About Byggmax

About Byggmax

The first Byggmax store opened its doors in 1993. Byggmax primarily serves private consumers and in the assortment, customers will find works, board material, garden products, tools, paint, tiles, and much more for the most common home improvement projects. Byggmax has established a strong market position on the do-it-yourself market in Sweden, Norway, Finland and Denmark. There are currently 127 Byggmax stores in Sweden and that number continues to grow.



Our case was to research and create prototypes of a calculating tool that measures the quantities of material consumption during a construction project. This tool was to be available to at-home builders and had to fit within a frame that Byggmax wanted us to operate within.

Frame of the product

  • What would this calculator look like?

  • How would it work?

  • Where in the user journey would it be needed?

  • What would be the outcome if Byggmax implemented the proposed solution?

  • Target group: at-home builders (Beginners)

  • The user must have done their research.

  • It should be easy to maintain.

  • It shouldn’t be connected to the range of products.

Our Method

Our method

Design Thinking was the method we used to work on this case and it helped us gain knowledge about the target group. We could propose different solutions to our design questions and create the best possible prototypes that worked within the given frame. It also allowed us to test our prototypes and draw conclusions about the results we achieved with testing. This was presented for Byggmax and the case material was handed over for future implementation.



​The external research was done by looking at how others have solved similar problems we were facing. We were looking for inspiration and similar tools. Our team joined and looked through some groups on social media to get a sense of what problems are most common for beginner builders. After gathering all of this data, we went into creating Personas and User journeys.



User Journey



We identified the needs of our target group as:

Help to think

Someone to reason with - based on the special conditions of their project.​

Help to visualize

Make a drawing of the project

Help to calculate

Help with calculating area and cost


Based on the user journey, we created different hypotheses about where users could meet the calculating tool.

  • Above all, the optimist wants to be able to reach the tool through the product side when they want to calculate the cost

  • The planner who has already found all the material wants to be able to reach the tool through the start page to double-check calculations

  • And the beginner who wants more personal help throughout the project and could meet the multiplication tool through it.

Design questions

1. How can we offer beginner support and help in every part of the project?
2. How can we help the optimist and planner in particular to calculate material consumption?


We generated a lot of different ideas by having workshops where we let our creativity go wild, from there we scaled down based on what impact the solution had and how easy was it to implement it into a prototype. This creative chaos led to 2 different prototypes that we thought really answered our design questions.


The first prototype was the material calculator that Byggmax asked for. We knew this was a quite complex tool and simplicity was the key in our opinion. Users would need this tool to be easy-to-use so they could calculate the material consumption. Based on our research, this prototype would mostly be used by optimistic and planning users.


The need for our second prototype was discovered when we spoke to beginner at-home builders that mentioned their need for support in several stages of the project. They crave someone they can talk to, who has the experience and can guide them through their building project. Discovering that need, we had to come up with creative solutions that led us to build a prototype that could work as some sort of guidance.



Quantity Calculator


Measuring the quantity of paint needed to cover x amount of walls.
Note: if you are interested in seeing more, let me know. We have in total created 5 calculators that specialize in different measuring techniques.

Building Buddy

How this prototype works
  • Personal help is important.

  • Someone to brainstorm ideas with. Not just a chatbot.

  • It is important to be able to get professional help and not just turn to customer service.

  • Father-in-law could be replaced by a building buddy.

  • It is important that the help is: comprehensive, visible and easily accessible.

  • The user must have control over how they use the service.

  • The design is meant to be minimalist. As little distraction as possible.

  • Feedback in each step.


Testing with users

Testing was done on our first low-fidelity prototype to ensure users understood the service's fundamental idea.

At-home builders were used for prototype testing, with whom we had close dialogue.

Feedback from tests was used to identify areas that required improvement and presented to Byggmax.

This stage helped us uncover unknown unknowns, allowing for more effective shaping of the product to meet user needs.


Values & Takeaways

We designed 2 products successfully through a process we learned.

Valuable insights were collected and provided to Byggmax for further studies.

This case helped me develop the way around Design Thinking and see it as an iterative process, rather than linear.

Combining research, analysis, ideation, prototyping, and testing came naturally to me and enhanced my understanding of UX.


Lessons learned: Reflecting on Design Thinking

  • Design Thinking is an eye-opening journey that requires jumping between stages for innovative solutions that fit user needs and organizational goals.

  • It is easy to get sidetracked and lose focus on the actual problem, but taking a step back and reflecting helps sticking to the actual scope.

  • Constantly reminding ourselves of the problem statement is vital and writing  down can be very helpful, especially in projects that are complex.

  • Each team member brings unique perspectives, experiences, and skills, making the process efficient and effective.

  • Keeping an open mind and being willing to listen to feedback is essential in the design process.

Team members on this case: Habee Shirzad, Cecilia Parkert and Eleen Yu.

This project was one of many - make sure to check out my other projects and contact me if you have any questions about UX or my case studies.
