G Hub Sefaköy

A Mixed-Use Hub on the E-5 in Sefaköy

G Hub is a mixed-use development by Mar Yapi rising in Sefakoy, part of Istanbul's Kucukcekmece district on the European side. Positioned directly on the E-5 highway, the scheme is designed as an always-active hub that folds a hotel, an integrated shopping mall, a hospital and nearby universities into a single address. It occupies around 17,688 m2 of land with a total construction area of roughly 79,418 m2, delivering 330 residential units alongside 93 commercial spaces arranged in six-storey blocks. The concept blends living, working, healthcare and retail so that daily needs are met without leaving the complex. Homes are offered as 1+1, 1.5+1 and 2+1 layouts, split between medical-hotel units and residential apart-hotel units, giving buyers a flexible entry point into one of the European side's most connected corridors.

Location & Connectivity

Sefakoy sits within Kucukcekmece on Istanbul's European side, wrapped around the E-5 highway that links the district westward toward the airport corridor and eastward into the historic core. The location is built for movement, with the metrobus network and the Marmaray suburban rail serving the wider Kucukcekmece area and connecting both sides of the city. G Hub places residents 50 metres from Biruni University Hospital and just steps from Istanbul Arel University, anchoring the scheme in a busy education and healthcare cluster. Kucukcekmece Lake and its regenerated shoreline lie nearby, while shopping, dining and municipal services line the surrounding avenues. This dense, service-rich setting keeps the complex active around the clock and close to everything the district has to offer.

Homes & Amenities

Residences at G Hub come as 1+1, 1.5+1 and 2+1 apartments, sized from roughly 74 to 105 m2 to suit singles, couples and small families. The mix is divided between medical-hotel units and residential apart-hotel units, a structure aimed squarely at service-driven, rental-friendly living. Contemporary layouts prioritise efficient use of space and natural light, while the wider development wraps homes around shared conveniences. Because the project integrates a hotel, an on-site shopping mall and a hospital, residents and guests find retail, dining, healthcare and services within the same footprint. The 93 commercial spaces bring shops and businesses directly into the scheme, and the six-storey blocks keep the scale human. Together the unit mix and mixed-use facilities create a self-contained environment tailored to steady, always-on demand.

Investment Potential

G Hub is positioned for investors chasing dependable, service-led rental demand rather than one-off resale gains. Its location is the core of the case: 50 metres from Biruni University Hospital, steps from Istanbul Arel University and directly on the E-5, it draws medical visitors, students and professionals who need short- and long-term accommodation. The apart-hotel and medical-hotel format supports flexible letting, while the on-site mall, hotel and hospital keep footfall high year-round. A mixed-use hub on a major European-side corridor tends to hold occupancy well.
