100 m² Prefab Home Prices 2026: Floor Plan Examples and Real Figures

Let’s start with the clear figure: as of 2026, the 100 m² two-storey 3+1 modular villa Villa Yuva is offered at ifHaus with a turnkey price starting from 2.249.000 TL. On the open market, meanwhile, anyone researching a “100 m² prefab home” runs into figures that differ by a factor of two or even three. The reason is usually not the products but the scopes: some prices cover only the main structure — the load-bearing system and panels — while others also include the exterior cladding, the window and door joinery, the interior finishes, and the kitchen and bathroom installations. That is why such a wide price range forms under the same “100 m²” heading, and why you need to know what each figure covers before placing them side by side.

In this guide we work with real figures specific to 100 m²: first the factors that determine the price at this size, then a table of current starting prices for ifHaus models at and around 100 m². From there we look step by step at how a 3+1 plan is arranged at 100 m² on one storey and on two, what the turnkey scope includes, what to watch for in cheap quotes and how cost per square metre is calculated. If you would like the full table across all sizes, our 2026 prefab home price guide is the companion piece to this article.

In Türkiye, 100 m² is one of the most researched size bands for family use, because it is among the first sizes that can carry a 3+1 plan comfortably. Yet two quotes for the same 100 m² can differ seriously. Five key factors produce that difference:

1. Storey configuration: 100 m² can be resolved on a single storey or across two. A two-storey layout adds a staircase, an intermediate floor and extra structural details to the cost; in return, the smaller footprint lets the home sit on a more compact parcel. On a single storey, the foundations and roof surface grow with the footprint; the cost balance between the two layouts varies by project.

2. Plan content: What generates cost is not empty square metres but what sits inside the plan. A 3+1 plan has far more partition walls, doors, windows and service points than a 1+1; wet areas such as the bathroom, WC and kitchen are the most expensive parts of a home per square metre. This is why even a 2+1 and a 3+1 at the same 100 m² end up costing differently.

3. Material level: The thickness and continuity of the thermal insulation, the façade material, the window systems and the quality of the interior finishes directly affect the price. Two homes that look alike from the outside can have very different technical specifications; that difference shows up not on the invoice but in daily life.

4. Delivery scope: A price covering only the main structure cannot be compared on the same footing with a move-in-ready turnkey price with the kitchen and bathroom fitted. Scope difference is the number one reason for the wide price gulf seen in 100 m² quotes.

5. Plot conditions: Transport distance, road access, ground conditions and infrastructure connections vary from project to project. These items are calculated per plot, outside the home price; that is why the same home can produce a different total budget on two different plots.

The table below lists the 2026 turnkey starting prices of the ifHaus models most often compared by people looking at 100 m²: the 48 m² Villa İz as a reference at the compact end, the 86 m² Villa Vadi as the closest alternative to 100 m², and the 100 m² Villa Yuva, the main subject of this guide.

When reading the table, we recommend looking at the number of rooms and the storey configuration alongside the total price. The 250.000 TL difference between Villa Vadi and Villa Yuva, for example, is not just a 14 m² difference in area; it is the sum of the things that shape daily comfort, such as room sizes, storage and the generosity of the shared living space. For those whose budget sits between the two models, the right question is not “which is cheaper” but “which suits my family scenario better”.

In a 100 m² 3+1, the real design question is this: should the space spread horizontally on one storey, or divide vertically across two? In a two-storey layout, the most common and most efficient approach is to plan the ground floor as the “daytime floor” — living room, kitchen, entrance hall and a WC — and the upper floor as the “night-time floor”, with three bedrooms and the bathroom. This separation naturally divides the shared spaces where guests are hosted from the family’s private areas; acoustic and privacy comfort follows of its own accord. The 100 m² two-storey Villa Yuva is designed on exactly this logic, with a generous shared living space on the ground floor and the bedrooms above.

In a single-storey 3+1, all the rooms sit on the same level, so the plan is resolved along a corridor. The advantage is stair-free, horizontal living that stays accessible at every age; it is ideal for families used to single-storey living and for older residents. The drawback appears at two points: circulation areas such as the corridor take a share of the total floor area, and a footprint of roughly 100 m² requires a larger parcel once the setback distances from neighbouring plots and the road are added.

The single-storey versus two-storey decision is therefore not just a matter of taste: if your parcel is narrow or small, a two-storey layout places 100 m² far more comfortably; if you have a wide, flat plot, single-storey horizontal living is a strong alternative. You can review the plan and façade details of Villa Yuva on the /modeller page and work through with our team which layout sits better within the dimensions of your plot.

