Text description provided by the architects. The Gramaxo Foundation, represented by the President of the Board of Directors, Ms. Maria de Fátima Gramaxo, intends to build a single-story building on a plot of land that it owns, implemented according to the attached topographic plan. The new building, the Headquarters of the Gramaxo Foundation, is intended to exhibit the family's artistic heritage, also featuring a room for temporary exhibitions and a multipurpose room with seating for approximately 100 people. The building is almost parallel to the existing granite tank, to be restored, and the tree-lined avenue that leads to the main residence, from the magnificent baroque gate. The current levels of the land are maintained. The pedestrian access path runs perpendicular to the avenue, along the northern boundary wall of the property. The loading and unloading access is parallel to the avenue, on the west side of the new building, from an existing path. Parking for 25 vehicles is provided next to the wall to the east of the avenue, with autonomous access gate, as indicated in the drawings. All rooms will be naturally ventilated except for: toilets, storage room, archive, pantry, and permanent exhibition rooms. These rooms will be mechanically ventilated. Mobility standards (door dimensions, spaces, and sanitary installations) will be respected.
