I would compare both and calculate (or have calculated) as well as possible from KfW55 to Passive House. If there is BAFA funding for both (35%), I would always choose a system controlled by a central unit (a prerequisite for the funding).
Also calculate what you want anyway (e.g., photovoltaics?, controlled residential ventilation?) and then see what remains after deducting the additional funding. But it might be necessary to consult an energy advisor for that...
I consider it doable when I look at how long it took for other buildings. But keep in mind, if you possibly have to wait for the ceilings to be completed or other trades, your schedule can get mixed up. Mixing external services and in-house work in a tight schedule requires a lot of discipline.
That definitely works (with heavy machinery).
We’re doing that too, I think that fits. But flat duct is really expensive. Our 70mm round pipe costs, for example, only about €3/m ;)
I also consider that realistic. My brother-in-law did that for his son a few months ago and I was there a few times (not to help). It’s not that difficult if you have suitable plans and tools (roller, stapler...).
That is ambitious. I would plan more time here, especially so that all cables can be properly labeled immediately. Pulling cables into empty conduits takes time, laying empty conduits is cumbersome.
I see you have a plan. But better plan some time buffers here and there. Something always comes up :D
I notice my "old bones" today, and I was only on the construction site for 6-7 hours doing light work (insulation and battens). That’s different from office work; one should not underestimate the physical demands.
We will probably use both the heat pump and the controlled residential ventilation from Nibe since both can be funded together.
Combining external services and in-house work never runs smoothly, but we still try to plan it with sufficient buffer.
Thanks for the tip about the round pipe; do you roughly know how much floor height you lost compared to flat duct?
Labeling cables could really be an advantage, and I would accept the extra effort.
The affordable city villas have a tent roof, which falls under the category of hip roofs. They then have no knee wall and cannot be expanded due to the wooden structure, at most as a crawl space for storage.
What you are planning is a category more expensive: You are planning a) a beam structure that can be expanded and walked on, b) another knee wall, c) another staircase, d) a ceiling that has to bear much more than what is intended for storage space, e) insulation that turns a cold roof into a warm roof, f) a habitable finish, g) some technology like heating, h) a nice window instead of a roof hatch, i) a higher scaffolding when building, and k) material of the exterior wall. And that, although you want to build with an expensive basement anyway.
I looked a bit: 2 users who do not exactly stand out in other floor plan discussions with counter-examples and alternative approaches.
1) Both children’s rooms give up 1 sqm of living space each, and 2.60 (and not the stated 3.50) as room width is not something that cannot be improved.
2) The bathroom has the shape of a storage room.
3) Pantry is a waste of space.
These are obvious things now; there is no need to go into every detail. I could complain more, but aside from that: The planner of the general contractor draws this 1:1 for you. He will not advise you or improve “what the customer wants, he gets.”
The problem is: You see and plan this as laypeople, are fascinated by the 3D button, and no longer see the claim for a trained architect when building a house because everything is so easy. At least let the planner do it and loosen the 10 x10, which here serves only as a bad corset without this being shown.
Does the energetic support also have time on the days you have to work? The support for the theoretically targeted days must make their own living... or are the people unemployed?
I believe that. If my husband still has to work elsewhere on the weekend, he is on the third weekend on a short vacation with me :p That might sound stupid, but that’s the reality – you can’t keep someone on a construction site for more than one weekend. Not free either. With good friends and relatives, one week might work. But nobody gives up their annual vacation. Therefore, I don’t see the €45,000 equity for the shell construction.
Yes, you are right about the attic, and your arguments convinced us. So, we are moving the office from the attic to the basement, and the attic will be used for storage.
What should we do with the sqm per children’s room? We have not understood that yet.
We are also not satisfied with the bathroom; how could it be arranged differently?
My wife really wants the pantry next to the kitchen, even if it is only 1 meter wide.
And of course, we do not claim to do better than an architect; these are initially just our drafts with which we want to start. We assume that objections (possibly also due to statics) and adjustments will follow.
I have already seen this work very well in three cases in my circle of friends, each in different constellations. Every weekend and many evenings were invested with a clear goal. With a lot of help from family and friends.
That life also sometimes comes to a standstill in between is part of it, but in all cases, the respective partners went through it very well together.
I can confirm that, as I have helped out in my circle of friends multiple times. It’s all doable but leaves hardly any free time.
Yes, it can work out. But we have also often read here that it became a small disaster – with additional financing because it was about painter work including filling... I don’t remember exactly.
I was able to witness how a football team built a house with their craftsmen. But that was a few years ago... team dynamics make a lot possible.
But building extra-large, filling the missing equity with external muscle mortgage, which you rely on, I consider unreasonable. The good thing about the project is that the OP, i.e., you , can find out fairly early whether it will work. Then the helpers are still enthusiastic.
