A website redesign to renew an architecture studio

Lara Castillo Studio


An architecture studio needs an online presence as refined as its own projects. In this UX/UI case study, I worked on redefining the digital identity of Lara Castillo Studio, focusing on intuitive navigation, minimalist visual design, and mobile optimization.

The goal was to create a website that reflected the brand’s elegance, made it easy to explore projects, and improved communication with potential clients.

Problem

The website of Lara Castillo architecture studio did not adequately reflect its modern and professional image. It had navigation issues—especially on mobile devices—lacked updated and relevant content, and didn’t offer an intuitive user experience. This negatively affected the brand’s perception and made it harder for users to explore the studio’s projects.

Solution

A minimalist and optimized website was designed and developed, focusing on showcasing architectural projects through a smooth user experience. The design prioritized mobile navigation, included advanced filters to help users find projects easily, and enhanced visual presentation. Accessible elements were also incorporated, such as alternative text and improved color contrast, to ensure an inclusive experience.

Role

UX/UI Designer

Duration

The project spanned approximately 12 weeks, divided into the following phases: research and definition (4 weeks), ideation and prototyping (6 weeks), and testing and final adjustments (2 weeks).

Key Points

Throughout the ideation sessions, the team worked with a focused approach to address the three main pain points identified during research: lack of responsiveness, insufficient content, and navigation issues. Each technique applied was oriented toward generating clear solutions aligned with user needs.

Lack of responsiveness across devices
  • We started with the basics: simplified menus for small screens, use of scalable images, and fluid layout design.
  • A key idea was to implement breakpoints to ensure optimal display on mobile devices and tablets.
  • A "mobile-first" approach was adopted for critical elements like navigation and visual content presentation.

Outdated and uninformative content
  • We identified the need to include detailed technical specifications, high-quality image galleries, and comprehensive project descriptions.
  • We benchmarked best practices for content presentation in the architectural industry.
  • We concluded that each project should follow a standard structure including image galleries, detailed descriptions, technical data, and related links.

Navigation issues
  • Efforts focused on designing a logical, easy-to-use navigation system across all platforms.
  • Ideas included organizing user flows based on interests and user behavior.
  • We proposed features like accessible menus, breadcrumb trails, and simplified navigation options.

Design

We entered the design stage by creating the sitemap—a key step for structuring content in a logical, user-centered way. The main insights gathered during the ideation sessions laid a solid foundation for sketches and prototypes, ensuring the final design addressed the identified issues and met the client’s expectations.

Paper Wireframes

The next step was to sketch the wireframes. I focused particularly on the pain points identified earlier. I chose a minimalist, modern, and elegant design where visuals take center stage, and layout elements are arranged in a simple, clean, and effective way. The layout’s classic structure was intentionally kept sober, allowing the studio’s architectural innovation to stand out and be appreciated in full.


Infographic about 'Paper Wireframes'. It shows five sketches: four are hand-drawn layouts with marked sections, and one interface combines the selected elements.


Although the main goal was to develop a fully responsive website, I chose not to apply a strict mobile-first approach. The reason lies in the nature of the content: the studio’s architectural projects require a wide visual space to be fully appreciated.

Since these works are the core of the site, I decided to prioritize their presentation on larger screens, ensuring an immersive and high-impact visual experience.

Later, I adapted the design for mobile environments, where we had identified more navigation challenges among our target users. This strategy allowed us to maintain both visual and functional integrity across all platforms, delivering a consistent and satisfying experience on any device.

Prototyping

Low-Fidelity Prototype

We started by creating simple wireframes that translated the ideas and conclusions from the ideation phase into an initial visual structure. This step allowed us to quickly validate content organization, prioritize key elements like mobile navigation and project cards, and make early adjustments based on team feedback. The focus was on ensuring a clear and functional experience that would serve as a foundation for more detailed iterations in the next phases.

Usability Study

The next step was to conduct a usability study to identify potential navigation and functionality issues in the low-fidelity prototype before moving forward with more detailed versions. This step is crucial to validate that early design decisions effectively respond to user needs, allowing quick adjustments to flows, interactions, and content hierarchies. The goal of conducting these tests at this stage is to ensure that the final experience is intuitive, efficient, and aligned with the project’s objectives.
