Buying process

Off-plan means buying
a description of a building.

Most London new-build is sold before it is finished, so for our buyers this is not an exotic option but the normal one. That makes it worth understanding properly rather than avoiding, and the honest version has four things that can move and five that hold still.

What can move

Four things that are
not settled yet.

None of these is a scandal and none is hidden. They are the ordinary consequences of paying for something that does not exist yet, and each has a question that gets you a written answer.

The completion date is an estimate

Construction slips for reasons nobody in the transaction controls. The date you are given at reservation is an expectation, not a promise, and it can move by months.

Worth asking

What is the anticipated date, and separately, what is the backstop date in the contract after which I have rights?

The specification can move within limits

Materials, layouts and finishes may be altered. Most changes are minor and permitted by the contract; a significant one can give you a right to cancel.

Worth asking

What is fixed, what may change, and what counts as significant enough to give me an exit?

What surrounds you may not exist yet

In a phased development the view, the courtyard and the shops are often later phases. You are buying into a plan as much as a building.

Worth asking

What is consented next to this plot, what is under construction, and when does each phase land?

Your funding has to survive the wait

A mortgage offer is issued with a validity period, and a long build can outlast it. Currency can also move a long way between reservation and the completion payment.

Worth asking

If completion is far out, when would an application realistically need to be made?

What holds still

Five things that do not
depend on goodwill.

Off-plan is not a leap of faith. The protections are documentary, and each one is a specific thing you can ask to see before you pay anything.

The contract, not the brochureEverything that binds anyone is in the contract and the reservation agreement. Renders and floorplans are marketing; the documents are what you can hold someone to. The questions to put in writing →
The backstop dateA long-stop date is the point after which delay stops being your problem to absorb. It is the single most important date in an off-plan contract and it is not the one in the brochure.
A new-home warrantyNew homes are normally sold with a warranty covering the structure for a period, and cover during construction in some circumstances. The provider, the length and exactly what is covered are in your documents rather than on this page.
Your solicitor on the depositAsk where your money sits between exchange and completion and on what terms it is held. This is a question with a documented answer, and it is your solicitor’s to give. Who does what →
Timing you can still controlThe funding and AML sides are the parts of the wait that are yours. Started early they are administration; started late they are the reason a deadline is missed. Source of funds, prepared →
Being fair about it

This is not a warning
against buying off-plan.

It would be easy to write this page as a list of dangers and finish by suggesting you buy something completed instead. That would be dishonest, because almost the entire London new-build market is sold this way and because buying early is how buyers get first choice of plot at a price fixed before the rest of the phase is released.

What we will not do is pretend the trade is free. You are accepting timing risk and specification risk in exchange for choice and a fixed price. Whether that trade suits you depends on your horizon and how much certainty you need, which is a conversation rather than a rule.
