Serial apartment-building construction for municipalities: multi-storey residential, infill development and neighbourhoods at a glance — Project types in serial residential construction – multi-storey residential, infill development and neighbourhoods, without ranking.

Short answer

What the platform provides for municipalities and housing companies

The platform refers commercial-build-capable prefab and modular manufacturers for multi-storey residential construction, free of charge and discreetly. Municipalities, municipal housing companies and cooperatives describe their project profile and receive matching provider profiles in return. Projects from three to over twenty residential units, storey additions, infill developments and neighbourhoods can be realised. For public contracting authorities, the enquiry serves for market exploration and does not replace a procurement procedure. All apartment-building models are calculated project-specifically and are therefore listed with price on request.

Which project types can be realised in prefab and modular construction

Multi-storey residential construction with three to over twenty residential units can be implemented in serial timber construction or as modular construction. Smaller projects with three to eight residential units are covered by Haas Fertigbau, SchwörerHaus and WeberHaus with timber-panel construction. For serial residential buildings and neighbourhoods with a higher number of residential units, GROPYUS is geared to industrial prefabrication. The order of the providers is alphabetical and does not represent a ranking.

Storey additions and infill developments within the existing stock are a domain of modular construction. Containerwerk produces stackable room modules in series, which are suitable for storey additions and building gaps. Neighbourhoods with several building volumes benefit from prefabrication, because comparable buildings can be erected with predictable quality and shortened construction time. The specific feasibility depends on the plot, building law and the unit mix, and is checked project-specifically. Getting started is easy via the apartment building overview.

Process in five steps

From the project enquiry to the offer comparison in five steps. For public contracting authorities: the enquiry serves for market exploration and does not replace a procurement procedure.

Capture the project profile

Location, plot, desired residential units and target group are outlined in the free project enquiry. The more precise the profile, the more accurate the provider selection.

Identify matching manufacturers

Based on project type and size, commercial-build-capable prefab and modular manufacturers from the database are assigned. The selection is made objectively by service profile, alphabetically and without ranking.

Market exploration, not a procurement procedure

For public contracting authorities, procurement law applies. The enquiry serves for market exploration and does not replace a formal procedure. The municipality checks the procedural classification with its procurement office.

Response and call-back

A first response follows within 24 to 48 hours. Anyone who provides a phone number in the form can discuss the project by telephone and coordinate the provider selection.

Compare offers

The selected manufacturers get in touch with service profiles and an initial assessment. For apartment buildings, prices are calculated project-specifically and therefore quoted on request.

Procurement-law classification by the municipality and its procurement office on their own responsibility. The platform does not replace a formal procedure. As of 2026.

Serial construction for recurring building types

Serial and modular construction is aimed at standardised, recurring building types. Thanks to the high level of prefabrication in the factory, the construction time on site is shortened, and the quality remains comparable across several buildings. This creates predictable processes for housing companies with a larger construction volume. A strategic, multi-stage procurement approach, for example via framework agreements, can fit with this. The procurement-law design lies with the respective procurement office.

How serial construction works in detail, which building types are suitable and how the planning can be structured is explored in depth in the guide serial residential construction. Fundamentals on the house type and floor plans are offered by the pages on the apartment building as a prefab house and the apartment building floor plans.

Costs and funding as a guide

The following values are general market guides, not offers. Specific costs result from the project, the unit mix and the fittings.

Metric	Guide / range	Note
New-build apartment building (construction costs)	roughly €2,400 – 3,800/m² living space	Market range as a guide, not an offer
Prices of the apartment-building models in the database	Price on request	Project-specific calculation per project
Referral via the platform	free	Non-binding, no fees for the enquiry

Tax and funding conditions such as the declining-balance depreciation, Section 7b EStG or the KfW funding for climate-friendly new-builds can support residential construction in principle. The specific design and the conditions applicable at any given time change. Binding information is provided by tax advice or the KfW respectively. Yield considerations remain a simplified model calculation and do not constitute investment advice.

Municipalities & housing companies: frequently asked questions

Answers on market exploration and procurement, the costs of the referral, data use, and project sizes and process.

Does the enquiry via the platform replace a procurement procedure?

No. For public contracting authorities, procurement law applies, which prescribes its own procedures depending on the contract value. The enquiry via the platform does not replace a formal procurement procedure but serves for market exploration. It helps to get to know commercial-build-capable prefab manufacturers and their service profiles before a procedure is set up. Municipalities and municipal housing companies check the specific procedural classification on their own responsibility, usually together with the procurement office or the legal department.

What does the referral via the platform cost?

The referral is free and non-binding for municipalities and housing companies. There are no fees for the project enquiry or the compilation of matching provider profiles. An enquiry creates no obligation to accept an offer or to initiate a procedure. The platform is financed through the referred manufacturers, not through the enquiring public or non-profit contracting authorities.

How is the transmitted data used?

The information from the project enquiry is used solely to identify matching commercial-build-capable manufacturers and to forward the enquiry to selected providers. It is passed on in a targeted way to the companies matching the project profile, not unfiltered to the entire market. Processing follows the details in the privacy policy. On request, the number of contacted providers can be limited.

Which project sizes can be realised in prefab and modular construction?

Multi-storey residential buildings from three to over twenty residential units, additions of storeys and infill development within the existing stock, and coherent neighbourhoods can be realised. Smaller projects with three to eight residential units are covered, for example, by Haas Fertigbau, SchwörerHaus and WeberHaus. Serial neighbourhoods and larger series are planned by GROPYUS. Storey additions and infill development are a domain of modular construction, for example at Containerwerk. The specific feasibility depends on the plot, building law and the unit mix.

How quickly is there a response after the enquiry?

After submitting the project enquiry, a first response usually follows within 24 to 48 hours. Anyone who leaves a phone number in the form can receive a call-back to discuss the project profile and the matching providers directly. The timeframe is a guide value and may differ for complex projects or during holiday periods. For urgent projects, the desired timeframe can be noted in the enquiry.

Is serial construction suitable for framework agreements?

Serial and modular construction is designed for recurring, standardised building types and therefore fits well with a strategic, multi-stage procurement approach. Housing companies with a larger construction volume use this to build comparable buildings efficiently and with predictable quality. The procurement-law design of framework agreements lies with the respective procurement office. The platform supports the upstream market exploration and classifies the manufacturers' service profiles.
