Building services design for a house in Batumi: water, heat, ventilation, electrics
The building services design for a house decides in advance where pipes, ducts and cables will run, how much water, heat and electricity the house needs and how it connects to the city networks. We design water supply and drainage, heating, ventilation with fresh air for a humid climate, electrics with load calculations, gas and stormwater. All systems are coordinated with the architecture before the first pour. Services design from 30 ₾ per m².

Building services design for a house: networks on paper before construction
The building services design for a house decides in advance where pipes, ducts and cables will run, how much water, heat and electricity the house needs, and how it all connects to the city networks. If the services are not drawn in advance, the crew lays them however suits it: a riser goes through a future wardrobe, the extract duct does not fit in the ceiling, the consumer unit hangs in full view in the hallway. Fixing this after the finishes is expensive. In the design all systems are coordinated with the architecture and structure before the first pour.
Which sections are included
| Section | What we decide |
|---|---|
| Water supply and drainage | Water entry, risers, distribution, falls, outfall, a septic tank if needed |
| Heating | Heat source, underfloor heating or radiators, output calculation |
| Ventilation and air conditioning | Supply and extract in every room, outdoor units |
| Electrics | Load calculations, consumer unit, circuits, sockets, lighting, earthing |
| Gas | Entry, route, boiler and hob to the gas company's requirements |
| Stormwater and drainage | Draining water from the roof and the plot |
How these systems are then installed is described on the utilities page.
Ventilation in a humid climate
- fresh air supply to every living room;
- extract from bathrooms, the kitchen and walk-in wardrobes;
- dehumidifying the basement and closed rooms;
- space for air conditioner outdoor units;
- airing a house that stands closed.
In Batumi ventilation matters more than in many other places: humidity rarely drops below 70 %, and an airtight house without fresh air supply soon gets covered in condensation and mould. System options are on the ventilation page.
Heating and the heat source
Winter by the sea is mild but damp, and a house without heating is uncomfortable in January. In the design we choose the heat source: a gas boiler, a heat pump or air conditioners, calculate heat losses and output, and decide where to use underfloor heating and where radiators. More about the systems on the heating page.
Electrics and connections
The load calculation shows how much capacity to request from Energo-Pro Georgia, and it determines cable sizes, breakers and the consumer unit. In the design we lay out circuits, sockets and lighting room by room, and provide earthing, surge protection and spare capacity for the future: car charging, a pool, solar panels. How a house is connected to the grid is on the power supply page. Water is connected on Batumis Tskali's terms, gas to SOCAR Georgia Gas's requirements.
Water from the roof and the plot
Batumi gets over 2 400 mm of rain a year, and stormwater has to be designed together with the house. The water utility does not allow rainwater to be discharged into the foul sewer, so we plan gutters, rain inlets, drainage around the foundation and water removal beyond the plot. More on the drainage and stormwater page.
How much building services design costs
All building services sections of a house design cost from 30 ₾ per m². An electrical design with load calculations and a consumer unit diagram from 1 260 ₾, a heating, ventilation and air conditioning design from 1 680 ₾, a water supply and drainage design from 1 080 ₾. A gas supply design with connection support from 1 080 ₾, a fire alarm design for a guesthouse or mini-hotel from 1 800 ₾, a site survey with a drainage and stormwater design from 1 200 ₾. The final cost is set after reviewing the architecture and agreeing which sections are needed.

Local specifics in Batumi
Batumi's climate sets its own conditions for building services. Humidity is rarely below 70 %, the summer dew point can exceed +20 °C, and without fresh air supply and dehumidification condensation and mould appear in the house. Winters are damp and windy, so the house needs heating even though there is hardly any frost. Many houses stand closed for months, and for them we design airing and humidity control that work without the owner.
Connections to utilities in Adjara follow the terms of three companies: water from Batumis Tskali, electricity from Energo-Pro Georgia, gas from SOCAR Georgia Gas. We obtain the terms before design starts, so that routes and capacity match what will actually be supplied to the plot.

What makes up the cost

Questions and answers
How much does building services design for a house cost?
All services sections cost from 30 ₾ per m²; separately, electrics from 1 260 ₾, heating, ventilation and air conditioning from 1 680 ₾, water and drainage from 1 080 ₾. The final cost is set after reviewing the architecture and agreeing which sections are needed.
Can you do without a services design?
In a small house an experienced crew will manage without one, but then the services go wherever suits the crew. In a bigger house without a design the risers get tangled, ducts do not fit in the ceiling and there is not enough capacity. A services design costs less than a single rework after the finishes.
Which heating should I choose in Batumi?
It depends on the house and how you live in it. A gas boiler with underfloor heating suits permanent living, a heat pump is economical to run but costs more upfront, and air conditioners suit a house rarely used in winter. In the design we calculate heat losses and compare the options for your scenario.
Why ventilation if you can open a window?
In a humid climate an open window brings even more moisture into the house, and cold in winter. Filtered supply air and extract from bathrooms and the kitchen keep humidity under control without draughts. This matters especially for a house that stands closed: without ventilation it smells of damp by the time the owner arrives.
Who obtains the utility connection terms?
We can obtain them under a power of attorney or help you submit the applications. Terms from Batumis Tskali, Energo-Pro Georgia and SOCAR Georgia Gas are needed before design: routes, capacity and the entry point depend on them. Each company takes a different time to respond, so we apply as early as possible.
