In short

This guide organises the steps from wanting a balcony to implementation: configuration and price, kit or installation, structural design and permit, as well as flooring and drainage. It is general orientation and does not replace project-specific professional planning.

Costs and specification

Width, depth, storeys, flooring and railing determine your selection. Calculate the configuration online; check delivery, installation and other services separately in the quotation.

Kit and self-assembly

A made-to-measure add-on balcony kit is delivered according to the agreed configuration. Clarify components, fixings and assembly documents. Technical skills, crew and lifting equipment must suit the structure.

Preparing installation

First, survey, foundations and site access are checked. Work then follows the assembly documents: structure, railing, floor build-up and water drainage. Finally, the execution is inspected. Alternatively, installation is arranged through partner companies.

Structural design and permit

Before adding a balcony to a building, clarify verifications and permit requirements with professional planners and the building authority. Support with structural design and building permit is optional.

Flooring and drainage

A waterproof balcony floor needs a complete system build-up. With the NOVODACH WPC rail system, boards, rails, connections and drain are planned together.

Frequently asked questions

How much does an add-on balcony cost?

The price depends on dimensions, storeys, flooring, railing and specification. Calculate your selection in the 3D configurator and check delivery, VAT and additional services in the stated scope of supply.

Do I need a building permit?

Whether a permit is required, and which one, is clarified for the location and the project. Agree the documents with your planning and the responsible building authority; support with the permit application is optional.

Can I assemble the add-on balcony myself?

Self-assembly is possible once the structure and prerequisites have been agreed. It requires technical skills, suitable lifting equipment, prepared foundations and the assembly documents. Alternatively, installation is arranged through partner companies.

Is the balcony floor waterproof?

The intended system build-up is designed to drain water in a controlled way. WPC boards alone are not enough for this; correct planning and installation are decisive. Rails, connections and water drainage must be planned and installed to match.

How does the WPC rail system work?

The NOVODACH WPC rail system guides water through the intended floor build-up to the drain in a controlled way. Boards, rails and edge connections work together; the exact execution depends on your balcony.
