??? how do you access the bedrooms? no hallway?

Can you label these rooms? Can't translate what you have on the sencond pic with the first. Room 1,2 3 etc doesn't work - how about kitchen, living room bedroom 1 etc. ?

Do your floorplan to scale. Graph paper works at this stage. Walls can be 4" wide. Yours are not. 6" or more for exteriors.

1.room entrance,2.dining room,3.bedroom,4.bedroom,5living room,6kitchen,7.bathroom

the walls should be 15 inch

Did you grow up playing Pacman?

radoslav, is this a project for a home you want to build and live in? A project for a college or university course?

dani explained to you that interior walls are usually four inches deep, and exterior walls are usually six inches deep. When you say "the walls should be 15 inch" that doesn't make sense, given the context.

You need to label your floor plan with all the measurements, and each room should be labeled with its purpose. The floor plan should be drawn to scale, with all doors and windows clearly marked, and also to scale.

You say that, in your opinion, your floor plan is not very good. That's okay, we all have to start somewhere. But if you want it to be better, then follow the guidance you have already been given here. That is how you will improve.

Please use graph paper. The program you used to make your first image should be saved for much later in your process.

Good luck!

"Design project" as in school project? Imaginary house? House on aquired site?

I suggest you use quad paper to do your plans to scale ( 1 square = 1 ft). The floor plan you show looks like a maze. When you draw you rooms imagine yourself walking through to get from one room to another and ask yourself if that makes sense. Open plans are now very popular, something for you to consider. Here's an example of a small open plan 2-bedroom house plan. You can also go on internet and look at house floor plans to get some inspirations.

This is a finished house purchased by me.It's just how it's built

I DON'T KNOW HOW TO REDISTRIBUTE THE SPACE.I am starting the renovation now.

For a start, you can’t remove any load bearing walls (the ones that support the roof trusses). That said, having to go through one bedroom to get to another is going to be a major pain in the backside. What possessed you to purchase this house?

BECAUSE THE PRICE WAS VERY GOOD

The price was good for a reason!!. It is not livable. Get a structural engineer and an architect in whatever country this (mess) was built, They will probably tell you to tear it down and begin anew, as the cost of making this livable will EXCEED the cost of tear down and new.

Hold the demo, or rue the result, and as posted above, nobody here can help you: )

It's not that bad, and it's certainly livable......It's an unusual and inefficient design, but still you can make a home there without tearing anything out. If you are going to renovate, you have to renovate big, and you'll need better plans if you're going to do that.

The key information to know when creating or evaluating a house design is the site and the owner's needs; neither is shared.

It would be best if you contacted a design professional in Australia.

Of course it's livable. Good heavens, Jan, have you never seen a railroad flat or shotgun house? radoslav's house has plenty going for it, It's just that the flow-through seems a bit awkward. radoslav, the reason some of us have been asking for a detailed floor plan is that the image you first posted makes it very hard for us to see the doorways, and you didn't clarify what kind of help you were looking for. You just called it a project, and asked what we thought. People need context in order to advise you usefully.

Your profile says you live in Australia. You've posted on the North America site. Try https://www.houzz.com.au to get more on-point help with materials, suppliers, local pros, and from other people who may be more aware of housing trends and what's available where you live.

Did you get a floor plan when you were looking at the home? Even sharing tust or actual pictures of the home would be helpful. It is so exciting buying a home and wanting to make changes. Many here will say live in it for six months to a year first. We had no interest in that and gutted it within six weeks of owning but we had a clear plan of exactly what we wanted. You need to figure out your wants, needs, budget and what is reality. We needed structural help as we moved a load bearing wall but we worked with an engineer and it was still doable

I am about to replace the roof and the pavement in the yard will be made of granite

but I haven't started inside yet .

lisedv sketch is very accurate.

Lisedv's suggested new layout is a good one given the constrictions of the current layout, but you would probably need to have installed special steel joists to support the roof where she has moved or eliminated the crosswise walls, which I suspect are your load bearing walls.

This would be easier to do while you're replacing the roof, before you put the new roof on.

Do consult a building engineer before you start anything as it will save money in the long run.

I second or third or whatever it might be to have a structural engineer inspect your home to tell you which walls are load bearing before doing any demolition or construction.
