A two-bedroom flat is what most families look for and the most versatile format for resale. It is bought as a first family home and as the natural step up from a one-bedroom when a child arrives.
On the resale market most of the stock is 1970s and 80s panel and brick housing of around fifty square metres. In new developments two-bedroom flats start from about sixty and almost always come with an open-plan kitchen-living room. These are two different ways of living, and the choice should follow how you actually use space rather than the price per square metre.
New builds offer more space and open-plan kitchens; resale offers a lower price, established infrastructure and no waiting for completion.
Only at a clearly lower price. They are harder to resell, and reconfiguring a panel building is not always permitted.
One with two separate bedrooms close to transport, those are taken by families on long tenancies.
Layout is the decisive factor. Flats where one room passes through another are noticeably cheaper and harder to resell. If the budget allows, separate rooms are the better buy even at a smaller total size: you get a real second bedroom and the layout holds its value.
Second, window orientation. Windows facing different directions make a flat easier to live in through the summer, especially without air conditioning. Third, before paying a deposit check whether the flat has been altered and whether those changes were registered, an unapproved kitchen-and-room merger causes problems at resale and with mortgage approval.
