The SJH Drafting Difference
Satisfied Client Stories
We have been using SJH Drafting for our fencing projects around Perth for several years. Shaun's knowledge within the building industry and being across council regulations and requirements here in Perth has been invaluable in our dealings. This combined with the high standard of detail in his drafting makes for a service which is second to none. He has completed detailed drawings for us from boundary retaining walls to full front boundary brickwork with gate access, ensuring not only that it complies with residential design codes but that it is also functional and aesthetically pleasing. Shaun is friendly, prompt, reliable and honest and his prices are extremely competitive. As well as working with us on projects for our company, he has now completed several jobs for our home renovations too (detailed house plans and a carport addition). We highly recommend SJH Drafting, whom we will continue to use in the future.
We found that Shaun was easy to deal with, really personable and gave us great design ideas when we were looking to add a two story extension on to our existing home. He delivered final plans in a timely manner, consulted with both us , structural engineers and the council, making what has in the past been a tedious process fairly straightforward. I wouldn't hesitate to recommend Shaun to our family and friends when they need drafting services in the future.
We have worked with Shaun from SJH Drafting for over 3 years. Shaun has a great knowledge of all aspects of construction, which shows in the quality of his drawings. As a builder, this enables us to deliver projects on budget and on time.
I wanted to take a few minutes to let you know how pleased we were with your service. The entire process was seamless and handled in a timely manner. Your expertise in how best to realise our vision, whilst keeping our strict budget requirements in mind, made us feel comfortable in our decision. Thank you again for your assistance and we cant wait to utilise our new space.
My wife and I could not have been happier with the service and results that we received from Shaun for the renovation design of our 1940's character home. Shaun not only drew up and modelled exactly what we were after, but also made significant design improvements that we would not have considered, were it not for his innovation and advice. Shaun also displayed a comprehensive knowledge of our local councils planning requirements and facilitated the entire approvals process, saving us a lot of angst. Shaun maintained a high level of communication throughout the entire process, and provided regular status updates along the way. We would like to thank you for the exceptional level of service that you provided and would wholeheartedly recommend you to others seeking high quality drafting and design services.
Residential Energy Efficiency Assessments
SJH Drafting provides energy assessments for all new residential dwellings, duplexes and apartments using The NatHERS (Nationwide House Energy Rating Scheme). NatHERS is the most common way to show that a new home meets the minimum state and territory building energy efficiency requirements based on the National Construction Code (NCC).
It involves modelling your design using accredited software (FirstRate™). This advanced software analyses your building and assessors the heating and cooling loads required to keep your house at a comfortable temperature and provides you a star rating from 0-10 stars based on your design. In WA you are required to achieve a minimum energy star rating of 6 stars to achieve compliance.
By incorporating some simple Passive Design Principles into your home design, you can reduce your heating and cooling costs, improve the overall energy efficiency of your home and make it more comfortable space to live in and above all reduce the greenhouse gas emissions for the life span of you home.
Passive Design Principles relate to:
- Passive Solar Heating
- Passive Cooling
- Sealing of your home
- Thermal mass
- Type of building materials used
- Construction methods
Residential Energy Services
- Single Storey Homes
- Two Storey Homes
- Custom Designed Homes
- Unit Developments
SJH Drafting is ready when you are
Architectural Documentation is one of the key facets of the design process. The process of methodically developing construction types and materials and making them dimensionally correct to form a building detail that interacts with its surrounding elements provides the builder with a detailed record of how all aspects of the building will fit together to make up the building form. This helps the builder to estimate, plan and construct from and makes for a seamless building process.
