How Castle Green Homes increased upgrade revenue by 41.7% with a digital housetype configurator

Choosing upgrades should be one of the most engaging parts of buying a new-build home.

For the buyer, it is the point at which the property begins to feel like their home.

But there is a fundamental challenge.

A kitchen worktop sample can show a buyer a finish.

A cabinet door can show them a colour.

A specification sheet can tell them what is included.

None of those things show the buyer what those choices will actually look like together, inside their home.

That gap between choosing something and understanding it created friction.

Buyers could leave appointments unsure about their selections. Choices were revisited. Options had to be explained again. Conversations restarted across different appointments and touchpoints.

Some decisions were delayed.

Others were simplified.

And potential upgrade opportunities could be lost, not necessarily because buyers did not want them, but because they could not confidently visualise what they were buying.

For the sales team, every repeated conversation also meant additional administration.

At a small scale, those inefficiencies can be manageable.

As housing output increases, they multiply.

More homes mean more buyers, more upgrade conversations, more selections to record and more decisions to manage.

Castle Green Homes needed an upgrade journey capable of growing with the business without requiring manual administration to grow at the same rate.

Castle Green Homes did not need to sell upgrades more aggressively.

It needed to make them easier to understand.

Working with EyeSiteView, Castle Green introduced a digital Housetype Configurator into the buying journey.

Instead of asking customers to build a picture of their finished home from individual samples and specification sheets, the configurator allows upgrades to be explored visually within the context of the buyer’s specific housetype.

Choices become something buyers can see rather than simply imagine.

Different options and finishes can be explored and compared visually, helping customers understand how individual decisions work together throughout their home.

More importantly, the experience does not have to end when the sales appointment does.

Selections can form part of a connected digital buying journey, giving buyers greater continuity as they move between the sales centre and their customer portal.

The upgrade journey becomes an ongoing digital experience rather than a series of disconnected conversations.

What changed for the buyer?

Before digitisation, buyers were often required to make decisions based on individual samples and their own imagination.

The configurator changed the context in which those decisions were made.

Instead of asking:

“What will this worktop look like with those cabinets?”

Or:

“Will that finish work in my kitchen?”

buyers can explore those choices visually within the home they are purchasing.

That greater context helps turn an abstract upgrade into something tangible.

Customers can better understand what they are choosing, compare alternatives and return to their decisions as their purchase progresses.

The objective is not to create pressure to spend more.

It is to give buyers enough clarity to make confident decisions.

What changed for the sales team?

The impact extended beyond the customer experience.

Previously, knowledge about selections could sit across conversations, paperwork and individual appointments.

As buyers reconsidered decisions, sales advisors could find themselves returning to earlier discussions, re-explaining options and manually updating selections.

Digitising the process created a more consistent framework for managing those decisions.

The technology supports the repetitive elements of the upgrade journey, while the sales advisor remains focused on the areas where their expertise adds the greatest value.

Instead of technology replacing the sales conversation, it supports it.

Buyers arrive at conversations better informed.

Choices have greater context.

Selections can be carried forward.

And sales teams can spend less time reconstructing previous conversations.

For a growing housebuilder, that distinction matters.

Increasing housing output should not automatically mean increasing repetitive administration at the same rate.

The commercial impact was significant.

But the result is important for another reason.

The increase did not come from simply putting more upgrades in front of buyers.

It came from improving the environment in which those decisions were made.

By removing friction from the process, Castle Green made it easier for customers to make informed choices about the home they were already buying.

From an upgrade tool to scalable digital infrastructure

The value of digitising the upgrade journey becomes even greater as a housebuilder grows.

A manual process that works across a small number of developments can become increasingly difficult to manage as volumes rise.

More developments create more customers.

More customers create more upgrade conversations.

And more conversations create more selections, records, follow-ups and administration.

Digital infrastructure changes that relationship.

The same underlying process can support more homes, buyers and sales teams without requiring every additional interaction to be managed manually.

For Castle Green Homes, the Housetype Configurator now provides a consistent digital framework for how upgrades can be presented, explored and progressed.

For customers, it means greater continuity between the sales centre and their wider digital buying journey.

For sales teams, it creates a clearer and more consistent way of managing upgrade decisions.

For the business, it provides an upgrade process designed to support growth rather than become more difficult to manage because of it.

What began as an opportunity to improve the customer experience has therefore become something much more commercially significant:

A scalable part of Castle Green Homes’ digital sales infrastructure.

What can other housebuilders learn from Castle Green Homes?

Options and extras can represent a significant source of additional revenue for housebuilders.

But maximising that opportunity does not necessarily mean selling harder.

The Castle Green Homes experience demonstrates the value of making complex purchasing decisions easier for buyers to understand.

When customers are asked to imagine an unbuilt home, uncertainty creates friction.

The same principle applies to upgrades.

Showing a buyer a sample tells them what an individual product looks like.

Showing them that choice inside their future home gives it context.

Connect that experience to the wider buying journey and the benefits extend beyond visualisation.

Decisions can become easier to manage.

Information can move with the customer.

Repetitive administration can be reduced.

And the process becomes more scalable as housing output increases.

For Castle Green Homes, that shift contributed to a 41.7% increase in options and extras and millions in additional revenue.

The technology did not change what Castle Green was selling.

It changed how easily buyers could understand, choose and progress it.
