Antrim construction company Mivan has announced it has secured projects worth about £6.5m in the residential and cruise ship sectors.
One of the contracts - worth over £3m - involves demolishing a house in rural Oxfordshire and replacing it with a new five bedroom home.
Mivan will be responsible for the build, mechanical and electrical work, joinery, and interior fit-out.
Its cruise ship division has also secured two contracts in the Bahamas.
The company's director of business development, Stephen Mills, said: "We also have some repeat business with Princess Cruises, involving a major refurbishment on the Grand Princess, also in the Bahamas.
"It's a very demanding schedule, with a lot of work to be carried out in a two to three week period."
He said there was a growing market for the residential projects.
"The contracts can be worth anything from £2m for a major refurbishment, to £25m for a rebuild," Mr Mills said.
"The contract in Oxfordshire involves the demolition of an existing premises, and its replacement with a new house with a library, swimming pool, and a grass roof.
"But we think that most of this kind of work will be in London, in areas like Chelsea, Belgravia, and Knightsbridge.
"We are already tendering for a number of projects, and we hope to be making more announcements over the next few months."
