Office to residential: conversion with modular construction<\/h2>\n

Pacarada Modular Building Systems, Kelkheim (Taunus), Germany \u00b7 Last updated: October 2026<\/p>\n

Vacant office buildings can become homes. This saves land, keeps the structure and is often faster than demolition and new construction. Modular construction helps in three places: with prefabricated bathroom modules inside the existing building, with extensions and with added storeys.<\/p>\n

\"Conversion
Darmstadt: an office building becomes 197 homes.<\/figcaption><\/figure>\n

Why conversion is in demand<\/h3>\n

In many cities office space stands empty while homes are missing. Office buildings are often centrally located, connected to roads, utilities and public transport, and have a sound skeleton of columns and floor slabs. Converting instead of demolishing uses what is already there: a large share of the embodied energy of a building is in its structure.<\/p>\n

What is checked before the conversion<\/h3>\n\n\n\n\n\n\n\n\n\n\n\n\n
Topic<\/th>\nQuestion<\/th>\n<\/tr>\n<\/thead>\n
Structure<\/td>\nWhat loads can columns, floors and foundations take, including added storeys and new bathrooms?<\/td>\n<\/tr>\n
Building depth and daylight<\/td>\nCan apartments be arranged so that all habitable rooms have windows?<\/td>\n<\/tr>\n
Room height and grid<\/td>\nDo apartment layouts fit the column grid? Is there enough height for new floor build-ups and services?<\/td>\n<\/tr>\n
Fire protection<\/td>\nDo the building class, escape routes and the requirements for party walls and floors change?<\/td>\n<\/tr>\n
Sound insulation<\/td>\nDo floors and new party walls reach the values required for apartments under DIN 4109?<\/td>\n<\/tr>\n
Building services<\/td>\nWhere do the risers for bathrooms and kitchens run? Which heating and ventilation are possible?<\/td>\n<\/tr>\n
Hazardous materials<\/td>\nAre there contaminants in the existing building that must be removed before the conversion?<\/td>\n<\/tr>\n
Planning law<\/td>\nIs residential use permitted at the location? The change of use needs a building permit.<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n
