Buying a flat: check the location in 5 minutes

When you buy an owner-occupied flat, you buy the location along with it, and for good. Five minutes with the official data tell you more than three viewings in sunshine.

Seven questions before the viewing

The checker shows which data SunPlot can use at this address. No sign-up, no purchase.

Why five minutes are enough

For an address, SunPlot calculates the sun every 10 minutes throughout the year with the 3D model of Switzerland and overlays all official maps on the property. You enter the address, choose the floor and see: hours of sunshine, annual overview, cast shadows at any time of day, view, noise, zones, hazards, public transport. Anything left open you clarify at the viewing with targeted questions to the seller or the property management.

Overview of hours of sunshine from a SunPlot report
Overview of hours of sunshine for the chosen floor: reference date, first and last sun, winter, summer and year.

Also check with condominium ownership

  • Regulations and minutes of the owners’ meeting, balance of the renovation fund.
  • Upcoming renovations to the roof, façade, heating and lift.
  • Rules of use for the balcony, seating area and parking spaces.
These points are part of checking the property and the legal situation, not the location. The report covers the location; for regulations, fund and structural condition, the property management, notary and building experts are responsible.

Short answers

What should I check about the location when buying a flat?

Floor and façade, winter sun, evening sun on the balcony, noise on the bedroom side at night, view and building zone opposite, public transport access as well as flooding and surface runoff for the cellar and underground car park. All from official data for every address in Switzerland.

Can I check the sun for a specific floor?

Yes. In the SunPlot report you choose the ground floor, an upper floor or the roof. Hours of sunshine, the annual chart and the view are calculated for that height.

Is a south-facing flat automatically sunny?

No. South is only the direction in which the sun could be. Whether it actually reaches the flat in winter depends on the house opposite, the slope and trees. A twelve-metre building casts a shadow of around 34 metres at midday in winter.
