ᐅ Single-family Home Floor Plan Approx. 160 sqm – Suggestions for Improvement?

Created on: 21 Sep 2018 19:19

Hello everyone,

I am new to the forum, but have been following along for a while and have already gathered quite a bit of knowledge.
Attached are the floor plans for the ground floor and upper floor of a single-family house; I know the dimensions do not yet match the floor area ratio, this is just an initial rough sketch that I plan to refine step by step.

Here are the details:
Development Plan / Restrictions
Plot size: 500sqm (5400 sq ft), rear plot
Slope: No
Site coverage ratio: 0.2 → 100sqm (1076 sq ft)
Floor area ratio: 0.3 → 150sqm (1615 sq ft) excluding the bathroom on the upper floor
Building envelope, building line and boundary: only 3m (10 ft) distance to the boundary must be maintained
Edge development
Number of parking spaces: 2
Number of floors: 1.5
Roof type: single-pitch roof
Architectural style: modern
Orientation: southwest
Maximum heights / limits: eaves height max. 4.5m (15 ft)
Additional requirements: old development plan → bathroom upstairs and air space are not included in the floor area ratio; likewise, no sealed surfaces outside the building

Homeowners’ Requirements
Style, roof type, building type: solid construction, rather modern style, large windows
Basement, floors: no basement, 1.5 floors
Number of occupants, age: 2 adults, 1 child (3 planned in total)
Room requirements on ground floor and upper floor: see floor plan
Office: family use or home office? Home office 2-3 days per week
Overnight guests per year: 10
Open or closed architecture: open
Conservative or modern construction: modern
Open kitchen, kitchen island: kitchen directly connected to the dining room via sliding door
Number of dining seats: 6
Fireplace: yes
Music / stereo wall: no
Balcony, roof terrace: no
Garage, carport: double carport → 2 parking spaces as mentioned above
Utility garden, greenhouse: no
Other wishes / special features / daily routine, also reasons why certain things should or should not be included: gallery window from ground floor to upper floor → I know galleries are not very popular here, but we like this very much

House Design
Who planned it: self-designed using building brochures and impressions from friends’ houses as well as show homes

What do you like most? Why? Open living area; the heart of life and a meeting point; central stringer staircase
What do you not like? Why? Corridor size on upper floor; it feels like wasted space as it is really just a hallway leading to the rooms
Estimated cost according to architect/designer: still open
Personal price limit for the house including equipment: 270,000 EUR (without electrical, heating, sanitary, and outdoor facilities) → land already deducted. We are building in northwest Germany
Preferred heating technology: heat pump

If you have to give up, which details or extensions
-can you give up:
-can you not give up: size of the walk-in closet due to the size of Ikea Pax wardrobes, gallery window, shower in the ground floor bathroom, external blinds on the ground floor

Why did the design end up the way it is?
A mix of many examples from various magazines...

What is the most important / fundamental question about the floor plan summarized in 130 characters?
I’m looking forward to your opinions and would appreciate suggestions for improvement J
For now, I have left out the windows, as we are still at the very beginning and it is only about the spatial layout...

Thanks in advance for your help and best regards
Karina

I'm sorry, but I haven't planned that many houses yet.

We have pointed out many defects to you. At least these should be resolved in the further design.

That is why we keep saying: graph paper and pencil, so you can focus on the design instead of the software.

Also about the refrigerator: it could be integrated into the kitchen unit

But it’s not here. And if it were in the drawn kitchen unit, no one could move in the working area. When you can already see while drawing that something is too tight, you have to change it—if necessary start over completely and try a completely different approach.

No, with an architect you only go in with a written room program. Why should a layperson tell a professional how to design the house? Unless you have a natural talent, understanding, and a sense for spaces.

Sorry, but we mean well.
But you also need to answer the questions...

There isn’t an exact bed yet, nor the child associated with it.

But when the child arrives, they will grow—and as a tall sixteen-year-old, they will still need a bed in the family home. A child’s room does not mean "a crib is enough"; fundamentally, it needs to accommodate an adult-sized bed.

But before I approach a contractor or architect, I would like to have our ideas somewhat put down on paper.

However, these ideas shouldn’t be so widely off that the house would have to be two meters (6.5 feet) longer and wider to realistically fit furnished rooms.

Unfortunately, I can’t plan a roof with this,

No, but you can use a protractor and calculator on graph paper to figure out where the 2m (6.5 feet) standing height line will be.

Do you think a gable roof is better for a plot and orientation like this?

Those broken gable roofs (also known as offset shed roofs) were popular during the heyday of Depeche Mode and Kim Wilde, with bands of windows. Without those windows, they are basically pointless—unless you use them to shift the wall under the ridge beam off the central axis. But as a design for its own sake, they’re unnecessary. A classic gable roof is timeless; it suits a respectable house for any occasion.

An offset shed roof will cost you 10,000 euros more (as of 2013).

The key issue is not that you are inexperienced with the software, but rather that you don’t have a clear understanding of knee wall height, roof slope, gable, etc.

Here is a quick sketch of the master bedroom and bathroom from your upper floor plan with approximate values; the window positions are the critical factor here.

Roof pitch 45° with an actual knee wall height of 111 cm (44 inches) inside.

Floor plan of a building section with three rooms (1–3), exterior wall and section A-A.

Roof pitch 38° with about 90 cm (35 inches) knee wall height (I unfortunately didn’t keep the knee wall height consistent).

Architect’s plan: Floor plan of a house with three rooms (rooms 1–3) and section A-A.

As you can see, in both cases the window needs to move further to the right, because if roller shutters or similar are to be installed, the window can only start where the full ceiling height in the story is reached.

You can also see the two dashed lines in the roof: the first always indicates the 1-meter (3 feet) mark — which fits and lies within the wall structure — and the second shows where a 2-meter (6 feet 7 inches) ceiling height is reached.

--------------
Although the building in the sketch is not as wide as in your example, I expanded the roof width to roughly match the data.

... Kerstin's drawings also show you that the corner in the bathroom can only serve as a dust collector. A toilet or shower is not feasible there.

Perhaps the original poster is not fully aware of this: as Yvonne already mentioned, as a client you only provide a list of the rooms you want, your plot of land, the zoning plan or building regulations, your budget, and maybe some example houses from brochures or the internet that you like. Then you let the professional create a design for you. You can still tell them during discussions what you like and what you don’t. It’s best to share the resulting design here for further discussion. Doing it yourself requires a lot of experience or, better yet, an architecture degree, which probably takes too long before construction can begin.
