Thanks to the recommandation of a former client PERSPECTIVE Paris was approached for his knowledge of the local market and french technics to help a foreign interior designer Olivier Dwek for a suburban triplex renovation in Neuilly sur Seine. The flat is composed of a groundfloor with private pool, sauna, gym and wellbeing space, the reception and the rooms for visitors are on the groundfloor, and the two bedrooms with bathrooms are on the first floor. A lift Is the link with a staircase between the 3 floors. The task and challenge was to develop with the interior designer the details of construction for the high quality standard material and finishes that was expected for this project. The aim was to keep the spirit of the design and to hide the technicicity behind the fine quality of the details. The complexity of such project lies in the fact that you have to understand the vision of the interior designer in order to produce the construction plans, details schedules, tendering and do the site supervision until the handover following the philosophy of the ‘décor’ and the spacial lay-out. Keeping this in mind, LPA Architectes was able to successfully collaborate with some well know french interior designers: B. Moinard, J. Garcia, Ch. Tassin, Marseuil.
