Quick Answer
Garden design ideas for large gardens in Oxfordshire and Buckinghamshire: divide the garden into zones (formal, informal, wild), use structure (hedges, paths, trees) to define spaces, choose plants suited to the soil (chalk or clay), create focal points (statue, water, specimen tree), and plan for year-round interest. A well-designed large garden in the Chilterns combines formal structure with naturalistic planting.
Why Large Gardens Need Design
A large garden without a design is just a field with a fence around it. The same garden, with a clear design, becomes a series of distinct spaces each with its own character. Design is what makes a large garden feel manageable, usable and beautiful.
In the Chilterns, large gardens range from 0.5 to 5 acres, often on sloping ground, with mixed soil (chalk on the hills, clay in the vale) and mature trees. The design challenge is to create a garden that feels cohesive despite its size, suits the local conditions, and works for the owner's lifestyle. This guide gives design ideas that work specifically for large gardens in Oxfordshire and Buckinghamshire.
The Zoned Approach
The best way to design a large garden is to divide it into zones. Each zone has a different purpose and character, but they all connect through paths, views and structure.
- Zone 1: Formal garden near the house. Patio, lawn, borders. The most maintained part of the garden.
- Zone 2: Family garden. Lawn, vegetable garden, play area. Functional and durable.
- Zone 3: Ornamental garden. Mixed borders, specimen trees, garden room. The decorative heart of the garden.
- Zone 4: Wild garden. Meadow, orchard, woodland. Low maintenance, high wildlife value.

Structure: The Bones of the Garden
Structure is what holds a large garden together. Without structure, a large garden looks like a random collection of plants. With structure, it looks designed.
Hedges
Hedges define spaces in a large garden. Use them to:
- Separate zones
- Screen ugly views
- Provide windbreaks
- Create garden rooms
Choose beech or yew for chalk soils, hornbeam for clay. See our hedging guide.
Paths
Paths connect the zones and lead the eye. Use different materials for different zones:
- Stone paving near the house
- Gravel for informal paths
- Grass for wild areas
- Bark for woodland paths
Trees
Trees provide structure and scale in a large garden. Plant:
- Specimen trees at focal points (oak, beech, rowan, ornamental cherry)
- Avenue trees along drives and main paths (lime, beech, hornbeam)
- Orchard trees in the wild garden (apple, pear, plum)
- Woodland edge at the boundary (native mix)
Focal Points
Every zone needs a focal point, something that draws the eye and gives the space a purpose. Focal points can be:
- A specimen tree (e.g. a mature oak in the lawn)
- A statue or sculpture
- A water feature (pond, fountain, rill)
- A garden building (summerhouse, gazebo, pavilion)
- A view (a gap in the hedge framing a view of the countryside)
- A bench at the end of a path

Planting Schemes for Large Gardens
Formal Borders
Near the house, plant formal borders with a mix of shrubs and perennials. Choose reliable plants that look good for months:
- Roses, flowering shrubs for months
- Lavender, evergreen, scented, drought-tolerant
- Hardy geraniums, long-flowering ground cover
- Alliums, dramatic flowers in late spring
Naturalistic Planting
In the middle zones, use naturalistic planting with grasses and perennials. This style looks good year after year with minimal maintenance:
- Stipa tenuissima, soft, flowing grass
- Verbena bonariensis, tall, airy
- Echinacea, pink daisy flowers
- Sedum, late flowers for bees
Wildflower Meadow
In the wild garden, plant a wildflower meadow. This is the lowest maintenance option and supports the most wildlife. See our wildflower guide.
Orchard
A small orchard (5 to 10 trees) is a beautiful feature in a large garden. Choose heritage varieties on semi-dwarfing rootstocks (M26 for apples). Plant in winter, 5 metres apart.
Designing for the Chilterns
Chiltern gardens have specific conditions that influence design:
- Chalk soil: choose Mediterranean plants, herbs, drought-tolerant perennials. See our chalk soil guide.
- Clay soil: choose shrubs, roses, perennials that tolerate wet winters and dry summers.
- Sloping ground: use terraces, retaining walls, and steps to create usable spaces.
- Mature trees: design around them, do not remove them. They add value.
- Views: frame the best views, screen the worst.
Cost of Designing a Large Garden
| Item | Cost |
|---|---|
| Garden design plan (1 acre) | 1,500-4,000 pounds |
| Hedges (50m, planted) | 750-2,500 pounds |
| Paths (50m, gravel) | 1,000-2,500 pounds |
| Patios (50 sqm, sandstone) | 3,000-6,000 pounds |
| Trees (5 specimen trees) | 500-2,500 pounds |
| Borders (200 sqm, planted) | 2,000-6,000 pounds |
| Lawn (500 sqm, seeded) | 500-1,500 pounds |
| Garden building (summerhouse) | 2,000-8,000 pounds |
Total for a large garden design and implementation: 15,000 to 50,000 pounds. See our garden design service and Chiltern Garden Design Plan PDF guides.
Common Mistakes
- Not having a design. A large garden without a design is just a field. Get a design before you start.
- Fighting the soil. Acid-lovers die on chalk. Match plants to your soil.
- Not using structure. Without hedges, paths and trees, a large garden looks random.
- Over-planting. Plants need space to grow. A garden that looks full in year 1 will be a jungle in year 3.
- Not planning for maintenance. A high-maintenance design is a burden. Plan for the time you actually have.
Frequently Asked Questions
Do I need a garden designer for a large garden?
Yes, almost certainly. A designer saves money by avoiding mistakes and creates a cohesive plan. See our garden design service.
How long does it take to design and build a large garden?
3 to 12 months for the design and construction, plus 2 to 5 years for the plants to establish.
Should I phase the work?
Yes. Phasing spreads the cost and lets you see how each phase looks before starting the next.

Mature gardens require a different approach from newly landscaped gardens. Preserve established specimens wherever possible, as they provide instant structure and maturity that cannot be bought.
