Hello everyone,

My wife and I are currently favoring the attached design for our house project. It is our own concept, inspired by forum discussions, catalogs, and model homes, but also discussed with architects and now unrecognizable compared to the first drafts.

A first detailed drawing is in progress (which may include structural and building services adjustments), so general criticism is welcome, but especially suggestions on potential problem areas or ways to achieve essential improvements through small changes: After all, we don’t want to build an expensive house only to regret it later, but rather invest in meaningful improvements (e.g., bay windows). At the bottom, I have listed some specific concerns.

Framework conditions:
  • Planned residents: two adults (working days home/office: 2/3 and 3/2), two (initially small) children, two cats, guests staying several weeks per year.
  • Conditions: Small-town new development area in Mecklenburg-Vorpommern, site coverage ratio 0.35, maximum one full story, eaves height max. 5m (16 ft 5 in), gable or half-hipped roof with 20°–50° pitch, minimum distance to street 5m (16 ft 5 in), to neighbors 3m (10 ft).
  • Plot: 938 m² (10,094 sq ft), essentially flat, with utility garden and play lawn.
  • Neighboring plots: Northeast (“right”) already developed (close to road and at distance from us, since their garage is on the side facing away from us), southwest (“left”) not yet sold.

Site plan with building footprint, boundary lines and dimensions


Design:
  • Footprint: approx. 15.5m×11m (51 ft × 36 ft) + garage overhang 2m×8m (6 ft 7 in × 26 ft), garage-boundary distance 1m (3 ft 3 in)
  • Living and utility space: ground floor approx. 115 m² (1,238 sq ft), upper floor approx. 125 m² (1,345 sq ft), garage approx. 40 m² (430 sq ft)
  • Ceiling height: ground floor approx. 2.60m (8 ft 6 in), upper floor approx. 2.50m (8 ft 2 in)
  • Building services: ventilation system, photovoltaic panels on southeast roof, underfloor heating powered by air-source heat pump everywhere except garage/attic.
  • Location: the house should be as close to the street as possible (see plan) with the main entrance facing it (southeast), to maximize garden space.
  • Gable roof: rather flat (25°) to allow for a high knee wall (>1.20m (3 ft 11 in)), attic therefore only used for storage.
  • We are foregoing a basement in favor of a larger footprint, which also enables a barrier-free guest area.
  • Ground floor: the living area should get both sunlight and garden views, so it must be on the west side.
  • Upper floor: usability of space is the priority, so we accept the narrow corridor (approx. 1.5m×8m (4 ft 11 in × 26 ft)). Still, generous dormers, including in the stairwell, should provide enough daylight.
  • Exterior walls are brick-clad, interior rather modern: white walls/kitchen fronts, tiled floors on the ground floor, PVC on the upper floor.

Notes on the floor plans:
  • Area measurements do not account for sloping ceilings on the upper floor.
  • ⚡ means high-voltage electricity, W (waste) water

2D floor plan of a house with open kitchen, living room, bedroom, bathroom and garage

Detailed 2D floor plan of a family house with bedrooms, bathroom and corridor.


Development:

We had several designs, including with a basement, without construction over the garage (which was recently confirmed as possible), with open space, guest rooms on different sides, a 180° half-landing staircase, etc. – the current approach now seems quite logical to us and despite the naturally high costs, not extravagant. I grew up in a house with a full basement and converted attic, and the plan tries to provide similar spaces over two floors.
  • What we like: the bright living room, purely functional generous sizing everywhere, especially for guests and thanks to the large room upstairs, the access from the garage.
  • What we don’t like: see also the “Concerns” listed at the bottom. Otherwise, the “very generous” house (architect’s comment) might have few ‘eye-catchers’ for its price, e.g., no gallery or two bathrooms upstairs instead of one large. Therefore, general suggestions are welcome on how to enhance the design beyond the floor plan, for instance through lighting, mirrors, windows, external design.

