Landscape Guidelines

Download the Stonehaven Landscape Guidelines   VISION
Stone Haven Estate is set against the slopes of Brakkekloof Mountain with views over Noordhoek towards the sea. The dwellings for the Estate should be designed and positioned in such a way that they and the development as a whole become an integral part of the natural and agricultural landscape. This will be promoted by the use of natural colours and materials, which blend into the existing environment. The dwellings should be structured to define courtyards or garden spaces that will create a sheltered external space, whilst optimizing the views over the valley. The landscape design shall form an integral part of the architectural design process and shall not be seen as an "add-on" once the building is complete. Gardens, courtyards, avenues, water features, terraces, pools, pergolas and fences shall be used to enrich and complement the interior spaces and shall inform the architectural design process and vice versa. The design of external spaces and the link between the land, water and built forms is seen as integral to the character and aesthetic success of the estate as a whole. 1. STORM WATER/DRAINAGE 1.1  Stormwater runoff is to be controlled in order to avoid soil erosion. All details of stormwater disposal including paving and landscaping are to be clearly stated in the building plans. 1.2  Pre-cast concrete channels will not be allowed. Where channels are required they shall be constructed in stone, brick or cobble. 1.3  Stormwater shall be dispersed in grassed or reeded channels / swales or be allowed to penetrate within detention areas / reed-beds before entering dams in lieu of being piped underground. 2. EXTERNAL/OUTDOOR LIGHTING 2.1 External lighting shall be kept to a minimum. Where required, lights should be fixed to walls or columns or should be restricted to garden up-lighters. Garden uplighters shall be CHITTENDEN NICKS de VILLIERS STONE HAVEN ESTATE landscape architecture, urban design, environmental planning February 2004
black. External lighting must be low level and unobtrusive. 2.2  Generally, roads shall not be lit and courtyards and parking areas shall be minimally lit and restricted to entrance porticoes where possible.

Paved courtyards shall be enriched by the use of attractive hard surfacing such as approved brick, sandstone gravel, stone and slate. 'Sleeper' pathways and timber log pathways and steps are acceptable. Timber decks, which do not protrude over building lines, and are constructed as close to the natural ground level as possible, are also acceptable. Gravel may be used as an alternative to hard paving. Grass blocks are not allowed. All paving materials and paving plans are to be approved by the Design Review Committee/estate developer or H.O.A. 6.1  The following brick colours are be acceptable: COROBRIK: Wheatstone Paver CRAMMIX: Sahara Sand Paver 6.2  The following concrete products will be acceptable: SMARTSTONE: Cobbles and pavers in sandstone colour PAVATILE: Cobbles and pavers in colour 157 REVELSTONE: Cobbles and pavers in sandstone colour OKAVANGO PAVING: Okavango Plaza 80mm exposed sandstone aggregate paver in sandstone colour.

ENVIRONMENTAL /SOFT LANDSCAPING CONTROLS 7.1 SITE CLEARING 7.1.1  No trees or vegetation outside the building area of each site may be removed without approval of the Architectural Review Committee. 7.1.2  Damage to trees and vegetation on any land unit will be subject to penalties in accordance with the Environmental Management Plan. 7.1.3  Damage to trees and vegetation on Common Property will be subject to penalties in accordance with the Environmental Management Plan. 7.2  PLANTING CHARACTER The planting theme is primarily indigenous, with the addition of traditional 'Cape' plants. With the exception of fully enclosed courtyards, all trees and shrubs shall be non-invasive. A list of proposed plants follows as a guide. No invasive alien or invasive exotic plants will be allowed anywhere on the estate. Shrubs and groundcovers shall be chosen in keeping with the style and character of the estate. The style may be loosely defined as indigenous and rustic. Climbing plants and creepers shall be encouraged to cover walls, create shade under pergolas and climb buildings to soften hard edges and surfaces. The use of informal hedges is encouraged. The use of 'tropical' plants such as palms, banana trees, Scheffleras, Phormiums, yuccas and/or Strelitzias is seen to be inappropriate. The use of plants indigenous specifically to the site is proposed. Generally, the style should be relatively informal. 7.3  SIDEWALK / ROADSIDE PLANTING Planting on roadsides or on sidewalks or embankments must be planted using shrubs and groundcovers chosen from the proposed list and must be planted to blend in with adjacent sidewalk areas. All roadside or sidewalk planting shall be irrigated by the homeowner by means of an automatic irrigation system.
