Sofia’s 10 Largest Building Permits in 2025: The Mega-Projects Reshaping Bulgaria’s Capital

134,000 m² New Record, 860 Apartments in Five Towers, Two 75-Metre Landmarks, a 3,000-Unit City-Within-a-City, and the Districts Driving Sofia’s Construction Boom

Introduction: A New Scale of Ambition in Sofia

Sofia’s construction sector raised its ambitions significantly in 2025. Until recently, the largest residential building permits issued in the Bulgarian capital covered approximately 100,000 m² of total floor area per project. In 2025, the largest single permit broke through that threshold to reach 134,000 m² — or more than 227,000 m² when basement and underground parking levels are included. This is the first phase of a project that, at full completion, will rank among the largest residential developments ever built in Sofia.

The 10 largest building permits issued by Sofia’s Architecture and Urban Development Department (NAG) in 2025 paint a vivid picture of where the city is growing, who is building it, and what the next wave of Sofia’s residential and mixed-use supply will look like. They also reveal the capital’s investor geography: projects are scattered across Mladost, Manastirski Livadi, Simeonovo, Karpuzitsa, Ovcha Kupel, and Mladost 3 — confirming that Sofia’s construction boom is not confined to any single corridor.

Across the Top 10 alone, these projects will collectively deliver thousands of apartments, hundreds of thousands of square metres of residential floor area, and a range of commercial, hospitality, and public amenity uses. For investors tracking Sofia’s new-build pipeline, these permits represent the committed supply that will enter the market over the 2027–2030 window — the horizon within which today’s off-plan buyers are making their decisions.

The Top 10 at a Glance

1. Rodina Residence — Tsarigradsko Shose / Mladost

Largest permit in Sofia’s recent history — 134,000 m² above ground, 227,600 m² total

The standout permit of 2025 by an exceptional margin, Rodina Residence is being developed on the former Rodina industrial complex site in the Mladost district, adjacent to the Tsarigradsko Shose boulevard. The project is 3–4 times larger than any other permit in the top 10 by above-ground floor area and represents a new milestone in residential development in Sofia.

2. SReDA — Manastirski Livadi Iztok, Triadica

40,000 m² — BLD / AG Capital’s latest phase in one of Sofia’s most sought-after residential districts

SReDA is the latest residential project in the Manastirski Livadi Iztok area by BLD, the development arm of AG Capital — one of Bulgaria’s leading real estate holding groups. The project continues BLD’s established track record in this premium southern Sofia submarket, where the group has already completed and sold four residential buildings (Mona 1–4) and currently has two further phases under construction (Mona 5 expected Act 16 October 2027; Mona 6 by March 2029).

3. Sky Towers AMur — Manastirski Livadi

31,700 m² — Two 75-metre towers, 265 apartments, infinity rooftop pools, priced €243,000–1.8M

Sky Towers AMur represents the premium end of Sofia’s 2025 residential pipeline. Described by its developers as a future architectural landmark of the city, the project consists of two 75-metre glass-facade towers in the Manastirski Livadi district, with panoramic views of Sofia and Mount Vitosha in all directions.

4. Paramont Gardens — Karpuzitsa, Vitosha Area

29,600 m² — Six buildings in three phases; Israeli-led investor group

Paramont Gardens is a six-building residential complex in the Karpuzitsa area of the Vitosha administrative region, positioned near Tsar Boris III Boulevard and the Vladaiska River. The project is structured in three phases over five years, with the first four buildings already listed for sale.

5. Capitol Residence (Phase 2.1) — Serdika, Zadgarova Arteria

26,500 m² new phase — part of a 108,000 m² mega-complex with 3,000 planned apartments

Capitol Residence is one of Sofia’s most ambitious urban development projects in terms of sheer apartment count: 3,000 units planned across 108,000 m² of total built area on a 22.7-decare site behind Central Railway Station in the Serdika district. The 2025 permit represents a new phase of a project that has been under construction since 2021.

6. Cherry Garden — Lvov Tolstoi / Nadezhda Park

26,300 m² — 300 apartments; Bravo Development; metro access

Cherry Garden is a residential project by Bravo Development in the Lvov Tolstoi neighbourhood, positioned near Nadezhda Park and the Khan Kubrat metro station. The project offers 300 apartments across two-, three-, and four-room configurations with both underground and above-ground parking.

7. Eria (Emblema Zone 1) — Ovcha Kupel

22,500 m² — 208 apartments in two 16-floor towers; pharmacy, grocery, café

Eria is the latest development phase from the Emblema project group in the Ovcha Kupel district, where the same developer has previously completed Alera 1 (sold out), Alera 2 (near completion), and the Aritsa building in Manastirski Livadi. Eria is conceived as a more ambitious, larger-scale project building on the same developer’s district track record.

8. River Park Phase 2 (Alleys 6–7) — Simeonovo, Vitosha Foothills

88 houses / 21,000 m² — 350+ total homes; international investor; 75% green space

River Park is one of Sofia’s most distinctive residential projects: a low-density development of individual houses at the foot of Vitosha mountain in Simeonovo, conceived around an unusually generous 75% green space allocation. The project began with Phase 1 (110 completed and occupied houses) and is now well into Phase 2, which adds a further 240+ houses across seven alleys.

9. Eternal 4 — Malinova Dolina / Studentski

19,600 m² — 8 buildings, 356 apartments; 4th project from same developer in same area

Eternal 4 is the fourth residential project delivered by Softbultrade in the Malinova Dolina area — the Studentski district corridor near Sofia Ring Mall. The sequential development of the same submarket reflects the developer’s established understanding of demand in this zone, which combines student and young-professional rental demand with ring-road access.

10. Synerga Premium (Building B) — Mladost 3

18,000 m² new phase — 120 apartments; all south-facing with Vitosha views

Synerga Premium Complex in Mladost 3 is a high-specification gated residential complex developed on part of the site originally planned for the Grand Canyon mixed-use project — a long-delayed development of which only a park, an administrative building, and a foundation pit had been completed. The 2025 permit for Building B follows the 2024 permit for Building A, taking the total complex to approximately 32,300 m² above ground.

Guide for Foreign Investors: Buying Into the Sofia New-Build Pipeline

What to Check Before Committing to Off-Plan in a Mega-Project

For foreign investors considering purchasing off-plan in any of the Sofia mega-projects described in this article, the scale of the development creates both opportunity (potentially lower entry prices in early phases) and risk (longer completion horizons, more complex developer structures, greater concentration of counterparty risk). The standard due diligence framework applies with additional emphasis on developer-specific checks for large projects.
