Offsite Manufacture Design Freeze Preparation Checklist

Ask when the design freeze falls and what triggers it, and put that date in your own calendar rather than relying on being reminded of it.

It usually arrives earlier than owners expect, and the difference between expecting it and being surprised by it is entirely a matter of preparation.

Ask which party sets the freeze date, whether the manufacturer, your designer or a contractor, and record who has the authority to move it.

A date owned by somebody who is not in your weekly conversation is a date that moves without you hearing about it.

Ask exactly which parts of the design freeze at that point and which continue to be developed, since the two are rarely separated clearly.

Owners often assume everything freezes, then relax about the parts that did, and are caught out by the parts that did not.

List the decisions that belong to your household rather than to the design team, and mark which of them have to be settled before that date.

Nobody else on the project will separate your decisions out for you, and they are the ones most likely to run late.

Ask whether any decisions are needed before the freeze itself, since some information has to travel through other parties before it reaches the factory.

The real deadline for a household is often well ahead of the one named on the programme.

Agree how and by whom you will be told that a decision is outstanding, and how much notice you can expect before it becomes a problem.

The person who knows what is missing and the person who can supply it are frequently not speaking to each other.

Ask which finishes, linings and fittings are applied in the factory rather than on site, and treat that list as your early decision list.

The list varies considerably between manufacturers, and assuming it is short is the commonest way a household falls behind.

Ask when socket, switch and outlet positions have to be settled, and whether any of them can be altered once a unit has been built.

These are decisions households usually make late, standing in the space, and this is exactly the kind that moves earliest.

Settle the layout of anything involving water well before the freeze, since those positions usually sit deepest in a factory-made unit.

Layouts under discussion at the freeze become layouts decided by somebody else, and the household rarely likes the result.

Ask to see physical samples rather than images for anything you are choosing early, and record what you were shown and when.

Choosing from an image is how a household ends up surprised by something that can no longer be changed.

Get everyone whose opinion matters into the same conversation well before the freeze, rather than discovering a household disagreement once the design has closed.

Late household disagreement is ordinary on any project and unusually costly on this one, because the remedy no longer exists.

Record each decision with the date it was made and who confirmed it, so a later dispute about what was agreed has something to refer to.

A dated decision log is worth far more on a project with an early freeze than on one where everything stays adjustable.

Ask what the payment stages are and what each one is tied to, and put the answer to a suitably qualified adviser before you commit.

The shape of this arrangement differs from a site-built project in ways that are easy to miss until they matter.

Payment and contract arrangements are legal matters. Have anything you are asked to sign reviewed by a suitably qualified adviser.

Ask who owns the units while they are still in the factory or in storage, and at what point ownership is understood to pass to you.

This is a question owners rarely think to ask and every adviser asks immediately, which tells you something about its importance.

Ask who insures the units before they arrive, and whether your own policy is expected to cover anything at any point.

Gaps between two insurance arrangements are found by accident, and finding this one in advance is straightforward.

Ask your lender how they treat payments for work carried out away from the site, and record their answer before any payment falls due.

Lender arrangements commonly assume work is visible on a site, and the mismatch surfaces at the least convenient moment.

Ask what would happen to units already made if the project stalled, and record what you are told rather than assuming the answer.

It is an uncomfortable question and the only sensible time to ask it is before anything has been made.

Ask whether units may be stored before delivery, where, and for how long they are expected to sit there.

Storage arrangements affect condition on arrival and are rarely mentioned unless somebody asks about them.

Ask how firm the delivery slot is, what would move it, and what happens to everything downstream if it does.

The slot binds several other parties, and owners are usually the last to hear that it has changed.

Write down what the site has to be ready for on the day, and confirm who is responsible for each part of that readiness.

Readiness is a shared obligation that nobody owns in full, which is how an arrival day goes wrong.

Describe the approach route in words, noting narrow turns, low bridges, weight restrictions and overhanging trees, since only someone local can supply this.

A written description of the approach is genuinely useful to whoever is planning the delivery and is almost never written down.

