Buying a penthouse flat in Switzerland

A penthouse flat combines privacy, panoramic views and spacious rooftop terraces. If you are looking for peace, light and comfort in an urban setting, a penthouse flat will deliver just that – exclusive living above the rooftops of the city. For owner-occupiers, these types of properties can be a special retreat, while investors appreciate the stable demand and restricted supply in sought-after locations.

Buying a penthouse flat – benefits and ideal buyers at a glance

• Suitable for couples, families and seniors who want peace and quiet and a beautiful view

• Large rooftop terraces with exclusive rights of use, often with ideal sun exposure

• Lots of light, few neighbours; lift often opens directly into the flat

• Higher purchase and maintenance costs (roof, shade, building services)

Market overview: penthouse flats in Switzerland

The supply of penthouse flats is naturally limited, as roof space is rare. There are a total of 4’840’096 flats in Switzerland, with a vacancy rate of 1.01%. Large flats are particularly scarce: 5-room flats have a vacancy rate of 0.72%, while 6-room flats and larger have a vacancy rate of 0.84%. Penthouse flats often fall into these larger categories, with high-quality fixtures and fittings, which drives up the price and resale value – especially in cities and in suburbs with good transport links.

Costs involved in buying a penthouse flat

In addition to the purchase price, the buyer will incur notary and land registry fees and – depending on the canton – a transfer tax may also be payable. When buying an individual flat within a block of flats (STWEG), you will also have to pay ancillary costs and contributions to the renovation fund; costs for maintaining the roof, façade and lift account for the majority of the expenditures. Banks usually require a deposit of at least 20%; the cost of an affordable property should not exceed around one third of income, including imputed interest and ancillary costs. The rental value and the deduction of interest on debt are relevant for tax purposes; property tax may also be due. When the property is sold again at a later point, a capital gains tax on the sale is generally payable.

A step-by-step guide to deciding whether a penthouse flat is right for you

1. Define your needs and budget: rooms, outdoor space, location, public transport.

2. Obtain preliminary financing approval and organise your deposit.

3. Select listings; assess the floor plan, sunlight, view, privacy and noise.

4. Review documents: land registry, rules governing privately owned flats (STWEG), records and reports, renovation fund, energy certificate.

5. Check the condition of the property and its roof waterproofing; have the purchase agreement, payment plan and special rights of use reviewed by a solicitor.
