Floor plan design for 212 sqm bungalow - improvement suggestions

Hello everyone!

Attached is a self-created floor plan. There is no plot yet. Probably a large plot in a green area, house facing north. All points mentioned above are fixed; it is only about positioning. Similar sizes and the same number of rooms should be maintained approximately. The rooms were positioned so that the bedrooms face open to the east and south (sunrise), living room and dining room south/west (sunset on the terrace). Utility room and bathrooms to the east as light is not necessarily needed. Windows and roof orientation to the north are somewhat closed. (Open the house to the south for warmth) The bathrooms receive only skylights. (Advantageous for privacy and walls easier to maintain since water cannot reach the window). The bathrooms, kitchen, and utility room were deliberately positioned close to each other to save costs regarding shorter piping routes. The house should promote communication and togetherness in the family. Through the sliding door there is also the possibility, for example, to receive visitors and isolate the bedrooms visually and acoustically to ensure peace and privacy for children. Almost all rooms are open to the ceiling. Unimportant rooms such as the hallway have a ceiling and offer the adjoining rooms a second platform (for now, however, not important and/or decisive). Traffic areas should be kept as small as possible. Efficiency/cost reduction is often a very high priority. The living room should be sunk about 50 cm and reachable via a surrounding staircase. This makes the area cozier and is a visual highlight. It is important that in the left area, whether kitchen, dining area, or living room, communication and togetherness are promoted, hence the open structure. The fireplace and the niche directly next to the front door slightly delimit the living room, which contributes to coziness. In the niche (and in the fireplace) there will be cabinets for jackets and shoes. Both the niche and the fireplace do not extend to the ceiling, which offers a great sense of space both in the living room and the entrance area. If storage space is not sufficient, it will be retrofitted outside through (insulated) rooms in the carport. I am not a fan of unnecessary frills for cost reasons if they do not contribute to comfort or well-being, which is of highest priority. The floor should consist of easy-to-maintain exposed concrete in traffic areas, utility room, bathrooms, and living-dining area; otherwise parquet or other wooden flooring. Orientation is for both family and friends (also large numbers). In the living area on the left, fixed glazing should be used everywhere except for a sliding door to the left of the dining table. Bedrooms should have only one openable window. A central ventilation system should be installed in the house. Heating is via underfloor heating, presumably with a heat pump. Photovoltaics can be retrofitted if desired through a southern roof pitch of the carport. I have no price expectation or estimate, completely according to the mindset of working until you can afford the right thing.

Please criticize everything in detail. I am open and very much looking forward to improvement suggestions or even completely different floor plan proposals. I want the perfect floor plan for a large family and often many friends that offers maximum comfort, community, healthiness of living, and well-being factor. For meaningful changes and additions, I am gladly willing to spend significantly more money if there is added value. I am very happy and thank you sincerely in advance for every improvement and tip!

Additionally: Can someone tell me approximately what such a recess in the floor slab costs extra and what additional effort it involves and how it is processed? (E.g., possibly extra sealing)

I'll put it this way: Your (partially) open roof and the lowered floor slab multiply your cost-saving measures many times over. Your renunciation of "frills" is the real cost driver.

Ok. What additional costs are to be expected due to an open roof? I save myself a construction or even a concrete floor for the 1st floor, right? I would have the costs for processing the walls and the roof anyway. Regarding the slab, I unfortunately have no knowledge about the costs. What is the decisive point about a lowered slab? (Material, waterproofing, etc.)

Sorry, this is one of the most modest plans of recent years. There is nothing beautiful, practical, sensible, or affordable about it. And extremely difficult to finance, as banks will tear the house apart like this.

Things that catch my eye at first glance:

- No possibility to furnish the living room at all. If you ever want to put 2 DVDs in a cabinet there is hardly any space for that in the living room.
- Huge entrance area but no wardrobe.
- Besides the cost factor for the living room, the surrounding stairs are also not good for accessibility. This should be considered for the preservation of the property's value.
- The rooms, despite their size, are rather narrow and long. This makes furnishing difficult. Take for example the two at the bottom of the plan. The window runs along the entire bottom wall. Not only can you not place furniture in front of this wall – also tall cabinets on the two adjacent walls would look bad because they would then be "in front of the window". The top wall of the plan has a door and is narrow. Where do you want to place a larger wardrobe or something similar there?

I am missing measurements, but I already see problems with the span due to the roof orientation, because nothing should be full height as missing supports.

Since there is no plot of land yet, it is always difficult to design floor plans appropriately. For example, HAR .. may be somewhat unfavorably located given your assumed layout.

Rooms 1 to 4 should be roughly furnished once .. door and window positions are not closet-friendly.

And, when planning with a shed roof, I would choose the orientation so that it can be well equipped with photovoltaics.
