Casa da Flor, Heritage house in São Pedro da Aldeia, Brazil.

Casa da Flor is a residential house in São Pedro da Aldeia decorated with mosaic patterns made from ceramic fragments, seashells, tiles, glass pieces, and recycled materials covering the walls, floors, and furniture. The entire structure displays three-dimensional arrangements of these collected objects integrated into the building itself.

Gabriel Joaquim dos Santos began the house in 1912; from 1923, after a dream, he gradually added objects found in rubbish—ceramic, crockery, glass and tile shards, burnt-out bulbs, shells, chains, metal lids and car headlights—forming flowers, leaves, mosaics, grape bunches, columns and sculptures inside and out. He worked until his death in 1985. In 1987 the Sociedade de Amigos da Casa da Flor was founded to preserve the house and his work.

Gabriel Joaquim dos Santos began adding found objects to the house in 1923 after a dream; he fixed broken bulbs, shells, chains, metal lids, pipes and car headlights inside and outside, forming flowers, leaves, mosaics, grape clusters and columns. Researcher Amélia Zaluar lived alongside him from 1978 to 1985 and titled her monograph "A Casa da Flor – Tudo caquinho transformado em beleza".

The house stands in São Pedro da Aldeia, in the Lakes Region of Rio de Janeiro state, and is cared for by the Instituto Cultural Casa da Flor, the nonprofit set up in 1987. Visits are arranged through the institute, so confirm access before travelling. The decorated rooms and courtyard are seen on foot, and the mosaics cover both interior and exterior walls.

The creator systematically collected waste materials from his surroundings and developed his own method of integrating objects directly into the building structure over many years. This approach makes the house distinctly different from other buildings in the region, standing alone in its execution of this particular vision.
