Inlaws have the family farm, and talked to a "builder/architect" about upgrading/renovating the old family 2 story farm house. After his out of sight estimate they are looking at leveling the house.

I am in need of help finding reliable expert advice on renovating this house as it is very important to my wife and her family history.

Her parents wanted to add central HVAC (none existing), level the house(pier & beam), re-roof and make some additions/renovations/ upgrades to the kitchen and bathrooms.

The house is structurally solid inside and out with beaded ceilings and real wood floors.

Any input would be helpful.
