While both are common approval pathways, they differ in process, flexibility, and suitability depending on the project.

1. What Is DA?

DA stands for Development Application.

It is an approval process assessed by the local council and is generally used for projects that require greater design flexibility or site-specific consideration.

DA approval allows architects to respond more carefully to planning controls, solar access, privacy, streetscape, and overall design outcomes.

2. What Is CDC?

CDC stands for Complying Development Certificate.

It is a faster approval pathway intended for projects that fully comply with NSW planning standards and regulations.

CDC approval is typically assessed by a private certifier and is more suitable for straightforward developments with limited design variation.

3. What’s the Difference?

In general, DA offers greater flexibility in architectural design, while CDC provides a faster and more streamlined approval process.

Projects involving complex sites, custom design responses, or planning constraints are often more suited to DA approval, whereas simpler projects may be eligible for CDC.

4. Which One Is Right for Your Project?

The most suitable approval pathway depends on the site, project type, planning controls, and overall design goals.

Understanding these requirements early in the design process can help avoid unnecessary delays and create a more efficient project outcome.

DA 和 CDC 有什么区别？

在 NSW 进行住宅项目时，很多业主都会遇到一个问题：项目应该走 DA 还是 CDC？

虽然两者都属于常见的审批方式，但在审批流程、设计灵活性以及适用项目类型上，其实存在很大区别。

1. 什么是 DA？

DA（Development Application）是由 council 审核的一种开发申请流程。

通常适用于需要更多设计灵活性，或场地条件较复杂的项目。

相比 CDC，DA 能更充分地回应场地条件、采光、隐私、街景关系以及整体设计需求，因此更适合具有定制化设计需求的住宅项目。

2. 什么是 CDC？

CDC（Complying Development Certificate）是一种相对更快速的审批方式。

它适用于符合 NSW 标准规划规范的项目，并通常由 private certifier 进行审核。

由于 CDC 的审批标准较明确，因此更适合条件较简单、设计变化较少的住宅项目。

3. DA 和 CDC 的区别是什么？

简单来说，DA 提供了更高的设计灵活性，而 CDC 则拥有更快速、更直接的审批流程。

如果项目场地较复杂、存在规划限制，或需要更完整的建筑设计回应，通常会更适合 DA；而较简单、符合标准规范的项目，则有机会通过 CDC 进行审批。

4. 哪一种更适合你的项目？

适合的审批方式，需要结合场地条件、项目类型、规划要求以及整体设计目标综合判断。

在设计初期充分了解审批路径，往往能够帮助项目更顺利地推进，并减少后期不必要的时间成本。

At BJ Architects, we approach every project with care, paying close attention to context, people, and the long-term value of space.

As part of this update, we are pleased to introduce our new website.

A clearer way to present our work

The new website presents our projects with greater clarity and structure.

Projects are now organised across different typologies and scales, including residential, commercial, and interior architecture, making the work easier to navigate and understand.

Each project has also been revisited to communicate not only the final outcome, but also the ideas and process behind it — from concept through to completion.

A more focused experience

The site has been carefully refined to provide a more direct and cohesive experience.

Navigation has been simplified, content has been edited more carefully, and unnecessary complexity has been reduced. Key information is now easier to find, and the reading experience has been improved across both desktop and mobile.

Our aim is to make the work more accessible and easier to understand — for clients, collaborators, and a broader audience.

Introducing AI-assisted interaction

As part of this update, we have also introduced an AI assistant to support user interaction.

It allows people to quickly access information about our projects, services, and approach — whether they are visiting the site for the first time or looking for something specific.

It is a small addition, but one that helps make the website more responsive and easier to use.

Looking forward

The launch of the new website marks an important step in how we present our work.

As the practice continues to evolve, the way we communicate it will continue to evolve as well.

同时，我们也重新调整了每个项目的呈现方式，不仅展示最终成果，也更清楚地传达从概念到落地的设计思考与过程。

更聚焦的浏览体验

网站在结构与内容上都经过重新梳理，使整体体验更加直接、连贯。

导航更简洁，内容更精炼，不必要的信息干扰也被减少。无论是在电脑还是移动端，重要信息都更容易找到，整体阅读体验也更流畅。

我们希望通过这样的更新，让客户、合作伙伴及更广泛的公众，都能更容易理解我们的工作。

引入 AI 辅助交互

在这次更新中，我们也加入了 AI 助手，以提升网站的交互体验。

它可以帮助使用者更快速地获取关于项目、服务及设计方法的信息。无论是第一次访问网站，还是带着具体问题而来，都能获得更直接的回应。

这是一个不大的更新，但也让网站的使用体验更完整、更高效。

新网站的上线，是我们在表达和呈现方式上的一次重要更新。

The post A New Website for BJ Architects | Architecture Practice in Australia appeared first on BJ Architects International.

我们要特别感谢竞赛的发起方——Norman Foster Foundation 和 Arup。Norman Foster先生在全球建筑界的影响力以及Arup公司在可持续设计和结构创新方面的专业贡献，为这项竞赛设定了一个极高的标准，推动了我们思考如何应对重建中的复杂挑战。能够参与到这样一个具有全球视野和社会责任感的项目，我们感到无比荣幸。

这次竞赛不仅是一次设计的挑战，更是一个为哈尔科夫这座受战争影响的城市贡献力量的机会。我们的设计理念着眼于安全、可持续性与社区复兴，期望通过模块化系统为这座城市的重建带来新的希望与活力。我们期望通过与当地社区的密切合作，可以共同打造出一个更具韧性、更加绿色、充满活力的未来。

We are truly honored to have been selected for the shortlist of the Kharkiv Housing Challenge competition and to be the only firm from Australia nominated. This achievement not only validates the efforts of our design team, but also recognizes our commitment to responsibility and innovation in the field of architecture.

We would like to extend our special thanks to the organizers of this competition—the Norman Foster Foundation and Arup. The influence of Sir Norman Foster in the global architectural community, as well as Arup’s expertise in sustainable design and structural innovation, have set an exceptionally high standard for this competition. Their leadership has inspired us to think critically about how to address the complex challenges of rebuilding. It is a profound privilege to be part of a project that carries such a global vision and social responsibility.

This competition has not only been a design challenge but also an opportunity to contribute to the reconstruction of Kharkiv, a city deeply affected by conflict. Our design approach focuses on safety, sustainability, and community revitalization, with the goal of bringing new hope and vitality to the city through modular systems. We are hopeful that by working closely with local communities, we can help create a more resilient, greener, and vibrant future for Kharkiv.

In response to the initiative led by the Kharkiv City Council, the Norman Foster Foundation, and the Arup Group, BJ Architects team has developed a modular system aimed at transforming existing concrete panel housing and improving public spaces. This system includes modular building components, bomb shelters, and the integration of diverse uses at the ground level as integral components of the intervention. Furthermore, the system is designed to provide solutions for the reconstruction of severely damaged buildings, ensuring they embody a refreshed yet distinctly local architectural identity.
