Commercial Projects - Common Mistakes & Roadblocks, and How to Avoid Them

Commercial interior design projects can be complex and challenging, and there are several common roadblocks and mistakes that businesses may encounter during the process. To avoid these obstacles, it's crucial to work with an experienced and trusted partner who can guide you through the process and help you make informed decisions.

As a diploma-qualified interior designer and Design Institute of Australia member specialising in commercial projects (including Moves International office and Saravanaa Bhavan restaurants), I've witnessed these mistakes repeatedly. This guide helps you avoid them.

Common Mistake #1: Under-Estimating the Scope

One of the most common mistakes businesses make is under-estimating the scope of the project. Interior design projects involve several stages, including design, implementation and installation. Delays in any stage will have an impact on the following stage, so it's essential to have a clear understanding of what each stage entails and considering the impact of late changes.

Why this happens:

• Focusing only on the "fun" design part

• Not understanding technical documentation requirements

• Underestimating council approval timelines

• Ignoring trade coordination complexity

• Failing to account for business continuity during work

Real consequences:

• Timeline blowouts of 30-100%

• Budget overruns from unexpected costs

• Business disruption exceeding planned downtime

• Rushed decisions leading to poor outcomes

How qualified designers prevent this:

At 360 Design Studio, we break projects into clear stages with realistic timelines:

1. Design Stage (2-4 weeks):

• Site survey and measurements

• Concept development

• Technical drawings

• Material specifications

• Building code compliance verification

2. Approval Stage (2-8 weeks depending on complexity):

• Council approvals if required

• Strata approval if applicable

• Stakeholder sign-offs

3. Implementation Stage (4-12 weeks depending on scope):

• Trade coordination via Trade & Materials Schedule (TMS)

• Material procurement and delivery scheduling

• Site management and quality control

• Issue resolution

My Diploma in Interior Design (Interior Design Institute, 2024) taught me realistic project scoping, preventing the under-estimation that plagues businesses attempting DIY commercial fit-outs.

Common Mistake #2: Not Having a Well-Defined Budget

Another mistake businesses make is not having a well-defined budget for the project. It's crucial to have a realistic budget in mind before you start the project to avoid overspending or making compromises on quality.

Budget components businesses often forget:

Design fees (typically 10-15% of project cost)

• Qualified designer fees

• Technical drawings and documentation

• 3D visualisations

• Specifications

Building compliance (5-10%)

• Council application fees

• Building certification

• Fire safety compliance

• Disabled access requirements

Project management (8-12%)

• Trade coordination

• Site supervision

• Quality control

Contingency (15-20% for commercial)

• Higher than residential due to complexity

• Code compliance discoveries

• Technology integration issues

• Heritage building constraints

Ongoing costs

• Higher energy bills from poor lighting design

• Maintenance costs from incorrect material specifications

• Early replacement from cheap materials

• Lost productivity from poor layout

How we help with budget clarity:

At 360 Design Studio, we charge fixed fees based on project complexity, not percentage of construction cost. This eliminates conflict of interest and provides budget certainty.

We provide comprehensive cost breakdowns upfront showing design fees, estimated construction costs, required approvals, contingency allocation, and ongoing operational costs.

Common Mistake #3: Not Involving Employees

Businesses may make mistakes during the planning and design stage by not involving employees in the design process or failing to consider their needs and preferences. This can result in an office that doesn't meet their expectations or doesn't work efficiently.

Why employee input matters:

Workflow understanding:

• How teams actually collaborate

• Technology and equipment needs

• Storage requirements

• Privacy vs collaboration balance

Wellbeing factors:

• Natural light preferences

• Temperature control needs

• Noise sensitivity

• Ergonomic requirements

Productivity drivers:

• Meeting space requirements

• Quiet focus areas

• Informal collaboration zones

• Amenity expectations

Real example from our projects:

In the Moves International office, we interviewed employees about:

• How customer service and operations teams interact

• Storage needs for client files

• Technology requirements

• Break area preferences

This input directly informed our space planning, ensuring the design supported actual work patterns rather than management assumptions.

Common Mistake #4: Not Considering Future Growth

Another common mistake is not considering future growth or changes in the business's needs, which can result in a design that quickly becomes outdated.

Growth considerations:

Spatial flexibility:

• Modular furniture systems

• Reconfigurable meeting spaces

• Technology infrastructure for expansion

• Adequate power and data points

Capacity planning:

• Additional workstations without major renovation

• Scalable storage solutions

• Meeting room capacity for growth

• Kitchen and amenity sizing

Technology future-proofing:

• Adequate electrical capacity

• Data cabling infrastructure

• AV system expandability

• Smart building integration potential

How we design for flexibility:

In commercial projects like Saravanaa Bhavan restaurants, we consider:

• Menu evolution requiring kitchen modifications

• Seating capacity changes

• Technology updates for ordering systems

• Regulatory changes in hospitality sector

As co-founder of Dezinery (Australia's marketplace for recycled and reusable homewares), I understand designing for longevity and adaptability, not just current needs.

Common Mistake #5: Failing to Prioritise Sustainability and ESG

Failing to prioritise sustainability, environmental responsibility, and ESG principles can lead to spaces that don't meet regulatory standards and therefore do not attract and retain socially conscious customers and employees.

Why sustainability matters in commercial projects:

Regulatory compliance:

• Building codes increasingly mandate energy efficiency

• Commercial buildings face stricter environmental standards

• Potential future carbon pricing

Client expectations:

• B2B clients increasingly require supplier ESG credentials

• Consumer awareness driving sustainable business practices

• Tender requirements often include sustainability criteria

Employee attraction and retention:

• Top talent prioritises environmentally responsible employers

• Workplace wellness linked to sustainable design

• Younger workforce particularly values ESG commitment

Operational benefits:

• Reduced energy costs (LED lighting 70% reduction)

• Lower water bills (WELS-rated fixtures)

• Decreased maintenance from durable specifications

• Enhanced property value

How we integrate sustainability:

Material specification:

• Low-VOC finishes for healthy indoor air

• Locally sourced reducing transport emissions

• Durable commercial-grade extending lifecycle

• Recyclable or biodegradable where possible

Energy efficiency:

• LED lighting meeting commercial lux requirements

• Natural light optimisation

• Energy-efficient HVAC where applicable

• Smart controls reducing waste

Waste reduction:

• Retain existing infrastructure where functional

• Upcycle furniture and fixtures

• Donate removed items for reuse

• Construction waste diversion targets

Example: In Saravanaa Bhavan restaurants, we achieved sustainability whilst meeting stringent food service requirements, and fire safety standards.
