Multi-unit development has several council requirements, making it a larger project than duplex or triplex development. Completing a feasibility study of the project will help uncover the strengths and weaknesses of the development, allowing you to make the most of your larger lot. Such developments require larger blocks and a higher density R Code. However, there is a limited scope of design potential and opportunities.

A multi-unit development provides you with a high-density living option on one large block. Such development types have certain complexities and guidelines that may differ from one council to another. At Buildmark Development, we work with you to understand the design possibilities of your property. Our experts will consult with local councils and planning consultants regarding the complexities and realise necessary building guidelines. We also discuss proximity to public transport, parking, storerooms, courtyards, etc. We aim to help you maximise the potential of your lot and make the most of the available space.

Our Multi-Unit Development Process

Getting Enquiry

The multi-unit development process begins with sending an enquiry. Our experts will reach out to you to understand your multi-unit development requirement and design expectations. We believe in involving our clients in pre-construction planning to develop creative ideas and unique designs based on your needs and budget.


Once you approve the design of your development and agree to process it, you have to sign a contract that will include any additional preliminary work. We will fine-tune your multi-unit development design plans and provide you with a fixed final contract price. The contract will cover all the details of the plan, including designs, project time frame, cost, and more.


We now focus on constructing your multi-unit development upon obtaining the necessary official approvals and having a plan in action. Our team of builders in Sydney will always keep you in the loop and provide timely updates.


Once we gather enough information about your development requirements, we reach onsite for a property inspection. Our experts will take necessary measurements, click some photographs of your property, check for easements for services, and consider any existing home features that might impact your development project. Once done, we estimate the budget of your project and discuss the design plan with you.

Permits and Approvals

Before kick-starting your development project, our builders will take the necessary permits and approvals from the officials. We help you avoid unnecessary costs and project delays by liaising with officials about building boundaries, covenants, and zoning. Obtaining permits and approvals is our work, so have peace of mind.

Do I need to purchase land to build a multi-unit?

No. The developers of the project will obtain the land and then sell or lease it to purchasers at a discounted rate. All development plans will be kept confidential, however, we may be able to show you the plan for your property if for some reason you were interested in purchasing one of them.

What should I look for when hiring a multi-unit developer in Sydney?

Firstly, you should check the developer’s track record. Ask them how long they have been developing multi-units, how many they have sold and what their success rate is.

A real estate agent can help you with this. Make sure that you ask the developer for testimonials from their past clients regarding service and value for money.

A multi-unit is a massive investment, but it can earn you big returns if done well.

How do I get an estimated cost to build?

You can get a rough estimate of the cost to build your multi-unit by looking at the current market value of the land. You can then deduct the cost of development and divide it by the number of units or potential apartments that you could build on that land. An average cost to build a 3-bedroom apartment is around $130,000- $175,000 per apartment.
