Dear forum members,

We bought a plot of land last autumn and are currently deep into the floor plan design. We would like to share our current draft with you and welcome any comments and opinions.

[F]irst some preliminary information about the plot and its buildability:[/F]
  • 1000 m² (10,764 sq ft) rear plot, southwest facing (so southwest is on the left side of the site plan)
  • Building boundary up to approx. 16 m (52 ft) behind the property line (up to the dashed line on the site plan)
  • No zoning plan (construction according to § 34 of the Building Code)
  • Groundwater at surface level and peaty soil (exact geotechnical report pending), so piled foundation required and no basement
Our requirements were and still are:
  • Affordable! (Our maximum budget for the house including foundation slab is €230,000)
  • Country house style
  • Bright, large windows facing south/garden
  • Open living/dining/kitchen area
  • Family of four, 1 bedroom and 2 children’s rooms
  • Not oversized, max 150 m² (1,615 sq ft), preferably less
House design:
  • Solid construction using Ytong blocks (for us the most cost-effective option, although we would have liked to build with wood as well).
  • Developed ourselves after studying various floor plans (including from the book "Affordable Building with a Small Budget" by Achim Linhardt) with support from architect friends and our planner (an independent civil engineer).
  • Dimensions 12.50 x 7.50 m (41 x 25 ft) (the measurements shown on the site plan are from an earlier draft).
  • What we like: open living area, all main rooms have large windows facing the garden, efficient size, although the children’s and bedroom could be smaller, sewing/work nook behind the stairs upstairs, plenty of wall space for large wardrobes in the upstairs bedroom and hallway on the ground floor, light shaft in the stairwell, staircase (we originally wanted a straight run staircase but it would have taken too much space; the one with three quarter turns is also fine with us).
  • What we don’t like 100% yet: the height of the house from the outside. It is currently planned as a two-story house with an eaves height of 6.2 m (20 ft), with the ground floor 2.84 m (9 ft 4 in) high and the upper floor 2.60 m (8 ft 6 in) high. The gable roof will be an uninsulated, unfinished cold roof, mainly because of the economical prefabricated truss construction method. This is a bit disappointing because I really like sloped ceilings and did not want the character of a townhouse. Lowering the roof with a knee wall of about 1.90 m (6 ft 3 in) and an insulated roof with open sloped ceilings would probably be more expensive due to the rafter/beam construction. We would also lose the garden view through the floor-to-ceiling bedroom windows.
Now for our questions:
  • Simple: What do you think about the floor plan?
  • Can you still imagine the relatively tall two-story house having a country house character? Maybe it depends on the facade design and choice of materials? Do you think it looks too “blocky,” especially from the front entrance side? Or would a lower eaves height with an attic conversion including a knee wall be preferable?
  • We are still unsure how to arrange the windows on the garden side. The drawing with the elevations shows two possible versions. We actually prefer it when the upper floor window is centered over the lower window front. However, this does not align the interior line of sight from the entrance door to the garden/patio door (see ground floor plan). This represents version two; for version one, the window front would have to be shifted about one window width to the right, so that the patio door is behind the dining table. With the window front shifted left, the interior looks better to us, but from the outside it looks strange if it is offset from the upper floor window, right? What do you think?
That’s it for now regarding our project. We really look forward to all your opinions!

Best regards

Do you mean 113.5cm (45 inches) for "110"?

OF COURSE north is at the top of the plan. I don’t think it’s fair of you to pick a fight here with @kaho674 or others just because they’re thinking for you, since you didn’t orient the plan or include a north arrow.

I didn’t mean to pick a fight, and honestly, I don’t find the little jab unfair, especially since @kaho674 has also made some pointed comments. You know, if you dish it out, you have to take it. Basically, I’m very grateful for all your comments and your patience – you could just stop writing at any time, but you’re still engaging. I really appreciate that!

True, I didn’t add the north arrow, but as far as I know, I mentioned in one of the first posts that the garden side (which the living/dining area faces) is southwest. I also thought it was on the site plan, but I think I cropped out the compass rose there. However, when the orientation discussion heated up, I explained several times how exactly the house is oriented. Really, multiple times.

And actually, the orientation is not our main focus; we’ve put a lot of thought into it and are confident about it. Of course, that doesn’t mean you can’t still make suggestions.

Maybe you missed that I was the one who uploaded your site plan including the north-south designation? I have to admit, I only estimated the positioning from your description in #1. But there is definitely more south than west, so you’re right, the living room probably gets enough sun.

But that does not change the main point: you have placed the storage and utility rooms where the sun shines and some of the living space in the dark north. This can be clearly seen from your sun path graphic. I colored the house sides differently to maybe help you see what I mean:


Red means sun, blue means shade. And yes, of course, a few rays of sunset reach the living room as well. The graphic is just to illustrate which rooms are bright and which are dark.
I would support your plan immediately if there were compelling reasons to have the utility rooms there, but I don’t see any. Maybe late info will come up about a short connection to the street or something like that, but so far we readers are in the dark.

