ᐅ Floor Plan Optimization (Extension, Additional Storey)

Hello dear community!

I am new here, so please forgive me if I haven't included all the information right away. I can provide additional details if needed.

We are currently working on finishing the upper floor and also expanding it slightly. There will be a separate entrance, meaning the parents will live downstairs and we with our family upstairs.

I have roughly followed the guidelines. I hope the information provided is sufficient, but as mentioned, I can add more if necessary.

The basement already exists.

What is the most important/basic question about the floor plan summarized in 130 characters?

I am basically satisfied with the initial plan. I would like to get some tips from you. I have summarized some important points here:

• I would like the kitchen and living room to be separated by a fireplace and not have direct access from the cloakroom to the living room. I want the living room to be a retreat room, not a passageway. But I’m not sure how much can be done since the chimney connection is already available. We could extend the angled wall further to gain more space.
• Do you see an issue if you always have to walk through the living areas to get to the children’s rooms? Considering teenage years?
• The terrace shown in the plan is much too small. It needs to be at least 30sqm (323 sq ft). Southeast or southwest orientation?
• The dressing room will be separate from the bedroom since we both work shifts and don’t want to disturb each other when getting dressed.

Upper floor
Gray walls are existing
East and south sides face municipal streets

I’m aware that the options are relatively limited due to the existing structure. Nevertheless, I look forward to your suggestions and tips.

Best regards
