Which is the best procurement route for office fit‑out in the UK?

Why Most UK Businesses Benefit from Design & Build

The industry still debates procurement routes as if nothing has changed in the last decade. But for most SMEs, corporate occupiers, agents and PMs, Design & Build (D&B) consistently delivers the best outcome — and that’s based on real project delivery, not theory.

The Limitations of Traditional Procurement Routes

Traditional procurement still has a place, but it’s often misapplied. When you separate designer, QS and contractor, you create a process that looks structured on paper but quickly becomes fragmented in practice:

• No cost clarity until tenders land

• Early design work that becomes unaffordable

• Slow re‑tendering cycles when budgets don’t align

• Design intent diluted as it passes through multiple hands

• A lack of clear ownership when issues arise

These aren’t minor inefficiencies — they’re structural weaknesses that impact cost, speed and quality.

Where Traditional Procurement Still Works

To be fair, traditional procurement does have a legitimate role.

For large‑scale, low‑design, heavily technical or infrastructure‑led projects, the separation of roles can be appropriate. When the brief is more about engineering, compliance or long‑term phased works — and less about brand, experience or culture — traditional routes can be the right tool for the job.

But those projects are the exception, not the norm.

The Challenges of Construction Management Models

Construction management can be quick to get moving, but it carries its own risks:

• Cost creep when site conditions change

• Delays when information isn’t 100% correct

• No single party responsible for the information

• Greater exposure for the client

Without a contractor taking ownership — or a competitive tender process to flush out risk — clients often carry more uncertainty than they realise.

Why Design & Build Creates Better Outcomes

D&B works because the team is aligned from day one.

Designer, fit‑out specialist and furniture expert working as one unit — not three separate entities trying to stitch a project together after the fact.

A great example is Killstar Brighton. Tight timeframe, limited budget, strong brand expectations. Under a traditional route, cost alignment and design intent would have been a battle. Under D&B, the team delivered a fully branded space, on time and within budget, because the people designing it were the same people responsible for building it.

Faction Interiors’ Enhanced D&B Model

This is where Faction’s approach goes further.

We don’t run a generic D&B setup.

We bring specialist designers and furniture experts as distinct entities within the D&B structure, giving clients 100% expertise from the outset.

• No generalists pretending to be specialists

• No handovers to people who weren’t in the room at pitch stage

• The team you meet at the start is the team that delivers the project

It’s the best of both worlds:

• The creativity and depth of a specialist design studio

• The accountability, speed and cost certainty of D&B

• A single team responsible for the outcome

The Bottom Line

The industry will keep debating procurement routes for years. But from where I’m sitting — having delivered projects across multiple models — the answer is clear.

If you want clarity, accountability and a space delivered exactly as planned, Design & Build is the route that actually works for most UK businesses.
