Warm or cold winter garden — or greenhouse
A warm winter garden is heated and usable year-round, a cold winter garden extends the season from spring to autumn, and a greenhouse is for plants. We choose the solution for your use during planning.

Why a winter garden
A room where the year does not end in autumn
A winter garden extends the home into light — a cosy, practical room to your house or yard, usable even when it is cold and dark outside.
We offer winter garden and greenhouse construction for detached houses and commercial buildings. We build durable, weather-resistant solutions suited to the Estonian climate — using timber and glass for longevity. Other materials can be used if needed.
- Design and planningWe help design a winter garden or greenhouse to your wishes — choosing the right size, style and materials.
- Winter garden and greenhouse constructionWe build to plan using quality materials for long-term durability.
- Maintenance and repairIf you already have a winter garden or greenhouse, we offer maintenance and repair if needed.
What to consider
Three things that distinguish a good winter garden from a cheap one
The whole difference lies behind the glass: whether the room stays cosy year-round or collects condensation and cold. We review these before building.
Glass quality
Double or triple glazing (Ug ≤ 1.1 W/m²K) keeps warmth in and prevents condensation. The right glass determines how comfortable the room actually is in winter.
Built for the Estonian climate
A winter garden must withstand snow load and condensation in Estonian winters. The foundation is built 80 cm below the frost line and roof pitch at least 15° so snow slides off.
Winter garden vs greenhouse
Which solution suits your plot?
Use determines how much glass, insulation and material is needed. Below, honestly and without sales talk — finer choices are agreed at measurement.
| Solution | Use | Glazing | Year-round use |
|---|---|---|---|
| Warm winter garden | Heated living space — dining room, lounge, office. | Triple glazing (Ug ≤ 1.1) | Year-round |
| Cold winter garden | Season extension — spring to autumn, unheated. | Double or triple glazing | Spring–autumn |
| Greenhouse | For plants — a light-filled growing room in the garden or yard. | Glass or a suitable alternative | Growing season |
We mainly use timber and glass for durability and longevity. Other materials such as aluminium frames can be used if needed.
Structure and materials
Timber and glass that last
We use timber and glass for durability and longevity. A timber frame is warm and natural, glazing brings light indoors and keeps warmth in — together they form a strong, cosy whole.
We build to plan from quality materials so the winter garden or greenhouse lasts for years. Other materials can be used if needed.
- Load-bearing timber frame designed for snow load
- Double or triple glazing (Ug ≤ 1.1 W/m²K)
- Other materials if needed, e.g. aluminium frame

Kuidas me ehitame
Winter garden construction in six steps
We build step by step — each stage requires the previous one to be ready. That way the structure withstands Estonian winters and glass stays condensation-free.
1
Design and planning
We visit and discuss use — warm winter garden, cold winter garden or greenhouse. We choose the right size, style and materials to your wishes.
2
Foundation
We install concrete pads or timber posts 80 cm below the frost line so the winter garden does not subside during frost heave. Clay Harjumaa soil needs a proper base.
3
Load-bearing timber frame
We build a load-bearing timber frame to plan, accounting for snow load and future glazing. The frame is the backbone of the winter garden.
4
Glazing
We install double or triple glazing (Ug ≤ 1.1 W/m²K). The right glass brings light indoors, keeps warmth in and prevents condensation.
5
Roof and pitch
We build the roof at least 15° pitch so snow slides off in Estonian winters and does not load the structure.
6
Finishing and handover
We finish details, walk through the work with you and advise on maintenance. We offer maintenance and repair later if needed.
“We help create a cosy, practical room for your home or yard — a winter garden where light continues even when it is dark outside.

Technical requirements
Winter garden and greenhouse construction requirements in Harjumaa
A winter garden must withstand snow load and condensation in Estonian winters. These are the requirements we follow on every project in Tallinn and Harjumaa so the room stays warm and dry.
- Foundation — concrete pads or timber posts 80 cm below frost line
- Double or triple glazing (Ug ≤ 1.1 W/m²K)
- Roof pitch at least 15° for snow to slide off
Most important in a winter garden
Condensation and frost heave are a winter garden's main enemies. A foundation below the frost line and correct glazing keep the room dry and warm for years — the difference often missing in cheap solutions.
Foundation and frost line
The winter garden foundation is built as concrete pads or timber posts 80 cm below the frost line. That way frost does not lift the structure or crack the glass.
Glazing and thermal performance
We use double or triple glazing with Ug ≤ 1.1 W/m²K. A warm winter garden needs triple glazing; a cold winter garden or greenhouse can use double.
Roof pitch and snow load
The roof is built at least 15° pitch so snow slides off and does not load the structure. The load-bearing timber frame is designed for Estonian snow load.
Condensation and ventilation
A winter garden must handle condensation. Correct glazing, a warm frame and thoughtful ventilation keep glass dry and the room cosy in winter too.
Materials
We mainly use timber and glass for durability and longevity. Other materials such as aluminium frames can be used if needed.
Price and payment
What affects winter garden price
Winter garden or greenhouse cost depends mainly on size, chosen solution and materials. Glazing type and heating also affect the final price. Exact price is confirmed after free measurement and agreeing details.
- Size, style and intended use
- Warm winter garden, cold winter garden or greenhouse
- Glazing type (double or triple)
- Foundation and materials (timber, glass, aluminium)

FAQ
Frequently asked questions
What is the difference between a winter garden and a greenhouse?
A winter garden extends the home for people — warm (heated, year-round) or cold (unheated, spring to autumn). A greenhouse is for plants. We help you choose the right solution during planning.
How deep is a winter garden foundation built?
Foundation — concrete pads or timber posts — is built 80 cm below the frost line so frost heave does not lift the structure.
What glass is used in a winter garden?
We use double or triple glazing with thermal transmittance Ug ≤ 1.1 W/m²K. This keeps warmth in and prevents condensation.
What pitch must a winter garden roof have?
Roof pitch is at least 15° so snow slides off in Estonian winter and does not load the structure.
What materials is a winter garden built from?
We mainly use timber and glass for durability and longevity. Other materials such as aluminium frames can be used if needed.
Do you also maintain existing winter gardens?
Yes. If you already have a winter garden or greenhouse, we offer maintenance and repair if needed. Contact us to discuss.
