Landscape perception in architecture

The landscape in architecture is a operational field that is built through perception. What we call landscape It emerges from the intertwining of physical form (topography, vegetation, built fabric, voids, infrastructure), atmospheric conditions and light, uses and times of crossing, memories and expectations of those who experience it.

For the designer, therefore, to perceive already means to measure: identify hierarchies, recognize continuities and fractures, understand where a place "invites" you to move or stop, where it orients or disorients.

The key lies in transforming “walking” and “observing” into real design tools, moving from the sequential reading of spatial experience to the construction of coherent and verifiable formal choices.

Experiencing the landscape as a tool for perceptual relief

The "on-the-go" survey produces data that a static survey is unlikely to provide: compressions and dilations of the visual field, variations in altitude perceived as fatigue or lightness, acoustic thresholds, changes in microclimate, alternating shadow and glare, the relationship between distance and detail.

We must start from a fundamental assumption, that is, that the project is experienced over time and along trajectories: the route is a dynamic section.

The concept of fits into this framework architectural promenade, associated with Le Corbusier, which places the itinerary at the centre of the reading and construction of space. Architecture is understood through a sequence of views and steps, not at a glance.

Operationally, during the walk, the following are recorded: “event points” (turns, gaps, changes in slope, crossings), and for each of these the dominant directions, wings, openings, vanishing lines, presence of landmarks, quality of the ground (grip, rhythm, discontinuity), and average travel times are noted.

These notes become a project dataset: the basis for deciding where to introduce a filter, a viewpoint, a visual cut, a pause or, conversely, a “transfer” section devoid of attractions.

Seriality of the gaze: designing for shots and transitions

When we move, perception proceeds through successive montages: apparitions, occlusions, revelations.

The tradition of townscape (and in particular the “serial vision” made famous by Gordon Cullen) offers a useful lexicon to describe this kinematics of urban and landscape space: not just three-dimensional composition, but composition in time, governed by thresholds, changes of direction, “surprises” and closures.

In practice, serial vision can be translated into a series of schemes:

• Occlusion planes (plant wings, walls, differences in level) that regulate when and how a view is revealed;
• Highlights (openings onto a void, onto a notable front, onto a waterline);
• Thresholds (porticos, bridges, changes in material, narrowings) that signal a change in “environment”.

Designing with this approach means draw sequences, not just objects: architecture and landscape are conceived as dynamic systems, verifiable in their coherence between masterplan, perspectives and daily use.

Readability and orientation: mind map as a criterion

If the landscape is to be habitable, it must also be interpretable. Kevin Lynch made this idea operational by introducing the theme ofimageability and a taxonomy of elements that structure urban perception: paths, edges, neighborhoods, nodes, references.

This interpretation allows the designer to intervene in a targeted manner, strengthening orientation and recognisability without resorting to invasive signage or formal excesses.

Applied to the architectural landscape – urban, peri-urban or territorial – Lynch's taxonomy becomes an operational tool:

• I itineraries they are not just road infrastructures, but all real and perceived crossing lines, from paths to rows, from alignments to visual axes;
• I margini they are legible discontinuities – slopes, walls, embankments, clear changes in texture – that define fields and thresholds;
• I Nodi they coincide with points of choice or spatial intensity, such as intersections, open spaces, access points, where it is appropriate to concentrate quality and recognisability;
• I landmark they act through contrast and uniqueness, and become stable references over time: plant emergencies, towers, special volumes, artistic elements.

The recurring mistake is to introduce formal complexity where structural clarity is needed. The logic of the "mind map" suggests the opposite: build simple hierarchies, make transitions legible, and allow the space to orient those who pass through it through its very form.

Affordance and design: what space "makes us understand"

An environment does not communicate only through signs or symbols: it communicates because its physical configuration suggests possible behaviors.

James J. Gibson he defined affordances as the opportunities for action that the environment offers to those who pass through it, directly connecting perception and behavior.

In the relationship between architecture and landscape, this principle becomes operational: the built form must render immediately understandable uses, limits and possibilities through geometry, materials, slopes, supports, edges and heights, without the need for external mediations.

An effective seat, for example, isn't just an object, but a combination of elevation, depth, surface temperature, protection, and view. A legible path isn't a simple line, but a continuous structure of soil, drainage, rhythm, and tolerance for actual use. A threshold works when it introduces a distinct change in light, texture, sound, or scale, signaling the entrance to another space.

This approach allows to reduce the distance between design and use: the form becomes an implicit instruction and guides behavior without imposing it.

From experience to drawing: senses, time and horizontality

Contemporary architectural theory has shown how theexperience of space does not depend only on visual perception, but involves the whole body: touch, sound, smells, balance, rhythm of walking.

Juhani Pallasmaa, in particular, he criticized the excessive centrality of the gaze, recalling architecture to the construction of atmospheres based on matter, detail and human scale: the landscape is understood through the body that passes through it, not just through the image.

Designing in this context involves structuring work across multiple, easily understandable and operational levels. An effective method can be structured into three "layers" compatible with standard workflows. CAD and BIM:

1. Perceptual layer: analysis of views, visual cones, shadows, stopping points, and spatial sequences. This is the level that governs what you see and when you see it;
2. Performance layer: definition of the soil and section – slopes, drainage, roughness, ride comfort – understood as concrete conditions of the physical experience;
3. Territorial layer: the landscape as a continuous network of surfaces, connections, and times, according to a logic that integrates built and open space into a single system.

The result is a replicable method: you walk to collect perceptual data, you order the experience into sequences, you check the legibility of the space and, finally, you translate everything into clear drawings.

The project must not only describe what will be built, but must also anticipate how it will be perceived and experienced over time.

Conclusions

Taking the perception of the landscape as an integral part of the project means thinking of architecture not as an isolated sphere, but as a spatial device that acts in lived time and space.

Walking, observing and measuring the real experience of places It allows us to understand how movements, gazes, and behaviors are already inscribed in the structure of the environment. The quality of an intervention lies not only in its form, but in the coherence between perceptual sequence, legibility, and everyday use.

Integrating these levels into the design process allows architecture to engage with the surrounding landscape, producing more suitable spaces and buildings capable of lasting function, because they are grounded in the concrete experience of those who pass through them.
