Fidelity Investment Managers has bought Brunswick Gate in Southampton for £11.2m, the biggest investment in the city centre this year.
The 50,000 sq ft building is let to Natwest for an unexpired term of six years, equalling a net initial yield of 7.8%.
The building was sold by DTZ, which acted for Aviva.
Lambert Smith Hampton acted jointly with Whitmarsh Holt Young for Fidelity.
Jerry Vigus, director of South Coast Capital Markets for Lambert Smith Hampton, said: “It has been widely reported that we are seeing an increasing shortage of grade A office space and for Fidelity to secure Brunswick Gate – the biggest office investment in Southampton city centre – is a success that they can be proud of.”
