Architect vs Draftsperson vs Building Designer – what’s the difference?

Houses designed by architects sell for higher prices than the ones designed by the building designer. I would explain why ;

  • Registered Architects have the Highest academic qualifications, and often they have Bachelor's and Master's degrees. While other Building designers need no or minimal academic qualifications other than drafting qualifications or skills.
  • Architects must undertake many Tests and Exams to ensure they are qualified to design high-standard buildings that contribute to urban design and don't affect the environment negatively. While Building designers, they do not do that.
  • Architects are permitted to build more than three-story buildings, while Building designers cannot build higher than a three-story building.
  • Architects must renew their registration annually and submit evidence of their Continuing professional development  CPD. The CPD means that architects continue to update and develop their knowledge and skills. While Building designers are not required that.
  • Architects design your house and your lifestyle living at it and design each building from scratch. While building designers usually design spaces, shapes and copy-paste used designs with few modifications, circulating similar designs around.

 Apart from the above, sometimes experienced building designers that develop themself, break these records. And usually, work on gaining their registration as architects. so they turn out to be architects. usually, architects started as building designers, gain years of practical experince and work their way up until they can be qualified architects.

As a result, architects are more qualified and knowledgeable, so their products would reflect that. And accordingly, their building would look amusingly great and sell for a higher price.

The owner-builder: everything you need to know about council approval

Yes, you need council approval to build.

Development consent is required in most instances. There are generally three pathways for development: 

  • Exempt development covers certain types of minor work where no application for planning or construction approval is required; however, it must meet some standards. For example, to build a terrace, fence, internal decoration, painting, or garden shed, you don't need council approval, but you need to consider some rules that regulate these items. Council can make a random check on properties based on neighbor complaints to check if you start construction work that does not comply with codes and regulations or are not exempt and need a development application. 

  • Complying development [ CDC] application; covers work that meets specific pre-determined development standards and can be assessed and approved by a certifying authority (council or private accredited certifier) in 10 days or 

  • Merit-based assessment [which requires a DA then CC], must be submitted to a consent authority (usually council) for assessment. This path will give more advantages to your development and flexibility, but only if you use an experienced architect to design within all codes and regulations. You can get a more extensive and elegant house using this path compared to the previous path of complying development, as complying development is rigid and strict. The government needs to use a private certifier for a smaller project, but they control the result by stricken rules. This way council frees up the merit-based system for more complex and sensitive developments. 


Some clients think that CDC is a better choice than DA when building their dream home, but the fact is not. The only advantage of CDC over DA is that they get approval quicker.

What is a Construction Certificate & when do I need one?

A Construction Certificate [CC]  is a formal request submitted to the authorities [ Council or Private Certifier]. you need it when you want to start building and you already have DA approval for the development. CC comes after DA or sometimes you combined them both in one application. CC approval is required before you start Building and after you get DA approval.

The CC usually contain ;


- all DA approved and stamped plans & documents ;

- Structural engineer details 

- Architectural Plans detailed for construction purposes.

- some other reports and details according to the project type.

 

Once CC approval is granted, you can start building according to approved plans. The building inspector from the council or the private certifier will inspect the building process accordingly. Once you finish, you need an occupation certificate to occupy the building. 




What is a Development Application [DA] & when do I need one?

 

Development Application [DA] is a formal request submitted to the relevant council. It is required when you want to get council approval of a specific Design of a development. it required for building new buildings such as new dwellings, duplex, townhouses, apartments, or more complex buildings. but it is not required for minor renovation or construction work, such as installing air-conditioning units, building balconies, decks, patios, pergolas, terraces, and verandahs, cabanas, cubby houses, ferneries, garden sheds, gazebos and greenhouses, carports, driveways, fences, and minor alterations. you don't need council approval for these exempt development, but you need to consider some rules that regulate these items


A Development Application [DA] usually include  ;


- all architectural design details and specifications

- Statement of environmental effects 

- BASIX certificate

- Hydraulic engineer plans.


Sometimes the land is in hazardous areas, such as flood or bushfire areas. In this case, you need different design solutions and detailed reports to indicate how the design deals with the hazard and supports your design. 

Once DA approval is granted, you need CC approval from the council to start building.

Council Approvals For Renovations – DA, CC and CDC

How to get council approval?

The short answer is by Hiring a qualified architect. 


Choosing the Architect is the most crucial second step after choosing the location of the lot. A qualified and experienced architect will design your lifestyle and your daily routine. The Architect will design it from the first moment you wake up at that house until you go to bed. It is way more than creating space. Let me tell example;


Suppose your  Master bedroom has a large sliding door that opens to a balcony. The Balcony overlooks a nice view. Suppose the glazed slid door ordinated toward the east north makes early sunshine rays come into your bedroom. Imagine sleeping in your comfy bed, rays of early sunshine coming to your bed. You wake happy as sunlight has magical effects on us. Then naturally, you will come by the window to look at a wonderfully landscaped backyard or a unique view. It will inspire you to breathe for minutes; now you did YOAG, that is good for your being... The Architect encouraged you to do it naturally.


That was a simple example of how an Architect can design your lifestyle and daily routine. 


   Example of what a house designed by an Architect would look like. A Beautiful piece of since and art designed By Luigi Rosselli, Located at   Hunters Hill, NSW Link: https://luigirosselli.com/residential/sticks-stones-home 


But before you start building your dream home, you need to know that you need council permission. And to get it, you need to request that formally by submitting a development application. The development application will contain many documents that demonstrate the design and compliance with all relevant Local environmental plans [LEP] and Council development controls plans [DCP]. 


