@Cintia Chicon An architect might have some home plans that they can sell to you, or they can design a custom house.

Dealing with the architect, hiring the general contractor, budgeting, etc.

I spent all day doing this, and when i showed my parents, they were shocked.Years later, I graduated high school and decided to I wanted to be an architect.

also I presume I will need an architect?

We don’t sell ADUs but we do refer homeowners to architects and GCs with experience in ADUs.

Essentially the architect didn't properly detail the separations and this was compounded by a poorly located return vent and shoddy insulation in the wall to wall area.

Do I need an architect or simply hire a GC who can do the work?

Architects and designers work together all the time.

Permits need plans so you need to include the architect cost which is about 10% to 15% of the cost of the project.
