Between the Atlantic Ocean and the Douro River, Casa1015 is located in one of Porto’s typical narrow, winding streets in the lively Foz district. The conversion of the 19th century house was planned by Pritzker Prize winner Eduardo Souto de Moura. Historical awareness, attentiveness and architectural masterfulness have turned the building in need of renovation into a unique residential work of art. Contemporary architecture forms a liaison with the traditional architecture of the surroundings.

Situated on a narrow L-shaped plot, the casa consists of two building parts: a front building with a second floor added and a studio accessible via a patio. The front part of the building comprises two living rooms, a kitchen and two bedrooms (each with en suite bathroom). The third bedroom is in the studio, which opens onto the patio with large windows and also has a private courtyard on the opposite side. 

In Casa1015, exterior and interior spaces, open and closed areas merge into one another; skylights allow surprising incidences of light. Soft colours, natural stone and wooden floors, combined with the simple and elegant furnishings (some of the furniture is by architects Eduardo Souto de Moura and Álvaro Siza Vieira), create a relaxed, intimate atmosphere.

The house was operated until 2015 as a B&B under the name 4Rooms Porto and can be found under this name in many publications, it is now a holiday house with three rooms.

  1. It was a wonderful week’s holiday in a beautiful (clean and well-maintained) house in a prime location in the Foz district. What a pleasure to stay in this total work of art. The beach and good restaurants and shops are within walking distance, the city centre of Porto is also easily and quickly accessible thanks to the superbly developed public transport system. Nice hosts who provided us with lots of good tips. We will be happy to come back!

  2. Impressive property, wonderful use of space. The interior gardens allow for co-mingling of interior and exterior spaces. Foz district is quaint and well positioned to sea and river. Plenty of cafes, shops, and coastal views nearby.
    Beds could use upgrade. Some lights and television appliances did not work.
    Would certainly stay again, good experience. Perfect home base while touring Porto.