Nevertheless, one must consider that helpers must do their actual work during the day. So as a builder, you are mostly on your own. Many suppress this fact.
There are not just 2 helpers. We help each other in the circle of friends, so two men are available one weekend, and two more the weekend after. It will never run exactly as planned anyway, as last-minute changes are normal.
I’m afraid you are. If the overall project is calculated unrealistically, it is not worth discussing the floor plan. To add something: Some points (e.g., the living/dining area) I like, others (e.g., the bathroom) are rather creepy to unusable. And as soon as you start fixing things in one place, the (house of cards) collapses elsewhere. Not that 100 sqm floor area is small, especially not plus basement and attic, but the room program is rather not enough. And things like storage have not even been considered yet.
The floor plan cannot always be directly transferred to costs, so I disagree with the statement. With the presented floor plan, I can easily commission trades for €80,000, or with the same floor plan and a lot of in-house work, commission €80,000 less. For example, the choice of heating, e.g., ring trench collector for €16,000 in in-house work or a normal ground source for nearly €50,000, is already a huge difference and has nothing to do with the room layout. Likewise, KNX etc.
Pantry is too narrow. With a 15 cm shelf, it’s very expensive storage space. A cabinet more in the kitchen instead.
And the freezer?
I find the cloakroom small for 5. Especially since you have to climb over the dirty area and shoes every time to get to the toilet.
The upstairs bathroom is an absolute no-go and will be buried with the changed staircase.
If the floor plan is oriented to north, swap parents with child 3.
The freezer is already in the kitchen, next to the pantry door. The bathroom is absolutely unsatisfactory, but currently, we have no idea how to do it better. Maybe an architect has another approach here. The shoe issue with the cloakroom has also caught our attention, but where else should the shoes go? Swapping parents with child 3? That will be difficult because of a larger bed and wardrobe in the bedroom.
I don’t see that at all; I see about 120 cm... Where are garage and parking spaces supposed to go? Some dimensions would help the site plan because currently, I can't identify the 880 sqm. That would be about 20x40m, but that does not fit with the apparently drawn 10x10 or 10x13. Or does this northern triangle belong to it?
What is this information based on? A house may possibly be one-story in area I to then be two-story in area II, i.e., have a staggered floor?
First, point 1 must be correct; otherwise you already see problems in the upper floor and so do I... severe ;). Therefore, any further word about the floor plan is pointless. I would detach myself from the square meters. For the attic, consider the remarks from , and perhaps plan the basement so that it could come slightly higher at the northwest corner of the property and the home office could be moved there.
I’m attaching a site plan.
In the west, the height is 87.94 to 88.00 and in the east about 90, hence the 2-meter height difference, and yes, the triangle at the top belongs to it. Garage and parking spaces should be placed in the east, but exactly where, no idea. Either as proposed in the site plan or possibly closer to the house, what do you think?
And yes, in area I the building may be one-story to then be two-story in area II. But we were advised against that because of the basement.
It is unreasonable to expand a roof over 100 sqm floor area for roughly €50,000 when the basement floor area has not even been utilized.
As you can see here, the basement is not visible – not because it was forgotten, but because basement space is not considered important (you somehow manage with hobby, laundry, and heating).
The slope must or better can be included here. Whoever does not use the 100 sqm in the basement to get an optimal calculation for themselves, I don’t know.
I think a professional needs to come in here and inform the builders about the possibilities – also regarding the budget. This conversation here is a bit tiresome like chewing gum and apparently leads nowhere.
I keep wondering if the OP has no need to communicate or a question. He appears here and posts nothing. It’s his thread after all...
You don’t see the basement because we only planned heating, laundry, gym, and guest room there, but the arguments here have convinced us to move the office to the basement and cancel the attic expansion. I appear here and post nothing? Have I missed something? I have responded to almost all feedback so far and directly incorporate your feedback into our planning, see attic expansion. ;)
I referred to the house draft presented and therefore have not commented yet because I simply don’t see it as ready for discussion: I cannot interpret the development plan myself since it is not known to me as a source and here only parts of it are described, which seem at least strange in combination to me and partly suggest misinterpretation. The site plan lacks a legend and gives numerous puzzles, among other things, red lines look like outlines of planned buildings but (to put it kindly) do not align with the building envelope outlines. The plan excerpt is also too small – not even the access is somewhat speculative from it. I can’t work that way – and by no means is an almost perfect maturity of the draft the reason for my lack of qualified statements!
Maybe the attached site plan with concrete dimensions helps. The parking spaces and garages are not final and can still be moved.
This site plan results from a building preliminary inquiry and therefore comes with the stipulation for areas I (1 full story) and II (2 full stories).