The good news is; that you, as the owner, don't need to know much about the approval process. It would be best if you had someone whose job is doing that, I mean an architect.


Architects lead their team and prepare all related documents ready for submission, and they will follow up with the Council until approval. And architects can extend their service by working the building process after the approval until you get the occupational certificate and settle in your dream home. 


Owner Duty  is to corroborate; 

    It is essential to express your needs to your architects. The design needs to reflect and suit your personality, needs, style, and budget. It would be best if you remembered that; the resulting product would last for decades. And any mistake will be difficult and expensive to be erected plus fixed. Besides complying with rules and regulations, owners should corroborate with the Architect to get a design that suits them.



    The Architect Will,


    • Design the house;

      The Architect will start by analyzing the Lot specifications. Such as location, area, shape, size, frontage length, overall land slop, surrounding buildings, etc. 

      They will organize with a qualified Building surveyor to prepare a detailed survey plan. Then They will start the design phase—the need to design according to all relevant Council's rules and regulations. The Architect will keep developing the design until it complies and make sure the client approves plans. 

      The Architect must inform the client of all design details by sending him a copy of the architectural plans and details to check and confirm if he is happy. Ideally, a meeting needs to be held and discuss the design and get client confirmations or notes. It is a long process, but it is a fun process too. Enjoy it.  


    • Manage consultants;

      After that client prepared the final set of architectural plans and details. Now They need to manage consultants, Such as; Building surveyors, Landscape designers,  hydraulic and structural engineers etc.


    • Prepare the Plans and documents to support your Development application.

      The central part of the application is the design itself, so the architect main duty is to provide you with a final and detailed set of drawings. The set will include all architectural Plans, elevations, sections, Site analysis, Stormwater concept plan, landscape plan, waste management plan and schedules of material and finishes, .etc. Note, the Architect will organize with some consultants in the early design stage. Such as hydraulic and structural engineers. 


      Then the second part is Few Documents that support The Design and demonstrate how the plans comply with codes and regulations. It could include a few reports and details, such as; BASIX Certificate, Statement of Environmental effects, Traffic report, Flood control report, Arborist Reports and fire safety report ...etc.


      The third part is filling the application form and get the checklist as the Council requires. 


    • Submitted to the Council and follow up with you and the Council until approval.

       The Architect knows which type of application you need to submit. Wither the [DA], [CC], combined [DA & CC] or [CDC]..etc.

      After submitting your development application, wait for the council decision. Council will check the design. If they ok with it, they will stamp your documents and send them back to you with the approval letter.

      Otherwise, Council might contact you requiring further supporting documents or modifications. 


      Owners don't need to worry as architects have the experience to deal with councils and authorities. They will guide you professionally and get the best outcomes. 

      In a worse situation, Council might refuse your application for many reasons. One of them is that the design does not comply with code and regulations. And they will send you a letter of the specific reasons. 


      Architects need to advise their clients if they believe that Council does not permit their projects. Suppose The client still wants to go ahead. In that case, he is responsible for any outcome. He pays the architect fee fully whether the application is approved or not. Architects helping clients to get approved, but it is the council decision at the end of the day.

    5.3.1    BASIX

    On the 1st July 2004, the State government introduced BASIX, which consolidates planning provisions relating to water consumption and greenhouse gas emissions. A BASIX Certificate is provided with the application demonstrating the applicant’s commitments in achieving the objectives of the state government’s policy. The BASIX SEPP states in clause 8 and 9 that:

     

    “‘competing provisions’ in an environmental planning instrument or Development Control Plan are of no effect about a residential development proposal required to be assessed by BASIX, ‘to the extent to which they aim:

    (a) To reduce consumption of mains-supplied potable water, or reduce emissions of greenhouse

    Gasses in the use of a building to which this Policy applies or in the use of the land on which

    Such a building is situated; or

    (b) To improve the thermal performance of the building to which this Policy applies.’”

    It is proposed to install a rainwater tank as specified at the BASIX certificate to hold water for the proposed principal dwelling, to be used for flushing toilets, clothes washing and outdoor irrigation, which satisfies the requirements of the policy.

    Energy conservation principles will be achieved through the construction method and orientation of the building, together with future thoughtful planting of trees and shrubs.

     

    5.3.2    Internal Driveways

    A relatively level site ensures that appropriate driveway grades can be achieved following AS 2890.2 - 2002. The Architectural Plans provide a driveway profile to demonstrate compliance.

     

    5.3.3    Waste Disposal & Re-use Facilities

    A Waste Management Plan will be submitted as a separate document to accompany the demolition application. The plan adopts the principles of Avoid Reuse Recycle and Dispose to minimise landfill waste.

    5.3.4    Crime Prevention through Environmental Design

    Design guidelines outlined in the Crime Prevention through Environmental Design (CPTED) were considered and incorporated as follows:

    ·         Provision of a clearly visible entry point facing the street;

    ·         Passive surveillance treatment has been provided through the provision of habitable rooms and a balcony which face the street;

    ·         Suitable landscaping will produce a defensible open space at the front, resulting in some interaction with the public domain beyond; and

    ·         Boundary fencing and gates will be provided to prevent intruders from accessing the private open space area.
