster, allows the walls to breathe, and UVC filters in the pools ensure clean water with minimal chemical use. No herbicides are used in the vineyard; weeds are removed by hand or with a mower. Personal care products such as shampoo and shower gel come from 8950 Cosmetica, are 100% local and almost entirely chemical-free. Furthermore, the Quinta participates in the "Corredor Verde" program, protecting the landscape from invasive plants, planting native trees and shrubs such as olives, cork oaks, and holm oaks, and thus actively working to preserve nature.
