Our Consultation Process in Action: A Case Study

Dive into a real-world example of how our Build Cost Estimate & Return Brief and Feasibility & Sketch Design was undertaken for a home renovation and extension project in Kew.

THE RESULT: Our client gained a clear roadmap of their project and could move forward with confidence and clarity. Learn more below.

Working closely with the client and a talented architect, RoomFour was instrumental from the inception, ensuring that design, site conditions, and budget harmoniously intertwined.

Starting off, our client filled out a detailed questionnaire, setting the stage for a collaborative discussion. This led to an on-site visit to get a real feel for the potential of the space. With everything aligning, a Preliminary Agreement was put into place, committing to delivering a comprehensive Return Brief and Feasibility Study.

Our first task was navigating local council guidelines and assessing the property. On our site visit, we deep-dived into the client’s space needs, their budget, and lifestyle aims. These insights became our guiding light, ensuring the project stayed true to its vision, especially during decision-making moments, later on in the design process.

The outcome? Three thought-out layout sketches, each with a clear cost-estimate breakdown. We then sat down with the client and the architect, discussing the feasibility results and our proposed concepts.

Frequently Asked Questions

The cost of constructing an architectural home can significantly vary, often quoted per square meter. This variation primarily stems from the build’s complexity, influenced by both the site’s characteristics and the design’s intricacy. While finishes also affect the overall cost, their impact is generally less pronounced compared to the other factors. On average, the starting price for architectural homes is about $4,000 per square meter. However, for projects involving a) challenging sites, b) intricate designs, and c) premium finishes, costs can escalate to as much as $10,000 per square meter or more.

The cost comparison between renovating/extending and building a new home depends on various factors, including the scope of the renovation, the existing structure’s condition, and the level of customisation desired. Renovations and extensions can sometimes be more costly on a per square meter basis due to the complexities of integrating new designs with the existing structure, unforeseen challenges, and the meticulous work required to match the old with the new. However, building a new custom-built or architectural home involves the cost of new construction from the ground up, which can also be significant, especially for high-end, architecturally designed homes. In general, the decision should be based on the specific needs, the value added to the property, and the desired outcome rather than cost alone.

The cost of building a Passive House can vary widely, influenced by factors such as location, design complexity, and the materials and technologies used to meet the stringent Passive House standards. These standards require high levels of insulation, airtightness, and energy- efficient systems to significantly reduce the building’s ecological footprint. On average, building a Passive House may command a premium of about 10% to 20% over the cost of standard construction, depending on the specific requirements and finishes chosen. However, for higher-spec architectural homes, this difference can be as low as 3-5% because a significant portion of the budget is allocated to high-end finishes, making the premium for achieving Passive House standards less significant. 

This initial investment is often offset by the substantial savings in energy costs over the life of the home, making it a cost-effective choice in the long term. In general, high-performance or Passive House homes can start between $4000-$4500 per square meter, however this price can quite easily increase, where just like building any other home, with added complexities and more high-end, refined finishes.

Architects’ fees can vary widely based on the project’s complexity, the services provided, and the architect’s experience and reputation. Generally, architects charge in one of three ways: a fixed fee for the entire project, a percentage of the total construction costs (typically ranging from 8% to 15%), or an hourly rate for more consultative services. For residential projects, including custom homes and renovations, the percentage of construction costs is a common method. The exact percentage can depend on the project’s scale and complexity, with more intricate designs and higher-end projects possibly attracting higher fees. It’s important to discuss and agree upon the fee structure upfront to ensure clarity and alignment on expectations. 

At RoomFour, we predominantly offer a fixed-price service for our architectural projects, providing our clients with clear, upfront costs. On the odd occasion we may opt for a consultative basis or a percentage-based fee structure, depending on the services needed.
