Contemporary gardens

Contemporary garden design is one of the most requested styles we work with across South West London and Surrey, and for good reason. When it is done well, it is among the most satisfying types of garden to live with: ordered without being rigid, easy to maintain without feeling empty, and capable of looking as strong in December as it does in June.

The appeal is partly visual and partly practical. Clean lines, strong geometry and a considered material palette create a sense of calm that is particularly valuable in urban and suburban settings where the garden is often the only genuinely quiet space a household has. The emphasis on structure over clutter means the garden reads well from inside the house as well as outside it. And a well-planted contemporary scheme, built around the right combination of evergreen structure and seasonal perennial interest, requires far less ongoing intervention than most other styles.

It is also a style that translates well across the range of properties Flourish works with most regularly. The Victorian and Edwardian terraces of Surbiton, Kingston and Twickenham benefit from a contemporary approach that respects the character of the house without mimicking its period. The larger detached gardens of Esher, Cobham and Thames Ditton suit bolder contemporary geometry with pleached screening and structural planted masses. The urban rear gardens of Richmond and Clapham are natural homes for the pared-back, high-quality material palette that contemporary design demands.

This guide covers everything you need to understand the contemporary garden style in the context of Surrey and South West London conditions – from the design principles and hard landscaping choices through to the soil preparation required on Surrey clay, the planting that delivers the best results, the maintenance the style realistically requires, and how the Flourish team approaches contemporary projects from first consultation to completed build.

What defines a contemporary garden

A contemporary garden is not simply a modern-looking garden. It is a garden built around a coherent set of design principles that prioritise structure, restraint and considered proportions above decoration and abundance.

The key characteristics are these. First, geometry: contemporary gardens use strong, deliberate lines – rectangular paving areas, defined lawn edges, raised beds with clean profiles, and structural planting in organised masses rather than mixed borders. Second, material quality: contemporary design relies on the inherent quality of surfaces rather than ornamentation. Large-format paving, precision-cut timber, rendered walls and powder-coated metal need to be specified and installed correctly because they are the garden rather than the backdrop to it. Third, a restrained planting palette: rather than the variety and abundance of cottage or naturalistic planting, contemporary gardens use a limited number of species repeated across the scheme in bold masses that read clearly from a distance and create rhythm and coherence throughout the year. Fourth, year-round structure: contemporary planting is chosen as much for its winter silhouette as its summer performance. A scheme that disappears in November has not solved the problem of how the garden looks from the kitchen window on a grey February morning.

These principles do not produce cold or sterile gardens. When they are applied well, with proper attention to planting texture, movement and seasonal change, contemporary gardens are genuinely beautiful and genuinely liveable spaces.

Contemporary gardens in the context of Surrey and South West London

The domestic architecture of the areas where Flourish works most frequently is a significant influence on how contemporary design is expressed. The red brick of Victorian Surbiton and Edwardian Kingston calls for a slightly warmer material palette than the rendered or painted facades of newer builds – warm grey porcelain, honey-toned sandstone or sawn granite rather than cold blue-grey formats. The generous rear gardens of Esher and Cobham allow for bolder structural moves: longer sight lines, deeper planted masses, and the kind of large-scale pleached screening that creates an enclosed outdoor room within an open plot.

The Surrey climate is broadly favourable for contemporary planting. The relatively mild winters of the KT and TW postcodes, moderated by the Thames and the urban heat island effect, allow a wider range of structural evergreens than most of the UK can reliably sustain. Pittosporum tenuifolium, Choisya ternata, Sarcococca species and Viburnum davidii all perform well in this area, providing the year-round structure that contemporary schemes depend upon.

Surrey's London Clay subsoil is the condition that requires the most careful attention. Heavy clay is fertile and moisture-retentive, which suits many contemporary planting choices well. The challenge is drainage. Large paved areas on clay must be designed with correct falls and, in many cases, sub-surface drainage to prevent water pooling at the base of walls or around planting beds. On sites where clay has been compacted during construction – common on newer housing developments across the KT postcodes – decompaction and organic matter incorporation before planting is essential for plants to establish well.

Hard landscaping and materials

The hard landscaping in a contemporary garden carries most of the design weight. It is worth spending the budget here before thinking about planting, because a poorly specified surface degrades every element around it while a high-quality one elevates everything placed on it.

