Moroccan garden kick-off

20170511_152203Construction has started on Insite’s Moroccan-inspired courtyard in Sydney’s eastern suburbs. Wall realigned, pots bought and ceramic tiles going down.

Bare palm trunks and other verticals

Lots of people have reservations about use of palms in their gardens, saying that “all the action happens at the top” and the bare trunks are an eyesore.

One solution is bromeliads.

In your next garden makeover, consider training a massed groundcover of bromeliads up that lonely palm trunk. It’ll be a beautiful eye-catching feature of your garden.

Another alternative for bare vertical elements in your garden is Sweet Peas. Often grown on a trellis or fence, consider fastening some chicken mesh to a post or pillar (in a sunny spot) and growing Sweet Peas up it. They are gorgeous.

Residential design – 5 tips for getting the most out of your Landscape Architect

There are many reasons to engage a landscape architect to prepare a design for the grounds of your house. The most likely is either that your local Council requires you to have one as part of your development application (DA) / construction certificate (CC) application or that you would just like to add beauty, utility and value to your property with a revitalisation of the garden.

If you plan to put in a substantive development application to Council, it’s likely that they will require a landscape plan to be submitted at the DA stage. For smaller development proposals, a landscape plan may only need to be prepared at the CC stage – a requirement that is often highlighted in a condition of consent approval.

Whatever your reason for getting a landscape plan done for your residence, here are 5 things to remember –

1. Ideas and inspiration. Your landscape architect is going to ask you questions about ideas and requirements you have for the grounds of your property. In addition to coming to terms with the actual brief of the job, they’ll likely want to know things like how you imagine using your property’s outdoor spaces, your mindset about plants and gardens, what stylistic things you are attracted to and whether you like formality or things being a bit rough around the edges. Take a bit of time to think about the above points before you meet your landscape architect – this preparation will help both to guide the design and to ensure that your needs and likes are met.

2. Input and feedback. After giving them your brief, your landscape architect will (if they haven’t already done so) analyse the site and other requirements and then formulate a concept plan for your property. They would then meet with you to present this concept. This is very important, as it provides the opportunity for you to be part of the design process, understand the outcomes of the scheme and tweak it, if required. Changes to a concept plan might eventuate because of ideas you’ve had since your original consultation or because of previously unconsidered matters that arise based on the landscape architect’s presentation. Ideally, you’d have another design discussion with your landscape architect prior to the finalisation of the scheme.

3. Grab the opportunity. If you need to engage a landscape architect as part of a DA or CC submission, I recommend you think of their engagement and the plan they produce as more than just a quick ‘box ticking’ exercise for your local Council. Instead, use the opportunity of the landscape architect’s engagement to have meetings with them and provide your own input and ideas (as above). The aesthetic and functional outcomes for your property will be all the better for landscape planning at the earliest stages of your development thinking.

4. Research your neighbourhood. I encourage clients, as do local Councils, to think about their properties as part of their environs. Regularly in residential design, allotments are treated like islands, with little stylistic reference to neighbouring lots or the streetscape. A good landscape architect, with reference to Council planning documents, will consider things like predominant garden styles in your immediate neighbourhood, mature tree species near your site and matters like how your front fencing selection might visually impact a streetscape.

5. Have a starting point. Provide your landscape architect with a detailed site survey plan. As with architectural design, having an accurate base plan to work from is vital. A detailed survey plan essentially includes the next level up of information from a survey contained in a property transfer. The detailed survey plan would have things like existing trees, paths, service lines and levels information plotted onto it.

One thing you must know before starting your next development application

If you’re undertaking a substantial modification to your house or proposing to knock it down and rebuild, you’ll need to submit a development application or similar approval application to Council.

As part of the development assessment process, Council or the private certifier will look at the floor space ratio (FSR) of the application – the ratio of a building’s total floor area to the size of the land upon which it is built. They will check to make sure that the development is in compliance with FSR controls and assorted other building controls that relate to that lot.

Generally speaking, the total floor area includes the internal area of all habitable rooms across every level of a building, but does not include open terraces or balconies.

An allied matter to FSRs is that a certain percentage of a site must be landscaped area.

Different Councils have different regulations regarding landscape area percentages, and these percentages also vary for the type of development being proposed.

An important site planning aspect to look out for in the wording of Council policies for landscape area percentages is whether the percentages they stipulate are just for ‘landscape area’ (which may be able to include hard paved areas and pools) or if they say, for example, ‘deep soil landscape area’ (which are areas that must be able to be planted).

