Text description provided by the architects. The Gramaxo Foundation, represented by the President of the Board of Directors, Mrs. Maria de Fátima Gramaxo, intends to construct a single-story building on land it owns, as indicated in 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 a seating capacity for approximately 100 people.
The building is situated 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 ground levels are largely 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 from an existing path on the west side of the new building. Parking for 25 vehicles is planned next to the wall to the east of the avenue, with an independent access gate, as indicated in the drawings.
