ᐅ Single-family house (2 floors + finished basement + converted attic), approximately 200 sqm – modifications

Hello,
We are currently working with an architect on the design of our single-family home. Since we have three children, the house should accommodate several future scenarios. These include:
  • Enough space for everyone
  • At some point, the children will move out, and we will downsize to the living basement while renting out the rest
  • One or two children might continue living with us (multi-generational living) – possibly in the basement with a separate entrance
  • Possibly one child even starts a family in the house, and we move to the basement

Plot:
  • 710 sqm (8,000 sq ft) close to the city center
  • To the south is our rear building (two stories) attached to a 3.5-story apartment building (boundary development)
  • To the north and west are the streets (a corner plot)
  • Behind to the west is a large green plot with a single-family house
  • To the north beyond the street are apartment buildings
  • To the east there is a narrow parking lot followed by a green recreational garden area
  • We have to keep a 6 m (20 ft) setback to the streets and the usual 3 m (10 ft) to the parking lot

Since the plot already has a building, and we want to keep the rear building (it is fully shaded by the apartment building, is in reasonable condition, and might provide future expansion potential—at least suitable for workshops and storage), and since the plot is not very large, we decided on a tall house with a small footprint.

About the house
  • Eder XP9 or 10 (timber frame) in 42.5 or 49 cm (17 or 19 inches) thickness
  • Living basement (150 cm (5 ft) below ground / 100 cm (3 ft) above ground) – if affordable (this allows for the utility room in the basement and more space on the ground floor for a large open-plan living/dining/kitchen area as the main living space)
  • Knee wall either 150 cm (5 ft) or, if not much more expensive, a dormer wall above the full upper floor (both options allow the roof space to be used for two rooms; with the dormer, these rooms are very large and could even accommodate an attic instead of bunk beds)
  • 50-degree roof pitch (for solar energy efficiency in winter)
  • The basement should be designed to eventually allow for a small separate living unit
  • Both bathrooms should have a standing toilet or urinal
  • We definitely want a windbreak/entry vestibule
  • The terrace should be raised with fill
  • Underfloor heating with geothermal energy
  • Solar energy planned for the future

We have already developed a fairly comfortable floor plan with our chosen architect. Our biggest concern is accidentally planning a wall or something else 5 cm (2 inches) too far to the left or right and then being unable to fit our furniture. I would appreciate it if you would be interested in looking over the current design and giving feedback.

Why are you planning the attic without underfloor heating? What kind of living spaces are planned there? Post 113 is also very confusing. It’s always recommended to create a separate post for each variant in the thread. And to label the rooms.

Okay, I will redo this and make a separate post for each variant. I thought it would be easier this way to compare the two options (back and forth).

Regarding underfloor heating in the attic: the architect gave a reason, but I can’t recall it clearly right now. The upper floor definitely has a wooden beam ceiling. Maybe it was because of that and/or the roof pitch. Two children’s bedrooms are planned up there for sure. Currently, the plan is to install slightly larger radiators in each room (due to the lower flow temperature of the heat pump). I would prefer a concrete ceiling and underfloor heating, though. I wanted to ask what the disadvantages of that would be.

Here is the architect’s proposal.
There are two children’s bedrooms in the attic.
All other rooms, except for the cloakroom/entrance area and bathroom on the upper floor, are labeled.

Why is there no door between the hallway and the open-plan room? You should try furnishing the open-plan space. I find that quite challenging.

The master bedroom is very tight with a rough construction dimension of 333 cm (131 inches). The bed with frame is about 210 cm (83 inches), and a wardrobe with doors is about 66 cm (26 inches) (Pax with sliding doors), leaving only 57 cm (22 inches) for passage.

Attic floor – where is the sloped ceiling? Does the shower fit in the corner? If the 2 m (6 ft 7 in) line is supposed to be there, it might become very cramped.

A site plan with the garage marked would be helpful to understand why the entrance door was moved. That immediately reduces the wardrobe space by 90 cm (35 inches).