For example, Lane Cove Council states that:

“For most types of development in Lane Cove, a percentage of the total site area is required to be ‘landscaped areas’. The ‘landscaped areas’ includes private open space and swimming pools, but does not include paved areas such as driveways……”,

……..but one of their charts – below – expresses ‘landscaped area’ as being ‘deep soil’ only.

Sutherland Council states that:

“The required landscape area of a site can be constrained by a control specifying the minimum required landscaped area defined as a percentage of the total site area”.

 Their zonal chart – below – just describes ‘landscape area’, without referring to ‘deep soil’ plantable area.

Make sure your architect or project manager is aware of the landscape space controls that relate to your property. If in doubt about Council’s terminology for inclusions and exclusions within a minimum percentage figure, check with Council’s landscape officer.

WHAT NOT TO DO WITH YOUR GARDEN BETWEEN DA AND CC

If you propose a development on your land, most local Councils will require a landscape plan to be submitted as part of the development application (DA) documentation.

A good DA landscape plan will not only propose well-considered new landscape treatments for the grounds of a property, but also record existing mature specimens and any other plantings deemed worthy of retention. The incorporation of recommendations for existing plantings on a site, at DA stage, is important. It shows Council and/or the private certifier that building works have not been proposed in isolation of their surrounds. It also shows that an owner or developer understands the intent of guidelines in Council local environmental plans (LEPs) and development control plans (DCPs), as well as the aim of a Council landscape code and tree preservation order.

When a DA is approved, it will normally come with a series of conditions of consent – some of which will relate to landscape matters of the site. A DA landscape plan (and for that matter the surveyor’s and architect’s plans) needs to show mature plantings that exist on an allotment. Even if such plans didn’t, Council’s consent document would still list and provide restrictions / approvals for such specimens. Key specimens will be shown in Council tables under such headings as ‘plants to be retained’, ‘plants which can be transplanted’ and ‘plants which can be removed’. These determinations are hopefully in accordance with suggestions on the landscape plan.

Depending on the size, location or significance of a specimen on or abutting a development site, Council may put a monetary bond on a certain planting – which is held until the occupational certificate phase of the development. This is basically done to incentivise a property developer to not accidentally back a bulldozer into some greenery they would prefer wasn’t there.

Even if bonds are not put on individual specimens in a DA approval and a property owner doesn’t risk financial loss through plant removal, they remain bound by the conditions of a local council’s tree preservation order. Lack of adherence to tree preservation orders doesn’t make certifiers or Councils particularly happy and can cause complications at the construction certificate (CC) phase.

Often, a revised landscape plan is required to be submitted at the CC approval stage – one that takes into account building approval matters and any site issues where more resolution is sought by the approval authority. If mature specimens, which were present on site at the DA stage, have been removed by the property owner between DA and CC, specific points in the conditions of consent document will be unable to be met.

Such an occurrence can jeopardise the ‘smooth’ progress of documentation at the CC stage. The certifying authority could insist that mature specimens removed from the site without approval be replaced – which is often a hugely costly undertaking.

So, if you have a long delay between your DA and CC stages, beware using a scorched-earth policy with the grounds of your site. If you do propose garden changes in this intervening period, remember that you had a landscape plan drawn at DA stage. It was hopefully a scheme you were happy with at the time it was prepared, so try to abide by the principles of that design. Aesthetics aside, sticking to the intent of the DA landscape design in any pre CC-stage garden redevelopment will result in fewer complications when that stage comes around.

A garden – pre development application (DA) submission

The same garden – pre construction certificate (CC) submission, the owners having failed to follow the landscape plan as proposed in the DA. The obvious major removal works were done between DA and CC (in this case a five year period). The total remake included the unapproved removal of several stately mature specimens, originally proposed for retention and listed as such in the conditions of consent. The client also failed to recognise that the landscape plan prepared for them at DA stage was an integral part of the planning for their site and not merely a box-ticking exercise.

Plant selection

Plant selection is very important, whether for large urban spaces and parklands or residential gardens and rooftops.

As well as taking into account matters like character, purpose, climatic conditions and habitat, species selection must also consider available growing space.

DSCN1379A Giant Bird of Paradise on a Sydney rooftop

The root system of the Giant Bird of Paradise (Strelitzia nicolai) – seen in the above photo – is aggressive. Planting it in shallow planter boxes or abutting garden paths and underground service conduits is not a good idea.

Generally, small trees planted in a raised garden bed over a slab need at least 1 metre of soil depth. 600mm depth of soil is required as a minimum for shrubs in the same situation.

Even with this principle in mind, it’s best to keep the Giant Bird of Paradise as a planting for substantial open lawns, away from structures. It becomes a much larger specimen than most people realise.
