hecticrAt Architects is a Sydney based architectural firm with a keen eye for the creative use of space and nature. We enjoy architecture, and we enjoy the process of working with our clients towards a common goal. The name hecticrAt itself is an anagram of the word Architect.

Each of our designs is a unique solution to the challenges and opportunities presented by the site, your requirements and those of the local authorities. At the same time, each design is grounded in our philosophy that nature and architecture go hand in hand. A patch of dappled sunlight, a cool summer breeze or a still pond… these are as much the building blocks of architecture as a brick is.

Principal architect Demis Roussos Bhargava (NSW registration 8269)
completed his Bachelor of Architecture degree in New Delhi in 2001 and Master of Architecture degree from the University of New South Wales in 2005, both with High Distinctions. He regularly takes part in international architectural competitions, with his entry for the “Kenilworth Designer Dunny” being one of 12 designs shortlisted by the Sunshine Coast Council in 2016 from an international field of 174.

Difficult to not sound unrealistic about this lovely & talented human being. Demis is so easy to communicate with and seems to clearly understand a brief. I was so impressed with him on every professional level and on a personal note, his calm demeanour was so helpful to me through the stresses of dealing with Council and L&E Court. In fact, without Demis’ attention at the correct time, I doubt very much whether I would have persevered through the process to get our DA. One of the things that makes Demis unusual in this industry is that he genuinely wants to give the client exactly what they want, but he’s also very able to suggest other alternatives which he feels might achieve a better result. An architect who listens! An architect who develops and improves on the starting point. An architect who knows the boundaries of tedious legislation and when these can be pushed, and when they can’t. An
architect without arrogance, and a truly lovely man.

Demis helped us re-design our house through multiple consultancy meetings, with a terrific eye for detail, artistic flair and value for money. Demis came recommended for good reason, and we would be happy to recommend Hectricrat to our friends and family

Michael and Kathy, Mosman
We engaged Demis of Hecticrat Architects to undertake a complete renovation and extension of our property, from the design phase right through to tendering and project management of the build. Working with a budget Demis has completely transformed the house and designed a beautiful, functional home that has certainly exceeded our expectations of what we could achieve with the property.

My Husband and I chose Demis from Hecticrat Architecture as we were very comfortable with his experience particularly with the local council and their requirements. Despite our relatively small block Demis was able to design a very modern and spacious home that incorporated every corner of the property along with making most use of the light available. We have also made provisions for the second story. Additionally Demis was able to discuss what would be more cost effective options which we really appreciated as we are not the experts. Based on our experiences I would highly recommend Demis for any of your Architecture needs big or small. I would trust Demis 100% to do the right thing and give you the best possible outcome.

Melissa and Martin, Neutral Bay
Demis is an absolute pleasure to work with. Demis is helping us draw up our dream home, by way of an extension to our existing house and has been incredibly patient, diligent, responsive, organised, proactive and helpful. Demis is very passionate about his work, you can tell he loves what he does and this comes through in his work. Demis is always professional, friendly and easy to talk to. He often sends through suggestions or ideas with no prompting and is always happy to revisit or test how other options might work. He has assisted us a great deal in pulling together our plans for Council and meeting with them. We can’t fault Demis in terms of his commitment, responsiveness and the quality of service he has provided us so far and I look forward to one day completing our project with Demis’ help.

Shiv and Mohini, Roseville
We would like to thank you for designing and preparing architectural plans for our home. We appreciate your patience, professionalism and very soft nature to listen to us. The site being so difficult, two previous architects could not produce satisfactory results. Your level of creativity and ability made it a dream home. Your help to resolve the issues with council and other consultants is also greatly appreciated.

Justin and Anna, Hurlstone Park
Demis, from Hecticrat has been an absolute pleasure to work with. In addition to Demis’ easy going and engaging approach, he quickly got up to speed on our brief, has been very professional, quickly follows through on his commitments, and has been able to create options and solutions in meeting our brief whilst dealing with some challenging site conditions. I’d highly recommend Hecticrat to anyone considering either a completely new build or an addition to an existing home as we have

Mohit and Amita, Rozelle
It has been a pleasure working with Demis on this project. It has taken a couple of years and the end result is exactly what we wanted. We are extremely happy with his professionalism, patience and creativity which has helped us build our dream home. We have already referred him for a few other projects with friends and family
