Here's what I've found after living in and visiting many tract homes- LR-13x18 FR-12x16 (and that they not be in the middle of the traffic flow pattern aka many tract homes post ww2 till about the late 50's) Kitchen (no eating area) 9x11 DR/Nook or other eating area 10x10 Entry-at least 3'6" wide 4' better Bedrooms (good design would at least provide 2 good bed walls aka no doors or windows in it) MBR-12x13 w/ at least 10 linear feet of closets All other bedrooms-10x10 with at least 5 linear ft of closets all closets 2' deep, Baths-5x8 but 5x9 better if fixtures lined up on one wall and tub/shower at end 7x8 and 8x8 with the tub/shower fully accessible if it's 5 ft long 6x8 if it's a 3' shower (fixtures lined up on 2 opposite walls). If you look and many floor plans the best ones will have all of this. Note that square footage does not have to be a lot-ciculation/flow between rooms helps this.

It might be possible for you to make your bedroom taller by building into the roof void- measure how much space you have- you may be able to fit two floors in.

This is for my home office. I have a small room 10ft * 8ft with beige color on the walls.Shiny rustic beige and siler lined curtains and brushed nicole curtain rod.Wall 1 : The room has 1 side with a corner entrance white wooden door. On the same wall other corner has a built in closet with white doors.Wall2 : In front of the closet, the wall has a window. Next to windiw I have kept a black 8 cube organizer vertically with books.Wall 3 : corner towards the window I have placed Ikea black Hemnes desk , which is my work station.Wall 4 : ? This wall is in front of the desk.How should I decorate this room ?

A clever solution to hiding closet/ hot press beside fireplace in a restored centuries old cottage.
