Custom Home Builders

Upon completion of the custom home design and architectural working drawings which form the tender documentation for the building tender process, all custom home builders will be selected by the client through a variety of building partnerships. Threadgold Architecture, on behalf of and approved by the client, invites a number of custom home builders who are interested in costing the custom home design.


All custom home builders receive an identical set of tender documentation and submit a tender price after a nominal four (4) week tender period. The custom home builders shall submit a lump sum price based on the same project parameters, such as; building contract, construction programme, liquidated damages and an identical scope of work as identified in the tender documentation. Following the custom home design tender process, Threadgold Architecture provides a tender analysis to the client for the custom home builders submissions, which can yield significant cost savings for discerning clients. The tender documentation then forms the contract documents along with any addenda issued through the tender period.

Custom Home Builders – Selection

Following the tender closing date and completion of tender analysis, the client has the privilege of choosing the custom home builder based on the lump sum tender price submitted by each tenderer. Lump Sum Building Contracts (not cost-plus contracts) are drawn up and signed with working drawings, specifications and any addenda issued to all the tenderers during the tender period. Should the client desire a full architectural service, Threadgold Architecture can superintend the contract throughout the construction programme, issuing Contract Variations, Extensions of Time and Contract Sum Adjustments should there be valid changes to the scope of building work.

“I’ve known Stuart for about 8 years. At all of our consultant meetings I’ve been impressed by his polite, professional attitude and in-depth knowledge of his profession. His prices have always been fair and very competitive. He has a knowledge that can also save you time and money. He will always make an effort to follow things through quickly and advise you so that you may gain the best outcome for your project. With these things in mind I can thoroughly recommend Stuart.”

“We commissioned Threadgold Architecture for the refurbishment of our house in Dalkeith for both design and contract administration services. We were delighted with the design which Stuart tendered to a select group of local builders. We were also grateful for Stuart’s contractual understanding and attention to detail which kept the builder focussed on the desired outcomes throughout the building process. We are very happy with the renovations and the enjoyment we now get from our transformed living areas.”

“I was very impressed with the ideas that Stuart incorporated into the design for our family home in Perth.   Stuart designed a free-flowing open plan living space that perfectly suits our family of four. Stuart listened to our ideas and delivered the brief within the budget constraints.  My wife and I would be happy to recommend Threadgold Architecture as a business that still promotes the old values of honesty and integrity.”
