In the heart of London, outdoor space is a luxury, but even the smallest balcony, courtyard, or shaded patio can be transformed into a vibrant, stylish garden with the right design approach. As we step into the second half of 2025, small urban gardens are becoming multi-functional extensions of indoor living, designed with sustainability, serenity, and creativity in mind.
Whether you’re starting from scratch or reimagining a tired terrace, these urban garden design ideas will help you make the most of your space, no matter how compact.
From Grey to Green: Why Urban Garden Design Matters
In densely built-up areas, gardens are often tucked into awkward corners or hemmed in by surrounding buildings. These limitations present exciting opportunities for thoughtful, layered design. Instead of viewing your small outdoor space as a constraint, 2025 trends encourage us to see it as a canvas.
Today’s urban gardens are less about manicured lawns and more about micro-jungles, curated planters, vertical design, and multi-sensory zones that bring joy and biodiversity to even the most shaded corners of the city.

10 Small Urban Garden Ideas For Your City Garden
1: Design for Shade – Working With Urban Light Levels
One of the biggest challenges in London gardens is managing light, or lack thereof. Surrounded by tall buildings, many urban gardens experience partial to full shade throughout the day. But this doesn’t mean your garden has to be dull.
Create an enchanting retreat, featuring plants like hostas, ferns, and rhododendrons, all thriving in low-light conditions. This style creates a naturalistic, low-maintenance space that flourishes in shade. Try this:
- Layered planting with ferns, hostas, heucheras, and hydrangeas to create structure and interest.
- Pale surfaces (like light gravel or painted walls) to reflect and amplify natural light.
- Mirrors and gloss-finish pots to bounce light into darker corners.
- Shade sails or parasols that filter direct sun in exposed areas while adding privacy.
Low light? No problem. At Boma, we stock a wide selection of plants that thrive in low-light environments, perfect for north-facing patios and overlooked courtyards. Watch the video above for inspiration or visit us for expert advice from our in-store team.
2: Cottage Garden Design
The Cottage Garden style showcases an exquisite blend of soft textures and romantic blooms, including magnolia, viburnum, clematis, foxgloves, roses, and lavender. This classic look feels both wild and intentional: perfect for adding charm and colour to urban courtyards or terraces. Try this:
- Mix tall perennials like foxgloves and delphiniums with lower-growing ground cover.
- Add vintage-style planters or painted pots to enhance the nostalgic aesthetic.
- Use climbing plants like clematis or rambling roses to soften walls and fencing.

3: Colour & Texture in Small Spaces
Bold colour and texture can bring even the most compact city garden to life. In 2025, the trend is to treat your outdoor space like an indoor room, with colour-blocking, zoned areas, and statement accessories like container gardens. For added colour and texture, we recommend that you:
- Use a cohesive colour palette: blues and greens for calm; terracottas and golds for warmth.
- Mix smooth concrete or composite decking with textured planting like grasses, lavender, and ivy.
- Add a pop of colour with colourful glazed planters or vibrant foliage plants like coleus or Japanese maple.
4: Tropical Garden Design
Immerse yourself in an exotic garden, where every element brings drama, texture, and bold colour. Tropical gardens work beautifully in sheltered urban gardens and patios, creating the sense of a lush retreat with minimal space. To achieve this effect, you can:
- Combine structural plants like tree ferns, palms, and banana plants.
- Include vibrant blooms like cannas, hibiscus, or crocosmia for contrast.
- Use large ceramic or terracotta pots to anchor key specimens.
- Incorporate warm-toned gravel, decked pathways, or bamboo screens to enhance the tropical feel.
5: Vertical Gardening – Grow Up, Not Out
When horizontal space is limited, go vertical. Living walls, hanging baskets, and tiered shelving are perfect for bringing life to bare walls and fences without taking up valuable floor space. Perfect for balconies or a London roof terrace. Ideas to try:
- Wall-mounted planters, hanging baskets or trellis systems with climbers and trailing ivy, jasmine, or herbs.
- Repurposed ladders as plant stands.
- Stackable or modular containers that allow you to grow multiple plants in a small footprint.
Don’t forget that Boma’s Plant Potting Service can customise your vertical containers with beautiful, healthy plants selected for your light and style needs.
6: Mediterranean Garden Style
A Mediterranean garden brings the sun-drenched calm of the coast to the city, with drought-tolerant plants, sculptural trees, and fragrant herbs that thrive in pots or raised beds.
Try this:
- Plant lavender, rosemary, thyme, and oregano in terracotta pots.
- Include olive trees or cypress for structure and drama.
- Use light paving or gravel to reflect heat and brighten the space.
- Add a café table and chairs for that Mediterranean al fresco moment.
7: Multi-Use Micro Zones – Your Garden, Your Way
Urban garden design in 2025 is all about multifunctionality. Your garden might be your morning coffee spot, your evening reading nook, and your space to entertain friends, all in one.
Consider:
- Foldaway furniture that maximises usable space.
- A small water feature or fire bowl as a calming focal point.
- Built-in benches with hidden storage for tools and cushions.
- Outdoor rugs and solar lighting for all-day use and ambiance.
Pair practicality with beauty by integrating seating areas among tall grasses, flowering perennials, or aromatic herb collections.
8: Formal Contemporary Garden Style
A Formal Contemporary Garden is all about clean lines, contrast, and elegant simplicity. In small spaces, this style maximises impact by combining sculptural planting with smart materials and symmetry. Try this:
- Use box hedging, pleached hornbeam, or silver birch to introduce structure.
- Repeat plantings in a limited colour palette (think white, green, and soft purples) for cohesion.
- Include raised beds or planters in concrete, slate, or metal for a sleek finish.
- Position a focal point, like a modern water feature or sculptural pot, for visual interest.
Boma’s Garden Makeover Service can help you execute this minimalist yet impactful style with a range of refined plant choices.
9: Sustainability & Local Sourcing
Eco-conscious design is a leading trend for 2025. This means using reclaimed materials, planting for pollinators, and choosing suppliers who prioritise sustainability.
At Boma Garden Centre, we pride ourselves on offering locally sourced plants, peat-free compost, and design advice that supports biodiversity, right here in London.
10: Wild-life Sanctuary Garden
A Wildlife Sanctuary Garden turns your city space into a haven for bees, butterflies, and birds, while still looking beautiful. It's a rewarding, nature-first design that changes with the seasons. Here's how you can design your urban and balcony gardens to better support wildlife:
- Choose nectar-rich plants like lavender, buddleja, echinacea, and foxgloves.
- Incorporate native shrubs, climbing ivy, and grasses for shelter and texture.
- Include a bird bath, insect hotel, or log pile to support biodiversity.
- Avoid pesticides and go peat-free to make your space genuinely wildlife-friendly.
