Project Spotlight: Transformation of a 1930s Apartment in Rotterdam Kralingen

At Global Bouw, we are proud to go beyond construction alone. We transform spaces with respect for their character and history. This case study highlights one of our most distinctive projects: the complete renovation of a 1930s apartment in the charming Kralingen district of Rotterdam.

This project presented both a challenge and an opportunity to showcase our expertise in renovating older homes, carefully combining authentic details with modern living comforts.

Revival of authentic charm

The apartment purchased by our clients had great potential but was in average condition. Original interior elements such as parquet floors, doors, and decorative details were heavily worn and in need of restoration. The layout—typical of 1930s homes with small, enclosed rooms—no longer met contemporary living requirements.

The main project objectives were:

• Preservation and restoration of original elements: retaining as many authentic details as possible, including parquet floors, doors, moldings, and other historical features.

• Modernization of the layout: creating an open kitchen and functional living spaces that meet the needs of a modern family. Reorganizing zones to allow more natural light and improve internal circulation.

• Renewal of technical installations: complete replacement of outdated electrical systems, heating systems, water pipes, and drainage. Installation of modern ventilation and air-conditioning systems.

• Improvement of energy efficiency: optimizing thermal insulation of walls, floors, and ceilings, as well as installing energy-efficient windows and doors.

• Contemporary design: integrating modern design elements that harmonize with the apartment’s historical style.

• Strict adherence to budget and schedule: timely and cost-efficient project delivery.

The Global Bouw team—consisting of architects, interior designers, and engineers—developed a detailed renovation plan fully aligned with the client’s wishes and expectations.

Execution: a combination of tradition and innovation

The renovation was carried out in several complex phases. Old structures were removed, damaged elements carefully dismantled, and the apartment prepared for new technical installations and high-quality finishes.

Key work phases included:

• Demolition and preparation: removal of old finishes, pipes, and electrical wiring; stripping outdated plaster and paint. Load-bearing structures were reinforced where necessary.

• Technical installations: installation of new water and drainage systems, modern electrical installations in accordance with current safety and energy standards, placement of a new heating system (radiators and/or underfloor heating), and installation of ventilation and air-conditioning.

• Restoration of original elements: careful restoration of parquet floors, doors, windows, and moldings using specialized craftsmanship and appropriate techniques.

• Apartment renovation in Rotterdam – new layout: construction of new partition walls, optimization of the floor plan, and application of sound insulation for optimal living comfort.

• Finishing works: plastering and painting, tiling in the kitchen and bathroom, installation of sanitary fixtures and lighting.

• Flooring: restoration and finishing of the original parquet, combined with modern flooring solutions in functional areas.

• Windows and doors: restoration of existing elements or replacement with energy-efficient alternatives that match the historical character.

• Final finishing and furnishing: installation of skirting boards, switches and sockets, furniture, and decorative accents.

During the restoration of the parquet floor, we discovered missing sections. Our craftsmen managed to source original parquet material and reintegrate it, allowing the floor to retain its historical appearance and cohesion. Special techniques were also applied during the restoration of the moldings to accurately reconstruct details and textures.
