Nairobi, Kenya. Put together a list of architectural firms in Kenya and Trioscape Space Planning Ltd tends to show up fairly early on it. The firm has been running since 1994, which puts it among the longer-standing names in an industry where a lot of practices don't make it past their first decade. Longevity on its own doesn't prove much, but combined with an active project register spanning hospitals, universities, churches and private developments, it's a reasonable indicator that the firm has kept adapting rather than coasting.

Trioscape operates out of the 5th Floor, Jadala Place, on Ngong Road in Nairobi. Their work covers three main strands: architectural design and planning, project management and site supervision, and interior and environmental design. That third strand is where a lot of firms on any list of architectural firms in Kenya tend to fall short, treating interiors as someone else's job once the structure is up. Trioscape's stated approach is to design the inside and the surrounding environment as one connected exercise rather than two separate handoffs.

Their client list is broad enough that it's hard to pin the firm to a single specialism. The Archdiocese of Nairobi has commissioned several projects, including the Holy Family Basilica underground parking silo in the CBD, which is complete, along with a proposed kindergarten and an art and music centre at St Mary's School. Over in Homa Bay Town, the Archdiocese of Homabay has the Most Holy Trinity Cathedral under construction with Trioscape as architects. Tangaza University College has a library proposal currently at tender stage. Add in a private mall in Kitengela, Kajiado County, a hospital proposal in Kericho, and office premises for the Africa Alliance of YMCA on State House Crescent, and you get a fairly clear picture of a practice comfortable moving between religious, educational, healthcare, retail and commercial work.

One project that deserves a mention on its own merits is the Civil Servants Housing scheme on Park Road, where Trioscape designed 1,800 residential units. Housing at that scale isn't the same exercise as a single commercial building. It involves managing repetition without producing something soulless, controlling costs across thousands of near-identical units, and getting shared spaces right for a community rather than a single client. The firm's other large-scale work includes the Village Shrine of Mary in Subukia, a religious site designed to accommodate more than 5,000 people, which asks similarly hard questions about circulation, structure and construction management at volume.

The firm describes itself as an indigenous Kenyan practice, and on a list of architectural firms in Kenya, that distinction is worth pausing on. There's no shortage of international firms with a Nairobi presence, and some do excellent work, but there's a separate and genuine value in a practice built and trained locally, one that has spent over thirty years learning how Kenyan county approval processes move, how local supply chains behave under pressure, and how to design for Nairobi's climate rather than adapting a brief written for somewhere else entirely. That kind of accumulated, unglamorous knowledge tends not to show up in a portfolio image, but it shows up in whether a project actually gets built on schedule.

Trioscape says it has worked with more than fifteen major institutions, including hospitals and the Catholic Archdiocese of Nairobi. Its current project register is a genuine mix of stages rather than a highlight reel of finished buildings: completed works sit alongside projects under construction, others at tender or scheme design stage, and at least one, the proposed administration block for the Kenya Judicial Academy in Ngong, that reached finalist stage in a design competition. That range gives a more honest sense of how an architecture practice actually runs day to day, since not every brief makes it to a ribbon-cutting.

For anyone working through their own shortlist of architectural firms in Kenya, a few things are worth checking that don't always show up in a glossy portfolio: whether the firm manages construction supervision itself or hands that off elsewhere, since that affects who's accountable once building starts; whether they've handled projects at the scale you're planning, from a single home to a multi-unit housing scheme; and whether their prior sector experience lines up with your brief, whether that's healthcare, education, hospitality or religious architecture. Trioscape's project history touches most of those categories, which is a reasonable part of why it keeps appearing whenever the subject of established Kenyan practices comes up.

The firm can be contacted through its Ngong Road office in Nairobi, by phone on 020-2668216, or by email, and takes new enquiries for architectural design, interior design and project management work across Kenya. With thirty years of history and a client roster running from Catholic archdioceses to universities to private developers, it's a firm that tends to surface quickly once anyone starts building a serious list of architectural firms in Kenya.
