1+1, 2+1 or 3+1? How to choose the right flat size in Turkey

In short

The right size matches both your needs and demand in the neighbourhood. A 1+1 suits a student or a couple and rents easily near universities; a 2+1 is a balanced choice for a small family and for investment; a 3+1 is the most popular with Arab families; and a 4+1 or duplex suits large families and long visits. A bigger size means higher fees and heating costs, and sometimes narrower rental demand.

“How many rooms do we need?” sounds like a simple question, but it determines your budget, your monthly fees, the kind of tenant who will knock on your door and how fast you can sell later.

What do the numbers mean?

The first number is the number of bedrooms; the second is the number of living rooms. See the guide to reading property listings.

Common sizes and approximate areas

The following areas are net and approximate, and vary from project to project:

  • 1+1: about 50–65 m².
  • 2+1: about 75–100 m².
  • 3+1: about 110–140 m².
  • 4+1 and duplex: 150 m² or more.

Always compare by net area. See the guide to net and gross area.

Which size suits whom?

1+1

A student, a couple, or an investor near a university. Easy to rent near demand, with lower fees.

2+1

A balanced choice: a small family, or one bedroom plus a guest room, with broad rental demand.

3+1

The most popular with Arab families: a room for the parents and two for the children, and well suited to summer visits.

4+1 and duplex

Large families and long visits with relatives. A narrower audience when selling or renting.

Considerations for Arab families

  • The living room: is it big enough to receive guests?
  • A guest room: useful during summer visits.
  • The kitchen: closed or open? Many families prefer a closed kitchen.
  • Bathrooms: at least two in a 3+1.
  • Storage: enough cupboards for the family.

Size and costs

Size and investment

Choose the size most in demand in that particular neighbourhood, not in the city in general. Ask: who rents here? Students, families or summer visitors? See the guide to living versus investing.

The bottom line

Choose the size you really need, with an eye on who will live there after you. For an Arab family, the 3+1 remains the most common choice, the 2+1 the most balanced for investment, and the 1+1 for proximity to universities.

  • View, orientation and sun: why a sea-view flat in Trabzon may get less sunlight

    In Trabzon the sea lies to the north, so a flat that looks straight onto it faces north and gets less sun, and north-facing walls are more prone to damp. The best options are often a corner flat or one with two façades: a sea view to the north and sun from the south or west. A view raises value and demand, but check that it will not be blocked by new construction, and check the light and warmth in winter.

  • Video viewings: how to see a flat as if you were there, from your own country

    A live video viewing saves many trips if you lead it yourself: ask for one continuous, uncut tour; start from the street and the entrance, then every room, window and balcony; turn on the taps and open the cupboards; ask to see the view in every direction, the north-facing walls and the corners for damp, and the way to the nearest amenities. Record the tour and ask for the documents afterwards. For a property you will spend a large sum on, treat the video as a filter before a visit or a second tour at a different time.

  • Urban transformation in Istanbul: what it means for buyers and owners of older flats

    Kentsel dönüşüm (urban transformation) in Turkey is governed by Law 6306 on rebuilding buildings at earthquake risk. A licensed body’s report classifies a building as risky, and this is recorded at the tapu (land registry). Since November 2023, rebuilding decisions need an absolute majority of the owners’ shares instead of two thirds, and a February 2026 regulation changed the procedures, such as selling objecting owners’ shares. Owners may get rent assistance under conditions. Buying in an old building means buying a share of the land and a future project: read the legal position carefully.
