Newbie Rehabbing a 100 year old house

[Danielle Jones]

Hi every does anyone have any experience with rehabbing a 100 year old house.. The house that I am considering was built 1905 electric and plumbing is updated but floor plan is a lot of walls and fireplaces. A lot of original crown molding, solid wood doors, bone of the house in excellent condition. Is it necessary to make all rehabs a open concept.

Should I hire a designer for an opinion, or get a partner with experience.

Need help!!!!
