Greenfield factory: building the plant your process wants, and carrying everything that comes with starting from nothing

The freedom is real and it is the only reason to do it

Processes with awkward physical demands — very heavy equipment, unusual height, long uninterrupted runs, stringent contamination control, heavy utility loads, high vehicle throughput — are compromised in any building designed for something else. On a clear site those demands set the design. The corollary is that if your process fits comfortably in ordinary industrial stock, the freedom is worth much less, and you are paying schedule and risk for flexibility you will not use. The honest test is to write down what the building must do that a standard unit could not, and see how long the list is.

The critical path runs through people who do not work for you

Land acquisition, planning or zoning consent, environmental approvals, highways and access agreements, and connections for electricity, gas, water and drainage each move at their own pace. Grid connection in particular has become a limiting factor in many industrial regions, with queues measured in years for significant loads. None of these respond to project pressure, and several can refuse. Establish the approval and connection position before committing capital, and build the programme backwards from the slowest of them rather than forwards from when the building could be constructed. Treat each of them as a gate with a named owner and an evidenced date rather than an assumption sitting inside a bar on a programme chart.

Site risk transfers to you the moment you buy

Ground conditions, drainage, flood exposure, ecology, archaeology and access all become your problem once the land is yours, and each can add cost and time after the price has been agreed. Thorough investigation before purchase is the only protection, and it costs a fraction of what a surprise costs afterwards. A greenfield site carries no inherited industrial contamination, which is a genuine advantage over a previously used site, but it can carry constraints that are just as expensive — a protected habitat, a watercourse, an unstable substrate or an access road that cannot take your vehicles.

You are starting an organisation, not commissioning a building

The building is only part of what has to exist on the first production day. A workforce has to be recruited and trained where none existed, supervision and maintenance capability built, local suppliers and contractors identified, customer approvals and any site-specific registrations obtained, and a quality system demonstrated in operation rather than on paper. This is where new plants most often disappoint against plan: the equipment works and the output does not arrive, because the organisation running it is new. Budget a ramp and the experienced people to lead it, transferred from an existing operation if you have one.

How this compares, without a verdict

New build and existing premises answer different questions, and neither is generally the better option. A new build suits a process with genuine physical demands, a long expected life, a location decision driven by labour or market access, and an organisation with capacity to run a construction programme alongside its day job. Taking existing premises suits speed, capital preference and processes that fit standard buildings. Structural, civil, services and safety design across any new build sits with the appointed engineering team working to local codes; the client's job is a brief that describes the process honestly.

Frequently asked questions

How much expansion land should we buy with a new site?

Enough to accommodate the growth you can articulate a reason for, plus the yard and circulation that growth would need, which is the part usually forgotten. Land costs least at the moment you buy the original plot and often unavailable later at any price, because the adjoining parcels get developed. Against that, land carries holding costs and can attract site coverage conditions. Set the answer against a specific expansion scenario rather than an open-ended wish for room.

Should we design the building around the equipment or select equipment to suit a building design?

On a new site the equipment should lead, since that is the advantage you are paying for, but only where the equipment decision is genuinely settled. Where technology choice is still open, freezing the building around a specific machine that later changes is a common and expensive error. The usual approach is to fix the demanding constraints — height, floor capacity, services capacity, bay dimensions — with headroom, and leave the detailed fit-out until the equipment is contracted.

What incentives are typically available for new industrial sites?

Many regions offer support for industrial investment through development agencies, and the forms vary widely: serviced land, capital grants, training support, planning assistance, or infrastructure provision. What matters practically is that these come with conditions, usually about employment, timescales and clawback if commitments are not met, and that they take time to negotiate. Engage the relevant development body before the site is selected, since the strongest support is generally attached to locations they are actively promoting.
