Warning for CDC Approval Pathways

MWA is providing here a cautionary note relating to recent concerns arising from various projects undertaken via project approval pathways now avaiable via Complying Development Certificates (CDC) by Private Certifiers. NSW State Government has allocated powers of design approval to Private Certifiers, for projects that meet Design Criteria described by the relevant CDC state based legislation. Effetively this allows a Project to bypass the local Council, this being the intended purpose of the Legislation, to take some of the pressure of Local Councils for simple or straightfroward projects that meet a certain set of criteria set out by the legislation.

From a Client’s perspective (an Owner or a Developer), this seems avantageous, as some of Sydney’s Local Councils have occassionally earned a reputation as being difficult or objectionable regarding provision of design approvals. This approval process also gives the appearance of having more certainty, as the relationship with the Private Certifier can be more easily articulated and understood than the often rather disparate and cantankerous response from local councils regarding significant project matters and concerns, as well as appearing to offer the benefit of a much shotened time frame to gain the consent, compared with an almost unknown or undefined timeline for gaining the consent through a Local Authority. Of course in some instances, after a lengthy and costly development aplication process, a Local Council may decide to simply not decide, obviating all preceeding effort and discussion around the project.

However, obtaining a design consent via a CDC does not come with some significant concerns that need to be carefully considered on a project by project basis. Sometimes, CDC provides a benefit for certain projects at certain stages,whereas sometimes a DA is more appropriate for other projects:

_ Loss of Yield: CDC rules are usually much more restrictive in terms of development potential and there is no room for interpretation of the rules – which must be complied with expressly

_ Extra Over Documentation Risk: When a Client approves a drawing for DA submission, and those Drawings are approved by the local Council, those drawings then become the design control for whatever is built later ie. these drawings supercede and replace whatever local council planning rules are relied jpon in forming the design and gaining the approval. This means that if, as might often occur, there is any different interpretation of the application of a DCP or LEP rule, it is not of concern as the COuncil stamp on the Drawing means that that is now the legally buildable form, with no other question aboe to be asked. However, CDC rules never go away, a building built to CDC must always comply with every single CDC rule at all stages of its design, construction, occupation and use. This becomes a serious risk when we consider the next point.

_ For buildings built in locations where litigious neighbours are nearby (which means virtually the whole of the North Shore), any other person can, within 3 months of the CDC being issued, bring to the attention of the Local Court, any alternative opinion on interpretation of a CDC rule or criteria, which then, the Court will rule on. COurt battles are stressful, volatile and expensive, often issuing confusing rulings. This means, a project could find itself caught up in a court battle almost as soon as the construction certifiate is issued. There is no way around this, CDC drawings must be provided to surrounding neighbours before construction commences. These neighbours can form their own opinions on the relative compliance of the Project with CDC rules or worse, may just be delivberately objectionable for strategic reasons.

_ Any mistakes or non compliances identified in the original CDC, invalidates the whole of the CDC. Any Building works completed under Authority of this now invalidated Certificate, also become invalidated and must be deconstructed.

_ As noted above, a three month window exists for Neighbours to lodge Objections to the CDC at the Local Courts. This window applies to any amendments to the CDC, which must also be notified to the adjoining neighbours. So the time gains that seemed apparent at the outset, versus a DA approval, now greatly elongate such that they are relatively the same as a DA. This loss of time advantage means that the only thing gained is additional construction risk arising from the compliance requirements for a CDC versus a DA.

_ Private Certifiers have limited indemnities and it can be seen from above, that the value of the problems that arise could be very large. If a Private Certifier liquidates when faced with such a problem, or their insurer does not agree to pay their claim, the Client is potentially left without compensation for what could be a very egregious error.

Applications to Council are, from a Client or a Developer’s point of view, difficult or unpredictable. But it is a mediated process that, in the long run, provides a good solutio for the whole of the community regarding a particulr development. As well as that, the approval, once finally gained, offers ultimate surety s to its constructabilty. As such, MWA are providing a warning to Clients to be exceptionall careful when considering CDC’s versus DA approvals, particularly for complex project and sites with litigious or strategicallly oppposed neighbours.

Sydney Rooftop Expansions

Within the Sydney Harbour Urban Frame, houses and apartment buildings fortunate enough to be positioned to have the benefit of city views, will always find that those views are best enjoyed from the roof. A broad number of buildings in this area were constructed before 1970’s and many have flat roofs. Because of way concrete was mixed and poured in those times, structural engineers often significantly overspecificied the strength of the concrete structures. As a consequence, many existing buildings have extra over load capacity that is not used by the exissting structure and can be assessed to confirm that additional load can be added to the building, without any addition to or improvement of the existing structural frame. This means that, strutures can be added to roofs, without requiring any work on floor below.

The key advantage of this arrangement is that, because a worksite can be established on top of the building, with works being completed entirely within the building parapet, and smaller gantry cranes can be used to provide for loading and unloading of construction materials and waste from the kerbside to the roof, building works can be completed with virutually no interruption to resiidents living on floors below.

Advances in modern roof tanking and membrane systems means that such works can be completed without putting the floors below at any risk of water ingress either during construction or in the permanent condition. The new floor or floors constructed on top of the existing building, sit above the existing roof slab, by about 600 – 900 mm clear to underside of structure, allowing for all services to be rticulated in this new cavity to conjoin existing building service riser locations again, without causing any interruption or increasing any risk to residents living below.

