17 London Garden Design Ideas: Create a Tranquil Oasis in the Heart of the City
We get it. Transforming an urban garden into a green slice of heaven is no small feat—especially in a bustling city like London. Gardens in the capital are 26% smaller than the national average, making them the smallest of any UK region. The typical garden for a London house is just 140 square metres, meaning space comes at a premium. This presents all kinds of challenges, from accessibility to limited shade.
While a tiny garden may need a little more thought and planning, with the right small London garden design ideas and a bit of creativity, it can be transformed into a practical and stylish outdoor space. Get inspired by these 15 London garden design ideas that will help you create a tranquil oasis in the heart of the big smoke. We’ll also share some practical tips for maintaining your London garden and furniture to ensure it remains a vibrant sanctuary within the confines of one of the world’s largest urban jungles.
20 London garden design ideas to maximise space
1. Use vertical gardening
Monterrey 2 Seat Rope Sofa Set Grey £1,599.00
Vertical gardening can be a game-changer when you live in the heart of the city. By growing your plants upwards on walls, fences or trellises, you can increase your greenery without sacrificing precious ground space. Plant climbing roses, ivy or even vegetables—like beans, tomatoes and cucumbers—that require less ground space and can be grown against poles or netting. You can enhance the aesthetic by hanging stylish pots or vertical planters to create your living wall.
2. Get multi-functional furniture
In small London gardens, every piece of furniture should serve more than one purpose.
Look for benches with built-in storage, tables that can extend for entertaining guests or foldable chairs that are easily tucked away when not in use. An ottoman that doubles as a storage box is a great way to hide your gardening tools while keeping the space tidy and providing additional seating for guests when needed.
3. Incorporate mirrors and reflective surfaces
Mirrors and reflective surfaces can create the illusion of space and depth and work wonders, making a small garden appear larger. Position large, rectangular mirrors horizontally behind benches to visually double your garden size. Alternatively, place a vertical oval mirror on your garden wall to reflect light and greenery, brightening dark corners.
Get creative and use mirrored panels on fences or walls to create a window effect, or add reflective garden ornaments to amplify the visual space and add a stylish touch.
4. Use clever storage solutions
Large Rattan Storage Box in Stone Grey £475.00
Keeping your smaller London garden organised is crucial to creating and maintaining a spacious feel. Get a helping hand from clever storage solutions like wall-mounted shelves, hidden storage compartments and garden tool racks to keep clutter at bay.
Stylish rattan console tables with glass tops that double up as storage boxes elevate your outdoor space and house pillows and seat covers without requiring extra outdoor storage. Vertical storage units also free up floor space, allowing you to enjoy a tidy and functional garden without feeling cramped.
5. Create a tropical feel in your London garden 
Stockholm Corner Dining Set with Firepit Table in Limestone - £2,999Escape to the tropics without leaving your home with vibrant colours and exotic plants like palm trees and ferns, which thrive in the UK’s milder climate. Add colourful outdoor cushions, rugs and lanterns alongside a small water feature or bamboo screen to enhance the exotic ambience and transform your urban garden into a lush, tropical paradise.
6. Create cosy seating areas
Turn even the smallest space into a charming retreat that exudes comfort. Use cosy cushions, soft throws and weather-resistant bistro, sofa and lounge sets to create an inviting nook that's a perfect spot for relaxation. If you're lucky enough to have a slightly larger garden, consider installing a smaller pergola or add a small table and parasol. These provide shade and shelter, making your seating area more comfortable and usable no matter what the British weather throws at you.
Take it one step further and add a fire pit or fairy lights to enhance the ambience and create a cosy area for relaxing and catching up with family and friends.
7. Have friends over for a BBQ
Napoleon Prestige Pro 500 Built-in Gas Grill - Propane - £2,819
You don’t have to miss out on the great British BBQ season just because you have a smaller London garden. Invest in a compact BBQ grill and create your very own outdoor kitchen setup with a small prep station, storage for utensils and ingredients, and a dedicated BBQ area.
Add outdoor seating that’s easily rearranged to accommodate your guests, and string lights to add a festive touch. You could also pot some herbs for decoration or use them to garnish dishes, making your garden the go-to spot for summer gatherings and sizzling weekend cookouts.
8. Create shade with a pergola or parasol
Luna U-Shape Outdoor Fabric Sofa Set with Coffee Table in Oyster Grey - £4,999
Adding a pergola or parasol can provide much-needed shade and create a comfortable outdoor seating area for lounging, dining or entertaining. Invest in a luxurious, state-of-the-art pergola with drop sides, LED lights and drainage systems and beautify it with climbing plants like wisteria or jasmine.
Parasols are incredibly versatile and can be moved to different areas, preventing summer days from becoming uncomfortable scorchers. Choose a traditional wooden parasol for understated elegance or a free-standing cantilever design for maximum shade and UV protection.
9. Turn your garden into a trendy and modern London hub
Panama Luxury Outdoor Large Corner Group Set in Latte - £3,799
Modernise your garden with sleek, contemporary design elements. Choose minimalist furniture with clean lines and any colour theme of your liking. Neutral colours help create a calm, tranquil atmosphere, while bright hues will add an infusion of energy.
Incorporate trendy features like an outdoor kitchen, stylish plant pots and geometric patterns as well as materials like metal, glass and concrete for a chic, urban look. Smart solar lighting, stylish outdoor heaters and tech gadgets like Bluetooth speakers can help complete your modern garden oasis.
10. Protect a rooftop garden from wind
PergoSTET 3m x 4m Rectangular Pergola with 3 Drop Sides and LED Lighting with Wood Effect - £4,299
Rooftop gardens can offer stunning city views but often face strong winds. Protect your plants using windbreaks, such as glass panels, trellises or tall planters filled with dense foliage. Make smart plant choices by choosing wind-resistant lavender, rosemary and ornamental grasses that can withstand the breezy British conditions. Securing, lightweight furniture and décor to prevent them from tipping over and smashing is also a good idea.
Creating sheltered areas with pergolas can also provide a wind-free zone for relaxing and entertaining.
11. Use container gardening for small spaces
Luna 8 Seat Outdoor Fabric Rectangular Ceramic Firepit Dining Set in Oyster Grey - £3,849
Container gardening is perfect for compact London spaces. Use pots and hanging baskets of all shapes and sizes to grow flowers, herbs and evergreen shrubs. These will make your garden visually more interesting and add depth and colour. Place your containers on patios, decks or on your lawn, balconies and window sills to make the most of any available space. Containers can be moved and rearranged, meaning you can easily change your garden’s design, simplifying garden maintenance.
12. Zen-out in a minimalist Japanese garden design
Bay Large Corner Group Set with 4 Waist Pillows and Teak Table in Latte - £3,999
When you live and work in the capital, sometimes there's nothing you want more than a quiet, calm space to drown out the busy streets and escape the towering skyscrapers. Embrace minimalist Japanese garden design to create a tranquil outdoor space in the heart of the city. You can do this by incorporating the core design principles of Japanese gardens, such as balance, asymmetry, enclosure and borrowed scenery. Remember to use clean lines, simple structures and natural elements like rocks, gravel and bamboo.
Many Japanese gardens have water features, like a koi pond or stone basin, to enhance the zen atmosphere. Add low-maintenance greenery like moss, ferns and beautiful bonsai trees for the perfect escape from the urban hustle.
13. Try tiered planting
For small or sloped gardens, using tiered planting is a great opportunity to unleash your creativity and experiment with various herb, flower and plant combinations. It also provides depth and layers, making the space appear larger and more dynamic.
To create different levels for your plants, use raised beds, plant shelves or a rustic wooden ladder painted in a colour that matches your garden's aesthetic.
14. Create a green rooftop oasis
Julia 3 Seat Sofa Set in Volga Grey - £5,265
A lack of soil doesn’t need to be a barrier to spending time outdoors. Instead, transform an unused rooftop into a lush green oasis that contributes to biodiversity and provides a private retreat. A rooftop garden can transform your lifestyle by increasing your living space. Use lightweight containers and soil to reduce the weight on your roof and grow a wide range of plants, from flowers to small trees and shrubs.
Add a small sofa and side table to enjoy the views, alongside colourful cushions and lanterns to draw people together and enjoy evening gatherings while watching the sunset.
15. Add ambience with outdoor lighting
Outdoor lighting is a simple and inexpensive way to dramatically transform the atmosphere of your city garden. Use magical fairy lights, eco-friendly solar lanterns and energy-efficient LED lights to illuminate pathways and socialising areas. By strategically placing lights, you can ensure your garden stays warm and welcoming even when it turns dark. This transforms it into the perfect spot for al fresco dining, entertaining or simply relaxing under the stars.
16. Add features of Mediterranean garden design

