A house that touches the land lightly: six principles for building in the forest

Most people who want to build in nature want the same thing: to keep the silence, the view and the trees that drew them there. The paradox is that a badly designed house destroys exactly those things. The principles we followed for Kargalı House, in the forests north of Istanbul, apply to anyone thinking of building in nature.

1. Touch the ground as little as possible

A house's biggest impact on its site often comes not from the building but from the excavation and fill needed to place it. At Kargalı House a light, glass-floored volume floats above the ground, and the land beneath stays almost as it was. Less excavation means fewer retaining walls and less disturbed soil.

2. Treat the trees as design data

See the trees on the plot as reference points rather than obstacles. A tree survey made before design begins decides where the house goes and which tree appears in which window. No landscaping scheme can replace a mature tree for decades.

3. Direct the view

The hilltop at Kargalı offers views of up to 50 km in every direction. But a house that looks out equally on all sides can be tiring. Framing the view at chosen moments gives rooms their character: the place for morning coffee and the place for evenings can face different horizons.

4. Balance transparency with privacy

Glass brings nature in, but it also shows the inside to the outside. Kargalı House has no neighbours and no shared access, which made a transparent architecture possible. In a busier setting, the same effect can come from courtyards, screening trees or changes in level. With large glazed surfaces, solar control, insulation and visibility for birds need to be considered from the start.

5. Plan for self-sufficiency

A house in the forest is further from infrastructure than a flat in the city. At Kargalı, parts of the land are set aside for agriculture and food production, and a winter garden usable all year is an in-between space for plants and for living. Rainwater harvesting, solar power and on-site treatment are not luxuries in this setting but a sensible starting point.

6. Leave room for flexible use

Houses in nature often stand empty for part of the year. Kargalı House was designed to work as a set for advertising and film productions too, and became a source of income for the family. Flexible rooms, separate entrances and durable materials make it easier for a house to adapt as needs change.

What to watch for when building in the forest

• Forest boundaries and protected areas: find out the plot's distance from the forest boundary and the authorities' position early.
• Fire safety: managing vegetation around the building, non-combustible facade materials and fire-engine access belong in the design.
• Access: a road usable in winter and rain matters as much as the house itself.
• Maintenance: humidity, leaves and insects in the forest directly affect the choice of materials.

In nature, the best house is the one that shows the place more than itself.
