45° Grid House: A Contemporary Concrete House Design by Objekt Architecten

Introduction to a Bold Architectural Experiment

Located in Meise, Belgium, the 45° Grid House by Objekt Architecten redefines residential architecture through a geometric, concrete-driven spatial concept. Completed in 2024 for a family of four, this 220-square-meter residence transforms conventional living with a floor plan rotated at a 45-degree angle—creating a unique experience of movement, light, and spatial discovery. Rooted in the family's passion for art and design, the home functions as both a living space and an exhibition platform.

A Contemporary Approach to Concrete House Design

Objekt Architecten’s design embraces contemporary concrete house design principles by blending robust structural elements with minimalist material finishes. Rather than conceal the construction framework, the architecture emphasizes its raw textures and geometry. Brick walls are coated with chalk paint instead of plaster, revealing the underlying materiality while softening it with a matte, tactile finish. The concrete presence continues inside through exposed beams, height variations in the roof structure, and seamless transitions between indoor and outdoor spaces.

A Grid System with a Twist

At the core of the house is a radical spatial strategy: a grid of square rooms rotated 45 degrees, forming a diagonal axis throughout the home. This orientation not only breaks the monotony of standard rectangular layouts but also eliminates wasted circulation space. Each of the 13 rooms connects directly to the next, fostering a journey-like experience as inhabitants move through the house. The layout encourages intuitive navigation, unfolding the residence one space at a time.

Light, Connection, and Centrality

A central patio acts as the luminous heart of the home, bringing natural light deep into its interior. This element serves multiple purposes—it becomes a visual anchor, a source of daylight, and a meditative garden space. Views through the home are punctuated by glimpses of this core, reinforcing the spatial logic of the 45° grid while anchoring the resident’s daily rhythm in natural light and seasonal change.

Material Palette and Spatial Clarity

A calm, neutral palette defines the interiors, allowing the family’s art and design collection to take center stage. The architectural finishes intentionally fade into the background—chalk-painted bricks, natural concrete, and carefully detailed structural components are choreographed to create a serene and coherent setting. This restrained materiality extends outdoors, where the same flooring used indoors continues across the terrace and garden platform, visually stitching the entire plot into a unified design narrative.

Architectural Expression through Detail

From an articulated cornice that wraps the perimeter to the staggered roof beams that conceal mechanical systems, every detail contributes to the aesthetic and functional clarity of the house. High ceilings in key spaces amplify the sense of openness, while the absence of traditional decorative elements focuses attention on spatial volume, light interplay, and the curated objects within.

A Personalized Concrete Home for Modern Living

The 45° Grid House is not merely an abstract exercise in geometry—it is a tailor-made residence that reflects the lifestyle and values of its occupants. Through its contemporary concrete house design, the home merges architectural boldness with domestic intimacy, offering a sophisticated response to the family’s creative aspirations and spatial needs. Objekt Architecten has delivered a design that challenges conventions, creating a home where everyday life intersects with architectural exploration.