17. Enjoy your garden year-round with heating or a fire pit
Kalama 8 Seat Rectangular Teak Firepit Dining Set in Latte - £3,549
Make the most of your garden throughout the year by incorporating heating solutions like a fire pit or an outdoor heater.
Providing warmth and a focal point for gatherings, a fire pit is guaranteed to create an enchanting atmosphere perfect for chilly evenings.

Once you've chosen your heat source, arrange seating around your chosen heater with blankets and an outdoor rug to create the ultimate cosy social area.
Tips for maintaining a London garden

Maintaining a garden in an urban environment like London comes with its own set of unique challenges. But not anymore! Follow our practical tips to help you keep your garden looking lush and vibrant year-round.
Pruning and trimming
Regular pruning and trimming are essential for promoting healthy plant growth and keeping your garden tidy. Remove dead or defective branches and plants to prevent the spread of pests and disease and trim back overgrown plants to maintain their shape and encourage new growth.
Pest control
Due to dense planting and limited space, city gardens can be susceptible to pests, so keep an eye out for common urban pests like aphids, slugs and snails. Use natural pest control methods such as neem oil as an organic insecticide or set up beer traps for slugs, but avoid chemical pesticides, which can harm the environment.
Seasonal care
Adapting to each season in the capital is crucial for maintaining plants and ensuring your outdoor space and furniture look their best year-round.
Spring: Focus on planting, nurturing and feeding your plants with organic fertilisers to give them the boost of energy they need to grow and bloom.
Summer: Ensuring your plants are regularly watered is essential throughout the summer months, especially during dry spells.
Autumn: This is the time to get organised for the season ahead. Clean up fallen leaves, prune your plants and prepare them for the upcoming winter season.
Winter: Protect your plants from frost with covers or move potted plants indoors.
Maintaining garden furniture is essential for keeping your outdoor space inviting, along with plant care. Luckily, Harbour Lifestyle’s cleaning and care products can keep your furniture looking as good as new. Invest in furniture covers to protect against the elements, and use storage bags and boxes to keep cushions and accessories safe and dry during the colder months.
