Basements built since 1980




How flexible are prefabricated basements?

Prefabricated basements are created using the same principle as prefabricated houses: the individual elements are prefabricated (pre-made) in a factory environment, delivered to your plot and assembled by our team of trained professionals, with precision and quality. A huge advantage is that you can create a basement that is completely unique and designed to meet your exact needs. Do you dream of having a living basement - one that can be used as a spare bedroom, games room or living area - or a utility space to keep appliances tucked out of view? We can work with you to create exactly what you want.

Which documents are required?

Requesting a Quote: First things first, we require a plan of your basement, a floor plan of the ground floor, the storey height and the details of your home manufacturer to prepare a quote. If you have any other documents or details, please let us know so we can prepare the most comprehensive quote for you.

The Construction Process: We will need to see your submitted building application, which contains, among other things, the floor plan, the drainage plans, building permit, soil survey and a report on the house statics. Where possible, confirmation of the financing, soil survey, basement plan and ceiling opening plan should be included.

What are the advantages of a prefabricated basement?

There are numerous benefits to a prefabricated basement. Here are our top 5:

1) For only 5% addition to the total costs of building a house, a basement can be created as a comfortable and vibrant living space which will add considerable value to a property.

2) Prefabricated basements come with a fixed contract price

3) Basements are prefabricated (pre-made) under controlled conditions with pinpoint accuracy

4) Prefabricated basements come with guaranteed completion dates

5) Prefabricated basements benefit from a short onsite construction time

What do I need to take into account when building a basement?

All decisions should be discussed in advance with the glatthaar project manager. Errors in the ground assessment, sealing concept, or the construction can be expensive but easily avoided with proper planning and consideration.

How long does it take to install a basement?

The construction of a prefabricated basement usually takes between 3 & 5 weeks, depending on the particular development and size of the basement chosen.

Is there any work I can do?

All services connected with the static construction and sealing of a basement structure must be carried out by our glatthaar specialists. Cosmetic finishes including interior painting can be carried out by owners or third-party contractors. 

What materials make up a prefabricated basements?

Prefabricated basements are made of impermeable concrete and offer the best protection against penetrating moisture. As they are premanufactured in a state-of-the-art factory, they have a small number of joints which further reduces the risk of damp and ensures they are built to perfect dimensions.

How closely do you work with house manufacturers?

We work very closely with the majority of the prefabricated house providers. We have formed strong relationships with these suppliers over the decades, reducing the risk of planning errors and ensuring projects run efficiently.

Which countries do you work in?

Glatthaar operates within Germany, United Kingdom, Ireland, Switzerland, Austria and Benelux countries.

What is glatthaar's construction process?

Step 1: Create working drawings and structural calculation

Step 2: Individual wall and ceiling panels are prefabricated in the factory

Step 3: All required openings for windows, doors, stairs or servive supplies are installed

Step 4: The prefabricated basement wall and ceiling panels are transported to the construction site

Step 5: The various components are set in place using cranes on the prepared foundation

Step 6: The wall and ceiling panels are fixed and filled with concrete

Are uninsulated basements still useful?

What's the point of having a cold, unusable space? A basement should be integrated into your overall house and not drain heat and energy. High-quality insulation reduces the risk of damp, condensation and general moisture-related issues and retains heat, creating a clean, healthy environment.  So, are uninsulated basements still useful? In a word, no. 

Should basements be completely insulated?

This depends on what you intend to use your basement for. If you intend to build a 'cold basement' (one without heating), then you will need to take care to ensure that the open inner basement exit is completely insulated. If this is not considered, then energy losses and, in extreme cases, structural damage can occur. To avoid condensation however, we would always recommend that you insulate the entire basement so it is free of thermal bridges.

Is adding insulation after construction a possibility?

It is, but it is relatively expensive. Ideally, proper insulation should be carried out during the construction phase in order to save time, money and stress.

Can basements be individually tailored to specific requirements?

Each and every one of our basements is individually tailored to meet your wishes. The industrial production does not limit our ability to build bespoke products. Instead, it ensures your specific requirements are precisely manufactured to pinpoint specifications and ready to be installed on site.
