Hello! i'm Evelyn and i'm an Architect, and an interior designer, and i believe that the best way to make architecture is to have a concept, that makes it the heart of the project, and in every design aswell. And i think that is what you are looking for, so you can make this room into a special place where you can enjoy and share your music with your family, and be able to practice all together. I could make a plan in autocad with the measurements of the room and the size of the instruments that will be there, and then make a concept (that we will debate together) so i can show you examples of the ideas i will give you and where and how to place them (painting, decoration, placements of things, and whatever we need for the project).
Please be welcome to contact me to discuss further details,
Best Regards
Arq. Evelyn Amaya
