The rise of large-format porcelain tiles: Aesthetic and practical advantages for commercial terraces

Large-format porcelain tiles are becoming a top choice for architects and specifiers designing contemporary commercial terraces. Offering a bold, seamless aesthetic paired with outstanding practical performance, these tiles are redefining how outdoor spaces, especially rooftop terraces, are finished and experienced.

With their clean lines, minimal joints and ability to cover expansive areas with fewer interruptions, large-format tiles deliver a sleek, modern look that complements current design trends.

In this blog, we will explore the growing popularity of large-format porcelain tiles and examine why they are an ideal fit for commercial terraces. 

What are large-format porcelain tiles?

Large-format porcelain tiles are defined by their generous dimensions. These oversized tiles create a more continuous surface with fewer joint lines, lending a clean, modern aesthetic that is especially effective in expansive outdoor areas.

Manufactured from high-density porcelain, these tiles are engineered for strength, stability and low water absorption. This makes them particularly well-suited to external applications.

Available in a wide range of finishes, from stone and concrete effects to wood-look designs, large- format porcelain tiles provide architects and designers with the versatility to match or contrast surrounding materials while maintaining a contemporary edge.

The appeal of large-format tiles in modern commercial roof terrace design

Clean lines, open spaces and minimalistic detailing dominate design in 2025. Large-format tiles align perfectly with this aesthetic, offering a sense of scale and sophistication that smaller tiles can’t match. 

Key reasons large-format tiles are chosen for commercial terraces:

• Modern aesthetic: Their large scale supports a sleek, minimal look that complements contemporary design.
• Visual sophistication: Fewer joints and expansive coverage create a refined, high-end appearance.
• Design versatility: Suitable for a variety of sectors such as hospitality, retail, office developments or residential projects.
• Enhanced visual impact: Elevates the overall look and feel of commercial terrace projects by providing a cohesive, premium surface finish.

Seamless aesthetics: Fewer joints, greater impact

One of the most striking benefits of large-format porcelain tiles for commercial terraces is their ability to create a seamless, uninterrupted surface. With fewer joints between tiles, the visual flow of a terrace or rooftop space becomes more refined and elegant. This emphasises clean lines and enhances the overall spatial experience.

The minimal-joint look not only contributes to a contemporary aesthetic but also helps to visually expand the space. In commercial settings such as rooftop bars, hotel terraces or office break areas, this can significantly elevate the perceived value and design quality of the environment.

Fewer joints also mean fewer places for dirt, moss or debris to accumulate which leads to easier cleaning and better long-term appearance.

This combination of aesthetic simplicity and practical upkeep makes large-format tiles particularly attractive for projects where visual consistency and low maintenance are key priorities.

Practical performance: Strength, durability and low maintenance

While large-format porcelain tiles are admired for their visual impact, they also deliver outstanding practical performance. This makes them a smart choice for demanding commercial terraces.

Here are the key functional benefits that make porcelain tiles ideal for commercial use:

·      Strength: Porcelain is incredibly strong and dense. It offers a high resistance to cracking, wear and surface abrasion. This makes large-format tiles ideal for commercial terraces that experience heavy foot traffic or need to withstand the weight of furniture or planters.

·      Durability: Porcelain tiles are non-porous and highly resistant to stains, frost and chemicals. This makes them ideal for commercial terraces where they will be exposed to the elements all year round.

·      Low maintenance: Unlike natural stone, porcelain doesn’t require sealing and routine cleaning is simple. This is an important factor for commercial terraces and environments where owners are looking to reduce upkeep.

Weather resistance and longevity in outdoor environments

Outdoor commercial terraces are constantly exposed to the elements, including:

·      Intense sun

·      Heavy rain

·      Frost 

·      Fluctuating temperatures

Porcelain tiles are specifically engineered to perform under these conditions, offering exceptional weather resistance and long-term durability.

UV stability is a key advantage of porcelain for commercial terraces. Unlike some materials that fade or discolour over time, high-quality porcelain tiles retain their finish and colour, even after years of sun exposure. This ensures the space continues to look sharp and polished well into the future.

Designing safer spaces: Slip resistance and surface options

In commercial terrace design, safety is just as important as aesthetics and slip resistance is a key factor. Porcelain tiles are available in a wide range of textured finishes and slip-rated surfaces to meet the specific safety standards of outdoor public spaces.

Raaft’s Atria porcelain tiles are a safe, non-slip surface. It has a slip resistance of R11 when tested to DIN 51130 (the Ramp Test) and Class 3 when tested to UNE-ENV 12633: 2003 (the Pendulum Test). This ensures that commercial terraces remain safe even in wet conditions. 

Ideal for terraces and rooftop spaces

Large-format porcelain tiles are particularly well suited to commercial terraces and rooftop environments where a balance of aesthetics, performance and structural efficiency is essential. 

Their lightweight yet durable composition makes porcelain a smart choice for rooftop applications where reducing structural load is critical. Combined with Raaft’s adjustable pedestals and joist system, tiles can be installed with integrated drainage and ventilation. This helps to prevent water pooling and extends the lifespan of both the surface and the deck below.