Ask who arranges any permission needed to use or close part of a road or footway on the day, and confirm it with your local authority.

This task is commonly assumed by everybody and held by nobody, which is exactly how it gets forgotten.

Anything affecting a public road or footway must be confirmed with the relevant local authority, who alone can say what is required.

Tell neighbours what is expected to happen and roughly when, since a delivery of this kind is far more visible than ordinary site traffic.

A short conversation beforehand converts a complaint into a courtesy, and the owner is the right person to have it.

Ask what conditions would cause a delivery to be postponed and who makes that call, and record the answer before the day approaches.

Owners plan around a delivery in ways that are hard to unwind, so knowing the grounds for postponement in advance is worth the question.

Ask which parts of the building are completed on site after delivery, and treat that list as where the remaining programme actually lives.

Owners assume the delivery is most of the work and are surprised by how much of the calendar sits after it.

Ask which party carries out the connections between units and at the base, and whether that is the manufacturer or somebody else.

Almost all of the structural work on site happens at these connections, so knowing who does it matters.

Ask what becomes unreachable at the moment units are joined, and whether anything is checked or recorded before that happens.

Spaces created where units meet are closed from both sides at once and are not inspectable afterwards.

Ask who is responsible for the surface the first units are set on, and what the manufacturer assumes about it.

Everything above inherits that plane, and the responsibility for it often sits with a different party from the units themselves.

Ask where services are joined between units and whether access to those points remains available once the building is finished.

Access provision has to be designed into a unit rather than added later, which makes it a question for now.

Ask which finishing work is left to you or to trades you appoint separately, and when each of those would need to start.

Owners commonly discover a gap in scope at this boundary, and it is easiest to close before anything is ordered.

Ask what tolerances the manufacturer works to and how those relate to what is done on site, without treating either as a promise about appearance.

Owners judge a finished building by eye, and the vocabulary for that judgement is worth establishing early.

Tolerance is a technical matter set by the design and the manufacturer's information. Nothing here states what any tolerance should be.

Ask where accumulated variation tends to become visible in a finished building of this kind, and what is considered ordinary.

Knowing in advance where to expect it prevents an ordinary characteristic being reported as a defect.

Ask which things, once built into a unit, cannot be corrected on site at all, and keep that list where the household can see it.

This is the list that makes the freeze feel real to a household, and it should be shown rather than described.

Ask whether anything inside a finished unit can be adjusted after it arrives, or whether the interior is effectively closed.

Owners often expect a period of adjustment after delivery that does not exist in this way of building.

Ask what you would need to know before fixing anything to a wall or ceiling later, and what record of the unit's make-up you will receive.

Hanging a shelf is an ordinary household act, and in a factory-made unit it depends on information only the manufacturer holds.

Do not fix into a factory-made wall or ceiling without establishing what is behind the lining. That information comes from the manufacturer and a qualified professional.

Ask what altering, extending or opening up the building would involve later, and record the answer for whoever considers it.

A future owner will assume the building behaves like any other, and the record is the only thing that tells them otherwise.

Ask how a change is formally requested after the freeze, who considers it, and how long you would wait for an answer.

Knowing the route before you need it is the difference between a request and an emergency.

Ask what effect a change would have on the manufacturing slot and the delivery date, and record the answer in general terms.

The programme consequence is usually larger than the change itself, which is the part owners find hardest to anticipate.

Ask who is entitled to instruct a change and whether anything you say in conversation could be treated as an instruction.

Casual remarks on a site visit have become instructions on plenty of projects, and clarity here protects everyone.

Ask how you would be told if another party requested a change, and whether your agreement is needed before it proceeds.

Changes originating elsewhere reach an owner late, and the arrangement for hearing about them is worth agreeing.

Keep your own log of every change discussed, agreed or refused, with dates, rather than relying on a record held by another party.

Your own log is the one you can still find in several years, and it is the only one written from your point of view.

Decide in advance which decisions you will not reopen once made, and tell the household, so the freeze is respected from your side too.

Owners are often the source of late change, and stating this intention openly makes it far easier to hold.
