Is it possible to make a blue print type document for the free company large house?

As we know we can add walls to make rooms etc to expand the interior of the house. It would be fantabulous if we could plan out where we wanted to place walls or rooms! Think of the possibites!

Would the community be interested in this? Does anyone have the know how? Would this be best if SE implemented a function that let is map it out somehow so we could view it?
