Quality building and installation

Once your project design has been finalised, we manufacture the approved design off-site in our facility in order to deliver as close to a finished product as possible. We have designed a system requiring minimal on-site work, thus ensuring a fast and hassle-free build. The installation takes from 1 day to 10 days for the most complex construction.

Professional service from start to finish

Follow our simple steps and we will help guide you through the entire process. Once you decide to team up with us on a project, we will assign a project coordinator from start to finish. This person will be a direct point of contact for you throughout the entire process, having full knowledge of your build.


The beginning of the project consists in identifying your needs, your wishes, and the possibilities that your house and site offer.

After the initial consultation, the first designs will be drafted, in order to define the concept that suits your request.

Finally, you will decide which design suits your requirements and detailed drawings are produced.


Once the concept is chosen, we order all the quality material needed to manufacture your project in our workshop.

We will make the building available to be viewed once completed in our factory prior to delivery to site. This is to ensure you are happy with the product and that in the unlikely event that there were to be variations, these can be considered prior to site delivery.


The installation of the build will be really fast. Our crew will arrive to do all site preparation in advance. This may include the removal of existing paths to rear of house, re-routing of drainage and opening up the back of the house (for extension). There will be a crane on site for one day. First of all, solid precast concrete foundations will be set, then the extension/rooms will be lifted into position. If we are not off site within ten days we will pay you rent for every additional day we spend on site*.


We provide a variety of services related to modular houses and extensions.

If you are thinking about modular bathrooms, modular houses, modular kitchens or modular extensions then passivebuild is the place to visit.
