Client story

Unlock Your Block, a subdivision and building specialist, wanted to make the complex process of property subdivision more understandable for their clients.

They partnered with 2410 to develop interactive calculators that visually matched their website and helped guide users through key financial decisions.

These tools provided instant feedback, helping property owners make better-informed choices before reaching out - creating a smoother, more transparent customer experience.

Project overview

Unlock Your Block, a leader in property subdivision and development, sought to enhance their online resources to better serve clients exploring subdivision opportunities.

In partnership with 2410, they embarked on a project to create interactive, user-friendly calculators tailored to the needs of property owners.

2410 designed and developed three responsive calculators that seamlessly integrated with Unlock Your Block's existing website, ensuring a consistent and engaging user experience. These tools featured dynamic result displays, allowing users to receive instant feedback on their inputs, thereby facilitating informed decision-making.

Beyond the core functionalities, the calculators were equipped with advanced features such as automated outputs to administrators and automatic Mailchimp list subscription. These integrations streamlined client communications and enhanced marketing efforts, positioning Unlock Your Block as a technologically adept industry leader.

The project unfolded in two phases: the initial development and styling of the calculators, followed by the integration of additional features and refinements based on client feedback. This iterative approach ensured that the final product was closely aligned with client expectations and user needs, ultimately contributing to a more engaging and informative online presence for Unlock Your Block.

Great work 2410. Thanks for your expertise! The calculators worked well and matched the brand’s requirements. Multiple rounds of changes were addressed professionally. Communication could be slightly more responsive during revision phases, but overall very satisfied.
