HERBOTH’S BLICK NATURE ESTATE
Architectural Guidelines
1. INTRODUCTION
1.1 CONCEPT STATEMENT
The main objective of the development is to provide a high quality lifestyle for
residents to live within a secure wildlife estate with a high standard of
architecture. The purpose of the Building Controls is intended to be informative
rather than restrictive. The guidelines will permit innovative design expression
and encourage optimal use of orientation and site topography, whilst retaining the
benefits of overall harmony for the entire development through restrictions on
basic materials, fenestration and finishes, following broad guidelines within a
stylistic approach

These Architectural Guidelines establish the architectural character of the
scheme and are an addition to the by-laws of the Municipal Council as
appropriate at the time of submission, and National Building Regulations.
1.3 AMENDMENTS TO ARCHITECTURAL GUIDELINES
Herboth's Blick Nature Estate Home Owners’ Association reserves the right to
make minor adjustments and amendments to the design controls incorporated in
the Guidelines when deemed necessary, and only after having properly
investigated and substantiated the requested amendments. Any such
amendments granted by Herboth's Blick Nature Estate Home Owners’
Association shall be made prior to and remain subject to the approval of the
design by the Municipal Council as appropriate at the time of submission.
1.4 ARCHITECTS
Only professional Architects registered with the Namibian Council for Architects
and Quantity Surveyors, with a minimum of 5 years’ working experience, who will
hereafter be referred to as the “Design Architect” may be appointed for the

3.8 GENERAL LANDSCAPE GUIDELINES
In order to control the general landscape development on private property
to be a continuation of the wilderness, the following set of guidelines will
be applicable to every stand:
3.8.1 Intent
The purpose of the general landscape guidelines is to create an
integrated and responsive landscape with emphasis on nature, open
space and style that will be unique to Herboth’s Blick Nature Estate. It will
also create sensitivity and harmony between the private stands and the
communal open spaces as well as the streetscape. The guidelines
furthermore aim to preserve and enhance the natural open spaces,
minimise possible negative impacts whilst at the same time establish a
new, stylish and farm-type nature-based character to Herboth’s Blick
Nature Estate.
3.8.2 Preservation of existing trees
The development will at all cost preserve as many as possible of the
existing trees, in order to minimise any visual impacts and to preserve the
value and character of the site. However, any new tree planting must be
indigenous and as far as possible be local (endemic) species.
In order to control and minimise the area of tree clearing on individual
stands, the approach towards the preservation of trees on private
property will be that of a Building Envelope to be established for every
stand, within which the following will apply:
3.8.2.1 The principle will be that a maximum area consisting of the
house footprint area plus an additional area of maximum
5m wide outside the footprint, can be cleared for
construction;
3.8.2.2 Any tree outside this area must be preserved at all cost
unless it can be proven that a tree might be unstable and
can cause a potential danger for falling over;
3.8.2.3 This 5m wide zone is not allowed to encroach on the
building line area;
3.8.2.4 Any indigenous tree exceeding 1 metre in height, within the
building line area must also be preserved;
3.8.2.5 Trees within driveway, patio and pool areas can only be
cleared within an area equal to the minimum dimensions of
the structure plus 1m on either side (3m in the case of a
pool);
3.8.2.6 Each owner will be encouraged to plant at least 20 new
indigenous trees after completion of construction.
3.8.3 Plant species
The character of Herboth's Blick Nature Estate constitutes not only the
Bushveld feel but also in the architectural style as well as the specific
landscape architecture to be introduced. The landscaped vernacular will
fulfil a crucial role in the harmonious integration of the existing
environment and the new development. For this reason the use of plant
species on private property need to be controlled as follows:
3.8.3.1 The establishment of an indigenous, and as far as possible
endemic, plant community is encouraged throughout
Herboth's Blick Nature Estate;
3.8.3.2 No exotic or invader species are to be introduced;
3.8.3.3 Plant species are to enhance the character of the
landscape on common open spaces and street reserves
(refer to the general landscape plan). The following
species are preferred and may only be used within the
transition zone as described below:
The following species are preferred only these species may be
planted within the transition zone:

3.8.4 Landscape design
The integration of the landscape design of open spaces and street
reserves with that of private property is encouraged. The following
measures are to be applied in the landscape design of each stand:
3.8.4.1 Landscaping on private stands within the building line area,
must be treated as a transition zone between the
communal landscape and the private gardens. The design
guidelines need to be strictly adhered to within the building
line zone;
3.8.4.2 Homeowners are encouraged to enhance and to stay
within the framework of species and landscape character
of the estate;

3.8.4.6 No formal gardens, hedges, features or ornamental garden
structures will be allowed within the building line zone,
other than inside private gardens, so as to establish natural
areas that will enhance the communal landscape
appearance. The use of mass planting and simplicity in
design must dictate the garden layout in the transition
zone. Pot plants must match the style of the architecture of
the house.