Paving

Large-format paving reads best in contemporary design because it reduces the number of joints visible across the surface and creates a calmer, more resolved appearance. The most popular choices in the gardens Flourish builds across Surrey are as follows.

Porcelain paving in large formats – typically 900 x 600mm or 1200 x 600mm – offers exceptional durability, low maintenance and a clean, consistent surface. It is available in a wide range of finishes, from concrete-effect to natural stone replication, and the best quality products are convincing in both directions. It must be installed on a proper mortar bed on a compacted sub-base, and on clay soils a concrete sub-base rather than MOT Type 1 alone is advisable for large patio areas to prevent movement. Porcelain does not stain, frost is not a concern with proper external-grade products, and it requires virtually no maintenance beyond an annual clean.

Natural sandstone, particularly the warmer Indian sandstone tones such as Raj Green or Fossil Mint, suits the material palette of brick-built Surrey properties well and ages gracefully. It requires more maintenance than porcelain – sealing and periodic re-pointing – but the variation in natural stone gives warmth that no porcelain product quite replicates. Calibrated sandstone from reputable suppliers such as London Stone or Pavestone delivers consistent thickness for straightforward installation.

Sawn granite in grey or buff tones suits contemporary gardens with a harder edge, particularly where the property itself has a colder material palette. It is extremely durable and weathers well but is the most expensive natural stone option.

Edging and definition

The edges between surfaces are where contemporary design is made or unmade. Crisp edges between paving and lawn, between lawn and planted areas, and between gravel and planted beds define the geometry that gives the style its character. Cor-Ten steel edging, powder-coated aluminium, or sawn stone edging strips are the most widely used options. All require careful installation to maintain their line over time on clay soils, where movement must be accounted for.

Structures

Pergolas, screens and raised beds in contemporary gardens are typically built from architectural timber – hardwood such as Iroko or Accoya, or pressure-treated softwood with a clean profile – or from steel and powder-coated metal. Rendered or brick raised bed walls in a single, clean render finish suit most Surrey properties well and age better than timber in a high-moisture clay environment.

Soil preparation on Surrey clay

Surrey's London Clay requires preparation work before contemporary planting will establish and perform as intended. This is not a reason to avoid the style but it is a reason to plan and budget for it properly.

Where paved areas are being installed, the sub-base must be adequate for the load and for the clay conditions beneath it. On residential patios across our working area, a minimum 150mm compacted MOT Type 1 sub-base is standard, and on heavier clay or where drainage is poor, we recommend a concrete sub-base to prevent differential settlement.

Planting beds on clay benefit from decompaction to a minimum depth of 400mm, incorporation of coarse grit at a rate of approximately one part grit to three parts clay by volume, and the addition of good-quality topsoil or compost to improve structure. On sites where topsoil has been stripped or buried during construction – a frequent issue on newer developments – importing a quality topsoil is often more cost-effective in the long run than attempting to condition exhausted subsoil.

Drainage is a priority on any clay site where large areas of paving are being installed. Channel drains at the edges of paved areas, correctly set falls across the paving itself, and soakaways or connection to surface water drainage where permitted all contribute to a patio that performs well in wet conditions rather than flooding against the back of the house.

Planting for a contemporary garden on Surrey clay

The planting in a contemporary garden serves a different purpose from planting in naturalistic or cottage schemes. It is not about abundance or seasonal drama. It is about structure, repetition, texture and a quiet kind of interest that works across all twelve months. The species list below represents the plants that deliver those qualities most reliably in Surrey conditions, on clay-based soils, within the mild climate of the KT and TW postcodes.

Structural evergreen shrubs

These plants provide the permanent framework of the scheme and should be planted generously. They are the backbone that holds the garden together when everything else has died back.

Pittosporum tenuifolium – one of the most useful evergreen shrubs for contemporary gardens in South West London. Compact, dense, and available in a range of forms from the dark-leaved 'Tom Thumb' to the silver-variegated 'Silver Queen'. Reliably hardy in sheltered Surrey gardens and tolerant of clay soils with reasonable drainage.

Viburnum davidii – a low, spreading evergreen with deeply veined leaves that are striking at close range. The structural, horizontal habit suits contemporary planting edges particularly well. Tolerant of heavy clay and moderate shade.

