Hello everyone,

I’m new to the forum and have already found some valuable tips here. My wife and I have purchased a plot of land in Brandenburg, south of Berlin. We plan to contact the first construction companies in February, work on the planning, and aim to start the building phase by the end of the year. Our goal is to move into the bungalow by January 1, 2024, at the latest.

Our ideas for our own home are already quite well developed. At the moment, we have two main questions: Is our project feasible, and if so, which local construction companies would be suitable in the area? Perhaps some of you can offer valuable advice. We thank you in advance for your time and support. Below, I would like to present our design while considering the list of questions. The floor plan is also attached, and I hope it uploads at the same quality as the original image file I have.

Development Plan / Restrictions
  • Approximately 763 m2 (8,210 sq ft) with a 23.41 m (77 ft) frontage and 32.58 m (107 ft) depth, facing northwest.
  • Construction according to development plan
  • No slope on the land
  • Site coverage ratio = 0.4 (may be exceeded by 50% due to garages, parking spaces with access routes, and ancillary structures as per § 14 of the Land Use Ordinance)
  • Floor area ratio not specified
  • Building envelope
    • Building setback 4 m (13 ft) from street boundary line
    • Building area: 23.41 m (length) x 20 m (depth)
    • Protrusions up to 1.5 m (5 ft) allowed beyond building boundaries (pillars, cornices, roof overhangs, balconies, loggias, terraces, entrance steps and their coverings)
  • Boundary construction
    • Buildings allowed with side boundary setback and maximum length of 20 m (66 ft)
    • Setbacks and distances according to § 6 of Brandenburg Building Regulations (BbgBO)
  • Parking spaces, garages, and ancillary structures as per § 14 of the Land Use Ordinance are not allowed on non-buildable areas of the plot within 5.0 m (16 ft) measured from the street boundary line. For more than one parking space, an uncovered space may be located on the access area at a minimum distance of 3.0 m (10 ft) from the street boundary.
  • Number of permitted full stories = I-II
  • Construction method: variant "a"
  • Maximum roof pitch 30°
  • Roof covering
    • Tiles and roof slates, flat and shaped metal sheets and strips, flat slate shingles, and green roofs
    • Solar thermal and photovoltaic systems permitted
    • Permanently shiny and glazed roof surfaces are not allowed
  • Landscaping requirements
    • Driveways, parking spaces, and other ancillary areas must be constructed with water- and air-permeable surfaces
    • Rainwater must infiltrate on-site
    • At least one nesting aid must be installed on each residential building
    • At least one tree with a minimum trunk circumference of 10 m (33 ft) must be planted every 18 m (59 ft) of plot frontage within 5 m (16 ft) of the street boundary
    • An additional tree with a trunk circumference of 10 to 12 m (33 to 39 ft) must be planted on each plot

