Hi there,
This is Bogdan from Romania.
I'm a mechanical engineer, specialized in the industrial robotics, 3D modeler and designer.
I have over 15 years work experience, designing, prototyping and launching different devices/systems across multiple industries.
I could help with your project.
In order to provide you with the best result, is necessary to determine several parameters: complexity degree of the dollhouse, materials used and manufacturing process, the type and number of accessories (singular pieces and sets), interconnection possibilities, etc.
In my opinion, the best outcome will be in the case of a modular system, with the possibility to "upgrade" the house by offering several extension modules, extras for the accessories, and different other elements which are not available in any other dollhouses (this will be a huge selling point).
And, I have the best assistant - my 9 years daughter, which have a rich imagination and craft skills :).
For any other questions, you may open a chat room here and we'll discuss about the details.
Regards
Bogdan
