Accoya Decking with Zinc Terrace

Chesham Bois

Initially engaged to create a transitional space between the extension the clients had to their home, Karl created a garden with various zones that both complement and contrast.


Brushed Accoya Decking with Zinc Panels

Heavily brushed Accoya suspended over acid-etched zinc galvanised steel forms the decking structure at one end of the house.  In order to emphasise the detail within the timber, Karl chose wide deck boards secured with hidden fittings.  Over time this timber will weather to a silvery grey which will add a subtle contrast to the blue-grey of the steel.

The deck is framed with planting in varying shades of green purple and white to complement the existing Wisteria, and to offer a contrast to the grey tones of the deck and the steel edging.

Karl Harrison Said, “This deck is amazing.  It’s actually one of my favourite decks that I’ve ever built”


Natural Stone Steps and Patio

The transition from the back of the house to the lawn and the use of space off the extension were at the heart of the client’s brief.  After various iterations and multiple concept drawings, Karl came up with a design the clients were happy with.  The diverging angles created by the house and the fence led Karl to create something with a geometric design. This is complemented by the lines of the stone steps and the natural limestone paving; the geometry of both adding an extra dimension to the octagonal shape of the patio.

The leading edge of the patio is planted with tall grasses and fragrant shrubs to soften the drop to the adjacent garden.  While these offer varying shades of green to contrast against the grey limestone paving, the Osmanthus x burkwoodii also stimulates the senses with aromas reminiscent of honey apricot and peach.


Planting – Contrast and Combination

The planting in this garden covers five zones of varying sizes and shapes.  A small wild meadow surrounds a stand of Betula utilis var. jacquemontii at one end of the garden, while ferns and ground cover plants fill the smallest planting bed.

The two main planting areas are populated with plants of varying height texture colour and shape.  The primary colour is purple – the client’s favourite – with splashes of red white and yellow to add contrast.  Combinations of planting add interest with Lupin and Iris planted amongst tall grasses to add colour and catch the eye, while larger shrubs such as Hydrangea, and trees such as Cornus kousa var. Chinensis, add structure.
