Five trades, one point of contact — from karst soil to grid connection.
Adria EcoTech & Real Estate guides investors, owners, farmers and municipalities from the first site question to final handover: photovoltaics and storage, scale-resistant water technology, forest conversion and soil recultivation, property purchase with land register checks and a network of lawyers, energy retrofits.
End-to-end project development in Croatia: from renewable energy and innovative water technology through legally sound real estate services to forest conversion, karst soil recultivation and EU funding.

Five pillars that belong together in practice
A plot in Dalmatia rarely needs just one trade. Buyers need a checked file and legal certainty. Builders need power, water and ground that carries. So the pillars can be booked separately but are planned together — and every summary starts by naming who it is for.
Renewable Energy & Off-Grid
Design, installation and operation of PV and battery storage systems — grid-synchronous or fully off-grid. Control systems are built in-house in our own switchgear workshop.

Most projects touch several pillars at once — a plot needs a file review, water and power. Describe the project and we will sort the trades.
Start an enquiryOne rock explains three pillars
Dalmatia sits on limestone. That single geological fact produces three problems that look unrelated at first glance — and share one cause.
- Hard waterRainfall seeps through the fissures and dissolves calcium and magnesium. The result is hardness above 12 °dH, which destroys conventional heating elements within a few years.
- Thin soilAbove the rock there are often only five to thirty centimetres of humus. Without milling and deliberate humus build-up the land carries neither agriculture nor a building.
- Fire loadDry pine monocultures on shallow karst burn fast and hot. Converting them into fire-resistant mixed forest is fire protection, not landscaping.
Four audiences, one requirement
Four groups with very different questions — and the same requirement: reliable figures, clear responsibility, a permitting position you can follow.
Investors & business
Site assessment, yield forecasts, grid and permitting position, viability across the full project lifetime.
Private owners & buyers
Purchase support with file review and a network of lawyers, refurbishment planning, off-grid supply for remote properties.
Farmers & forestry
Karst soil recultivation, humus build-up, forest conversion and eligibility under the EAFRD.
Municipalities & counties
Preventive fire protection through forest conversion, municipal water and waste water solutions, EU-compliant application files.
What it comes to in the end
One example from an existing building: a house before and after the work. All projects — from the new build in Dalmatia to the retaining wall — are on the reference page.


How a project works with us
Four steps, in this order. Costs beyond an advisory fee only arise after step two.
- Step 01
First conversation
You describe the project, the land and the timeframe. We say plainly which pillars are involved — and which are not.
- Step 02
Site & legal review
Land register, cadastral position, grid connection, water hardness, soil profile. The result is a written finding with a cost range.
- Step 03
Design & funding application
Technical design, comparison of quotes, permitting documents and — where relevant — the funding application.
- Step 04
Delivery & handover
Coordination of local trades, site supervision, commissioning, documentation and handover.

One sentence about the project and the cadastral parcel is enough for a first assessment. We normally reply within two working days, in German, English or Croatian.
