We meet the needs of the present without compromising those of the future.

Sustainable building design seeks to maximise efficiencies and evolve with the future while maintaining the integrity of the environment. es.au employs various technologies, materials, and concepts. We consider factors such as renewable energy, building orientation, room and window placement, and greenery that all work to reduce energy consumption, emissions, and environmental degradation. Ultimately the client, and those afterwards, stand to benefit from healthier living conditions and savings on maintenance and running costs.

    Makka Constructions
    By Pierre Makhlouf

    Elie and team, thank you for your outstanding service. I have enjoyed the last seven years of service that have been provided to me as a contract builder/developer. You are in my top 5 best value for money businesses. The world would be a much better place if everyone took a leaf out of your book.

    Drafting projects
    By David Said

    ES Design has my full endorsement as an outstanding architecture firm. Our company has been involved in hundreds of construction projects over the past 10 years and we have worked with many highly regarded architects. I have had the pleasure of working with ES Design and the team and will be using them for future projects. In all instances, Elie and his team have been incredibly responsive when it comes to providing detailed drawings and information to support the project. ES Design is very well organised and has an intelligent and experienced team. The ES Design team is incredibly responsive and provided us with timely answers and architectural details as issues come up in the field. Thank you for an incredibly smooth and non-stressful Journey to getting our approval, very much appreciated.

    By Melissa

    Great work by the design team for my new plans.

    Luxury home
    By Anthony Kerim

    I can’t speak highly enough of the service ES Design provided us in the process of doing our renovations. At all times they were helpful, professional and efficient. Also, we used their contacts who were also very helpful. I would like to take this opportunity to thank ES Design & its staff, especially John Nguyen & Elie Sleiman.

    By Duncan Stewart

    Thanks for getting the certification lined up for us. I have to say I’ve been massively impressed with ES Design. Elie has always been a great source of insight and support for me since discovering him. Johnny’s support has also been invaluable. I couldn’t have gotten through this without you all and was literally stuck until I asked for your help. I’ll be back in touch soon to hopefully do the next phase of work and for anything else, I do going forwards. I wish I’d met you guys a decade earlier! Thanks again and all the best.

    Luxury home
    By Joe H

    Once again, Elie, a design where you have outdone yourself! Together with Nicole you designed and managed to get approved a comply and develop within 5 weeks which gave me an opportunity to complete a project within 6 weeks of settlement. All the plans and approvals were done in between exchange and settlement which meant the entire time frame was 11 weeks from the day we bought it at auction until I put it back on the market with a complete makeover. Thanks again! You are an asset to our team.

    By Annie Guo

    Elie, I would like to thank you for your services in designing my house. Completely comfortable with your depth of knowledge and ability, you provided us with a professional service second to none. You are confident and totally committed to ensuring the best possible result is achieved. Your success is built on a friendly, warm approach that is both dedicated and energetic, you are also a firm believer in providing good modern fashioned design, complemented by the very latest in technology. First class service and professionalism from you and your team. Again thank you and I look forward to continuing our relationship with you for many years to come.

    Jocon Building
    By Joseph Ayoub

    Elie, it is with great pleasure that I give this testimony. Throughout the entire period of operating my business(over a decade), you have been involved in many of my projects. Your involvement whether direct for Jocon Building or through a client has been faultless. The care, the accuracy, and the time given by you, Nicole, and your entire office towards each and every project is as always overwhelming.

    Thank you in advance for all future projects.

    Luxury home
    By Scott Coles

    Elie, thanks for all your hard work to make our extensive renovation such a success. You had great ideas for a sympathetic addition to our home and you went out of your way to work with our engineer and the council. I’d be more than happy to be a reference for you for any future clients.

    Luxury home
    By Loui Abouhamad

    Elie has always displayed a huge amount of knowledge on all aspects of design. His attention to detail cannot be overlooked and his easy-to-get-along-with attitude makes any design project simple.

    Luxury home
    By Ves & Ed

    A big thank you to Elie and the team… There was true collaboration throughout the entire design process, which was paramount for us. Watching our ideas sketched out and finally come to life was very exciting. Elie successfully grasped our vision to create the look we wanted. The team made the whole process pain-free with their expertise and professionalism. We would highly recommend ES Design to anyone looking for engineering and drafting services.

    By Nick Katris

    I appreciate your professionalism and promptness on our projects

    By Domenic Belmonte

    Elie, thanks for your assistance with the design and DA submission on our terrace at Leichhardt. You provided the much-needed assertiveness on arguably the most difficult council.

    Luxury home—Bathurst
    By Charles

    Elie, I would like to commend you for your selflessness. It is obvious that you have spent many hours creating such a professional and easy to use resource. You always make life easier for your clients and now, also the public in general. You and your team have always made me feel that I am a valued client despite the many challenges I consistently create for you, you are definitely one that thinks outside the square. Good luck and thanks mate!

    Great job on my home and now starting another project, which ES Design has masterfully worked on.

    Drafting projects
    By Onnix Constructions

    I have worked with many architects / Engineers over the years and Mr Sleiman was extremely accommodating. He is able to provide a complete package from conception to completion. Elie is very competent and understands its not about his own needs but the clients. He came in within budget and has always been available for queries even after completion of the project. I have and will continue to recommend ES Engineering and drafting to all my clients.

    Studio Neon
    By Matt

    Elie, Thanks for a fantastic job with your drafting services for my bar/restaurant DA, studio NEON. Throughout this process you were fast, reliable (and patient with me and my lack of experience) in going through the DA process. You really took the time to understand my project and gave me great advice along the way. I have already recommended you to several people, and would like to use your services again for a residential project next year. Thanks.

    New Home - Lacey Street
    By Simone Elkotby

    Honest to god, thank you so much for the design of our beautiful new home. When you explained to us Ellie in the first meeting about how your own home is so much more difficult to design then a developmental design. I really did not understand until we started getting into the stages of the design. We were blown away with the end result. The result was not in 3D so it was had for me to visualise. Once we started to build our first storey and then the second storey. I could really see your masterpeice come together. Honest to god we are blown away from your attention to detail and how everything has come together to create a show stopper of a house for us. Those voids are brilliant and the separation of the parent retreat and the kids retreat is absolutely brilliant. You are all part of an amazing team and are all brilliant one by one. Thank u so much for creating the best house that I could never dream of. You are all so brilliant one by one. Your service is absolutely amazing Thank u again from Simone and Sharif Elkotby

    Regent St Paddington, Oxford St Paddington
    By Dr Naomi McCullum

    I continue to use ES with every project. They just get the job done without any fuss. I couldn’t ask for more efficient service. They have helped me with a change of use, and a residential development. I am about to get them to help me with another change of use project. Thanks to Elie and the team.
