2025 Design Trends: A Timeless Vision by HollandGreen

As we transition into 2025 and the age of the “anti-trend,” HollandGreen’s commitment to timeless, sustainable design resonates more strongly than ever.

This year, we predict a focus on enduring design principles that prioritise harmony, wellness, and ecological sensitivity. Here’s how we see key architectural, interior, and landscape trends evolving to reflect values that transcend fleeting fads.

Architecture Trends

Biophilic Design: Nature as an Essential Framework

Biophilic design is evolving beyond a visual style to become an essential framework for enhancing wellness and connection within the home. Elements like expansive glazing, green roofs, and abundant natural light bring a breath of nature into both heritage and modern spaces. At HollandGreen, we believe these features not only alleviate stress but foster health, creating spaces that harmonise effortlessly with their surrounding landscapes.

Sustainable Design: Enduring and Responsible

Sustainable design remains at the core of our work as we continue to prioritise solutions that blend aesthetics with environmental responsibility and the longevity of good design. We focus on intelligent design, optimising the building envelope, and integrating low-carbon materials, energy-efficient systems, and water conservation techniques to ensure long-term value. These principles not only contribute to ecological well-being but also enhance the quality of life for our clients, creating spaces that stand the test of time and remain resilient for generations to come.

“Whether designing a contemporary new build, renovating an existing structure, or working with heritage and listed properties that require more bespoke solutions, sustainable architecture is about creating spaces that endure. A well-designed building, regardless of its age, should blend innovation and respect for the past while prioritising energy efficiency and intelligent design. By ensuring that these spaces are not only functional but resilient, we can create environments that will stand the test of time, minimising environmental impact for future generations.”

Internal Glazing

In 2025, internal glazing will be instrumental in enhancing spatial connectivity and light within homes while preserving each room’s unique purpose. For heritage and listed properties, traditionally characterised by darker interiors, this technique reimagines spaces to feel airy, interconnected, and intimate. The juxtaposition of structured glazing, such as Corten steel, against the organic warmth of timber introduces a design feature in itself. Glazed partitions and internal windows create subtle yet effective transitions, defining spaces without interrupting the overall flow.

“Internal glazing also offers a nuanced way to modernise heritage properties, harmonizing traditional architecture with contemporary light flow and openness. By integrating elements like slim-framed steel or bronze, these partitions provide a refined edge, complementing natural materials while enhancing visual depth. This thoughtful layering not only maximizes daylight but also respects the integrity of individual rooms, allowing each space to maintain its distinct ambiance while contributing to a cohesive, light-filled environment.”

Interior Design Trends

Mixed Metals: A Timeless Sophistication

The artful combination of mixed metals will continue to refine elegance in 2025 interiors. HollandGreen’s approach to metallic contrasts is both intentional and delicate, layering finishes to enhance light, create texture, and draw interest to hardware and furniture. This sophisticated blend of metals introduces a timeless appeal, adding depth and character to interior spaces that feels current yet enduring.

“Blending metals within spaces is an effective way to create rich, immersive interiors. Carefully balancing metal textures adds depth and warmth, enhancing the room’s character and making the space feel more dynamic and inviting.”

Earthy Tones and Warm Neutrals: Grounding Interiors

Warm, natural colour palettes will define interiors, creating environments that are both comforting and chic. We anticipate a sustained embrace of earthy hues—deep browns, terracotta and reds, alongside warmer whites and neutrals – as these tones foster a grounding, relaxed aesthetic. At HollandGreen, we select these shades thoughtfully, pairing them with natural materials to produce interiors that are rich and inviting.

“When approaching the interior of a new build property, it’s important to infuse warmth and individuality into the space. New builds can sometimes feel too clean or clinical, so adding character is key. Incorporating vintage or antique finds, unique furnishings, or custom details helps to bring personality into a space, balancing the modern with the timeless. Our goal is to create a home that feel full of soul, where every element tells a story and reflects the people who inhabit it.”

Eclectic Interiors

Eclectic interiors celebrate the art of mixing contrasting elements—blending the old with the new, patterns with simplicity, and crafting unexpected spaces. This design approach brings character, depth, and personal expression to every room. The key is to embrace contrasts and create harmony from them, resulting in spaces that feel unique and full of life. It’s about finding beauty in diversity and celebrating individual style.

“When working with heritage properties, creating an eclectic interior is all about balance. It’s about blending the charm of original features with modern design elements. Mixing vintage with contemporary pieces, and combining rich textures with simpler designs, adds depth and character to the space. The aim is to create a home that honours the past while feeling fresh and inviting, where old and new complement each other perfectly.”

Landscape Design Trends

Luxurious Outdoor Kitchens

As indoor-outdoor living grows more popular, we’re seeing outdoor spaces transform into fully equipped extensions of the home. In 2025, luxurious outdoor kitchens will become focal points in landscape design, featuring high-quality appliances, durable cabinetry, and weather-resistant materials for year-round use. HollandGreen designs outdoor spaces with a balance of functionality and elegance, ensuring they’re ideal for both relaxation and entertaining. Outdoor kitchens, comfortable seating, and heating options bring versatility, allowing clients to enjoy nature in comfort through every season.

“A wonderfully designed outdoor kitchen can truly enhance the flow between indoor and outdoor living. Our approach is to craft outdoor spaces that are practical, elegant, and sustainable, perfect for hosting special moments. With careful attention to layout and the use of high-quality materials and craftmanship, we ensure these kitchens become true destinations – places where family and friends can gather, cook, and enjoy each other’s company, all while staying connected to the outdoors, no matter the season.”

Mark Latchford, Director of Landscape Design

Wild Planting and Naturalistic Gardens

With a heightened focus on ecology and sustainability, wild planting and naturalistic gardens will be especially relevant in 2025. These gardens represent a commitment to biodiversity, incorporating native plants and wildflower meadows that create resilient ecosystems with minimal maintenance. HollandGreen’s approach to wild planting is ecologically sensitive yet carefully curated, crafting dynamic landscapes that feel both untamed and thoughtfully designed. By inviting nature to flourish, we create outdoor environments that resonate with the unique beauty and vitality of each property.

“Designing gardens with a focus on biodiversity and ecology is about creating enduring spaces that foster a deeper connection to the outdoors. By cultivating environments that invite people to engage with nature, we create gardens that not only stand the test of time but also offer spaces where lasting memories can be made.”

Mark Latchford, Director of Landscape Design

As 2025 unfolds, HollandGreen’s dedication to sustainable, considered design continues to guide us in creating spaces that blend innovation with timeless beauty. We look forward to a year where integrity, wellness, and ecological harmony redefine the role of design in daily life.
