The Importance of Capsule Room Design in Urban Hotels

The design of capsule rooms in urban hotels has become a growing trend worldwide. This type of accommodation offers an innovative solution for maximising space and providing a unique experience for travellers. In this article, we will explore the reasons behind the popularity of capsule rooms, their impact on the guest experience, and the best design practices that make them stand out.

What are capsule rooms?

Origin and evolution

A brief history of capsule rooms

The capsule rooms were born in Japan in the 1970s, with the opening of the first capsule hotel, Capsule Inn Osaka, designed by architect Kisho Kurokawa in 1979. The idea was to provide an affordable and efficient accommodation solution for workers and travellers who needed a place to sleep without the cost and space of a traditional hotel room.

Evolution of the concept from its creation in Japan to its global adoption

Since its introduction, the concept of capsule rooms has evolved significantly and has been adopted worldwide. Originally, these hotels were designed to provide an economical and convenient option in densely populated urban areas. However, over time, the design has improved, incorporating advanced technology, ergonomic design and sustainable materials, making these spaces appealing not only to budget-conscious travellers but also to those seeking a unique and modern experience.

In the last decade, we have seen the proliferation of capsule hotels in cities outside Japan, such as Singapore, Hong Kong, Paris, and New York, each adapting the concept to local needs whilst maintaining the essence of efficiency and compact design. This global adoption has led to greater diversity in the styles and services offered by these hotels, from luxury capsules to ultra-budget options.

Main features

Size and structure

Capsule rooms are known for their compact size and efficient structure. Below, the key features of their size and structure are detailed:

• Size: Generally, a standard capsule measures around 2 to 4 square metres. This size is optimised to provide sufficient space for sleeping and basic storage, without wasting unnecessary space.
• Structure: The capsules are designed as stackable modules placed in rows within a building. This structure maximises the use of vertical and horizontal space, accommodating a large number of guests in a relatively small area.

Equipment and common amenities

Despite their small size, capsule rooms are equipped with a variety of amenities to ensure a comfortable and enjoyable stay. Some of the most common features include:

• Comfortable bed: With high-quality mattresses and premium bed linen.
• Lighting control: Adjustable and individually controllable lights for each capsule.
• Technology: USB sockets, free Wi-Fi, integrated TV screens, and sometimes smart mirrors.
• Storage: Storage spaces under the bed or in side compartments for personal belongings.
• Security: Electronic locks and safety deposit boxes for valuables.
• Ventilation and climate control: Independent ventilation systems for each capsule, ensuring good air quality and thermal comfort.

Types of capsule rooms: single, double, suites

With the diversification and expansion of capsule hotels, several types of rooms have emerged to meet the different needs and preferences of guests:

• Single capsules: Designed for a single guest, these capsules offer the basics for a comfortable and efficient stay.
• Double capsules: These capsules are slightly larger and designed to accommodate two people, ideal for couples or friends travelling together.
• Capsule suites: For those seeking a little more luxury and space, capsule suites may include additional features such as a private bathroom, extra room to move around, and premium services such as a minibar and high-end television.

Keys to capsule room design

Minimalism and functionality

The importance of minimalist design in creating a welcoming and functional space

The minimalist design is fundamental in capsule rooms due to space constraints. This approach focuses on eliminating excess and concentrating on the essentials, which not only creates a more orderly and visually appealing environment but also increases the functionality of the space. In an environment where every centimetre counts, minimalism helps maximise space usage without compromising guest comfort.

• Space optimisation: By using a minimalist design, all necessary elements (such as a bed, storage, and lighting systems) can be included without overcrowding the space.
• Reduction of visual clutter: A clear and well-organised space contributes to a more relaxing experience for guests, reducing visual stress and promoting rest.
• Ease of maintenance: Fewer elements and smoother surfaces facilitate cleaning and maintenance, ensuring that capsules remain in optimal condition with less effort.

Examples of materials and colours used

Minimalism in capsule room design is often reflected in the choice of materials and colours that promote a sense of spaciousness and calm.
