Okay let's get you started......
There's 2 phases of construction
This is when you make all your structural changes. (moving doors and windows, framing walls etc.
Electrical, plumbing and HVAC get set to be buried behind the wall coverings.
Insulation, wall coverings, trim, flooring, paint, light fixtures, appliances, bath fixtures, cabinets, and more paint....any not necessarily in that order.
Draw a floor plan of what you have in mind. Very important....You need to convey your idea to others.
Do you need permits?...they'll need a copy.
Find out where the septic or city drain line goes.
Where is your water line?
Get a couple of plumbing & electrical contractors to look and what will be needed to make your studio. They'll need a copy of your plans.
They will guide you as to what you need to do for rough-in.
Having some of this basic knowledge will speed up the process as the contractors ask you questions.
You can start by cleaning the place completely out.
Remove all the stuff stuck between the stud bays and ceiling joists.
Remove the interior wall & ceiling coverings...if any.
Make a clean workplace.
Contractors will treat your project with more respect if they're not clamoring over piles of debris.
Change out any doors and windows at this time.
You can even start framing your partition walls for your bathroom.
Make your "wet walls" 2x6 to allow for fat pipes.
Don't put any of your plumbing on exterior walls.
If it has overhead doors and you're going to change them, start by shopping for your new windows and doors.
Remove the doors (carefully) and frame for windows or doors or whatever goes into the old openings.
Whew ...I'm tired...where's the beer fridge going?:laughing:
Hope this helps.:thumbsup:
