We’re creative urbanists
with a focus on participation, inclusion, and human infrastructure for happier, healthier lives.

If you want to create socially connected, delightful places and include a wider variety of people in how you plan, design and manage public space, networks and programs, we’d like to work with you.

We can help you experiment with new ways to hear from many different kinds of people. When needed, we focus on raising the voices of girls and women* especially, because we know that involving them makes places better for everyone.

Our services are novel, customisable and zeitgeisty. If you're looking for fresh ideas to get things moving, let’s connect!

About Us

Let's Connect

Hey!

I’m Karen Lee.
I founded Solidaria Studio to offer creative participation processes and measurement methods that bring more diverse people into shaping lovable, equitable places and mobility networks.

I’m a planner, sociologist and cargo-bike eccentric with specialist expertise in creating community participation processes, designing systems to support active transport, and measuring human experience of public space.
I love to immerse myself in my clients’ worlds to help them build their strategies, capabilities and public programs, evaluate their progress, celebrate their success stories, and connect a wider variety of people to richer community creation processes that make better places.
I combine a cross-disciplinary approach with my particular socio-spatial awareness, a profound justice sensitivity and a big appetite for change to gather new data and voices and help people make their places and programs more welcoming, convivial and delightful for everyone.
In addition to specialist training in Planning Cycling Cities (University of Amsterdam); Measuring Public Life (Gehl Institute); the Healthy Streets Framework (UK); Community Engagement and Deliberative Democracy (IAP2), I have a Bachelor of Arts in Community Development and Sustainable Development (Murdoch University, 2018) and a Master of Urban and Regional Planning (UWA, 2024). My affiliations include IAP2, TPA, PIA, PLAWA, Healthy Streets (Designer), Global Walkability Correspondents Network, Active Transport Forum Australia and New Zealand and the Parlour Collective.
Before becoming a full-on urban nerd, I worked in creative industry development and funding, ran a community radio station, and created large-scale arts experiences to bring people together.

Her skills include traffic and transportation planning, provision of Gateway review services, road safety auditing, traffic modelling using SIDRA software and Paramics software for macro, meso and micro modelling, car park design, concept design drafting using AutoCAD and graphic design skills using MS Office and Adobe Package programmes.

Marina was a founding Director of KCTT, now part of Premise Group Services.

She has either completed the modelling and reporting or supervised the project delivery on over 700 traffic and transport engineering studies. Being a qualified Architectural Engineer and Urban Designer, Marina’s perspective and understanding of traffic and transportation issues are unique.
Her key strengths are that she understands how great urban locations function, and she has coupled her understanding of urban planning with her knowledge of the mathematical principles and power of modelling. This provides her with superior capabilities in integrating the intended human behaviour of proposed land uses to produce best practice planning outcomes. Marina is an excellent facilitator and negotiator, with diversified business and civic experience as Chair of the NGO group The Bend in The Road in Perth which advocates for redevelopment in the City of Stirling and enhancement of public spaces on the Scarborough Beach Road corridor.

She is a certified Road Safety Auditor – MRWA & IPWEA (Registered in WA, NSW, QLD), a Gateway Team Member – BLTI (Registered Member in WA, NSW, QLD, VIC, NT), a Healthy Streets Design Practitioner and is Movement and Place (NSW) qualified.

Urban Experience Experts
Wherever possible, we use co-design methodologies that put young people’s experiences and knowledge at the centre of public realm research and design.

This approach enhances their capacity to understand how their right to the city is shaped by planning processes and builds their capabilities so they can influence they places they live for the better.
For our clients, our young consultant team provide design insights that allow us, together, to reach young people with authentic invitations to contribute and share their perspectives and ideas for future places that meet their needs.

Our small team of emerging young consultants who have completed a BIKE-CURIOUS program cycle are engaged and supported to participate and contribute throughout suitable projects.

Our principles

Imagine a bright future
Build trust across divides
Affirm individual and collective potential
Illuminate the way
Raise others up
Delight in discoveries along the way as well as destinations

*When we say girls and women, we mean to be as inclusive as possible, extending space for the particular and generalised experiences of trans and intersex girls and women, and including a respectful welcome to gender diverse people who are comfortable in spaces where the experiences of girls and women are centred. We acknowledge and seek to better understand the intersectional factors and circumstances affecting women of colour, First Nations women, women from culturally and linguistically diverse backgrounds, LGBTIQA+ people, neurodivergent women, women who are parents, and women disabled by barriers in society and city space.
