An internal courtyard that is no longer merely an afterthought, a kitchen oriented towards the best light, or a restaurant where greenery structures the dining area: trends in biophilic architecture are not about filling a space with plants. They are about designing a more precise relationship between people, light, materials, air and the passage of time.

For an urban home or a hospitality business, the question is not whether to incorporate nature, but how to do so without reducing it to mere decoration. Well-executed biophilic architecture enhances the perception of space, supports daily activities and builds an identity that is not dependent on passing fads.

Biophilia moves from being an aesthetic device to a design principle

Biophilic architecture is based on a simple idea: our spatial experience improves when there are real connections with natural systems. This can manifest itself in vegetation, but also in views, cross-ventilation, changing light, water, mineral textures or a layout that allows the outdoors to be recognised from different points within the floor plan.

The difference is crucial. A ficus plant in a corner does not transform a dark, poorly ventilated room that is disconnected from its surroundings. On the other hand, opening up a view onto a terrace, restoring the depth of a gallery or introducing a planted courtyard can completely change the way a flat is lived in.

In comprehensive refurbishments, this approach requires action to be taken before selecting finishes. Orientation, openings, the relationship between rooms and circulation are the first tools to be considered. Materials, vegetation and lighting then follow as layers that reinforce a coherent spatial strategy.

Practical trends in biophilic architecture

Natural light as an active material

Light remains the most valuable element in a home or commercial premises. The trend is not towards indiscriminate opening up, but rather towards controlling how light enters, how it reflects and how it changes throughout the day. Direct light can be excellent in a breakfast area but too harsh at a workstation or a restaurant table.

This is why glazed partitions, transparent sliding doors, textured glass and textile or louvre filters are becoming increasingly common. They allow light to reach interior rooms without compromising on privacy or thermal comfort. In a Barcelona flat facing an inner courtyard, for example, a refurbishment can transform the kitchen into a bright transitional space between the living area and a terrace, rather than keeping it as an isolated room.

Artificial lighting should follow this same principle. It is best to avoid flat, uniform lighting that would wash out the atmosphere created during the day. A combination of ambient, task and accent lighting allows each setting to be adapted to the space’s actual use.

Integrated greenery, not an afterthought

Indoor vegetation works best when it forms part of the architecture: built-in planters, benches with integrated planting, shelving incorporating shade-loving species, or courtyards visible from the main areas. In this way, it makes its presence felt without obstructing the way or requiring makeshift solutions.

In the hospitality and catering sectors, planting can also help shape the experience. It can separate tables without creating visual barriers, soften harsh acoustics or guide the flow of movement towards a bar, a terrace or a waiting area. The key lies in selecting plants according to the available light, the level of maintenance required and the scale of the project. A spectacular living wall is of little value if it requires conditions that the premises cannot guarantee.

It is also worth distinguishing between the occasional inclusion of plants and a comprehensive green strategy. In a loft with limited light, a few well-placed species can be more elegant and sustainable than a jumble of plant pots. In a house with a courtyard, on the other hand, vegetation can become the visual and climatic centrepiece of the layout.

Materials that convey naturalness and durability

Wood, stone, lime, ceramics, natural fibres and metals with honest finishes remain relevant, although the current trend steers clear of a prefabricated ‘rustic’ look. The aim is not to imitate nature, but to work with materials that possess texture, depth and the ability to age gracefully.

A stone worktop, matt ceramic flooring or well-proportioned wooden joinery provide a tactile quality that overly synthetic surfaces rarely achieve. The choice depends on the intended use. A home allows for certain delicate finishes that might not be suitable for a high-turnover restaurant or a hotel lobby.

The value lies in the combination. A space can be both contemporary and warm if it balances a mineral base with wood, textiles and a colour palette inspired by the surroundings. There is no need to resort to obvious greens in every element. Earthy tones, clay, sand, muted olive or stone grey often create a more sophisticated and versatile atmosphere.

Patios, terraces and liveable outdoor spaces

Small outdoor areas have taken on greater importance. A terrace need not be the place where two chairs and a plant pot are simply shoved off to once the building work is finished. It can be a functional extension of the living room, an outdoor dining area, a relaxation space or a feature that brings light and greenery into the interior.

In urban buildings, thresholds are particularly significant: balconies, galleries, light wells and recesses offer potential when designed as liveable spaces. A large-format sliding door, seamless flooring between indoors and outdoors, or an integrated planter make the boundary clearer and more useful.

However, opening up a space to the outdoors requires solutions for sun protection, drainage, privacy and maintenance. In Barcelona, exposure to the sun, wind and periods of heat influence both the choice of plants and the materials used. Biophilia cannot ignore the local climate.

Well-being, acoustics and comfort: the less visible aspect

One of the most interesting trends is the shift from visual biophilia to sensory biophilia. Users do not merely perceive a space through what they see, but also through sound, temperature, the feel of materials and air quality.

Porous materials, textiles, timber and vegetation help to reduce reverberation, particularly in restaurants, offices or sports clubs. However, they are no substitute for an acoustic study where the project requires it. A well-integrated sound-absorbing ceiling can be more effective than simply adding decorative elements.

Natural ventilation is another key factor, although it is not always viable as the sole solution. In a through-house, it can be organised very efficiently. In a deep-set premises or a building with façade restrictions, it will need to be combined with carefully planned installations. True comfort stems from this coordination, not from a single measure.

Designing biophilia without resorting to clichés

The repetition of certain design codes has led to interchangeable interiors: wooden slats, moss walls, fibre lampshades and a collection of tropical plants. These elements can work, but they should not replace an architectural concept.

A bespoke project begins by understanding who will use the space, what light it receives, what its structural limitations are, and what character it should convey. For a family penthouse, the priority might be to create continuity between the kitchen, living room and terrace. For a restaurant, it might be about managing the flow of movement, the acoustics and how long customers stay. For a hotel, greenery can enhance a memorable arrival without compromising day-to-day operations.

At FFWD Arquitectos, our approach combines architectural planning and interior design so that these decisions do not feel like an afterthought. When nature is incorporated effectively, it plays a part in the layout, the construction details and the project’s overall identity.

What to decide before incorporating biophilic elements

Before selecting plant species or cladding, it is advisable to define the acceptable level of maintenance, the availability of light, watering requirements and the intended use of each area. It is also necessary to assess the durability of the finishes, particularly in commercial projects where wear and tear is an inherent part of the space’s life.

Investment should be focused where it has the greatest impact. Sometimes, reclaiming an existing space, improving a passageway to the terrace and designing a bespoke planter can achieve more than a large-scale planting scheme. At other times, a dark courtyard requires a technical solution involving drainage, lighting and planting to become a true focal point of the project.

The most interesting biophilic architecture does not seek to appear natural at first glance. It aims to ensure that light, air, materials and vegetation enhance the usability of each room and make it easily memorable. This is a good starting point for transforming any refurbishment or new space into a place that offers a higher quality of everyday life.
