Dear home builders,

We are planning to build a single-story house, 8 m by 11 m (26 ft by 36 ft).

From the street side, the plot slopes down by about 1.50 m (5 ft), and it also slopes down from left to right by about 50 cm (20 inches). One of the 8 m (26 ft) wide gable ends runs parallel to the street.

Regarding the main entrance, there are two options: either the entrance is on the street side, where there is a slope of about 23 cm (9 inches) over a distance of 5 m (16 ft) between the street and the entrance. In heavy rain, there could potentially be a risk of water running from the street into the entrance area.

Or the entrance could be planned on the right-hand side, viewed from the street. In this case, the entrance would be 1.30 m (4 ft) higher than the driveway to the garage. This would mean no problems with water runoff during heavy rain.

The side entrance has the disadvantage that the building would need to be shifted 1.20 m (4 ft) to the left, otherwise the staircase to the driveway would extend too far into the driveway, preventing a car from passing by the stairs. Moving the building to the left would reduce the “sun garden” area on the southwest side by about 12 sqm (130 sq ft). The entire plot is 640 sqm (6,890 sq ft).

What would you choose? 12 sqm (130 sq ft) more sun garden but increased risk from heavy rain, or 12 sqm (130 sq ft) less sun garden but no risk of water problems? Thanks in advance.

This seems very theoretical to me. The rainwater from the roof is also drained, right? You connect a drain to that, which channels the water on the access path just before the front door. Then, of course, the entrance from the street to the eight-meter (26 feet) side. What does the groundworks contractor say?

Thank you for your reply, Nordlys. The discussion with the civil engineer is still pending. Good idea to connect to the rainwater drainage system.

12 sqm of how much?
1.20 meters (4 feet) wide of how much "sunny side"? (As if the sun doesn't shine anywhere else 😉 )

640 is the plot size.
The question is what remains in the end 🙂
So, the garden is on the left side, to the left of the house.
