In Biarritz’s Golden Triangle, a stone’s throw from the Hotel du Palais and the Grande Plage, lies a magnificent Basque house with strong character, offering approximately 320 sq m of gross floor area and significant renovation potential with several layout options. The town hall may authorize mixed use (residential and/or commercial), an attractive opportunity with two possible projects. The first project—an architect’s proposal—is a house spread over three levels. The living area could reach 210 sq m and include an entrance hall, a triple living room, a large dining room, a kitchen/dining room, a laundry room, a pantry, a grocery area, a gym/cinema room, and a wine cellar. Upstairs, a sleeping area of approximately 90 sq m could accommodate four master suites with dressing rooms and bathrooms, for a total of five toilets. The exterior features a beautiful terrace accessible from the living area and a 40 sq m space in front of the house. A 45 sq m double garage can accommodate two large vehicles as well as motorcycles and bicycles. Second project – business conversion: possible transformation into commercial premises (previous use), with a flexible space suitable for offices, a high-end gym, a medical practice, a guesthouse, etc. The strategic location and available space make it a sound investment for both commercial and heritage purposes. Personalized support for financing and renovations (broker and architect) is offered. Energy Performance Certificate (EPC) not required. Heritage investment, prime location.
