Custom House Belfast

The beginning

Queen’s University Belfast, Linenhall Library, Belfast Castle, Botanic Gardens, and many more. It’s fair to say that architect Sir Charles Lanyon left his mark in Northern Ireland, designing some of the country’s most iconic and historic buildings.

One of his most impressive creations – the Grade B+ listed building Custom House, built in the 1850s, stands proudly in the heart of Belfast today. Over the years, Custom House has been home to various government departments, including most recently HMRC.

Recognising the untapped potential of Custom House, Northern Ireland native Neil McKibbin from Straidorn Properties purchased the building in 2021 to provide ambitious companies with unique office space.

With a profound understanding of the building’s historic and strategic importance, Neil embarked on a £14m refurbishment and modernisation programme.

Since then, it has transformed.

The present

Despite facing challenges such as Brexit, Covid-19, and other major global events – Custom House stands resilient and is now sending out a clear message: Belfast is very much open for business.

Boasting a massive floor space of 58,000 sq. ft over four levels, Custom House is at the heart of business in Belfast and invites you to be a part of its narrative.
