Hello everyone,
We are at the beginning of our house planning and we like hipped roofs.
The development plan (for a weekend area) allows only 75 m² (807 ft²) of footprint and a maximum roof pitch of 30 degrees on the main roof surfaces.
Does anyone know of a tool that allows planning how large the surfaces of a hipped roof can be for a given footprint and roof pitch? For the trapezoidal sides of the hipped roof (south-facing), I would like to use the maximum 30-degree pitch, as I want to install photovoltaic panels there (positioned on east/south/west sides).
I hope an online tool could give me a better idea of how big the roof surfaces might be, as I want to calculate how many (or how few) photovoltaic panels could fit, and whether the combination of a hipped roof and a photovoltaic system even makes sense for a small footprint.
A few more details:
Footprint: approximately 9 x 8 m (9 m (30 ft) on the trapezoidal side of the roof)
Slope: planned as a full story, a garden level, and a basement
South-facing orientation
Free of shading
Additional planned surfaces for solar modules with a double carport (also free of shading) and possibly a garden shed

I once heard that a hip roof would cost about 8,000 EUR more than a gable roof. After your post, I’m now reconsidering whether it might actually be better to go with a gable roof. I’m also planning to install solar panels on the double carport. It faces south (not shaded), which would fit well with photovoltaic modules on an east-west gable roof. The additional cost for a hip roof largely depends on whether the attic space will be used in any way that requires a traditional timber roof structure. A roof that serves only as weather protection can be built as a simple truss structure, which is why this option is so popular when the building is meant to be a substitute villa.

Are roof overhangs allowed? Is the sketch just schematic, or is there really such a slope? Roof overhangs of 80cm (31.5 inches) are permitted, and I would use them for heat protection and shading (very sunny location — the neighbors just moved in and are wondering how the heat will be in summer…). Apparently, photovoltaic panels also help reduce the house’s heat buildup.
The sketch is only schematic. The slope is about 2 degrees. Over approximately 8 meters (26 feet), there is a height difference of 28cm (11 inches).

And why don’t you want to convert the attic into living space?Well, according to the development plan regarding the sketch I posted earlier: 2.2.5. Maximum eaves and ridge height for gable and hip roofs:
Eaves height: 5.7 m (19 feet) above the top edge of the basement slab
Ridge height: 7.7 m (25 feet) above the top edge of the basement slab
This means that if you were to convert the attic, you could hardly stand upright except possibly under the ridge. Therefore, the attic could either be used as storage space or simply left open. This would make the living area – in this small house – feel somewhat larger.
We viewed a house in this weekend cottage area where the ground floor had a normal ceiling height, for example 2.40 or 2.50 m (8 feet or 8 feet 2 inches), in the entrance hall and guest WC (to the right of the hall) as well as a small office (to the left of the hall), and there was – only above this small section – a small storage space in the attic where you couldn’t stand upright. In the rest of the ground floor – kitchen and living area – the roof was open, and it looked great. We are considering this option. However, we are still unsure if we can do without the lost storage space.

Here are some photos of the neighbor. They have built on all 4 sides.Your photos of the neighbor are interesting to compare with Musketier (floor plan 10.2m x 8.2m (33.5ft x 26.9ft)). Do you happen to know the size of your neighbor's floor plan?Similar topics
