Building a house starts with one question: "Can we afford it?"

At Colchis Lab, we build the construction calculator into your website as part of the design — your colors, your logo, your prices. It handles the parameters that actually decide what a private house costs:

• Area and floors — the base of the whole estimate
• Roof type — flat or pitched, each with its own pricing
• Frame stage — how far you take the build, from foundation to a finished frame
• Basement — length, width and depth, priced as excavation and concrete work really cost
• Pool — dimensions entered by the visitor, added to the estimate instantly
• Fence — along the plot perimeter

The visitor plays with these options and watches the total change in real time. That “what if” moment — what if we skip the basement? what if we add a floor? — is exactly what keeps people on your site instead of a competitor’s.

Alongside the total, the calculator shows the price per m², an approximate duration and where the money goes, stage by stage. Every result is clearly labeled as an estimate, confirmed after the design and a site visit.

You can try the working demo on our construction calculator page.

No two builders price a house the same way. Your concrete supplier, your crews, your margin — they are all different from the company across town. A calculator with “average market prices” would quote jobs you can’t actually build, and lose the client’s trust at the first real conversation.

So we set the calculator up together with you:

1. You hand us your rates — price per m² by frame stage, roof pricing, excavation and concrete costs for basements, your margin. Type them into our demo or send a spreadsheet.
2. We agree on the logic — how floors multiply the cost, what a pitched roof adds, how you price the extras.
3. We test it on your past builds — before launch, we run finished houses through the calculator and tune it until its numbers match what you really charged.

Your pricing stays yours. The formula runs on the server, never in the page code, so competitors can’t open your site and copy your rates or margin. When prices change, we update the numbers and the site stays the same.

The calculator does the convincing, but the website does the finding. Every site we build comes ready for Google from day one: full SEO setup with structured data and a sitemap, Google Search Console and Analytics connected, Google Tag Manager for tracking, optional Facebook Pixel for ads, accessibility for screen readers, and fast, fully responsive pages.

Your site also gets a projects section — each finished house with photos, area, timeline and the frame stage you delivered — and a blog that answers what your clients actually search for: how long a two-storey house takes to build, flat or pitched roof, what a green frame includes. Google brings the reader, the article warms them up, the calculator turns them into a caller.

Renovation is your market too? The same site can carry both tools — we covered the renovation side in our renovation cost calculator article.

House construction is local. Foundations are priced differently where the ground freezes, roof norms change with the climate, and the stages of a build — even their names — differ from country to country. A calculator built by developers alone would miss all of it.

That’s why a hired renovation and construction expert works alongside our developers on every calculator. Before we write the formula for your market, the expert works through your details with you: the materials and frame standards your clients expect, the order your crews actually build in, whether you price per m² or per stage, and the local terminology — so the calculator sounds like a builder wrote it, not a programmer.

The result: estimates your clients recognize as realistic, in your currency and your units, wherever you build.

1. Send us your prices. Enter them in the demo on our proposal page, or send a spreadsheet — the “Send us my prices” button even writes the WhatsApp message for you.
2. We build the site. Your colors, your logo, the construction calculator set up on your rates and checked against your past builds.
3. You get a finished site. Visitors budget their own house, and the calls you take start from a real number.

Already have a website you like? The construction calculator can be added to it on its own — no rebuild needed. Or take the full package with the renovation calculator included, so one site covers both services. Domain and hosting are paid to your provider separately.
