This competition looks for proposals for a 2-storey, 3 Family new house in Darmstadt, Germany. The house will be part of a new neighborhood development. The house needs to be steel construction.
You can find the satellite image (FIG1) of the lot at:
The coordinates of the lot are: 49.932954, 8.746752
FIG2/FIG3 show the home’s lot in relation to the entire new development. The lot is number 21 and is shown with a red circle.
FIG4 shows my lot in detail, it is ONr.16. Some specifications:
Width = 18m
Length = 25m
Total Area = 450m2
However, we can only use 35% of the lot, which is 157,5m2. (The rest 50% landscape, 15% hardscape.)
The maximum building area we are allowed is 140m2, the remainder of usable area --17,5m2 -- you may or may not use for a car garage.
The blue box in FIG4 within the ONr.16 lot shows the area you can use to build, there are the following setback rules:
Front = 6m
Left, Right , Back = 3m
The area of the blue box in total is 12mx13,5m= 162m2
You can place the building (and garage if you have) anywhere within this blue box, however, the closer the building is to the front street the better, since all plumbing electricity lines are on the street.
FIG5 shows is a basic scheme of the building. The total height of the building can be 10,5m. The height between the beginning of the roof and the ground floor can be 6,5m. The total height of the two floors do not have to be exactly 6,5m as in FIG5, for example, the roof can start 1m above the roof floor. The standard floor-to-ceiling height in Germany is 2,5m.
We want to dig about 1m to 1,5m below ground line. There is Arsen in the soil, therefore the entire lot will be covered 60cm with additional soil (see D in FIG5). If the basement is 1m below ground level, and later on the ground is raised by 60cm, the total below ground will be 1,6m. Also, you are allowed to have the basement sticking out 1m above the ground, that is in total that makes 1,6m+1m=2,6m.
It is up to you to suggest windows to the basement level or not – based on the program.
Entrance to House:
Since the entire home will be 1m above ground level, the entrance door needs a porch, FIG6 gives you an example of steps needed.
2-storey house for 3 families
You can divide the house into two equal units in plan: the right side can be a 2-storey unit for the client, whereas the left side can be a 1-storey unit for a tenant. In other words, the left side has one tenant on the ground floor and another tenant on the upper floor.
1. Left side (tenants side)
ground floor has 3-bdr apt
upper floor has 3-bdr apt with access to roof (roof has a bedroom w shower) and balcony
basement should be used as depot for client and 2 tenants, and if it fits needs a mechanical room for heating equipment
2. Right side (clients side)
- home theater
- hobby room
- small server room (1-1,5m x 2m)
- small swimming pool
- living room: ~36m2 with fireplace
- kitchen: ~18m2:
(one wall with cupboards) minimalistic (should almost appear as a wall)
should have an island w oven, and shelves
- Closet for kitchen
- WC (close to entrance)
- terace to outdoor garden
- glass path (see FIG12) from entrance door to living room – open for suggestions
- master bedroom 20m2
- w private master bathroom (jakuzi) w 2 sinks, equipment to dry towels?
- 2xclosets (for clothes, shoes etc) -- men/woman
- 2 bedrooms, 15m2 each
- shower/wc for these 2 bedrooms
- access to roof w office space
Note: The living room should have a big opening towards the backyard. I would like to have probably a terrace at the backyard. Also, keep in mind that the house is elevated by 1m, but I would like to have the living room closer to the ground and backyard level, therefore the corridor may have steps going down to the living room which is at the backyard/terrace level – although I am open to suggestions.
Please see FIG7 for different types of roofs that are allowed. Roof needs to have an angle of min 30 degree (max 45 degrees). I would prefer the Option 1 in FIG7, and it would be great to have dormer(s) window openings, similar to FIG8, FIG9 and FIG10.
Green (sustainable) Architecture issues:
1. Cistern: We will be using rain water in the yards and the bathrooms. It is mandatory to have a cistern (see FIG11).
2. Solar panels on roof ?
3. Natural air ventilation for entire house?- air intake/outtake in each room
4. Geo thermal energy?
5. Passive energy strategies
We aspire to have a zero-energy home or at least have passive energy techniques applied. For more information about these types of buildings please visit:
