Posted on Narelle EdwardsTrustindex verifies that the original source of the review is Google. 20/09/2022. To whom it may concern. We contacted Kaarlo during a very busy time for the building industry in Queensland. We found him to be very responsive to our requests. He presented us with a range of exciting and attractive ideas for our home renovations. His concepts were well presented and very detailed creating a great scope of ideas. We then narrowed these down for Kaarlo to weave his magic and come back to us with the final plans ready to present to contractors and engineers to get the next steps underway. We are now well underway with the renovations to our family home. Regards Wayne and Narelle EdwardsPosted on Sharon KingTrustindex verifies that the original source of the review is Google. We found Kaarlo to be very efficient and resourceful. He is friendly and easy to work with. He was very willing to listen and please us, while making helpful and innovative suggestions. The work he did was very good value for money. His resourcing and liaising with other companies was very efficient and organised. His communication was attentive and responsive to ongoing needs. We are very happy with Kaarlo’s work and would highly recommend him. Graham and Sharon KingPosted on maggie HerringTrustindex verifies that the original source of the review is Google. I engaged Kaarlo to design our dream holiday home on the Queensland coast. Kaarlo has been approachable and unpretentious throughout the process. He was happy to meet when required and worked with me to achieve an aesthetically pleasing home that met my specific requirements and was sympathetic to the ecologically sensitive environment of the site. His extensive experience and practical advice regarding the many aspects of building design was reassuring. Kaarlo has excellent industry contacts, who are reliable and reasonably priced, and was able to provide additional management services as required. I would not hesitate to engage Kaarlo on a future project and would highly recommend his services.Posted on Stephanie FielderTrustindex verifies that the original source of the review is Google. To Whom it may Concern In 2018, after much reading and searching, I chose Kaarlo Pesu from Environmental Building Designs to draw up house plans for renovating my 30 year-old wooden box house . I had never renovated or built a home before so it was a big learning curve for me, made easier because of Kaarlo’s professional approach and commitment to getting things right for the client. Kaarlo had to create the existing floor plan from scratch as there were no plans on record. He spent a fair amount of time over multiple visits with me walking around the place, hearing my thoughts and ideas, and I found Kaarlo to be a good listener and able to translate my dreams into workable plans. I really wanted the design to incorporate various environmentally sustainable and thermal efficiency principles and ensure the home fitted with its bush location, which Kaarlo was able to do. Kaarlo was calm and supportive throughout the amendments and all my questions. Kaarlo fully explained all the process, so there were no surprises and he arranged all the building approval process with engineers, surveyors, certifiers, town planners etc and arranged quotes to undertake the works – all of which would have been impossible for me without his assistance and advice. Kaarlo’s knowledge and skills in building design options are very comprehensive and his costs were extremely reasonable. He was reliable and responsive, met timeframes and was very good value for money in my view. I now have a beautiful, contemporary new home, designed in keeping with its surrounds and making the most of the views. It is more open to the northern light, with breezeways and better airflow, verandahs creating easy access around the home, there is more practical and open use of the existing internal space, largely improving the comfort, livability and pleasure. And all this was achieved pretty close to my original budget. I would be very happy to use Kaarlo’s services again and very happy to recommend Kaarlo to other folk looking for a good building designer who listens and cares and is affordable. Stephanie FielderPosted on Joel BakerTrustindex verifies that the original source of the review is Google. RE: ENVIRONMENTAL BUILDING DESIGNS. We have used Kaarlo Pesu and Environmental Building Designs for 2 highly successful projects at FlameTree Baptist Church: 1) our present auditorium and 2) our proposed new 1000 seat auditorium with necessary support spaces and services.Kaarlo is an excellent designer, easy to work with, attentive to our vision and creative in response to the inevitable challenges of balancing function, aesthetic design and cost. He is patient with changes and yet meets his deadlines. He is conscientious and invests himself personally in the success of any project. Kaarlo is also professionally able to bridge the gap between design, council requirements and project management, saving time and money wherever possible. We are pleased to recommend Environmental Building Designs and Kaarlo Pesu for the actualization of any development vision. Your sincerely, Joel Baker Senior PastorPosted on Michael GrieseTrustindex verifies that the original source of the review is Google. 5 February 2020 "I met with Kaarlo initially and immediately felt comfortable to engage him to design my Studio and House on my 4 acres in Mapleton. I was living in Victoria for most of the process, so engaged Kaarlo as my Building Designer come Agent to Design & oversee our project from the conception through to Building Approval. I found Kaarlo's communication of the process by both phones and email to be constant and informative. We struck a couple of issues with the council to which Kaarlo stepped up & sorted them out, spending countless hours liaising both on the phone and in-person with the council. The design was exactly as I had hoped it would be, his fees are reasonable and his knowledge of the environmental factors to increase efficiency is fantastic. I would highly recommending Kaarlo for any building project you may have. Michael GriesePosted on John FaullTrustindex verifies that the original source of the review is Google. 21/12/2019 I engaged Kaarlo to help me with a granny flat build project I was working on. Kaarlo’s design work was very efficient, professional and precise. The plans came back looking amazing and was at a very fair price. Not only was the expected work done but also connections to builders and other relevant professionals was facilitated. Kaarlo went above & beyond and exceeded my expectations. I highly recommend this company! John Faull Director YWAM Sunshine Coast.Inc. ABN: 78 4225 86819
