New Build Scheme Data

A from-price tracks the cheapest remaining unit, not the market

Almost all scheme marketing quotes a price "from" a figure. That figure is the cheapest currently available unit.

So it moves for two very different reasons, and they look identical in a series:

• The cheapest units sold, so the from-price rises with nothing repriced.
• Units were actually repriced.
• Or a new phase released with different stock, which can move it either way.

We deliver price_is_from as a constant true on scheme records, with from_price_movement_cause as not_determined, and from-prices are excluded from average asking-price figures by default.

Where plot-level pricing is published, plot_price gives the real series — and where it is not, we say the from-price is the only figure available and what that limits.

Plot-level is the good case

Some developers publish a plot or unit grid with individual prices and availability. That is the best version of this data: plot_id, plot_price, plot_status and plot_type, which gives real price movement and real sell-through separately.

Phases, incentives and completion dates

Phases are supply events

A phase release adds inventory without a new scheme appearing. phase_identifier and phase_release_event are recorded, because in a feed without them a phase release looks like either nothing or a new development.

Incentives sit outside the price

New build marketing frequently carries incentives — contributions to costs, included fittings, part-exchange arrangements — that change the effective transaction without changing the quoted price.

That is the same structure our Apartments.com page describes for rental concessions: the headline stays flat while the real deal moves.

incentive_text is captured as published and incentive_value only where a figure is stated. No effective price is computed, because incentive eligibility and value depend on buyer circumstances we cannot observe.

Completion dates

completion_stated as published, flagged as a projection. A stated completion date is a developer's expectation, not a commitment, and a dataset treating it as fixed inherits a forecast.

What we do not collect

Units sold or reserved beyond published availability, developer financials, buyer or reservation data, or an effective price computed from an incentive.
