I find most free design tools are hard to use and maybe just post the issues you are having with the design here to get some free advice . DO NOT start another post but we would need a to scale floor plan of the basement showing windows access doors or stairs wether this is awalkout or not and all measuremtns clearly marked posted here in a comment . Then a list of what you want in the space .

Why would it need to be photorealistic?

I use paper and pencil, but it does take a long time to get it to look photorealistic.

This is a 3 floor backsplit unit and below is the basement floor. Utility and Storage area are with lowered ceilings due to above backsplit so unusable for making rooms unless basement is underpinned which I think may not be worth it since this is a 60 year old home.

I have Laundry and Recereation Room to design into 4 rooms (preferred) + kitchenette + Washroom with standing shower. If 4 rooms is too much then hoping for 3 rooms. A little living area with a table is needed too. Rooms will be rented to individual students.

D = Dryer

W = Washer

No more Windows are possible in south west of the map in Laundry room because they will open into above ground garage.

There is a drain pipe above Dryer and also one in South East corner of Storage.

The wall going through the middle of the building (North to South) seems to be structural wall.

Recreation room is built (pictures attached showing same room from different angles). This room may have to be split into two rooms.

Please reply with some designs. Thanks.

You need an architect, not a crowdsource.
