Design Issues

Homes in the village are generally required to meet the Castle Hill Mountain Village Design Rules.

A number of existing home owners have contributed unofficial design suggestions (e.g. design considerations to cope with climatic extremes etc at Castle Hill) that new owners may like to consider.

Design Approval

New house designs must be approved by the Design Assessment Committee which consists of John Reid and a representative of the CHCA. This approval must be gained before submission of building plans to Selwyn District Council for consent.

To start the process of gaining approval from the Design Assessment Committee, please email a set of plans to  John Reid.

Please consider long term effects on shading and the view, for both your own section and that of your neighbours, when choosing your plantings.

Historically trees have been planted to play a large part in the development of an alpine character within the Village reserves.  However most of the quick growing exotic pines in the village are now classified as pests and are actively being phased out with native replacements.

Impacts of Trees

Favourable Adverse
Alpine appearance Blocking sun
Shelter from wind Shading
Softening lines Blocking views
Improved aesthetics Potential for damage to property
Shade in summer Wind funnelling
Increased Bird life in Village Frosting
Frost/Snow retention as part of winter beauty Fire potential
Play spaces for younger children

The trees in the Village are therefore being pro-actively managed to, where possible, maximize the favourable aspects but also minimize the adverse impacts.

Plants to avoid

Please be aware that certain plants now appear on the ECAN Canterbury Regional Pest Management Plan 2017-2037 which classifies the following introduced conifer tree as pests.

Introduced conifer trees
Bishops Pine Pinus muricata
Contorta (Lodgepole) Pine Pinus contorta
Corsican Pine Pinus nigra
Douglas Fir Pseudotsuga menziesii
European Larch Larix decidua
Maritime Pine Pinus pinaster
Mountain (& Dwarf Mountain) Pine Pinus mugo (& P. uncinata)
Ponderosa Pine Pinus ponderosa
Radiata Pine Pinus radiata
Scots Pine Pinus sylvestris

Please note also that Rowan, Silver Birch, Sycamore and Cotoneaster are also problematic due to their spreading abilities.

The T.E.R:R.A.I.N website offers an excellent list of plants to avoid as does Weedbusters.

Planting

Planting appears to work well if plants are planted in late spring with weekly irrigation and rabbit fencing – allow for growth of the plants with 500 mm diameter cages (minimum).

Broom

Broom control is required by Selwyn District Council/ECAN on empty sections, and can/will be enforced.
