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.

Matthias954112 Feb 2017 13:57Hello kaho 674, most of the others have the entrance on the side and are situated up to 1 meter (3 feet) or more below street level. Many houses seem to have a side entrance as a standard feature, likely adopted from a developer's design. The zoning plan for our house only allows a finished floor height of 200.11 meters (656.9 feet). The street is at its lowest point at 200.31 meters (657.6 feet). Since the house is 8 meters (26 feet) long facing the street, in principle water could flow from the street towards the house along this length without additional measures. The distance between the house and the street is 5 meters (16 feet). To the right and left of the house, the water would run down the property due to the slope.

There is a garden behind the house and, when viewed from the street side, also a garden area to the left of the house. If the house were shifted to the left due to the side entrance, about 12 sqm (130 sq ft) of this garden would be lost. The garden to the left of the house mainly receives morning sun, which we would like to preserve.

Matthias954112 Feb 2017 15:37YPG, I haven’t fully answered your question yet. If the house is not shifted to the left, there is approximately 5.40 m (17.7 feet) of space on the left side along the 11 m (36.1 feet) length of the house to the property boundary. If the house is moved 1.20 m (3.9 feet) to the left, the remaining distance to the property boundary on the left side along the 11 m (36.1 feet) length would be 4.20 m (13.8 feet). This means about 13 sqm (140 sq ft) less space, not the 12 sqm (129 sq ft) I mentioned earlier, since 11 times 1.20 m equals 13.20 sqm (142 sq ft). The size of the garden behind the house remains unaffected by this shift, of course.
