The Resurgence of Mid-Century Modern: Screen Blocks in Contemporary Design

Posted by

Mid-century modern architecture has been enjoying a strong revival in recent years. Among its defining features, screen blocks (also called breeze blocks or decorative clay blocks) stand out – delivering pattern, light, ventilation, and privacy all in one. As South Africa and particularly cities like Cape Town and Pretoria embrace urban renewal, projects such as Bendehuis in the Old East Precinct in Hazelwood demonstrate how mid-century design motifs (including screen blocks) can be reinterpreted in a modern, high-quality, and people-centric way.

What Are Screen Blocks?

Definition & Function: Screen blocks are masonry units with open patterns. They allow air and light to pass through, while offering shade, visual interest, and architectural rhythm.
Mid-Century Roots: Popular in the 1950s-60s, especially in warm climates, screen blocks helped cool buildings, create texture, and produce playful light and shadow patterns.
Modern Appeal: In contemporary design, they are appreciated for aesthetic value and functional benefits, including ventilation, passive cooling, and adding a decorative narrative to building façades or courtyards.

Why Screen Blocks Are Making a Comeback

Several trends drive their resurgence:

Passive Design:
With an increased focus on energy efficiency and climate responsiveness in modern buildings, features that aid ventilation, reduce heat gain or provide shading are in demand. The openwork design of screen blocks helps moderate temperatures, reducing the need for mechanical cooling.
Blending Indoor & Outdoor Spaces:
Screen blocks are ideal for semi-open walls, courtyards, boundary walls, and balconies. They allow visual connectivity and natural light, while providing privacy.
Pattern, Texture & Character:
The bold geometric patterns of screen blocks are striking. They allow architects to introduce artistic detail, breaking up planar façades with texture and depth.
Heritage & Nostalgia:
As awareness of architectural heritage grows, mid-century design has become fashionable again. There’s a desire to bring back tactile, human-scale craftsmanship and details that balance with impersonal materials like glass or steel.

Screening in Bendehuis: Lessons from The Old East Precinct

The Bendehuis development offers many lessons and parallels that align well with the mid-century screen block aesthetic.

Placemaking Through Pattern & Connectivity:
Atterbury’s approach in Old East Precinct is about reconnecting spaces (The Club, The Village, Village Walk, Bendehuis, and Pantry by Marble) to create walkable precincts. This kind of connectivity and spatial rhythm is very much in the spirit of screen block usage, which often delineates zones without rigid barriers. Atterbury
Designing for Climate & Comfort:
Old East Precinct’s infrastructure upgrades (such as the stormwater, roads, pedestrian flow and parking) demonstrate that design is not just about looks but about liveability. Screen blocks similarly balance design and climate: offering airflow and light while mitigating harsh weather, especially in South Africa’s varied climates. Atterbury
Human-Centric, Mixed-Use Spaces:
The Village (cafés, restaurants spilling onto pavements), Village Walk, and other elements in Old East Precinct show how spaces are being designed for community, engagement, local business, and daily human interaction. Screen blocks can help in these environments – shading outdoor dining zones, creating semi-enclosures for comfort without closing off the welcoming feel. Atterbury

How to Incorporate Screen Blocks Well (Inspired by Bendehuis & Mid-Century Principles)

If you’re considering screen blocks in your next build or renovation, here are some best practices drawn from Bendehuis’ ethos and design thinking:

Select Patterns Respectfully: Choose block patterns that respond to sunlight angles, views, and privacy needs. Some facades may benefit from dense patterns; others from more open ones.
Integrate with Context: Let the blocks relate to neighbouring buildings or the site’s history. Materials, colours, and scale should harmonise. Just as Bendehuis merges its old and new, your screen blocks should not feel tacked on.
Consider Ventilation & Light: Use screen blocks in areas where natural airflow and diffused light are wanted (e.g., verandas, corridors, boundary walls). They help reduce cooling loads.

Challenges & Considerations

Installation: Planning your layout in installing a screen block wall is crucial for accuracy, alignment and efficiency. It ensures walls are level, estimates material needs accurately and maintains quality control during construction, leading to a structurally sound and visually appealing finished product.
Weather & Durability: For cities near the coast, it is important to take note of your geographic location and the relevant exposure zones. Klay’s Latte products have an exposure zone rating of 1, Espresso zone 1-2, and Chai products zone 1-3.
Regulatory & Structural Constraints: Klay screen blocks are designed as non-load bearing units, this should be taken into account when planning the height and width of your screen block wall.

Why Bendehuis’ Model Matters for Screen Block Revival

Bendehuis stands out as more than just redevelopment. It exemplifies:

Long-Term Vision: Not simply building a structure but nurturing a place that will evolve. Screen blocks, with their timeless appeal, fit such long-term design approaches. Atterbury
Community-First Design: From preserving old structures to designing for people over cars, the project shows how architectural detail (including decorative elements) plays a role in identity and belonging.
Quality Infrastructure Underpinning Design: Screen blocks may look good, but without sound planning (for drainage, lighting, orientation), their impact can falter. Atterbury

The Timelessness of Screen Blocks in Modern Urban Design

Screen blocks are more than a nostalgic flourish: they embody functionality, beauty, climate responsiveness, and identity. As the mid-century modern style resurges, architects and developers can look to projects like Bendehuis to see how elements like pattern, lightness, and public engagement are resurfacing as integral parts of meaningful, liveable cities.

By combining modern performance standards with mid-century aesthetics (including screen blocks), new developments can achieve character, comfort, and community. Bendehuis proves that with thoughtful planning, heritage respect, and good design infrastructure, these revivals aren’t just trendy, they’re lasting.
