Introducing House Price Derry: a local house-price guide

We're introducing House Price Derry, a free online house-price guide built by Blue Canvas for homeowners in Derry and the surrounding area.

The question behind it is familiar: what might my home be worth, and where should I start? House Price Derry brings a property estimate, local market guides and an explanation of the data into one place. It is a starting point for research, not a replacement for someone inspecting your home.

A local tool for a local question

The calculator accepts postcodes in BT47, BT48, BT49 and BT82. Visitors enter their postcode, house number or name and property type, with optional details to describe the property further.

A name and email address are required to see the estimate and receive the report. The site explains the report request and follow-up choices as part of that journey. Visitors should review those choices before submitting their details.

The aim is to make the first stage of property research more approachable. Alongside the calculator, the site brings together Derry house-price information and a guide to online estimates and in-person valuations.

What sits behind the estimate

House Price Derry uses official UK House Price Index benchmarks for Derry City and Strabane, together with Northern Ireland property-type data. Its published methodology explains how those figures are used and where the model has limitations.

These are modelled guide ranges based on area-level information. They are not verified sale prices for a particular house or street. A postcode match does not mean the property has been inspected, and homes outside the Derry City and Strabane district need particular care when comparing local prices.

The result is not a formal RICS valuation and should not be used for mortgage, legal, tax or investment decisions. A local estate agent or qualified surveyor should inspect the property before a major decision.

Why we built it

At Blue Canvas, we work on a practical problem: turning information or an existing process into something people can use. Sometimes that means staff training or workflow automation. Sometimes it means building a focused website or digital product.

House Price Derry is an example of the latter. The useful work is not simply putting a calculator on a page. It is deciding which question to answer, explaining the evidence behind the result and giving the visitor a sensible next step.

That approach applies to other businesses too. A price guide, product selector, booking journey or customer portal can be more useful than another page describing a service. The starting point is the task your customer is trying to complete.

Clear rules before clever technology

A data product does not need AI in every step. Calculation rules and source checks should be explicit and reviewable. AI-assisted work is a separate design decision, with its own permissions and human checks.

For businesses exploring that next step, our independent ChatGPT Dots guidance covers workflow readiness, staff training and controlled pilots. It is a Blue Canvas consultancy resource, not an OpenAI service or an endorsement from OpenAI.
