Raising the value of the house can be done in many ways. You can start re-shaping it, creating more useful space, refurbishing, changing the design, and maybe even adding some technological improvements (smarthomes).
A clean-cut way to add value inside the home is choosing valuable antiques. Special decorating objects that blend in the design, old elements from an old house that can be reused and kept for their high value, furniture from antique shops…
It will give you some headaches when it comes to the general design of the house, but with a very critical eye and some rightfully chosen antiques, your house is going to be… precious!
