T4 Duplex – Investment Opportunity Next to Avenida da Liberdade

Just 2 minutes from Avenida da Liberdade and 5 minutes from Praça dos Restauradores, this duplex offers one of the rarest combinations in central Lisbon: a T4 with private outdoor space, independent entrance, and multiple revenue paths.

Currently configured as a student residence, the property generates an annual income of €30,000, with stable demand due to its prime location.

With an estimated investment of ~€30,000, the layout can be transformed into a high-performing Airbnb with a garden and mini-pool, increasing potential income to €50,000 per year.
(You can view the neighbour’s finished garden in the last photos.)

For long-term strategic investors, the property includes an approved preliminary planning document (PIP) allowing construction of up to 4 floors.
A full redevelopment project is estimated at ~€500,000, opening the door to a rare opportunity to create a custom home in the historic centre — with 2, 3 or even 4 floors, garden, and pool.

Whether you’re looking for a high-yield rental asset or a redevelopment project in one of Lisbon’s most coveted areas, this property offers a level of flexibility and upside that is increasingly hard to find.
