Just Design
Turn your dreams into reality with a qualified architectural design team that expands your vision and reveals what is truly possible.
From Concept to Completion: The Happy Building Process
Our design-only service keeps everything streamlined, so you do not need to juggle multiple professionals. We take you from the first concepts and drawings through to a complete, coherent design plan. Here is how our design process works:
STEP 1
Initial Meeting
We ignite inspiration from your ideas, understand what you want to achieve, and explore what is possible within your space and goals.
STEP 2
Survey and Creative Design
We carry out a thorough survey to gather essential details, then create two distinct design concepts that showcase the full potential of your project.
STEP 3
Feasibility and Planning
We provide a comprehensive cost guide for both designs so you can choose confidently, then we support the planning process from submission through to approval.
