Dear Forum,

First of all, we would like to introduce ourselves. We are a family of four and have now found a nice sloped plot in NRW. We are aware that it is considered a "challenging plot" in terms of buildability, but we have fallen in love with the location and the view. It is a total of 390 m² (4200 sq ft) of building land, with green space extending behind the plot. Currently, it is occupied by two buildings, the front one of which is a listed monument requiring renovation. The rear building is in such poor condition that it must be demolished. Of course, the monument must not be significantly disturbed within its ensemble, so a modern flat roof is unfortunately not possible. However, I am hopeful that we can connect the monument with our planned new building by a joint or gap.

First, the current situation: the front house is the monument, which I intend to renovate and use as a home office/guest room.


The front house currently has two floors, but ceiling heights no longer meet our needs due to our height, so we plan, as far as possible, to remove some walls and the ceiling between floors to expose the beams.

Now to our planned new build. We are working with an architect we really trust, who has designed and renovated some truly excellent houses within our circle of friends.

Development plan / restrictions
Plot size: buildable - 390 m² (4200 sq ft), with green space behind
Slope: yes, ascending towards the rear, with an incline between 8 and 12 %, so the house will sit at the lower part of the slope. Unfortunately, the view into the valley can only be enjoyed from the upper floor due to buildings on the opposite side of the street.
§34 construction: “mixed neighborhood”, single and two-story buildings with flat and pitched roofs, some 2.5-story pitched roofs
Edge development: apparently quite common in the neighborhood. My architect is more optimistic than I am that edge development will be allowed.
Number of parking spaces: 1
Number of stories: two full floors + pitched roof
Roof type: pitched roof
Style: must integrate with the half-timbered monument for an overall harmony (please no historicism, I prefer modern architecture, perhaps with wooden cladding)
Orientation: The architect insists on building the eaves side facing the street because of window areas. I am unsure if this is possible due to boundary constraints, so I suggest a gable orientation as an alternative. I am particularly interested in your ideas here! We are still in the very first planning phase.
Maximum height / limits: 2.5 stories

Client requirements
Number of occupants: 2 adults + 2 children
Ground floor space needs: master bedroom, 2 children's bedrooms, 2 bathrooms, separate cloakroom, either at the rear (slope) or in the basement: laundry room, storage, building services
Upper floor: large open-plan kitchen and living area with garden access, fireplace, guest toilet
Office: combined with guest room
Occasional overnight guests per year
Open or closed architecture: open plan
Traditional or modern design: modern
Open kitchen with island
Minimum dining seats: 8
Fireplace: yes
Music/speaker wall: no
Balcony, roof terrace: no
Carport

House design
Not yet available, we are still assessing the basic buildability
Designer: architect versus own ideas
Personal budget for house including fittings: initially open, we want to see what is possible
Preferred heating system: heat pump

If you had to give up something, which details or features
- can you do without: -
- cannot do without: large window front facing the garden with direct garden/terrace access

Here is the architect’s first concept. She assumes basic buildability including edge development and therefore wants to place the new build with the eaves side directly adjacent to the neighbor. I would prefer a longer joint/gap, but that would make the edge building length disproportionate. I find that unfortunate as I would like the new building positioned further back in the plot to create a larger front courtyard. This is the first idea currently being checked for feasibility by the building and monument authorities:

Site plan of a building plot with parcels, buildings, and access roads


The extension toward the garden is optional and designed with a flat roof.

My idea would be to extend the building joint further, placing the entrance and cloakroom there, with the new building accessed above. This new building would be rotated to face with its gable. Because it would extend far into the slope, the ground floor would effectively become a basement, and the upper floor would have direct garden access at ground level. I would also need to encroach on the neighboring boundary, but I imagine this might be simpler as I am only planning a single story there. Would the house then have enough windows? You don’t want to orient large window fronts too much towards neighbors, but at least toward the garden I would like to have a large gable window area.

Thank you very much for your suggestions! What do you think is feasible? What are the pros and cons?
I am also still looking for a contour map. All the maps I find online are somewhat coarse. Is there an online resource for NRW? What options should I select in the NRW geoportal to get a good detailed representation?

I forcibly cleared the overgrowth. The weather was moderate, and with work gloves on, the photos didn’t turn out very well. I will share better photos and images from improved angles later. You already know the two houses from the front. First, here’s a view from the very top of the property through the thicket. In the very foreground is a roof belonging to a shed that needs to be demolished. Then you can see the gable with wooden cladding of the listed building. Next to it is the roof of the house to be torn down. Behind that, you can see the street and the mixed surrounding buildings.

Now the demolition house from the back. Here, I would probably need to build partly into the slope. You can see the neighboring house directly on the boundary. Either build directly next to it or plant a nice garden...

When I mentioned left and right in the previous post, I was referring to the view from the street. So, left is the northern neighbor, right is the southern neighbor.

Is this a single-story extension on ground level, as well as the courtyard at ground level? Or would this already be the (planned) upper floor?

Currently, it is still at ground level. However, it faces directly onto a slope, which makes it quite dark. Since I expect to build further into the property, the lower floor would likely be embedded into the slope. This would allow building one floor higher.

That’s exactly what I wanted to know. You have to see where the slope begins.

Sorry if I missed it: What is your budget again? Have you already purchased the plot of land?

Are you trying to save us? Well, the plot is already ours. I don’t want to set a strict budget yet because I first wanted to see what is possible for which amount. Ideally, I wouldn’t want to exceed 700,000 (700k). If it’s necessary and there’s no other way, we’ll have to push through... I’m also concerned that the landscaping will add about another 20 percent on top. There should still be some subsidies available for the historical building (which, of course, are peanuts compared to the total sum). But luckily, the costs for the historical building and the courtyard area, etc., can be tax-deducted up to about 90 percent, even for private use.
