Materials Useage

 

Unsuitable materials

The following materials are unsuitable in a Conservation Area:

· Cement tiles (Victorian profile corrugated iron or fibre cement roof slates are more acceptable).

· Clay tiles (except to replace or to use in association with existing clay tile roofs).

· Fibre cement roof sheets (except Victorian profile).

· Un-plastered concrete block.

· Artificial stone of any kind.

· Face brick.

· Exposed concrete of any kind.

· Unpainted Aluminium or steel windows or doors.

· Unpainted or varnished windows, doors, and garage doors (i.e. paint all exposed woodwork unless the original timber work is a hardwood such as teak and was never painted).

· Precast concrete fences. 14

· Precast concrete garages.

· Fibreglass sheeting.

Roofs

Scale, proportions, bulk, massing and levels of detail of roofs need to be consistent with the existing buildings in the street and reinforce the historic precedent of the Heritage Area. A key element unifying Simon's Town is the pattern of double pitched roofs with verandas and lean-to additions and a limited usage of materials and colours. This pattern is to be followed in new buildings.

Guidelines

Roofs are to be double-pitched, minimum 25 degrees and maximum 40 degrees.

If wider sections than 6 metres are required (Section 5.5) lean-to additions must be used. Roof pitches can range from 5 degrees to 15 degrees.

Lean-to elements should be subsidiary to its main pitched roof.

Different kinds of roofs could have different materials. For example the main roof could be slate and the verandah could be corrugated iron.

Simple gabled or hipped ends to roofs are to be used.

Roofs must be of Victorian profile painted corrugated sheeting or of slate or fibre cement shingle.

Colours are to be in the grey and black range.

Flat roofs can be used if screened by a parapet. A limited range of traditional roofing materials has been used, typically painted corrugated iron or slate.

Double pitch with lean - to Lean- to's are subsidiary elements Dormers max. ¼ of roof area

Retain the original pitch of the roof.

Use conventional geometry to articulate the roof.

Retain any historic detail present in your roof construction.

Roof parapets are an important feature of early Simon's Town. Replacement with overhanging eaves destroys the historical fabric.

Use corrugated iron in Victorian profile.

Choose gutters with profiles as close as possible to those found in historic buildings.

Retain any chimneys.

Walls

Walls in Simon's Town are mostly of plastered and light painted masonry although stone was widely used for plinths and basement levels. With most sites being steeply sloping, a stone-faced basement plinth can reduce the impression of height. Dark coloured rough plaster can achieve the same effect.

Guidelines:

Walls are to be painted and plastered masonry.

Painted shiplap boarding is allowed for subsidiary elements.

Natural stone may be used for plinths.

 

 

Doors and Windows

Windows and doors have predominantly vertical proportions in the conservation area despite a wide
variation in architectural fashions. This element creates visual unity and should be reflected in new design.
Painted wood joinery is traditional in the conservation area. New materials such as aluminium can be used
but should be powder coated.

Guidelines:

Vertically proportioned openings should be used.

Large openings such as sliding doors should be set back from the façade by at least 1,5 metres or screened by verandas or pergolas.

Painted wood joinery is preferred but contemporary materials may be used if coated or painted.

Consistency in fenestration must be maintained.

Corner windows are not allowed, unless provided with a min. 100mm x 100mm corner post.

Large openings set back 1.5m
Alternative set back with pergola
Vertically proportioned openings.

Terraces and Plinths

The visual impact of poorly stabilized slopes and excessively high or long retaining walls is of concern.

Guidelines:

Exposed cut and fill slopes are to be stabilised with dry pack stone walls and vegetation.

Retaining walls must not exceed 2 meters in height and 10 meters in length.

Gabion retaining systems, without stepping or with gabions back a maximum of 50mm, may be used but are also not to exceed 2 meters in height and 10 meters in length.

Balconies and Verandahs

Many buildings in Heritage Ares have balconies and verandahs. These areas are designed as private outdoor spaces that are protected from the weather and from which views and fresh air can be enjoyed. They are regarded as important design elements with specific characteristics that make them different from the rest of the building. The enclosure of balconies and verandahs is generally not supported as this has a negative impact on the identified character of the building and Heritage Area. If enclosure is necessary, the following points should be followed:

Guidelines:

The enclosure should be as lightweight and transparent as possible, for example timber or metal frames with glass infill panels to reflect that it was an 'open' space

The new enclosed spaces should be designed as general living spaces such as living rooms or studies. These spaces are more suited to lightweight, transparent enclosures than bathrooms or bedrooms that require more privacy.

The frames and glazing of the enclosure should be designed so that they can be fitted behind the existing structure. Enclosures can be recessed to let the original stoep predominate.

The frames used for the enclosure should match the materials of the windows of the historic structure.

Complex designs and structures that enclose a verandah at awkward angles should be avoided.

Radio and TV, Solar Panels, Telephone and Electrical Services, Satellite Dishes, Lift Shafts, Funiculars, Cell & Radio Masts and Wind Turbines

These elements detract from the simple clean lines of the building forms and must be as inconspicuous as possible.

Guidelines:

All such electronic devices must be carefully placed in relation to the form of the building.

Solar panels must be flush with the roof and as inconspicuous as possible.

Telephone and electrical cables must be underground and built into the building.

Lift shafts may not project above the roof line.

Service and rainwater pipes

Guidelines:

Water supply and drainage pipes must be fully concealed.

Rainwater downpipes must be carefully placed and finished to tone in with walls.

Chimneys

 

Guidelines:

Only painted and plastered masonry or stone faced chimneys are permitted.

Electronics etc. to be inconspicuous
Plumbing to be concealed
Taditional roofscape with chimneys

 

Garage Doors

Guidelines:

Garage doors in Heritage Areas are generally single doors. Double garages should have two single doors with a masonry pillar between.

Doors are usually made of timber and painted. Powder or epoxy coated aluminium doors in an appropriate colour could also be used.

Traditional garage doors often had glass panels in the top half. A contemporary interpretation of this is appropriate.

The door should have either vertical or horizontal divisions, depending on the existing garage doors on the street. Diagonal divisions should be avoided.

Existing parapet walls on garages in the area could provide ideas for the new garage.

For public safety, garage doors are not allowed to open onto the pavement.

Driveway and Carport Gates

Gates in Heritage Areas are generally cast iron or timber and are well detailed. Contemporary interpretations of this traditional level of detail enhances the quality of the gate.

Guidelines:

Existing and original gates with distinctive historic character should be repaired or remade to match existing gates wherever possible.

Gates should be visually permeable to retain a visual link between the street and house.

Driveway gates should be compatible with pedestrian gates in their materials, design and character.

Gates may not open outward over the pavement.

Fences and Boundary Walls

Guidelines:

Retain old garden walls and hedges.

Use a suitable material for the garden walls and fences. Avoid un-plastered brick, pre-cast concrete or razor wire.

Keep the walls on the front street boundary low.

Boundary walls must respect their design context.

Boundary walls to be articulated (not flat).
