13 new homes are being built in Onchan.
Dandara has started the development of The Willows in Lonan.
The four-bedroom properties will be ready for occupation at the start of 2019.
Commercial Director David Thomas says: "Much of this development includes a brand-new style of split-level home which we have not built in the Island before and is only available at The Willows.
"It is an exciting development and will provide high-quality homes with coastal views in a superb location within easy reach of local amenities."
