Four bedrooms plus a living room suit large families, or anyone who wants to set aside a room as a study or guest room. Our catalogue has five different 4+1 models: two single-storey and three duplex. This article brings together their prices and how they differ.
Single-storey 4+1 models
| Model | Area | Rooms | Baths | Price | Price per m² |
|---|---|---|---|---|---|
 129 m² single-storeyBYC 129 | 129 m² | 4+1 | 2 | TRY 1,175,000 | TRY 9,109 |
 166 m² single-storeyBYC 166 | 166 m² | 4+1 | 2 | TRY 1,350,000 | TRY 8,133 |
The 129 m² model (BYC 129) is our most compact plan with four bedrooms on one level. The 166 m² model (BYC 166) is the largest house in the catalogue. If you want a large living room, a big kitchen and comfortable bedrooms, and your plot is big enough, this is the first model to look at.
The biggest advantage of a single-storey 4+1 is that it has no stairs. In homes shared with elderly relatives, this can matter even more than the floor area. The downside is the footprint: a 166 m² house takes up more than 166 m² of ground, and the concrete slab grows accordingly.
Duplex 4+1 models

In duplex 4+1 models the living room and kitchen are downstairs, and most of the bedrooms are upstairs. Because they fit the same number of rooms onto a smaller footprint, they stand out on urban plots or on plots where zoning limits the footprint. Having more room left for the garden is another plus.
Why is the m² price lower for a 4+1?
Since the 4+1 models are the largest houses in the catalogue, their price per square metre is also at the lowest level. On today’s list the m² price of 4+1 models is in the range of TRY 8,130 – TRY 9,110. For comparison, in the smallest models the figure is TRY 9,910 – TRY 10,280. The difference comes from spreading work done once per house, such as the bathroom, kitchen plumbing and front door, across a large area. You can find the detailed calculation in our article on working out the m² price.
A 4+1 or a large 3+1?
In the 130–160 m² range it can be hard to choose between a 4+1 and a large 3+1. Our catalogue also has duplex 3+1 models of 155 and 158 m². To decide whether to use the same area for three large rooms and a big living room, or for four standard rooms, ask yourself: will the fourth room be used every day, or only a few times a year for guests? If it will be used occasionally, a large 3+1 usually makes a more comfortable home. The 3+1 options are in our article on 3+1 prefab house prices.
Items that push up the budget in a large house
In a large house such as a 4+1, some items outside the list price grow with the house:
- Concrete slab: The slab for a single-storey 166 m² house is noticeably bigger than for a 153 m² duplex.
- Ceramic tiles and floor coverings: Calculated by the square metre.
- Heating and cooling: More rooms mean more air conditioners or radiators.
- Transport: Large models mean more panels; the number of trucks is confirmed in the quote.
The full list of items not included in the price is on our page about what the price does not include. To work out the total, follow the steps in our article on calculating the total budget.
Conclusion
If you don’t want stairs and have a large plot, choose a single-storey 4+1. If the footprint is limited or you want to leave room for a garden, choose a duplex 4+1. You can find current prices for all the models on our prefab house prices page.
