From Tobacco Factory to a 356-Unit Complex: Garden SUN Takes Shape in Mostar
The 20,000-square-metre site of the former Mostar Tobacco Factory is being transformed into Garden SUN, a mixed-use complex that will add 356 apartments, 12 commercial spaces and more than 460 parking spots to the city’s residential stock. Work is visibly advancing on the site in the Tekija neighbourhood, as shown by drone footage posted by Emir Spahić, the former captain of Bosnia and Herzegovina’s national football team and now a lead figure in the project.
The development is a joint venture between Spahić’s company Alarm Gross (co-owned with businessman Mirsad Ćatić) and Herc invest, a Trebinje-based firm linked to entrepreneur Bratislav Pidžula. Designed around an internal garden and split into four buildings of eight lamellae, Garden SUN offers one-, two- and three-bedroom units aimed at families, young couples and investors. The scheme replaces a long-abandoned industrial eyesore with a residential hub that is expected to reshape the appearance and housing mix of this part of Mostar.
The Business Empire Behind Spahić’s Mostar Vision
The Expanding Portfolio of a Former Athlete
Spahić and Ćatić already control the Plaza shopping centre in Mostar through Alarm Gross, and in early 2025 their company acquired an 18% stake in SEC One Sarajevo, the security firm that emerged after Sweden’s Securitas exited Bosnia. Public disclosures for 2025 show Alarm Gross generated revenue of around KM 4.66 million (approximately €2.4 million) with 11 employees—a small but profitable operation. The foray into a 356-unit residential project marks a significant leap in scale and capital commitment, diversifying from commercial real estate and security services into large-scale housing development.
Why a Mostar-Trebinje Partnership Matters
Bringing in Herc invest, a player from eastern Herzegovina, spreads risk and taps additional capital. The partnership structure also reflects the way business networks in the country often bridge different regions. Converting a former industrial site into a residential complex is a growing trend in the Balkans, where centrally located brownfield plots offer bigger land parcels at lower entry costs—though demolition and remediation expenses can be high. Garden SUN’s provision of 463 parking spaces for 356 apartments is unusually generous for the region, signalling a design aimed at car-dependent households and a bid to stand out from competing developments.
What Garden SUN Means for the Local Property Market
For those with a stake in Mostar’s property market, the project introduces a number of practical considerations:
- Potential homebuyers: With 356 new units entering a city of roughly 100,000 residents, the balance of supply and demand will be crucial. If absorption is slower than expected, asking prices could soften, especially for one- and two-bedroom flats. Keep an eye on the launch pricing—if it comes at a premium to existing stock, it may need to justify that with finish quality or amenities.
- Existing apartment owners: A large injection of new supply in a relatively small market often puts downward pressure on rents and resale values in the short term. Owners of comparable units may want to lock in long-term tenants or consider upgrades to maintain differentiation.
- Other developers in Bosnia: The Spahić-led effort shows that brownfield conversion can be viable when paired with strong local partners and a recognizable public face. But the scale requires patient capital; four buildings of eight lamellae cannot be built all at once unless pre-sales are robust. Competitors can watch how phases are released to gauge genuine demand.
Risk & Opportunity Assessment
| Commercial Risk | Medium | The 356-unit scale is large for Mostar; if sales lag, the investors face extended holding costs and potential write-downs on a project built across four buildings. |
| Competitive Risk | Medium | Other residential projects in Mostar may compete for the same pool of local and diaspora buyers, squeezing margins if Garden SUN has to discount to maintain velocity. |
| Regulatory Risk | Low | The conversion of an industrial site to residential has passed planning; no reported legal or zoning disputes at this stage. |
| Reputation Risk | Low | Emir Spahić’s status as a former national captain gives the project visibility; no negative publicity is attached, although any personal controversy could spill over. |
| Technology Disruption | Low | The development uses conventional construction methods; no novel technology risk is present. |
| Commercial Opportunity | Medium | If the housing market in Mostar remains steady, the project could generate solid returns, but the opportunity is bounded by the city’s modest population growth. |