Sarcococca confusa – a slow-growing, dense evergreen with intensely fragrant white flowers in late winter. Invaluable in contemporary schemes for its year-round structure and the fact that it flowers when almost nothing else does. Tolerant of deep shade and clay soils. Spreads gradually by suckering to form a solid mass over time.

Choisya ternata 'Sundance' – the golden-leaved form of Mexican orange blossom provides colour contrast in a green-dominated palette. Scented white flowers in May and again in autumn. Performs well in Surrey conditions with some shelter from cold east winds.

Ilex crenata 'Dark Green' – one of the most reliable Buxus alternatives for clipped structure in contemporary schemes, offering a fine-leaved, dense habit that clips cleanly and does not suffer from box blight. Hardy, tolerant of clay soils, and available in a range of trained forms.

Grasses and movement planting

Our detailed ornamental grasses guide covers the full range of species for Surrey conditions.

Ornamental grasses are indispensable in contemporary design. They provide movement, transparency and seasonal change in ways that no broadleaf shrub can replicate, and their winter seedheads and skeletons are among the most architecturally effective elements in the January garden.

Calamagrostis x acutiflora 'Karl Foerster' – the most reliable upright grass for contemporary schemes in Surrey. Produces stiff, architectural flower stems in June that persist well into winter. Fully deciduous but the dry stems remain standing and valuable. Tolerant of clay soils and moderate shade. Divides well every three to four years to maintain vigour.

Stipa gigantea – golden oats. A semi-evergreen grass with an upright base and dramatically tall, airy flower stems that shimmer in late spring and summer. Excellent as a specimen or in repeated groups. Requires a sunny position and reasonable drainage; on heavy clay, raising the planting level slightly helps.

Pennisetum alopecuroides – a compact, clump-forming grass with attractive bottlebrush flower heads from late summer through to November. The cultivar 'Hameln' is the most reliable in UK conditions. Benefits from a sunny position.

Miscanthus sinensis 'Gracillimus' – a tall, elegant grass with narrow silver-striped leaves and feathery plumes from September onwards. The plumes persist well into winter and are at their most beautiful when backlit by low winter sun. Tolerant of clay soils. Cut back hard in late February before new growth emerges.

Perennials for seasonal interest

A limited number of perennials, planted in bold masses rather than one-off specimens, provides the seasonal colour and interest that lifts the structural palette of evergreens and grasses.

Agapanthus 'Headbourne Hybrids' – hardy agapanthus for the Surrey climate, producing strap-like foliage and blue-purple flower heads from July to September. Works particularly well against pale stone paving. Requires a sunny position and reasonable drainage; in heavy clay, raising the bed is advisable.

Echinacea purpurea 'Magnus' – a robust, long-flowering perennial with large pink-purple daisy flowers from July through to September and structural seedheads that carry the scheme into winter. Fully hardy on Surrey clay. Benefits from a sunny position.

Rudbeckia fulgida var. sullivantii 'Goldsturm' – one of the most reliable late-season perennials for contemporary schemes. Bold yellow flowers from August to October and persistent seedheads through winter. Tolerant of clay soils and some shade. Spreads steadily to form effective ground cover.

Nepeta x faassenii 'Six Hills Giant' – catmint. Produces clouds of blue-purple flower spikes from May to October when cut back after the first flush. Invaluable as a softening edge plant against hard paving. Fully hardy and tolerant of Surrey clay.

Salvia nemorosa 'Caradonna' – a compact, upright salvia with intense violet-blue flower spikes on dark stems from May to July, with a second flush in September if cut back. Excellent massed in front of grasses or along paving edges.

Focal specimens and trees

For a full species guide and design advice, see our multi-stem trees blog.

Every contemporary garden benefits from one or more focal plants that anchor the scheme and provide height, seasonal interest or year-round form.

Amelanchier lamarckii – one of the most versatile small trees for contemporary gardens across Surrey. Spring blossom, summer foliage, vivid autumn colour and a clean branching habit in winter. Tolerant of clay soils. Available as a multi-stem form, which is particularly effective in contemporary planting.

