Draw your house plan like in Excel —
see the m², the price and the house in 3D
Pick a room and drag a box over the squares, the way you select cells in Excel. Every box is a room; the areas add up by themselves. Then see your wooden house in 3D or ask manufacturers for a price. Free.
Wooden houses only
The easiest way to draw a house plan
You don't need to know architecture software. If you can select cells in Excel, you can draw your house here: pick a room and drag a box. Each square is 0.5 m (or 1 m) and a darker line marks every metre, so you see the size while you drag. Draw the living room, bedrooms, kitchen, bathroom, hall, a sauna and the terrace. Every box is a room with walls all round. The eraser removes squares or, with one click, a whole room; × in the list does the same.
The list next to the grid shows every room's area, the inside area and the terrace. That inside area is what wooden house manufacturers price, so you can see right away whether the plan fits your budget.
Already drew it in Excel? Open the file
Press Open Excel / CSV and choose your .xlsx file. Each coloured area becomes a room; a word you typed in one of its cells names it — in English or your own language (Bedroom, Yatak odası, Schlafzimmer, Makuuhuone…). A CSV file can also hold one letter per square:
| Letter | Room |
|---|---|
| L (or L2 for a second one) | Living room |
| B (or B2 for a second one) | Bedroom |
| K (or K2 for a second one) | Kitchen |
| W (or W2 for a second one) | Bathroom / WC |
| H (or H2 for a second one) | Hall |
| S (or S2 for a second one) | Sauna |
| U (or U2 for a second one) | Utility / storage |
| R (or R2 for a second one) | Other room |
| T (or T2 for a second one) | Terrace (outside) |
Download for Excel saves your plan as such a file, to change it in Excel and open it here again.
From your plan to a manufacturer's price
- Estimated price — choose your country: inside area × the turnkey price per m² for a standard wooden house there, from public price guides (Sept 2026), without land, site works and permits.
- Get prices from manufacturers — your plan (as a picture with the room areas) goes to wooden house manufacturers that deliver to your country. They contact you with their price. Free, no obligation.
- See it in 3D — the free 3D editor builds the walls from your squares. Add doors, windows and the roof, choose log, timber frame or CLT walls and walk through your house.
Questions
Can I draw a floor plan in Excel?
Yes — many people do: make the columns narrow so the cells are squares, decide what one square is (for example 0.5 m), and colour the cells of each room. You can draw it on this page instead, where the squares already are 0.5 m or 1 m, the room areas add up by themselves and the plan opens in 3D. If you already have an Excel plan, open the .xlsx file here: coloured areas become rooms and a word in a cell (Bedroom, Kitchen, Yatak odası, Küche…) names the room.
How do I get a price for my house plan?
Draw the rooms, choose your country and you see an estimated range for a turnkey wooden house from public price guides. For a real price, press "Get prices from manufacturers": your plan goes to wooden house manufacturers that deliver to your country, who contact you with their price. It is free and you are not obliged to buy.
How accurate is the estimated price?
It is the inside area times an indicative turnkey price per m² for a standard timber-frame wooden house in your country, from public market guides (September 2026), without land, site works, connections and permits. It shows the order of magnitude. For countries without a reliable source we show no number and you can ask manufacturers instead.
Can I see my grid plan in 3D?
Yes. "See it in 3D" turns the coloured squares into walls (round the outside and between rooms), floors, a terrace and named rooms in the free Geoniks 3D editor. There you add doors, windows and the roof, walk through the house and change any wall to log, timber frame or CLT.
I have a sketch on paper or a PDF plan, not Excel.
Send it as it is: the "My 2D plan → 3D" form takes a phone photo of an A4 sketch, a PDF or an Excel file. The Geoniks team draws it as a 3D wooden house and manufacturers send their prices.
Is it only for wooden houses?
Geoniks works with wooden houses only — log, timber frame and CLT homes, cabins and villas. We can’t help with concrete, steel, apartment or office buildings.
