At Faction Interiors, we take a design-led, methodical approach to fit-out and refurbishment, focused on making your budget go further, without compromising on quality.

What Sets Faction Interiors Apart
Design-Led, Without the Price Tag
There’s a common assumption that to achieve a high-end result, you need to appoint a large design practice.
In reality, that often means:
Higher fees
More layers
Less direct control
We do things differently.
We work with a trusted network of designers, project managers and specialist subcontractors, bringing together the right people for each project.
👉 The result:
Strong design
Practical delivery
Better value
Making Your Budget Work Harder
Every project has a budget. The difference is how far it goes.
Our focus is on:
Smart design decisions
Efficient delivery
Clear cost control
We don’t just deliver what’s asked, we push the brief further, finding ways to achieve more within the same budget.
A More Joined-Up Process
With in-house project management, design coordination and delivery, we remove unnecessary layers.
That means:
Clear communication
Faster decision-making
Better control of quality
And importantly:
👉 The price you pay reflects the work being delivered, not inflated margins through multiple tiers.
Easy to Work With
This is something clients consistently say after working with us.
We bring:
Structure
Clarity
A calm, methodical approach
We keep clients close to the process, cutting through the noise and making sure you understand what’s happening at every stage.

Our Approach to Fit-Out & Refurbishment
1. Understand What Actually Matters
Before design starts, we focus on:
How your business operates
What’s not working in your current space
What success looks like
This ensures the end result isn’t just visually strong, but genuinely functional.
2. Design With Purpose
We develop layouts and concepts that:
Reflect your brand identity
Support how your team works
Balance collaboration and focus
Always with a close eye on cost.
3. Plan Properly
Our pre-construction approach is detailed and methodical, covering:
Surveys and building constraints
Programme planning
Cost validation
Risk management
This is where projects are won or lost.
4. Deliver With Control
On site, we focus on:
Quality
Programme
Coordination
Whether working in a live environment or a vacant space, the aim is simple:
👉 Deliver the project properly, without unnecessary disruption.
Common Misconceptions About Fit-Out
“You need a big design practice for a high-end result”
Not necessarily.
With the right team and approach, you can achieve a design-led, high-quality space without excessive overheads.
“Cheapest price wins”
In reality, the cheapest route often leads to:
Compromised quality
Variations later
Programme issues
We focus on delivering value, not just cost.

Got it — shifting this from a “services page” into a proper guide that still sells Faction subtly. This will rank better and build authority.
Office Fit-Out & Refurbishment Guide (London & South, 2026)
A Practical Guide to Getting It Right First Time
Planning an office fit-out or refurbishment in London, Brighton, Croydon, Portsmouth or Southampton can feel overwhelming.
There’s a lot to balance:
Budget vs quality
Design vs practicality
Programme vs disruption
Get it right, and you create a space that genuinely improves how your business operates.
Get it wrong, and it becomes expensive, slow, and frustrating.
This guide breaks down how fit-out and refurbishment projects actually work, what to expect, and how to make better decisions from the outset.
Fit-Out vs Refurbishment: What’s the Difference?
Office Fit-Out
A fit-out is about turning a space into a working office.
This could be:
A new lease
A stripped-out shell
A CAT A space needing full CAT B works
It includes:
Layout and partitions
Finishes and branding
Furniture and workplace setup
Office Refurbishment
A refurbishment upgrades an existing space.
Typically involves:
Reconfiguring layouts
Replacing finishes
Improving lighting, acoustics and flow
For many businesses, refurbishment is now the preferred route, especially with hybrid working reducing space requirements.
Why Businesses Are Investing in Their Workplace
Across London and the South, most projects are driven by:
Hybrid Working
Offices need to offer something different to home. That means better collaboration spaces and more flexibility.
Better Use of Space
Many businesses are reducing footprint but improving quality.
Staff Experience
A well-designed office helps attract and retain people. Poor environments do the opposite.
The Fit-Out & Refurbishment Process (Step-by-Step)
1. Define the Brief Properly
This is where most projects either succeed or fail.
Key questions:
How many people will use the space?
How do they actually work?
What isn’t working in the current setup?
If this isn’t clear, everything that follows becomes harder and more expensive.
2. Understand the Building
Before design progresses too far, the space needs to be assessed:
Existing services (M&E)
Structural constraints
Ceiling voids
Access and logistics
This is where risks are identified early, not during construction.
3. Set a Realistic Budget
Fit-out and refurbishment costs vary depending on:
Specification
Condition of the building
Programme
Location
4. Design & Space Planning
This stage shapes how the space will function day-to-day.
It typically covers:
Desk layouts and ratios
Meeting rooms
Breakout and collaboration areas
Circulation and flow
The best designs balance:
👉 brand identity
👉 practicality
👉 cost
5. Pre-Construction (Where Projects Are Won or Lost)
A detailed pre-construction phase includes:
Programme planning
Cost validation
Design coordination
Risk management
This stage removes uncertainty and prevents issues later.
6. Construction & Delivery
On site, success comes down to:
Coordination of trades
Quality control
Programme management
For refurbishment projects, especially in occupied spaces, this also involves:
Phasing works
Managing disruption
7. Handover & Completion
Before completion:
Snagging is carried out
Systems are tested
Final finishes are reviewed
A structured handover ensures the space performs as intended from day one.
Common Mistakes to Avoid
These come up time and time again:
Rushing into construction without proper planning
Choosing based on lowest price
Underestimating building constraints
Overcomplicating design without considering budget
Lack of clear decision-making
Avoiding these is often the difference between a smooth project and a difficult one.
A Common Misconception: “You Need a Big Design Practice”
Many clients assume that achieving a high-quality, design-led office requires a large design consultancy.
In reality:
This often adds cost and complexity
Doesn’t always improve the outcome
A more effective approach is:
Working with the right designers for the project
Keeping delivery practical and focused
Making the budget work harder
What Makes a Successful Fit-Out or Refurbishment?
From experience, the best projects share a few things:
A clear, well-defined brief
Strong pre-construction planning
A practical, buildable design
Good communication throughout
A team that understands both design and delivery
