If I didn’t turn it into a B&B and I had plenty of money, I would have 3 of the bedrooms each have their own bathroom and nice sized closet. If the bedrooms don’t already have their own bathroom I would renovate reducing the number of total bedrooms.
Maybe also an in-law apartment combing two rooms and adding a microwave, mini fridge, and coffee maker or possibly a small kitchen with a two burner stove and sink added to the fridge and a combo microwave/oven.
Also, the master I would additionally make a small sitting area, if it didn’t already have one, and the closet would be a dressing area, in other words large. The closet would be at least 12×12 with a 3-way mirror, bench seat, maybe an island of drawers that doubles as a folding table. I wouldn’t have enough clothes to fill it, but that’s what I love about it.
I’d have:
My master.
Two guest rooms.
In-law apartment.
A cave room for my husband.
An office for me.
An exercise room with weights, treadmill, elliptical, and a ballet barre.
A crafts room with a sewing machine, shelving for regift items, wrapping paper, gift boxes, and any sort of scrap booking things.
A library with any books we have (not many actually).
Is that 9? The rest are empty. Although, there might only be 9 after the renovation.