This means that a body corporate or strata can sell it’s air space above the building, by volumetrically subdivision. income from the sale of this airspace can be used for any purpose as determined by the building strata or management – building upgrades or refurbishments, additional facilities or improvements, or simply money in the bank.

Many of Sydney’s rooftops are underdeveloped s well as their rooftops, having incredible views, and new floors could be constructed in certain loations without impacting or restriting views from neighbouring properties. Because some of these older properties are significantly under-developed, some of these projects, may be constructed ‘as of right’, via new CDC legislation delegating powers of design approval to private certifiers.

The example here, is a rooftop addition to a large executive house on one of Waverton;s best streets, taking full advantage of the incredible 270 dgree views available from the rooftop. This kind of thinking can be expanded to include for prefabricated ‘pods’ comprising anything from a single bedroom or studio, right through to a two storey, loft style penthouse.

Boat House

Boat House | Lavender Bay, Sydney

Inspired by the locations incredible views out over Lavender Bay and Sydney Harbour, we sought to capture the essence of Sydney’s nautical heritage in a unique and expressive new design that transforms an existing 2 storey residence with generous proportion, to a unique and special 6 bedroom, 6 bathroom house, with a gallery space and basement area for 6 cars.

The House design carefully considers Feng Shui, and the way in which internal spaces relate to outside, to create a beautiful and memorable garden, as well as incorporating a ‘bath house’ and a very generous pool at 15 metres in length.

Design features of the existing house are incorporated to the new design in a way that both makes the most of the value of the existing house, as well as creating interesting and unique design features for the new design.

Sydney’s Heritage Fleet

MWA are working in support of bringing the remarkeable Sydney heritage Fleet to a permanent, publicly accessible home in Berry’s Bay. Over 30 historic boats, and a range of maritime restoration projects brings the unique, interesting and culturally significant maritme history of sydney to a permanent home in Sydney’s Berry’s Bay.

The Fleet’s vessels range in age from 1874 to the 1960s – among them five more than 100 years old. What makes them exceptional is that each and every one is fully restored and in operation.

Since 1965, Sydney Heritage Fleet, a not-for-profit, volunteer-led organization, has worked to preserve and present examples of the ships, artefacts, literature and art which tell the story of Sydney’s maritime history.

Cairns Yacht Club

After relocating from within the Cairns Cityport land development bundle, Cairns Yacht Club (CYC) found themselves without a home. Matthew has worked with the club to visualise expansion opportunities, so as to articulate a project brief, identify project stakeholders and mobilise on opportnities. This project is the final piece of the puzze for the Cairns City Waterfront for Matthew, bringing together his work in designing the Cairns Esplanade and Cairns CityPort Masterplans.

Lavendra Restaurant Expansion

VIsiting the site of this unique restaurant, we saw immediately that it reflects the beauty and wonder of indian Culture as well as embracing and being a part of Sydney’s Lavender Bay Gardens Precinct. We are so excitied to find this unique coalescence of cultural factors as we know it will drive our creativity.

We have been asked to provide a concept that provides the Owner and Culinary Visionary, the opportunity to expand his culinary expression, taking advantage of a unique and beautiful local site to become one of Sydney’s, and indeed the World’s, premier Dining Destinations.

With expansive and unlimited views across Lavender Bay to Luna Park, Sydney Harbour Bridge, the Sydney Opera House and Sydney City, and nestled in a beautiful and bountiful patch of local Rainforest, the new designs will inspire a culinary experience like no other.

The project utilises pre-fabricated construction to reduce downtime for the operating restaurant business as well as facilitate construction on a relatively small site where builder access is somewhat compromised. This turn-key solution for a prefab project, will significantly reduce time on site, provide more certainty as to the construction time period, and through intelligent design, provide for a unique, interesting and completely bespoke architecturally designed restaurant expansion.

Chatswood Office Tower

Matthew was invited by Knight Frank Property to provide Design Concepts for a new Office Tower on a complex site within the high-density frame of Sydney’s inner-city suburb of Chatswood.

Based on the idea of a Moth about to take flight, and the unique and interesting patterns on its wings, the Façade Design and Tower form provided a unique and interesting refresh of a commercial office building. Touching the ground lightly, instead of landing on a built podium, the tower’s lower floors open up to provide interesting and unique external garden spaces and a range of staggered terraces supporting outdoor dining and retail experiences in a uniquely lush and landscaped local environment. In combination with hydration and irrigation of these garden spaces, this ground floor ‘zone’ will provide a comfortable self-regulating outdoor microclimate, year round.

Completed in under two weeks, the Project also demonstrates Matthew’s ability to work quickly with the REVIT model and hand sketching to produce reliable project yield characteristics and planning compliance diagrams, and at the same time create unique, interesting and resolved design

ANU Campus Revitalisation

Working with Peter Tonkin from TZG Architects, Matthew provided design ideas for a new Building to be located on ANU’s central spine, and complement several major new projects recently completed there.

The design concept sought to take advantage of Canberra’s pleasant outdoor environment and provide a sense of openness, transparency and accessibility for ANU’s students. The Concept also explored Matthews interest in large span structures providing shad and weather protection, with enclosed spaces as ‘pods’ providing mixed mode, temperature controlled internal environments.

Townsville City Hotel Feasibility

Matthew was invited to assess the development potential of a large inner city site in Townsville, if consolidated with an adjacent government-owned land parcel about to come to market. The project includes a basic and workable design, suited to the budget accommodation model of the Client, as well as a development matrix that indicates project yields and built areas.
