The SJH Drafting Difference
Process
Our Design Process below outlines the steps we take to create your dream home
Initial Design Brief
Here we meet with you to discuss your upcoming project and take a detailed design brief of what you are hoping to achieve and your budget for the project.
Concept Design
Now we have your design brief we begin creating concept design drawings. These concepts are presented and fully explained to you so that you fully understand the thought process behind the design and we answer any queries you may have. At SJH Drafting we model your project in 3D so you can visualise your design and see how it will look on your site.
Development Approvals
Once the Concept has been finalised and approved, we can handle the Planning Approval process with your Local Authority and provide suitable Architectural documentation to meet Shires requirements to ensure the project obtains planning approval.
Building Permit / Construction
Based on the approved Development Approval we will liaise and coordinate with the required consultants (Structural, Energy, Interior) to prepare full construction working suitable to obtain a Building Licence from your Local Authority.
Tender
We will tender your project out to reputable builders that we frequently deal with on a regular basis. Once we receive the final costings from the Builders, we will present their proposals to you in order for you to appoint a builder and begin construction.
Satisfied Client Stories
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.
Energy Efficiency
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:
- Orientation
- Shading
- Passive Solar Heating
- Passive Cooling
- Sealing of your home
- Insulation
- Thermal mass
- Glazing
- Type of building materials used
- Construction methods

Architectural documentation
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.
