John Bosco Muwonge is not a man of many words. Rarely seen in public and even more rarely heard in the press, he remains one of Uganda’s most powerful yet least-known billionaires — a man whose fingerprints are all over the heart of Kampala, even if his name is often left out of the headlines.
From the crowded alleys of Kisenyi to the towering complexes of Ben Kiwanuka Street, Muwonge has quietly built an empire. He is now among the city’s top five property owners — a landlord whose arcades and shopping malls dominate the capital’s commercial pulse.
A Humble Start in Masaka
Muwonge’s story, like many from his generation, begins not with money, but with grit.
Born in Kasanje, Masaka District, he is the eldest of six siblings — including his brothers John Ssebalamu, Paul Lubega, and Haruna Ssegawa, and sisters Christine Nabukeera and the late Naiga. The family’s early life was marked by hardship. As boys, they rode bicycles loaded with bananas and coffee, ferrying goods from villages to markets in the outskirts of Masaka.
It was their sister, Christine Nabukeera — a determined businesswoman in her own right — who opened the first real door. She had moved to Kampala and later helped the brothers open a small clothing shop in Masaka in 1988. They would travel to the capital, buy second-hand clothes in bulk, and sell them in flea markets back home — braving long distances and unpredictable weather in pursuit of a better future.
They married into the same family — three brothers, three sisters — and stayed close in both business and personal life. “It was my brother John Bosco Muwonge who got me a wife, who is his wife’s sister,” recalls Ssebalamu. “It started as a joke, but it worked for us.”
The Big Move to Kampala

Those humble flea-market days taught them more than just trade. They learned mobility, negotiation, and the power of connections. Eventually, the brothers shifted base to Kampala, setting up shop near Buganda Bus Park — now Qualicel — and soon began importing clothing from the Middle East.
At the time, Kampala’s commercial core was dotted with aging, overlooked properties. While many saw decay, the Muwonge family saw potential. They bought up old structures and began to build arcades — a vision that would turn into a fortune.
Muwonge’s younger brother, Ssebalamu, is credited with building one of the city’s first arcades — Mini Price — on Ben Kiwanuka Street in the 1990s. The rest of the family followed suit.
Net Worth & Real Estate empire
Today, Muwonge’s name may not ring out in public rallies or glossy magazine covers, but his buildings speak loudly. He owns Premier Centre, Superior Complex, Kati Kati Plaza, Boost Arcade, Premium Centre, and the commercial spaces surrounding Buganda Bus Park, among others. His most recent focus has been Kisenyi, where he has transformed swampland into a bustling trade centre — building Gwanda Mall and offering rent-free months to lure new tenants.
With over 40 construction sites in Kampala and more than 400 acres in Kisenyi alone, Muwonge’s footprint is staggering. He also controls two major taxi and bus parks, including Namayiba Bus Terminal.
In 2023, some local media even listed him as Uganda’s wealthiest man — placing him ahead of long-time tycoon Sudhir Ruparelia — with an estimated net worth of $1.8 billion, almost entirely drawn from property.

Family at the Core
Throughout it all, the family has remained tightly knit.
His sister Christine Nabukeera owns several arcades, including Kisekka Auto Centre, Victor Plaza, and Nana Arcade. Lubega and Ssegawa have buildings across Kisenyi and Kafumbe-Mukasa Road, while the next generation, including Hamis Kiggundu and Haruna Ssentongo, are also making waves in the property world.
When Ssebalamu celebrated his wedding anniversary in 2018, Muwonge and his other siblings were by his side. The closeness, they say, is part of the reason they’ve succeeded. “They looked at marriage differently,” said the late Bishop John Baptist Kaggwa. “Their marriage is about friendship.”
Land, Power, and Controversy
But Muwonge’s empire has not been without friction.
He has faced several high-profile land disputes — including a long-running case involving Kafumbe Mukasa Road, where veterans accused him of grabbing 1.2 acres of land gifted to them by the President. A High Court ruling ordered Muwonge to pay Shs800 million in compensation. He never did.
In another incident, Muwonge was arrested after the controversial demolition of Nabagereka Primary School on Christmas Day in 2015. He was later released after it emerged that government officials had been complicit in the land deal.
More recently, the Ministry of Finance was urged to halt a Shs370 billion land acquisition in Kisenyi, after a woman (Eseza Nola Nakibuuka) claimed that her family held the original title to the property — now in the hands of Muwonge’s Boost Investments Ltd.
Tenant relationships haven’t always been smooth either. A rent dispute in one of his arcades ended in a shooting incident, and his rent hikes — especially during tough economic periods — have drawn protest. Still, many traders credit him for his willingness to negotiate and for stabilising rent in areas like Kisenyi.
Legacy in the Making
Whether loved or criticised, Muwonge remains a man who has shaped modern Kampala more than most politicians or planners. He has stayed out of the public eye, rarely seen at high-society events or on television, preferring instead to let his buildings — and balance sheets — speak for themselves.
He is not one to boast, donate publicly, or seek validation. But even in his silence, one thing is clear: John Bosco Muwonge has changed the face of Kampala — brick by brick.
