A soundproof apartment building for all residents is born

On October 1, 2025, Tokyu Land Corporation, in collaboration with Livlan Co., Ltd., officially commenced construction of the rental apartment building “(Tentative Name) Sasazuka Project,” which features a total of 76 units, all designed for soundproof living. This apartment is conveniently located just a five-minute walk from the Keio Line’s “Daita Bridge” station and a ten-minute walk from the “Sasazuka” station, making access one of its key attractions. All units will allow for 24-hour music practice and game streaming, aiming for a sound insulation performance of D-70 or higher.

Accommodating various lifestyles

This project offers a range of layouts to accommodate diverse lifestyles, from approximately 30㎡ one-room apartments to about 100㎡ three-bedroom units. Notably, the premium three-bedroom apartments are rare as soundproof rental units. The apartments will employ “floating floor” and “Box in Box” construction methods, ensuring meticulous attention to sound insulation. Furthermore, not only the soundproof performance within the units but also a pathway that can accommodate a C7 size grand piano has been ensured.

A next-generation residence for music lovers

The concept of this apartment building is “next-generation soundproof residence.” It combines the expertise of Tokyo Land’s “Brillia ist” series with Livlan’s “Musision” series to support the lifestyles of music enthusiasts. Through collaborations with companies, it aims to maximize hobbies and work styles.

Growing demand for soundproof apartments

As the population engaging in music practice increases, the demand for soundproof rental apartments in urban areas is on the rise. There are already over 10,000 subscribers registered for the waiting service operated by Livlan, with many people eagerly anticipating such living environments. The “Sasazuka Project” addresses this significant demand and is also close to the Shimokitazawa area, a vibrant hub for music culture, generating high expectations.

Thoughts and prospects

The “(Tentative Name) Sasazuka Project” is a groundbreaking initiative that proposes sound insulation as a new added value for living spaces, providing urban dwellers with a fresh choice. Not only does it cater to the needs of musicians and music lovers, but the excellent soundproofing technology paired with the conveniently located site is also garnering significant attention and expectations. It is anticipated that with the increase of such residences, the urban music culture will continue to thrive.
