A1 Customisation expands your horizon

How nice it is to have an extra living space in the living room or kitchen, or an extra room for your hobby. We create more space for you according to your wishes and needs.

Tip

An extension, what is allowed and what is not? Before you decide, talk to a member of the local council office near you. They will provide you with free information on what you can or cannot build on your land.

Task for us

Extensions, sheds, storage solutions and more

Do you prefer a beautiful stone wall or perhaps a transparent glass structure? We are happy to think along with you and advise you on the possibilities when it comes to an extension, a shed, a smart storage solution and more. You make the choice and we take care of the entire process. From pouring concrete to installing window frames and roofs. But also the interior finishing such as plastering, flooring, electrical work, and if necessary, pile driving of the foundation.


We realise various extensions, such as:

  • conservatories

  • verandas

  • bays

  • sheds

  • storage solutions

  • extensions in the back or side garden

  • rooftop terraces

  • roof extensions

  • dormers
