Extradom is a popular real estate website that offers house plans. Nomtek worked with Extradom to create an iOS app that would help the company improve sales and gain a wider reach.

Extradom was founded in 2000 and has served over 100,000 customers to date. It’s one of the leading e-commerce websites selling house plans in Poland. Over the years, the company has grown to now provide comprehensive house-building services with a 3D project creator, custom house planning, land maps, and many more.

When reviewing analytics, the owners of Extradom discovered that a lot of the traffic was coming from mobile phones, with 90% from Android.

The customers could enter and browse the desktop website on a mobile phone, but Extradom wasn’t satisfied with the user experience and the lack of engagement opportunities in that approach.

To improve the user experience, reach a broader audience, and meet the growing traffic coming from mobile, Extradom decided to build a native mobile application for Android. 

The application would let customers browse through a vast database of house plans and customize their searches. Customers would also be able to contact a sales representative directly from the app to further discuss the details.

Scope of Work

Developing a native Android app for Extradom, we focused on enhancing user experience and sales through advanced search filters, seamless integration with Salesforce, and leveraging website analytics for optimized functionality.

Native Android App Development

Developing a native Android application in Kotlin optimized for user engagement and sales enhancement, allowing customers to browse a wide array of house plans.

Implementation of Advanced Features

Implementing advanced filtering options and direct sales capabilities, enabling users to easily find and purchase house plans. Integrating functionalities for account synchronization with the Extradom website.

Salesforce Integration and Data Utilization

Integrating the app with Salesforce for effective offer management and customize app features based on insights from website user analytics.


Extradom had loads of interesting data generated by the desktop website. Insight into user analytics helped us design and implement data-based functionalities that met the user demand instantly.

The Extradom app is integrated with Salesforce, where employees can manage and customize every offer.

From project workshops to application release, our team finished the application in seven months.

Extradom for Android lets customers browse through thousands of house plans and use advanced filters to narrow down their expectations. Customers interested in a particular house plan can call a sales rep to book the project directly from the mobile application.

Extradom was among the top 5 apps in the home & living category on Google Play. The app has over 50,000 downloads.

A year after the app release, Extradom and the company’s mobile app were sold to Domodi Group.
