Duna — timber-frame houses
Калининградская область
The site answers “how much is it and will the estimate double” before any form: price on the first screen, a calculator that prices a specific house.

Challenge
The main pain in this niche is “how much is it and will the estimate double”. While both questions hang unanswered, hardly anyone gets as far as a call.
Solution
The price sits on the first screen and the calculator prices a specific house. The “fixed price, no hidden extras” and “5-year warranty” blocks close the main fear before the call. There are projects, mortgage info, a blog and a questions section.
Result
The request arrives with the sum already calculated — the conversation starts from a specific house, not from scratch.


Other cases

inestroy — house construction
A construction company site where the request reaches the manager with the house parameters already in it, not a blank “call me back”.

Architecture studio
A premium presentation: the site is built around the work — a full-screen project slider, a calm dark theme, not one promo banner.

AVANTLY — renovation and finishing
The estimate is worked out on the site, not over the phone: three tiers with scope of work and an online calculation by area.