You didn’t understand something at all. I’m not rotating the house; I’m mirroring it. So the utility room ends up in the blue corner. But I would still change some of the rooms a bit.

No, it’s 5 to 6m (16 to 20 feet), and it won’t work—especially in winter, since that window is also higher and narrower than the others.

But what am I saying. Let’s just wait for the offers. Then the house will probably shrink to some standard mini floor plan or it turns into a duplex and all of this fuss was for nothing.

Thanks, @kaho674, that’s a very detailed (and mostly tactful) explanation. I see what you mean. But it’s not just about where the sun shines directly, it’s about when we use the rooms while the sun is shining there. We’re rarely awake at sunrise, but almost always at sunset—that was our thinking. Someone else suggested rotating the house—that’s correct. Sorry for the confusion. Mirroring the house might be possible, but would have to be done entirely. Just swapping kitchen and office (I think suggested by @ypg) would be inconvenient, as then the kitchen and utility room would be far apart. Also, a possible future extension might make it tricky if the entrance moved to northwest. The driveway is on the northeast side (so the path to the utility room is actually shorter wiring-wise). The TV wall without windows would then face east. I’m not really convinced by that.

I observe:
The layout of the ground floor fits very well with the cardinal directions and doesn’t need to be changed. Kitchen in the southeast, living room in south and southwest to northwest. Fits well.
The ground floor can stay open if desired, though I would reconsider the staircase. Maybe a partially separated staircase from the living room would be more practical, even if it has less style.
The upper floor fits quite well. I would improve the bedroom by placing the ironing room in the northeast and the bedroom in the southeast.
I would put a wall or something on the gallery to make it a storage room.
Now we have to wait and see how the prices come out.
Savings potential could be: instead of Ytong, Hansapor. Instead of full-height windows, normal-sized windows. All windows a common builder’s merchant size with rough opening 102.

You could mirror the upper floor, of course. I would even find that practical for waking up in the bedroom. However, the bathrooms would then not be stacked (which saves money with short piping), and morning sun in the bathroom is nice, too. So, that’s how we have it so far.

I just reluctantly replaced the staircase with a spiral one, which really saves space… even though I find it much less attractive. Do you think it’s better? Yes, we still have to wait for the offers, which will take time. Before that (once we finally finalize the floor plan), I have to plan the windows on the facades. So far, especially the northeast facade with the entrance door looked pretty awful.

Floor plan: Kitchen on the left, dining area in the middle, living room on the right, staircase at the bottom.

That’s not a problem.

Uh, no.
Try to detach yourself just a little bit from your daily routine. That can change drastically over the years, and please don’t start with the idea that you’re different from everyone else here. The older members here used to sleep until 10 a.m., but now they’re up at 7 a.m.
Besides, that’s actually not the main point. The goal is to design an open, bright living space. If you stand in the middle of that room (where the dining table is now), according to my plan you will have sunlight ALL DAY because the openness of the rooms is aligned with the sun’s path. From east to west, the room is open, and with proper window planning there is always natural light. It wouldn’t matter who is awake when (there are other family members, too).

Upstairs you could mirror the layout, which might actually be practical for the bedroom to catch the morning light. However, then the bathrooms wouldn’t be stacked (which is supposed to save money on piping), and morning sun in the bathroom is nice as well. That’s why we have it as it is so far.

Those are the kinds of thoughts you have when you’re stuck on a floor plan and now trying to force it into a new concept. That’s not how it works. The old plan gets scrapped and you start from scratch. That’s the way it goes.

By the way, plumbing to the utility room also costs a significant amount. Roughly speaking, people say about 1000 per meter (that’s very variable though) – but you have gas, right? Try drawing the existing utility connections on the street into your plan.

Bathrooms stacked on top of each other: do not change.
Swap the bedroom and dressing room so the bedroom is no longer directly adjacent to the children’s room.
Where the indoor palm tree is drawn upstairs, add a small wall with a storage closet behind it for miscellaneous items.
Front window: urgent need for action, it looks terrible.
The window in the storage closet can be removed. Another 500 to 1000 saved there.
Pay attention to the window size of 113.5cm (45 inches). We used this size consistently. All blinds and roller shades fitted perfectly from Ikea or Danish Bed Store. You will save over 1000 euros later if you keep this in mind now.
Downstairs: don’t be overwhelmed. The utility room with the gas boiler is large enough for a washing machine, dryer, and a Billy-style cabinet with doors for cleaning supplies, etc. Our utility room is even one square meter (about 10.8 square feet) larger but has an exterior door, which I recommend you plan for as well. It provides a separate entrance for dirty items.
Also include a utility sink with a cold water tap in the utility room inside the house. How often do I quickly need water! Bucket under, tap on, done. Karsten

Karsten, with two of you working on four, there is more to do, and then 1 square meter at this size is not a small amount. However, the original poster is not unskilled at DIY. So, some clever solutions may still come later.
