Attic Renovation: Dormer or Roof Windows? Maximise Light and Space

Many homes in Rotterdam have an attic with hidden potential. What is now a storage area can, with the right approach, be transformed into a bright workspace, playroom, or even an extra bedroom. Anyone planning an attic renovation soon discovers that light and standing height are the two key factors. That’s why homeowners often choose between a dormer or multiple roof windows to enhance comfort and usability.Global Bouw supports the entire process: from technical inspection to installing a dormer or roof windows in Rotterdam, including finishing, insulation, and ventilation.

Installing a Dormer: Maximum Space and More Standing Height

A dormer immediately transforms the attic into a full living space. The sloped roof is partially straightened, creating significantly more usable floor area. For an attic conversion where a bedroom or office is being created, this is often the most popular choice.

Important to know:

• Front of the house: a dormer at the street side almost always requires a municipal permit.

• Rear of the house: in many cases a dormer can be added without a permit, provided it meets national size and distance regulations.

A dormer also offers excellent opportunities for ventilation and wide light entry. Global Bouw installs both PVC and wooden models, fully insulated and finished according to current safety and building standards.

Roof Windows: Flexible, Energy-Efficient, and Quick to Install

When a dormer is not necessary or not desired, one or several roof windows can make a surprisingly large difference. They take up less space, are budget-friendly, and bring in plenty of daylight instantly. Roof windows are ideal for smaller attics or spaces that mainly need more light, such as a hobby room or guest room.

Advantages of roof windows:

• quick installation without major structural work;

• energy-efficient options with HR++ or triple glazing;

• suitable for natural ventilation;

• can be combined in sets for a symmetrical appearance.

Our specialists advise which type of window best suits your roof structure and your preferences regarding light, ventilation, and heat retention.

Finishing & Insulation: Essential for Comfort
