#1 is the only one that works with your doorways. But I would rethink the sectional pieces which look too large. You will need at least a floor lamp. Your table/chairs looks narrow in relation to your sectional - is it to scale in the drawing? You may not have enough room. I would use a sofa against the wall and two chairs on either end facing toward each other.

You can also think on panel work with some openable shutters which can hide the boards as well give an access to use when needed . Bottom can be a sleek storage with louvers where inverter can get tucked in and also a seat or a ledge used for multipurpose. One thing to remember this set out would not be budgeted but, can allow you to explore option to make it look good or articulate well.

The simplest thing will be that the faculties should be practioning architects as well as professors. There is a wide gap between the bookish curriculum and the one which is going outside in the field. The study should be grounded to the regional feasibility and how things are actually practised when you get into the field. There were great structures built but one should also study the whole process of design approval in each design, like what was the need, who were the clients and what they demanded, how did the architect come to build the said thing. The one miss in education I find is that the architects face difficulty running a business and that too should be a part of the architecture degree curriculum.
