Multi-storey residential building in modular construction

Respond quickly to the housing shortage

The demand for affordable, high-quality living space is constantly increasing, especially in growing cities. Traditional construction methods are increasingly reaching their limits: long construction times, rising costs and a lack of planning certainty are making it difficult to realise many residential construction projects.

ALHO is setting new standards with modular multi-storey residential construction. Thanks to industrial prefabrication under controlled conditions, sustainable, multi-storey residential buildings are created that are characterised by short construction times, predictable costs and resource-saving processes. And although modular construction is used, no two ALHO projects are the same: Each building is individually planned and architecturally realised in such a way that it blends harmoniously into its surroundings - functional, high-quality and with character.

70% shorter construction time and reliable scheduling thanks to weather-independent, serial production.

Planning and investment security thanks to a fixed price guarantee.

Clean and quiet construction sites thanks to a high degree of prefabrication.

Low life cycle costs thanks to integrated planning.

Sustainable construction through optimized use of resources.

Controlled quality through certified factory production.

High flexibility thanks to a self-supporting steel skeleton structure with non-load-bearing walls.

Appealing architecture thanks to individual cubature, floor plan, and facade design.

FAQ on multi-storey residential construction in modular design

In modular construction, buildings are constructed from prefabricated room modules that are produced in the factory under controlled conditions and then assembled on the construction site. In contrast to traditional construction methods, where many trades work on site one after the other, modular construction involves numerous processes running in parallel, such as module production and foundation work. This significantly shortens the construction time, reduces weather-related delays and ensures greater cost certainty and consistent quality.

The modular construction method is ideal for a wide range of residential construction projects, especially where living space needs to be created efficiently, cost-effectively and to a high standard. Typical areas of application include social housing, student residences, assisted living and private apartment blocks.

Modular multi-storey residential construction really comes into its own in inner-city locations or on cramped plots. Industrial prefabrication in the factory enables fast and precise realisation on site, reduces noise and traffic congestion and ensures reliable scheduling and budget planning.

However, modular construction is not suitable for projects such as extensions to detached houses, as the serial reproducibility of the modules is designed for larger, systematically planned buildings. Simple residential containers are also not an alternative as an extension. They are only designed for temporary use and do not fulfil the requirements for permanent living comfort and construction quality.

Despite the standardised construction method, modular construction at ALHO offers a high degree of flexibility. Each building is planned individually - from the floor plan to the façade to the interior fittings. This results in residential buildings that can be adapted exactly to the requirements of the project and the conditions of the location in terms of function and design.

A wide variety of architectural expressions are possible: different window formats, façade materials, colour accents or entrance areas can be used in a targeted manner to give the building its own unique character. Architecture and recognisability are retained without sacrificing the advantages of industrial prefabrication.

Modular residential buildings are subject to the same legal requirements as conventionally constructed buildings, including the respective state building regulations, the Building Energy Act (GEG) and technical regulations such as DIN standards. Particularly relevant here are DIN 4109 for sound insulation between residential units, DIN 18040-2 for barrier-free construction and DIN 4102 for fire protection. Requirements for energy efficiency, ventilation and thermal insulation in summer must also be met.

ALHO ensures that all these requirements are integrated into the planning right from the start. Thanks to precise industrial production in the factory, particularly high execution quality and dimensional accuracy are achieved, for example in terms of airtightness or thermal bridge protection. Our modular buildings not only meet all legal standards, but can also meet higher requirements, e.g. for sound insulation or energy efficiency, if necessary, for example for KfW subsidy programmes.

Climate-neutral residential construction: Thinking about tomorrow today

The pressure to build sustainably is growing: climate targets, legal requirements such as the EU taxonomy, ESG criteria and the Building Energy Act are presenting developers, investors and local authorities with new challenges. Anyone creating living space today must not only plan efficiently, but above all in a future-proof and climate-friendly way.

With ALHO's modular construction method, you can rely on a system that is geared towards sustainability from the outset. Thanks to precise prefabrication in the factory, resource-saving processes and energy-optimised planning, buildings are created with a particularly low carbon footprint. Our residential buildings can be designed to meet efficiency house standards such as EH 40 or EH 55, right through to the realisation of virtually climate-neutral buildings.

The modular construction method also fulfils many requirements for circular construction: The constructions can be dismantled, reused and designed for maximum durability. Modern building technology, such as photovoltaics, heat pumps or battery storage, can be seamlessly integrated. The result is not only high-quality, economical residential buildings, but also genuine future solutions for sustainable neighbourhoods, eligible projects and responsible construction for future generations.