Homeowner Requirements
  • A single-story, nearly square bungalow without a basement, with a hipped roof
  • Construction method
    • Solid and monolithic
    • Stone: Sandstone for sound insulation, but since we definitely do not want external insulation (ETICS), this is not possible; we will use the stone type that the builder is most experienced with; based on research, we prefer perlite-filled bricks, but expanded clay types are also acceptable
    • Exterior plaster: Whatever the builder has the best experience with, painted in a light smoky blue; no brick cladding
    • Roof: Cold roof (no attic use), so the ceiling must be insulated
  • Two people in their mid-30s, planning to remain childfree
  • Guests per year: so far none, as this is just being made possible now
  • Currently planned living area approximately 172 m2 (1,850 sq ft)
    • An open living area including
      • Kitchen with island
      • Two dining areas (breakfast table for two and dining table for up to eight people)
      • Fireplace area with seating, wine fridge, and storage for fine beverages
    • A home cinema area with surround sound system, TV, large couch, and storage furniture
    • A bedroom with a 2 m x 2 m (6.6 ft x 6.6 ft) bed, two nightstands, and a dresser
    • A walk-in closet and dressing room
    • A bathroom with bathtub and T-wall for a large sink, shower, toilet, and two entrances
    • No guest bathroom, since we have no children, do not build for guests, our planned main bathroom will be nice, and guest visits will be rare and orderly; we consider a guest bathroom unnecessary for all these reasons
    • A multi-purpose room for mobile work, hobbies, and a pull-out sofa bed for up to two guests
    • A technical room with heating system, electrical connection, water connection, main utility connection box, and possibly a water softener
    • A utility room for washing machine, dryer, chest freezer, shelves, and work surface for small DIY tasks
    • Entrance area with built-in closet for shoes and clothing
  • Outdoor area with
    • Terrace with a maximum depth of 3 m (10 ft) wrapping around the left corner of the house, facing northwest and southwest
    • One parking space for one car, probably as a carport on the left; two spaces would be ideal if a second car is acquired, but this would likely require building on the boundary line on the right side, which we want to avoid; tips on enabling two parking spaces are welcome
    • Entrance: gentle ramp to the front door with no steps and no canopy
  • Window design
    • Floor-to-ceiling windows with black plastic frames in the open living area and bedroom, 35 cm (14 in) below the ceiling
    • Terrace door without threshold
    • Windows with black plastic frames in every room with a sill height of 87.5 cm (34 in) and 35 cm (14 in) below the ceiling; we would appreciate advice on whether this is suitable for the bathroom, dressing room, utility room, and technical room or if other heights would be better
    • All windows with external blinds (raffstores), with very good burglary protection and sound insulation
    • No aluminum window sills on the outside (they make noise in rain); materials are not yet decided
  • Front door without threshold, simple design with frosted side glass, very good sound insulation and burglary protection
  • Interior finishing
    • Room height after all construction work should be 2.60 to 2.70 m (8.5 to 8.9 ft)
    • Interior plaster: lime plaster, no lime-cement or gypsum plaster
    • Kitchen and bathroom tiled, all other rooms with light parquet (parquet to be installed by us)
    • Hi-fi room painted matte black, all other rooms painted white; no wallpaper in any room
    • Utility room initially concrete, will be tiled later
    • Technical room concrete floor
  • Technical systems
    • Heating systems
      • Ground heat collectors or ground source heat pump
      • Underfloor heating
    • Ventilation: manual
    • Water softener: probably yes, but we need more information before confirming
    • Photovoltaic/solar thermal: desirable if at no extra cost, but we are skeptical about payback; if someone can convince us otherwise, we’re open
    • Hot water storage tank: yes, since we prefer bathing over showering
    • No KfW (energy efficiency) subsidy, as we’re not convinced, but would like to know what we can achieve with our house

House Design
  • Own design made using HomeByMe
  • We particularly like:
    • That we were able to create a design at all
    • Separation of technical and living areas
    • Open large living area with kitchen, fireplace, and big dining table
    • Floor-to-ceiling windows in the living area
    • Barrier-free entry and exit with no thresholds
    • Separation of technical room and utility room
    • Living on one level (we are fit but want comfort and consider aging)
  • We do not like:
    • That prices and interest rates are rising and materials are in short supply, and we probably should have started building two years earlier
    • Our needs resulted in such a large living area
    • Two cars probably cannot fit side by side into a carport
    • Our ideas will probably lead to significant additional costs
  • We have not yet obtained a price estimate from an expert
  • Price limit for the house excluding land: 400,000 €
  • The plot was purchased recently and is being paid off with a variable loan that will be converted to a fixed construction loan

What can we give up?
  • We can give up
    • Living space, if a few centimeters can be saved here and there to reduce costs
    • Separation of utility room and technical room, if necessary
    • A poor-quality construction company
  • We cannot give up
    • Monolithic construction method
    • Separation of home cinema and living area
    • Open kitchen with island
    • Floor-to-ceiling windows in the living area and barrier-free house entry
    • Bathroom design
    • Dressing room
    • Fireplace
    • Excellent burglary protection

What can we give up?
  • Living space, if a few centimeters can be saved
  • Separation of utility room and technical room, if not feasible
  • Poor-quality construction company

Why is our design like this?
  • We thought carefully about what we absolutely want and then started planning accordingly
  • The design feels very right to us

Main question

Is our building project feasible according to the development plan, our specifications and wishes, and within our budget? If yes, with whom?

We look forward to your feedback and are open to honest criticism because only that will help us move forward and open opportunities we may not currently consider due to being perhaps too convinced of our floor plan.

