ᐅ Seeking Creative Ideas for Building on a Sloped Site

Dear forum members,

We have a sloped plot with access from the top, approximately 20m (65 feet) wide and about 45m (148 feet) long. It becomes flatter at the bottom, and the slope at the top is about 15%. The slope runs from east to west, and the previous owner already excavated a terrace

across the entire width decades ago. The neighboring houses also have terraces built up to this level.

Since we are a family of four and the house also needs to include a respectable commercial space for customer visits, we will probably need at least 200 sqm (2,150 sq ft).

I’m not too keen on the idea of building a three-story tower with 70 sqm (750 sq ft) per floor there. On the other hand, given the width of the plot (we also need space for a garage and carport) and the slope, we cannot fit the rooms we need into just the basement and ground floor. If we build too far back, there will be hardly any garden left on the terrace.

Do you have any more creative ideas on how to work with the slope so that a small garden can remain? Or is the tower our only option?

Our budget is about 650,000 solely for the house. However, for some trades, we have good conditions because family businesses are involved.

Right now, I am mainly looking for some ideas before we meet with an architect. We are very open regarding the implementation.

North is at the top. Approximately the upper two-thirds of the plot are allowed for construction. By plateau, I mean that the neighbors have filled up the first upper third, so there is a flat lawn starting from the basement level. The plateau,

This is where my patience for planning runs out if I don’t at least know the property from photos or have access to the building permit / planning permission.

The original poster definitely has the chance to provide more information here. 😉

It shouldn’t be that difficult to mark the heights on the plan themselves.

I would like to provide the contour lines, but so far we only have an old, yellowed development plan where the lines are difficult to make out. I assume there are four contour lines, but I don’t know their exact values. It is estimated to be a slope of about 15%. Since the road is downhill, the slope is slightly steeper in the south than in the north. Unfortunately, I don’t have any more information at the moment.

If you are not familiar with your land, you cannot plan properly. First, do your homework and then come back.

Depending on the federal state, you can find a lot of information about properties in geoportals.

A photo of the zoning plan excerpt can often convey more than you might think. Definitely better than nothing. Gather information. Obtain a topographic map? Use the geoportal to locate your plot. A photo taken on site often helps as well.

Is the street on the right? In which direction does the street slope? In which direction does the terrain slope? What does the zoning plan say about terrain modifications, building envelopes, wall heights, ridge heights, plot ratio (floor area ratio), floor space index, fixed finished floor heights, driveways, garages, carports, outbuildings, ridge orientation, fences, retaining walls, and so on?

Do the contour lines show the plateau?

How did you measure the 15%? Your sketches indicate much more?

We have searched the geoportals but found nothing. I will still try to obtain the necessary information.
