House on the City Walls: A Harmonious Blend of History and Contemporary Design

A Timeless Architectural Revival in Cascais, Portugal

Nestled in the heart of a historic seaside village, the House on the City Walls is an exceptional architectural renovation that bridges medieval heritage with contemporary living. Designed by PAr Plataforma de ARquitectura in collaboration with Rita Alves M arch, this 373 m² residence seamlessly integrates with the centuries-old medieval defensive walls, preserving their historical essence while introducing modern spatial ingenuity.

A Historic Structure Reinvented

The original structure, built against the medieval fortifications, had evolved over time through a series of additions and modifications. The design intervention did not aim to expand the building’s footprint but rather to reimagine the internal spaces. By reconfiguring the existing layout, the architects infused the residence with new life while maintaining its intrinsic medieval spirit.

A New Spatial Experience

Every room in the house was thoughtfully reconsidered to enhance both function and atmosphere. The kitchen was transformed into a grand yet intimate gathering space, featuring recessed countertops and deep cabinetry that echo the depth of the ancient walls. The combination of arches and niches further enriches its historical character.

One of the most striking transformations was the creation of a double-height library, formed by merging three former rooms. This innovative space fosters a vertical connection between floors, featuring an elegant brass staircase that adds a sculptural quality while maintaining a sense of playfulness.

By carefully reconfiguring walls and openings, the project improves natural light distribution and fluidity between communal areas. Meanwhile, private spaces were enhanced to provide a greater sense of retreat and intimacy. The incorporation of fireplaces and candle-lit areas introduces a sustainable and cozy ambiance, resonating with the warmth of traditional dwellings.

Materiality: Honoring Medieval Craftsmanship

The material palette was meticulously chosen to reinforce the medieval aesthetic while ensuring durability and authenticity. Massive limestone elements were carved into countertops, benches, showers, and basins, paying homage to time-honored stone masonry techniques. Exposed solid wood boards were used across ceilings, doors, and shutters, adding texture and warmth.

To further accentuate the handcrafted appeal, all hardware and hanging rods were fabricated in natural brass, complementing the raw yet refined aesthetic. Traditional lime-based stucco and paints were applied to the walls, ensuring breathability and historical continuity. The slim iron-framed windows preserve the house’s architectural integrity while maximizing views and light.

Custom-Designed Furniture: A Cohesive Vision

A significant portion of the furniture was either custom-designed or carefully selected to enhance the project's overall narrative. Solid wood elements dominate the interior, reinforcing the residence’s deep-rooted connection to traditional craftsmanship while harmonizing with the architectural language of the space.

A Marriage of History and Innovation

The House on the City Walls is a testament to how historical preservation and contemporary design can coalesce into a seamless living environment. By embracing ancestral materials and construction techniques, while ensuring spatial lightness and fluidity, the project offers an immersive experience in architectural storytelling. It stands as a beacon of sustainable renovation, where the past and present coexist in perfect harmony.