We are currently looking for both local and larger construction companies for a project south of Berlin. We would appreciate any tips on companies that can realize such a project (especially a bungalow). If necessary, private messages are also welcome.

Thank you in advance for all your efforts.

Should this sentence provoke me? – after all, prefab / solid construction and architect or construction manager are not opposites, but can be successfully combined (as I have actually mentioned quite often).

Definitely not to provoke. I probably phrased it a bit imprecisely.

My point was more that some people wonder whether to work directly with a general contractor, while others prefer to start or even work entirely with an architect. The fact that everything can be designed and executed so individually is good in one way, but it certainly makes the decision-making process more difficult for someone without experience. After some research, my wife and I now feel more comfortable starting with an architect.

Regarding solid/prefab construction, these are mutually exclusive. As I said, I’m a layperson. I always thought the distinction was either a prefab house or a solid house built stone on stone (with or without external thermal insulation composite system – ETICS / external wall insulation).

Architects’ schedules are sometimes fully booked more than 12 months in advance. A single-family house just isn’t very profitable; their calendars are filled with multi-family buildings and public projects, which are much more lucrative. For a single-family home, an architect has to invest a lot of time for a relatively small profit, and the clients tend to be demanding as well. That’s the current situation. Finding a good architect who is willing to take on a single-family house project right now is quite rare and difficult.

Good luck.


Thank you very much. Two architects have now responded positively and want to talk with us. I think the workload can vary from region to region. Both are architects who primarily focus on single-family homes.

Maybe we can exchange messages about this via PM. We are located very close to each other regionally, and unfortunately, our experiences have not been as positive. 🙁 Thank you.

Let's put it this way: building with architects is like having a tailor-made suit for your home. Most people don’t have the income or the need for tailor-made solutions. Good ready-to-wear options are often sufficient. And those are the prefabricated houses.

That’s why you’re here, to learn something ;-)

“Solid” and “prefab” are marketing buzzwords used by manufacturers. The adjective “solid” is meant to emotionally suggest that only a masonry house could have allowed the three little pigs to resist the big bad wolf. The term “prefab” is a retort used by timber frame panel builders, ironically referring to the few weeks between delivering the wall panels and the arrival of the moving truck.

The cheap trick of doing most of the shell construction off-site, out of sight at a secret location (Jean Pütz would have said: “I’ve already prepared something there”), can be done not only with timber frame panels but also with precast concrete panels, expanded clay panels, or even brick-by-brick construction using porous bricks.

“Solidity” simply means that the material is “solid” throughout—strictly speaking, this applies even more to solid wood houses (not to be confused with engineered lumber) than to masonry with porous bricks (because of their hollow chambers) or aerated concrete (basically a rigid foam). Homeowners are private buyers driven by emotion, and salespeople know how to exploit that. Objectively, no construction method is a savior—but neither is it a disaster.

My personal amusement over the apprentice joke of pimping up load-bearing interior walls as if they were exterior walls, using a “Wonderbra” principle, is assumed to be known here. By the way, the wall design of a typical timber frame panel “prefab” house could be described in marketing jargon as an “integral insulation system,” since it essentially includes insulation between the studs.

The wheel has not become any rounder over the millennia; if you put aside the emperor’s new clothes, you’re basically always building the same simple house, even if it’s the “Nikolaus house” or the “Nikolaus Diestelmeier house” from the savings bank ad. Versions 2.0, 4.0, Superior Enhanced Blue Turbo: all smoke and mirrors—the core truth always comes from the same modular system, whether arranged horizontally or vertically. The job of marketing is just to obscure the fact that industrial products are ultimately made with the same basic ingredients.

You’re familiar with a relay station, of course.

Is that really the case? I don’t see any clear trend indicating that building with an architect is more expensive. I often hear that with smart planning and when the homeowner knows what they want, and the build isn’t extravagant or overly luxurious, it can be no more expensive—or even cheaper—than building without an architect.

Maybe this is because many people hire architects when they want expensive upgrades, a high level of customization, and costly materials. My feeling is that the market is simply so opaque that it’s difficult to make definitive statements here.

When I read such sweeping claims, I’d like to see solid, well-founded arguments that convince me.
