Build a conservatory with a glass roof? Better not! Tips and tricks for conservatory planning

More space, more light and more living comfort : The conservatory is a perfect way to extend the living space in a modern and comfortable way. Thanks to innovative materials and intelligent technologies, it is now possible to use the conservatory all year round. However, this requires meticulous and expert planning. It is important to avoid common mistakes - such as the conservatory roof made of glass - and above all, not at the wrong end to save. Read our guide to conservatory planning, so that you can really enjoy your extended living room after completion.

Choosing the Right Conservatory Type

In principle, there are three different ways to implement a conservatory:

  • Non-Heated Glass Appliqué
  • Lightly Heated Crop as a Wintering Site for Frost-Sensitive Plants
  • Heated Crop that Can Serve as Year-Round Living Home

What you choose is a matter of your personal preference and, of course, your budget , A conservatory that is heated year round will incur higher initial and operating costs than unheated glass.

If you want to create extra living space that can be used both summer and winter, a conservatory may not be right for you. Better would be a classic cultivation, which has a good thermal insulation and a solid roof. A heated conservatory made of glass is a waste of energy in winter.

It is also important that you choose a winter garden that fits in architecturally with your home. This usually does not apply to inexpensive, prefabricated models from the catalog. In the worst case, such a conservatory may even lower the value of your property.

Proper Conservatory Planning Is Essential

In any case, it is important that you plan your conservatory carefully before you begin construction. Think in advance how you want to use the conservatory, what size you need and how the extension should be ventilated. The snow load should also be calculated. The walk to the responsible building authority is indispensable. You may need a building permit.

In the worst case, if you save your way to the building office, it may happen that you have to demolish your finished conservatory.

In many federal states of Germany, the winter garden is subject to submission. This means that you submit all the construction documents and the building authority decides whether you need a permit for the construction and which conditions must be met in order for you to obtain the building permit.

Better not a glass roof on the winter garden

Many homeowners dream from a fully glazed conservatory and also want to build the roof of glass. But we advise against that. A closed roof is more suitable: in summer it serves as a sunscreen, while in winter it stores the heat much better than the variant made of glass. The heat radiation is enormous with a glass roof. For this reason, winter gardens that are to be used all year round should always be equipped with solid roofs.

Using high-quality materials

Since a winter garden is the link between interior and exterior, the demands placed on the materials used are high. Anyone saving here risks building damage. Normally, the following materials are used for the construction of a winter garden:

  • wood
  • plastic
  • aluminum

A mix of different materials is also conceivable. Which material you prefer depends primarily on the static requirements. But your financial resources also play a role in the choice of materials certainly. It is also important to use high quality glass. It should be able to prevent both extreme winter heat loss and solar overheating during the warm season.

Think of a suitable sunscreen

Many homeowners forget in their dream of a fully glazed conservatory, how hot it can be in the summer without appropriate shading. The temperature quickly rises to more than 35 degrees Celsius, so you can not stay in the conservatory anymore. An external sunscreen can help prevent this.

Awnings are great for sunshading the conservatory because they block out the sun's rays before they reach the glass front.

Automatic sun shading systems are also popular. They have temperature sensors that allow the awning to extend only when the room has a certain temperature. This saves you valuable heating energy in spring and autumn.


Many homeowners dream of a glazed winter garden on the living room as a wintering place for frost-sensitive plants or year-round extension of the living space. However, such a winter garden should always be well planned, so that the joy is not prematurely clouded. For example, a solid roof is better than a glass roof, and sun protection must also be used.
