Seddon Construction is to start work on a new £5.1m care home in Banks, near Southport, for Cinnamon Care Capital.
Once completed, the home will be operated by care home provider Barchester Healthcare.
The two storey, 39,000 sq ft development was designed by Condy Lofthouse Architects and is due for completion in August next year.
John Gilman, national pre-construction manager for care sector projects for Seddon, said: "We're delighted to be using our expertise in creating high-quality, modern care homes to build this brand new facility.
"By working with our clients from the outset we ensure the design and specification meet all their requirements; the experience of our team ensures we deliver construction quality of the highest standard."
The contract was negotiated by Seddon, who identified the site and obtained planning permission.
This is Seddon's second development for Barchester and follows the successful development of a 50-bed care home known as Cheshire Grange, in Lymm, Cheshire.
