Hello everyone,

We have our first appointment with the architect on Wednesday evening. In the meantime, we have started experimenting with our ideas using Sweet Home 3D and want to bring these to the meeting on Wednesday. What do you think about the room layout and design? The living area is planned to be around 140-150 sqm (1507-1615 sq ft). The listed square meters on the floor plans include both exterior and interior walls according to the program. If I have calculated correctly and subtract the exterior walls and about 15% of the foundation size for the interior walls, you end up with roughly 150 sqm (1615 sq ft) of net living space. The foundation here measures 11 x 13 meters (36 x 43 feet). For now, we are mainly focused on the room arrangement and design. We are building on a slope, which means we will drive straight into the garage, and the property slopes downward along with the house.

Between the vestibule and the pantry, as well as between the vestibule and the hallway, we are considering using internal sliding doors.

We also wanted to ask who has placed their main bathroom with toilet, shower, and bathtub in the basement? Because of the sloped site, wastewater from the toilet, shower, and bathtub would have to be pumped back up to street level. There would be a height difference of about 2.5 meters (8 feet) to overcome. We are wondering if this is possible with a pumping system and, importantly, what the costs might be.

Background: We are building on a slope so that half of the basement can be fully used as living space because it is partially above ground. Since we always wanted a bungalow but need a basement, the option of a ground floor with a livable basement area is the best solution for us. We could also build two full floors on the property, but with a basement (half of which is above ground at the rear), it would look too bulky. The house is intended for two adults and one child, and we are planning to install a photovoltaic system, an air-to-water heat pump, and underfloor heating. The house will be built to KfW 55 standards. The slope means there is a height difference of 3.4 meters (11 feet) over a property length of 32 meters (105 feet).

We are very early in the planning process and are using the software for the first time, so please don’t be too harsh if something seems completely unreasonable or confusing.

Thank you in advance for your ideas and suggestions!!!

Homeowners should know what they want.

This is what you communicate to the architect.
Or do you really think the client wants an open-plan kitchen, dining, and living area?

Hello, sorry I didn’t see the questionnaire earlier. A site plan and pictures of the plot will also be provided.

Development Plan / Restrictions
Size of plot – 717 sqm (7,715 sq ft)
Slope – yes
Floor area ratio: 0.35
Gross floor area ratio: 0.70
Building window, building line, and boundary – see plan
Number of parking spaces – double garage
Number of floors: maximum 2
Roof type – hipped roof / gable roof

Owners’ Requirements
Basement, floors – basement yes, if possible a bungalow with basement
Number of people, ages – 2 adults, 1 toddler
Room requirements on ground floor, upper floor – total living area 130-140 sqm (1,400-1,500 sq ft)
Office: family use or home office? – family use (guest room and study)
Guests per year – 4
Open or closed layout – undecided
Traditional or modern style – modern
Open kitchen, kitchen island – open
Number of dining seats – 4-6
Fireplace – no
Music/stereo wall – yes
Balcony, roof terrace – balcony no, terrace yes
Garage, carport – double garage
Kitchen garden, greenhouse – no
Additional wishes / special features / daily routine, also reasons why something should or should not be included – walk-in pantry accessible from the entrance hall and kitchen, entrance hall

House Design
Who created the design: owners
- Planner from a construction company: architect belongs to the company
- Architect – belongs to the company
- Do-it-yourself – no
Personal budget for the house, including fittings: €450,000
Preferred heating system: air-to-water heat pump

Why is the design the way it is?
Because we wanted to prepare for our meeting with the construction company and their architect to clearly show what we want.

What is the most important/fundamental question about the floor plan in 130 characters?
Is it sensible to have bedrooms, children’s room, and bathroom in the basement, or better on the ground and upper floors?

The house is larger than 150 sqm (1,615 sq ft).

Living/dining/kitchen areas face the garden. I would switch the floors. Remove a few corners.

So far, we’ve had appointments with various construction companies, and they always said you need about 11 x 13 meters (36 x 43 feet) to reach 130–140 sqm (1,400–1,500 sq ft) of living space. They also mentioned that interior walls account for around 15% of the slab size, and exterior walls must be subtracted as well. That’s why we adopted this size for now.

The street is located above the house. We were always told to put living spaces on the upper ground floor since you can access it directly from the garage, and bedrooms on the lower floor because those rooms stay cooler in summer.

The southeast side is on the right side of the house, so we planned the living/dining area on the right and the garage and main entrance on the left.

Why switch the floors?

Please don’t bring your plans to the architect. Let the professional surprise you. In a restaurant, you also let the chef do the cooking.

Over the past few weeks, we had appointments with several construction companies. What we received so far based on our wishes wasn’t really constructive. However, through these discussions, we realized what is important to us and started to create something ourselves. The current architect belongs to the construction company we have chosen. This company is very well known in our area, and everyone we have spoken to has given exclusively positive feedback. Therefore, we thought it might help to show what we imagine not only in words but also with pictures.

Well, a lot of poor quality work also comes out of it. When I think about the proposals we have seen, you really have to be careful.

We have already visited several construction companies to get different quotes. What we have received so far wasn’t really great. So, we thought we’d try creating our own design ideas to better explain what we want. Whether this is feasible given the structural engineering, load-bearing walls, and so on, will have to be decided by the architect, but we thought this might help to communicate our expectations more clearly.

Kitchen is way too small. In the pantry, the salad leaves have to be pinned to the wall to leave enough standing space. Meanwhile, there is room for two full bowling lanes between the dining table and the sofa, and you can easily play mini golf in the hallway.

Overall proportions are very unbalanced. Cabinets seem much too small on the plan. You can comfortably plan wardrobe furniture to be 60cm (24 inches) deep to be able to hang several jackets side by side.

Connect the kitchen, dining, and living area to the basement level facing the garden, and have the bedrooms upstairs. Families often go together to the garden for meals, playing, etc. And for dining, the kitchen needs to be nearby.

Is the driveway to the garage coming from the northwest, meaning from the left side of the plan?