Because “turnkey” is used differently from company to company, the definition needs settling first. At ifHaus, the turnkey starting price describes a home that is ready to live in: the load-bearing system and thermally insulated shell of the building together with the exterior cladding, the window and door joinery, the interior wall, ceiling and floor finishes, and the kitchen and bathroom installations. In other words, the 2.249.000 TL you see in the table is the starting price not of an empty shell, but of a 3+1 you can move into.

The items outside the price are the plot-dependent ones: the foundations engineered from the ground survey, transport between the production facility and the plot, electricity, water and sewerage connections or a septic tank solution, and the fees attached to the building permit and design stages. Because these items cost differently on every plot, they are not built into the standard list price; once your plot details are settled, they are confirmed item by item alongside the home price. A reminder: prefab homes are also subject to a building permit; we explain the steps in detail in our permit guide, and since the process can run in parallel with the production planning of the home, it costs the schedule nothing.

When planning the budget, the soundest model is to treat the home price as the fixed core and the plot items as the variable ring around it. That way, the answer to “what will a 100 m² home cost me in total?” rests on the data of your own plot rather than broad estimates, and no surprise items appear along the way.

When you see a figure noticeably below the market average for 100 m², the first thing to check is not the product visuals but the scope list. A large share of low-priced quotes are not so much misleading as the price of something different: a delivery with the interior finishes not applied, the joinery specified at an economy level, or only the main structure included. Add the missing items on top of that figure and the total usually climbs to the level of turnkey quotes — and can even overshoot it, because the work proceeds without a plan.

To bring quotes onto the same footing, ask these five questions: (1) Is the price turnkey or shell only? (2) Is the floor area gross or net — are the terrace and eaves included in the measurement? (3) How thick is the thermal insulation, and in which layers of the building is it applied? (4) Are the kitchen, bathroom, internal doors and floor coverings included in the price? (5) When was the quote issued and how long does it remain valid? With these five answers clear, you can genuinely compare the 100 m² prices of two different companies.

Factor in the long-term cost of a low price too: inadequate insulation comes back as a heating bill every winter, and economy-grade joinery as lost comfort and maintenance expense. A 100 m² family home will be used for decades, so the right unit of comparison is not “the lowest price today” but “total lifetime cost”.

The sound way to compare homes of different sizes is to divide the total price by the floor area. For the 100 m² Villa Yuva the arithmetic is clear: divide 2.249.000 TL by 100 and you get roughly 22.500 TL per square metre — and this is a unit price at turnkey level. For comparison: the unit cost is roughly 20.800 TL/m² in the 48 m² Villa İz and roughly 23.200 TL/m² in the 86 m² Villa Vadi.

The reason for these differences is the content of the plan. As a 1+1, Villa İz has few partition walls, doors and service points, which lowers its unit cost; in 3+1 plans such as Vadi and Yuva, the cost-generating details multiply along with the rooms. On the other hand, fixed items such as production and installation organisation thin out within the total at larger sizes, so at 100 m² the unit price eases slightly instead of rising above the 86 m² level. In short, the m² price is not linear; it forms in the balance between plan density and economies of scale — and 100 m² is one of the bands where that balance works most efficiently for family homes.

Two checks are essential when comparing this unit price with quotes on the market: the delivery scope behind the price, and how the floor area is measured. Comparing a shell-only price with a turnkey m² price, or placing a figure divided by gross area including the terrace next to one based on net area, can turn a quote that looks cheap on paper into an expensive one in reality.

For 100 m² prefab home prices, the clear reference for 2026 is this: at ifHaus, the 100 m² 3+1 two-storey Villa Yuva starts at 2.249.000 TL turnkey, which works out at roughly 22.500 TL/m². As you weigh the lower or higher figures you will see on the market against this reference, hold one question constant: a home of what scope is this the price of?

The sequence for a sound decision is equally clear: first learn the zoning status and dimensions of your plot; make the single-storey or two-storey decision together with the parcel conditions; request the turnkey scope list in writing; and have the plot items — foundations, transport, infrastructure — added alongside the home price so you can see your total budget. For anyone who follows these four steps, a 100 m² home budget becomes a plan rather than a guess.

You can explore the plans of Villa Yuva and all the other models on the /modeller page, and share your plot location and needs via /iletisim to request a tailored quote with a clearly defined scope. In a 100 m² family home that will be lived in for many years, the two most valuable things are a budget without surprises and a well-arranged plan.
