Yes—my top recommendation is a modular tall urban planter box around 1.2–1.5 m high with an integrated trellis or removable privacy panel. This design gives you an instant screen while still leaving room for evergreen plants to add softness and extra height. For a balcony, choose a fiberstone or GRP planter with a slim footprint, because it looks like concrete but is much lighter and easier to move. For a patio or rooftop, a powder-coated aluminum or corten steel planter is a strong, weather-resistant option; add a root barrier and use contained bamboo, ornamental grasses, or climbing vines to reach 1.7–2 m for standing privacy.
If you want the planter itself to do most of the screening, look for a model at least 1.4 m tall and 40–50 cm deep. A 1.4 m planter can screen seated sightlines, while a 1.7–1.8 m planter with plants works better for standing privacy. Check drainage, wind anchors, and weight limits before buying—especially on balconies. Good choices include a tall slatted-wood planter with a built-in screen, a fiberstone planter with a trellis, or a commercial-style aluminum planter with a clipped evergreen hedge. Avoid heavy soil-filled units on lightweight balconies, and use drip trays or irrigation to keep plants healthy without staining the surface.
