We also built in the affordable Lower Saxony area: signed a contract 7 years ago for 185,000... I never added it all up, what else the trades added during construction, but there was quite a bit more. Frankly speaking. And YES: we are all talking here about the pure house price. We are not talking about earthworks, paving work, the splash protection around the house or the entrance platform, nor drainage or rainwater connection to the sewer... with tiles we were then probably at 230,000/240,000... you have a tiler anyway...
You can post the construction services description here. There are some who will have a look at it.
Don’t let anyone convince you that some things are not doable. However, I haven’t read from anyone here who exaggerated. The costs may surprise you. The word "ready to move in" is just as little an official term as turnkey, so watch out!
I don’t even think , our penny pincher, managed with his small kitchen for 6,000...
If you put it that way
A big item would be enough sockets, for example. If your builder thinks that "ready to move in" means 2 sockets in the kitchen are enough, then you need to upgrade. That costs money. What about internet? LAN? And don’t come to me with Wi-Fi
A second sink for four people? A cabinet in the bathroom? A mirror? I cannot imagine you saying "you only build once," but small stuff and DIY store goods also cost money.
But it just keeps growing!
You are young and don’t have much yet.
It all increases: clothes, kids stuff, cleaning stuff, junk. Before throwing things away, you hoard. We are two and our 14 sqm office houses a large cabinet with a workspace and folders and such stuff, the other side winter jackets and craft stuff as well as gift wrapping paper, card games, holiday plans and collections.
When we moved in just one computer workspace, now there have to be two. So there’s also a desk in there now. By the way, we don’t have a printer. And the books are also on shelves above the door*. One piece of sports equipment had to give way for lack of space. Now my husband wants to do spinning, of course at home. We live in the change of our own time. What is the current state now will not be the current state in the house. I’m not talking about a drum set. Let it be the sewing machine, later then the tumble dryer, the bigger freezer or actually a kitchen machine that takes up space.
Your utility room is primarily for the technology. For gas you need a hot water storage tank. Ok, you don’t have controlled residential ventilation, but then:
Broom, mop with bucket, vacuum cleaner, handheld vacuum, window cleaner, dryer for wool/sports/hand wash, dirty laundry container (some have three!), space for ironing board and basket with clean laundry, washing machine, dryer (that can be stacked), cleaning supplies, electrical appliances for the kitchen (fondue set, roaster, deep fryer, baking pans, clay pot, champagne cooler), canning jars, freezer or beverage cooler, shoe cleaning supplies, yellow bag for recycling, beverage bottles (case of water, beer, and juice), a few supplies like onions and potatoes, bags and sacks for shopping or gift wrapping, decorative stuff (2 boxes Christmas decorations, 1 box Easter, 1 box general), gift wrap, office folders, writing stuff, office supplies, red light lamp, medicines, photography equipment, hobby stuff (badminton, fishing rod and such stuff must stay outside), manual tools, drill, cordless drill, a few paint buckets, white paint, brush and roller, electrical stuff, light bulbs, batteries, vases, spare cutlery, picnic basket, small step ladder, 2-3 flower pots and plant fertilizer, empty bottles, dog food, cat litter box, 15 liters emergency water, sewing machine, fabric scraps, water sprayer for plants, suitcase, travel and sports bag, carpet and tile scraps, etc.
You can probably cross off 2-3, but very likely I forgot some as well.
*By the way, the bookshelves under the ceiling are now gone because they weighed someone down.
The idea to equip the walk-in closet with a space for the washing machine is great, but that must also be specially planned again because of the moisture. So if you pick that up, additional costs will already arise for you. If you want to wash in the utility room, then consider that washed laundry could also be lying down there in your mudroom. One could also apply the saying here: don’t poop where you eat! Not even animals do it.
You are currently planning the utility room as an all-in-one miracle worker, but it isn’t one. 9 sqm is not much. Also, your kitchen area is not nearly fully optimized. You roughly have about 6.80 meters of running space in the kitchen. That is more than the 3.20 standard from a 3-room apartment. But we all know that storage space or kitchens should have a lot of storage space so there is room for batteries or the Tupperware collection as well. Properly planned and set up, it could get twice the storage space, but not for 6,000€.
Some of your doors actually take up space, four doors in the kitchen, two in the utility room... I won’t criticize the second one in the utility room now, but you have to plan accordingly. What the utility room doesn’t have has to go somewhere else. A bit of plan B has never hurt anyone.
Think about whether the sofa in front of the TV will have room or if you can still go through the terrace door. This has been mentioned several times but not responded to.
Also here: the sqm of the children’s rooms are probably only the floor surface?! Accordingly, the children’s rooms are sufficient in size but not the world. I would rather use the space in the upper floor for the children than for yourselves and then the kids in the living room... But whatever: you can always rearrange.
We always use the stairs or the office for that.
I would also make the storage under the stairs for the current jackets, bags, and shoes. Shelves below, a rod above. Boxes further back to pull out. That also fits well under the sloping roof.
About the floor plan
It’s not mine. I would probably remove/straighten these middle walls on the ground floor and separate the hallway right behind the stairs with a straight wall. The door for the storage under the stairs from the front, that is the long side. Nice double doors to the dining area.
Sliding door to the kitchen all the way to the right of the plan and the utility room door 65 cm from the wall. Then in the kitchen, a nice 2-meter-long wall for tall cabinets arises, and behind the utility room door there is storage space for a proper cabinet, too.
I would give the utility room one more window, and remove one in the office instead. Also for placement space. The kitchen can also take more light.
Plan a terrace door by the dining area. Then a sofa also has space there.
The shower upstairs is too short for "without shower door." The toilet could be a bit narrower... I would classically put the tub next to the toilet and the sink at the window. Then there is also room for a longer shower, and the tub can serve well as a shelf and seating area where you need it, namely in the middle of the bathroom.
3.30 m is just about okay as a width in the bedroom.
Thanks for the detailed feedback! We will go through your remarks calmly.
What comes to mind quickly: the terrace windows have already been replaced, so doors and floor-to-ceiling windows.
And the shower really is too short? It was drawn like that by the architect, we will inquire about that again.
