Outdoor winter humidity is high in Sant Adrià de Besòs.
Sant Adrià de Besòs is small but very fragmented: La Mina, El Besòs and La Catalana are three different building realities. In La Mina we work in PERI-refurbished blocks whose kitchens and bathrooms are still 1970s originals — the tiling lets go on the first sounding. La Catalana keeps low fishermen's houses refurbished inside while preserving the façade, so we coordinate any visible change with the council. Sea and river air force siloxane façade paint and stainless hardware. Kerb-side parking is usually possible, which cuts the cost of bulky-material jobs versus central Barcelona.
