A multi-storey atrium is experienced from many positions at once: from the lobby, a bridge, a stair, a quiet seat or a room above. Its design succeeds when those viewpoints add up to a coherent interior landscape and when the garden remains practical to inhabit and care for.
Rather than treating the atrium as an empty shaft filled with plants at the end of a project, consider it a sequence of connected rooms. Each level can offer a distinct relationship to greenery while contributing to one larger composition. Start with the building’s daily patterns, then establish spatial hierarchy, circulation, structure and access.
Begin at the ground plane
The lowest level is often the point of arrival and the place where people spend the most time near the planting. Decide whether it should feel like a garden room, a generous passage or a calm waiting space. Set clear routes first. A direct path between entrances, lifts and stairs should not require people to weave through beds or squeeze past seating.
Then arrange the quieter parts: places to sit, edges where a group can gather, and views through the garden toward another destination. Planting can soften transitions and make a large lobby feel less exposed, but avoid hiding wayfinding, reception points or sightlines that help people feel oriented. A low, readable planting edge often works better beside a busy route than a dense, shoulder-height screen.
Give every level a relationship to the whole
Upper walkways and balconies can make a garden feel inhabited at multiple heights. They may bring people closer to foliage, reveal different canopy patterns and provide opportunities for short pauses. Their edges, handrails and structure must work as architecture first; planting should not compromise guarding, access or the clarity of circulation. Think about what a person sees while walking, not only the carefully framed view in a rendering.
Use a simple section drawing to place canopy, mid-level foliage, understory and ground cover. Show mature dimensions rather than newly installed sizes. A tree that looks modest in a schematic can eventually block an important view, shade an entire terrace or crowd a bridge. The Royal Botanic Garden Edinburgh and Kew Gardens offer useful ways to observe how visitors move through planted collections and how paths make changing plant scales legible. Their glasshouses are not direct models for every home or hotel, but they encourage careful attention to routes, climate zones and viewing distances.
Design the vertical experience
There is no requirement for every storey to have the same planting density. A bright upper landing might support a more sun-tolerant canopy, while the level below receives filtered light and benefits from a quieter, shade-adapted palette. The ground plane can be more robust, with room for maintenance and seasonal adjustment. Varying the planting in response to actual conditions makes the garden more convincing than repeating identical planters up the full height.
Look for connections that stitch levels together. A repeated material, a vertical trunk, a cascade of foliage or a family of planter forms can establish continuity. At the same time, small differences in texture and height help people understand where they are. Consider the garden from adjacent rooms as well: a generous view from a lounge or corridor can be as valuable as direct access to the atrium floor.
Coordinate safety and access early
Maintenance access belongs in the first spatial studies. Identify how staff will reach glazing, pruning points, drainage outlets, irrigation valves and high-level foliage. Aerial work platforms, fixed access systems or specialist horticultural methods need suitable clearances and a realistic operating plan. Keep maintenance movements separate from visitor routes where practical, especially in hotels or public buildings where the atrium remains occupied throughout the day.
Coordinate planting loads, containers and water with structural and building-services teams. Large planters can hold substantial wet weight; suspended planting adds its own fixing and irrigation considerations. Include containment, overflow management and a route to inspect connections. Consult the appropriate project professionals and local requirements rather than relying on a landscape concept drawing to resolve technical matters.
Make a section that can be tested
Before finalising finishes, review the design through simple scenarios: a family arriving with luggage, someone using a mobility aid, a maintenance worker replacing a plant, or a guest waiting quietly near the garden. Check that circulation remains generous, seating does not obstruct routes and planted edges are understandable by touch and sight. Model the mature plants and consider how pruning might alter the composition over time.
The best vertical atria do not demand attention at every moment. They create a reassuring background to daily life, punctuated by memorable views and changing light. When each level supports a real activity, the garden feels integrated with the building rather than inserted as a decorative centrepiece.
