Aix-en-Provence Villa
The hotel needed to be taken in hand for several legal upgrades, Tatiana and Ludmilla came along and took care of EVERYTHING. We took the opportunity to trust them with the total renovation of the hotel; the work went well and the result is amazing 😉
Parisian hotel 75017
We called Tatiana and Ludmilla, from LT Design Architecture for the study and realisation of the restructuring of a house. We really appreciated their advice and responsiveness, especially when it came to preparing the building permit file. The plans, 3D photos and augmented reality visit are a real plus as they allow us to preview in advance the final result. The mother and daughter team works perfectly. We have no hesitation in recommending and using LT Design for other projects in the future.