Betula utilis var. jacquemontii 'Doorenbos' – the white-stemmed Himalayan birch is among the most elegant focal trees for contemporary schemes. The luminous white bark is at its most striking in winter when the canopy is bare. Tolerant of clay conditions. Best planted in groups of three for maximum impact.

Prunus serrula – the Tibetan cherry, grown primarily for its extraordinary polished mahogany bark that glows in winter light. A small, manageable tree that suits contemporary planting where a specimen feature is needed.

Phyllostachys aureosulcata f. spectabilis – a golden-stemmed bamboo for screening or focal use in contemporary schemes. The canes are a striking yellow with a green groove and achieve considerable height in Surrey conditions. Contains well in a deep rhizome barrier. Tolerant of clay soils and partial shade.

Climbers

Climbers are valuable in contemporary gardens for softening boundaries and structures without compromising the clean lines of the scheme.

Hydrangea anomala subsp. petiolaris – the climbing hydrangea is one of the most useful climbers for contemporary schemes. Self-clinging, tolerant of north and east-facing walls, and producing large white lacecap flowers in June against a backdrop of rich green foliage. Slow to establish but reliable once it takes hold. Tolerant of clay soils and shade.

Clematis armandii – an evergreen clematis with bold, leathery foliage and strongly scented white flowers in March and April. Provides year-round cover on a warm, sheltered fence or wall. Best in a south or west-facing position.

Rosa 'Compassion' – for contemporary schemes where a climbing rose is appropriate, 'Compassion' offers large, fragrant salmon-pink flowers from June to October on a well-branched framework. Less disease-prone than many climbers and more compatible with the clean material palette of a contemporary garden than highly vigorous species such as Rosa filipes 'Kiftsgate'.

Maintenance for a contemporary garden

Contemporary gardens are often chosen partly because they are perceived as low maintenance. This is broadly correct, but the reality is more nuanced. A contemporary garden requires less ongoing intervention than a cottage or naturalistic scheme, but it does require the right maintenance at the right time of year.

Grasses need cutting back hard in late February before new growth emerges. Calamagrostis and Miscanthus can be cut to approximately 10–15cm from the ground. Stipa gigantea is semi-evergreen and should be combed through rather than cut hard. Dividing grasses every three to four years maintains vigour and prevents the centre dying out.

Evergreen structure planting benefits from a light tidy in spring, removing any winter damage and cutting back any plants that have exceeded their intended footprint. Clipped forms of Ilex crenata or Pittosporum should be trimmed once or twice a year to maintain shape.

Perennials should be cut back in late autumn or early spring depending on whether winter structure is valued. In contemporary schemes, we generally recommend leaving seedheads standing through winter for their structural contribution and cutting back in late February alongside the grasses.

Paving benefits from an annual clean. Porcelain can be pressure-washed or treated with a proprietary hard surface cleaner. Natural stone should be treated with an appropriate stone cleaner and, on Indian sandstone in particular, resealed every two to three years to maintain appearance and prevent staining.

Edging should be checked annually for movement, particularly on clay soils where seasonal shrinkage and swelling can displace edging strips over time.

How Flourish designs and builds contemporary gardens

Our approach to a contemporary garden project begins with understanding the site and the people who will use it. Craig Davis BSc (Hons) Horticulture leads the initial consultation, assessing the soil conditions, the aspect, the existing levels and any drainage issues before design discussions begin. Getting the site assessment right is what allows the design to work in practice rather than on paper.

Eli Jacobacci, our in-house garden designer, develops the layout and planting scheme from the brief. For contemporary gardens, this means working through the geometry of the space carefully – how the levels will be resolved, where the key sightlines are, how the proportions of paved areas relate to planted areas and to the house. The planting scheme is developed alongside the layout rather than after it, because in contemporary design the structural plants are part of the architecture of the garden.

Our construction team then delivers the build. Hard landscaping on Surrey clay is something we approach with particular care – the sub-base specification, the drainage details and the edging installation all have a long-term impact on how the garden performs. Trevor brings 40 years of fencing and structural experience to the boundary and screening elements that define so many contemporary gardens.

Once the build is complete, Eli and Craig review the planting installation to ensure spacing, orientation and soil preparation are correct. We offer aftercare guidance as standard, and our maintenance team is available for ongoing seasonal visits for clients who want the garden to be maintained to the standard it was built to.
