My Contribution

Identified homeowners’ frustrations through research and designed a streamlined search solution that helped UK customers find tradespeople faster and more efficiently.

Final Impact

The Problem Space

Homeowners wait 1–2 days for tradespeople to respond, causing frustration and delays.

Our Solution

We enabled them to search and message tradespeople directly, cutting the wait time to just 5–10 minutes.

So, how did I get there?

Overview

OSST is a UK-based platform that connects homeowners with over 3 million skilled renovation tradespeople. It streamlines the search and communication process, making it easier for both sides to connect efficiently.

Competitor Analysis

To better understand the market landscape and identify improvement opportunities, I conducted a competitor analysis of similar renovation platforms in the UK.

User Journey Map

After analyzing competitors, we interviewed UK homeowners and mapped out their renovation journeys.

The insight I got from the above research:

The insight I got from the above research:

Current Situation

How we improved it?

Search problem

Most platforms ask users to post a job and wait for responses.

Allow users to quickly search for the right professionals

Messaging problem

Half of the platforms don’t offer in-app messaging—only phone or email.

Enable direct in-app messaging for faster communication

Project tracking problem

Project tracking isn’t supported on UK platforms—only available in the U.S.

Project tracking deprioritized (not feasible)

Why it’s not feasible:

Older users prefer face-to-face communication.

Project tracking requires high development effort.

Renovation projects are too unique for standardized tracking.

Turning Insights into Concepts

  1. Approaches for searching tradespeople

Plan A: The system matches tradespeople after homeowners post a job with their details.

Plan B: Remove the job posting step, allowing clients to search and filter tradespeople on their own for a more personalized discovery process. (Selected)

We chose Plan B because user research revealed that the system’s matching process often failed, requiring multiple attempts to get a suitable response.

  1. Approaches for keeping communicate

Plan A: Facilitate real-time interactions by introducing live chat capabilities.(Selected)

Plan B: Create a client portal to schedule a inquired call or meeting.

We chose Plan A because users found real-time chat to be the easiest and fastest way to communicate.

Design Flows

From initial

To iteration

We improved:

  1. Adding decision nodes gives users more control, like choosing to check messages before searching.

  3. Bookmarking makes it easy to revisit preferred tradespeople.