Ground floor details:
  • Living room with window fronts each with a door leading to terraces in the southwest (for sunlight) and northwest (toward the garden).
  • Kitchen open to the living area; appliances located in a central niche—therefore, to minimize noise, the oven/microwave are there instead of the refrigerator.
  • Room behind kitchen (separated by a slightly hidden door) serves as storage and a place for some kitchen appliances and an additional worktop.
  • From the hallway, a doorless passage to the living room, doors to guest room, guest toilet, and utility room, also from there access to the garage.
  • Large guest room with barrier-free bathroom and external access, potentially a one-room separate apartment.
  • Garage for one car, e-scooter/bicycles and as a workshop/storage room, for example for garden tools.

Upper floor details:
  • Children’s rooms on the sunnier gable side.
  • Children’s bathroom with bathtub, master bathroom with washing machine/dryer (but space in utility room to allow for changes).
  • Long dormers above bathrooms/stairwell and fitness/hobby room; no other roof windows.
  • Access to attic via fitness/hobby room.

Concerns / Questions
  • The (currently half-landing) staircase may need to be spiral to allow doors to fit under its end. Is preserving the half-landing for climbing safety worth a bay window?
  • Prefabricated houses often have bay windows, although they might be energetically disadvantageous. Are they mainly for aesthetics, or have we missed practical opportunities by not including any?
  • Is the staircase too close to the entrance, e.g., regarding dirt distribution?
  • We would like remote/central control for roller shutters on all burglary-relevant windows. Would narrow windows be acceptable in the utility room, guest bathroom, and ground floor toilet, to prevent break-ins? Does anyone have experience with this?
  • With a 25° pitch and 1.20m (3 ft 11 in) knee wall, is an overhanging roof suitable as a cover for the entrance and/or terrace without causing too much shading? What other canopy options would make sense, especially since the terrace is on the exposure-prone side?
  • To prevent bicycles from scratching the car in the garage, should it be widened? This would reduce the remaining strip on the southwest side, where the tightest boundary distance (at the west corner, “top left”) is currently about 5m (16 ft 5 in).
  • Is a TV placed directly next to the window front a problem due to the northwest orientation?
  • Should the pantry behind the kitchen have a second sink?
  • Would it be better to fill the garden-facing dormer entirely with windows rather than leaving corners open as planned?
  • Which windows should be included in the bathroom dormer considering there are houses on the opposite side of the street?

We look forward to your comments!

Take a look at my house building schedule on "Bauen jetzt," and you’ll have a guideline. At the start of design phase 2, you only show the architect your list of requirements—NOT a preliminary design attempt yet.

This is exactly the plan and approach I was referring to.

Sometimes you first need prior experience to prepare the ground for good advice. If this forum and threads like this have achieved one thing for me, it is the realization that I will do it exactly like this in my next build.

With all due respect... if someone has an hour to post something here on a Sunday, which is the weekend, you can’t expect it to be flagged as "Attention" by Thursday just because they responded sparsely so far.

For someone without children or older, whose kids have moved out, this might be hard to understand, but many people have a lot to juggle during the week. Besides, it’s the pre-Christmas season right now. People with younger children know what that means—baking cookies here, school plays there, Christmas concerts, dance club performances, and so on.

But those are two completely different things (?)

First, to plan conceptually in multiple stages before proceeding with drawings, and to approach the architect not with drawings but only with requirements and wishes (also known as "leading with goals"), and only to compare the professional preliminary design with your own sketches after it has been created, instead of "implanting" it with your own ideas—these are recommendations I have already given in many threads,

which, however, do not appear in the House Construction Roadmap:
that roadmap is about the phase model of the HOAI and my advice to use it as a guideline regardless of who is doing the planning and whether the payment is made according to the fee schedule. And—very importantly—the seemingly passive phase of dough resting is an independent module phase of the roadmap (my roadmap, since this "pause" logically does not appear in the HOAI).
The post titled "The Upper Floor Takes Priority" is just one of the digressions on this topic.

Yes, I just combined it for now. My next construction project is still a while away. Until then, I will read it through again, I promise.

Reading my notes here along with the schedule is, of course, always a good combination.
By the way, my schedule always appreciates when you use the comment section for feedback,
after all, it is supposed to be an "interactively" learning schedule that continues to improve.

If you apply both when building the "second house for a friend," you could start by just entering "happy wife" into your GPS for the first house ;-)

Especially considering the planning will probably take months anyway...
