Defining Your Vision and Requirements Upfront

Taking time to thoroughly plan project objectives and constraints enables your architect to produce the most fitting concept options aligned with your expectations.
Gather Inspiration and Reference Materials
Collect images, floor plans, sketches that exemplify your desired look and layout for the space. Provide granularity on must-haves versus nice-to-have elements. Define any immovable existing structural elements.
“We always ask clients to share photos of other interiors they love, so we understand aesthetics that appeal to their lifestyle,” explains Graham.
Set Expectations on Scope and Budget
Be realistic about how much you can invest into the project and what you want achieved. Outline tradeoffs you’re willing to make, like finishes vs space. A tighter budget may drive phasing considerations. Know that even a detailed brief only provides guardrails for the architect’s creativity.
Draft an Initial Architectural Brief
Consolidating this key information ensures alignment and provides the architect critical guidance on transforming your ambition into tangible design solutions.
“A clear brief is crucial – it enables us to tailor options specifically to what clients need functionally while meeting planning requirements,” emphasizes Bob. “We can then maximize opportunities around orientation, flow, light, etc.”
Helpful References to Supply Your Architect
- Site surveys with exact boundary and level markings
- Local conservation area appraisals if applicable
- Photos of current space to demonstrate architectural needs
- Any existing floor plans for extensions or renovations
- Inputs from structural engineer or party wall surveyor
Thoroughly preparing these materials gives your architect the best possible starting point for concepting.

“Aim for an architect who proactively surmounts obstacles with creative solutions rather than presents limitations or risks alone. They steer the journey,” Graham suggests.
Developing Design Concepts and Managing Iterations

Your architect synthesizes all gathered requirements, inspiration sources, and feasible opportunities to put forward considered concept options balancing functionality, aesthetics, and practical construction implications.
Provide Rapid Initial Feedback
Voice pros and cons on each option’s layout, features, and visual appeal based on your lifestyle needs and tastes. This input gets incorporated into refined versions for further consideration, using your architectural brief as guideposts.
“We present around three distinct initial directions, then collaborate closely with clients to adjust elements like walls, openings, finishes to arrive at a personalized scheme,” shares Bob.
Address Challenges Openly
If preliminary preferred designs exceed stated budget expectations or clearly conflict with planning policies, acknowledge and resolve through open dialogue. Compromise on certain specifications or scope if needed. Your architect’s responsibility is ensuring your ambitions manifest realistically.
“Remain actively engaged with how choices impact cost and schedule – significant variations late can increase fees and timeline,” advises Graham.
Approve Final Drawings
Provide sign off on the ultimate floor plans, sections, and elevations which get submitted to council for approvals. Your architect should also create quality 3D visuals and an area schedule breakdown for contractor pricing.
Overseeing Construction Delivery and Completion Phases

With consents secured and a builder contract in place, regular collaboration continues between you and your architect throughout the hands-on realization:
Key Architect Involvements Across Build Stage:
- Early quality inspections of groundworks and foundation pouring
- Periodic validation of key build milestones against drawings
- Raising flags early on any Helsingør passing and material delivery
- Management of change requests and budget tracking
- Support with contractor negotiations if complex dispute resolution becomes necessary
- Schedule coordination and input during finishing selection finalizations

Your participation stays crucial as well to promptly decide on changes, identify deficiencies, and sign completion certificates.
“Constant communication across the triangle of client, architect and builder mitigates surprises and ensures transparency into progress,” Graham emphasizes.
