CK Apartment by rar.studio: A Light-Filled Lisbon Renovation Prioritizing Fluidity, Comfort, and Contemporary Living

The CK Apartment by rar.studio is a thoughtful renovation project located in the heart of Lisbon, Portugal, just steps away from the lively Avenida da Liberdade. Originally purchased as an investment property, the apartment quickly took on a new direction when the client decided to relocate from Bali to Lisbon, transforming the project from a rental asset into a deeply personal home. The result is a serene, light-filled refuge designed to balance the charm of 19th-century Lisbon architecture with modern spatial fluidity and material sophistication.

A Historic Lisbon Apartment Reimagined

Situated inside a late-19th-century building, the apartment reflects a traditional Lisbon typology: long and narrow plots that produce deep floor plans, multiple interior rooms, and dimly lit corridors. rar.studio approached the renovation by enhancing natural light, improving circulation, and redefining the traditional layout to better suit contemporary living.

The architects saw opportunity in the apartment’s inherent constraints. By strategically reconfiguring interior partitions and opening up the plan, the team introduced a sense of spaciousness and connection between the front and rear façades, bringing clarity and brightness into spaces that were once disconnected and dark.

Transforming the Corridor into a Flexible Living Spine

One of the most significant interventions is the redesign of the entry sequence. The original entrance was narrow and compressed, leading to a long corridor dividing the apartment. rar.studio widened this corridor, integrating a niche at the entrance, and transformed it into a continuous, fluid circulation spine that seamlessly incorporates the kitchen.

This reimagined corridor serves as both a functional passage and an architectural element that stitches the home together. The introduction of a stainless-steel central island in the kitchen cleverly addresses structural reinforcement requirements while becoming a striking, sculptural focal point.

A Balanced Layout Between Private & Social Spaces

The reorganized layout supports privacy, comfort, and flexibility:

• Front Façade: The master bedroom and a dedicated office overlook the street, benefiting from ample natural light and acoustic comfort.
• Central Zone: Two bathrooms occupy the core of the apartment, ensuring efficient distribution and maintaining privacy between bedrooms.
• Rear Façade: The kitchen and a secondary bedroom open toward the terrace and connecting social spaces, creating a strong relationship between indoors and outdoors.

This thoughtful arrangement enhances everyday living, offering quiet retreat zones alongside active communal areas.

Metal Structure Extension & Terrace Redesign

At the back of the apartment, a later addition built with a metal structure enabled the creation of a generous opening onto the terrace. rar.studio embraced this opportunity, redesigning the terrace with a soft plant border to create a tranquil outdoor area that visually and spatially expands the interior.

Large windows and strategically positioned openings allow daylight to flood the kitchen and living areas, creating an inviting atmosphere that shifts throughout the day. The terrace acts as an extension of the home’s social core, where indoor and outdoor living blend seamlessly.

Material Choices that Enhance Clarity & Calm

Throughout the apartment, materials were selected for their tactile qualities, durability, and aesthetic coherence. Stainless steel in the kitchen adds a contemporary edge, while warm finishes and natural textures soften the overall ambiance, grounding the spaces in comfort and timelessness.
