The office project is just phase 1 of a 4 phase project to remodel the basement. The office was the cheapest and easiest part to do first. It also helped us get more organized and forced us to clean out the basement of all our junk.
The grand scheme is to put a 1/2 bath in the basement and divide it into an extra living space and storage/laundry area.
Now that the office is done our next project is build the dividing wall between the living space and the storage and laundry area with a 36" pocket door in it. This is a little tricky because we are also going to replace our water heater with a tankless water heater that will hang on the inside of the wall. This has to be done all at the same time. Shut off the water, remove the water heater, build the wall, install an outlet for the tankless, install the tankless. It will take the framing guys and a plumber working at the same time almost. Once this is done we'll build some more storage shelves on the inside of this wall and move all our storage to that side.
The 3rd phase will be to install the 1/2 bath. We want to use a standard toilet which means cutting into the concrete and connecting to the exisiting cast iron sewer stack (our quote for this is pretty expensive so we'll do it next year) . Then we have to frame the bathroom and plumb the water for the toilet and sink. Then do the drywall and finish work. The bathroom will have a standard door.
The 4th phase will be to finish the main living space by framing the outside, doing the electrical including lighting, insulating and then drywall the entire room including the ceiling. Then we paint and trim the room and decide on flooring options.
I used this software to do an initial drawing of the what we wanted to do.
