Bruntwood has completed two small office lettings at St Hugh's in Bootle.
National security and monitoring specialist Securitas has chosen St Hugh's as the location of its new North West headquarters and has agreed a deal for 2,500 sq ft of space after relocating from Brunswick Business Park.
Willow Solutions NW, which provides outsourced contact centre services, took more 1,700 sq ft.
The 45,000 sq ft Stanley Road site was formerly home to the Health & Safety Executive before being acquired by Bruntwood. St Hugh's underwent a £3.6m redevelopment by Bruntwood.
Matt Lee, sales surveyor at Bruntwood, said: "The past 12 months at St Hugh's have been incredibly successful despite fairly challenging conditions elsewhere.
"Customers have responded very positively to our flexible terms and innovative small suite scheme, which effectively allows them to choose the exact amount of space they require, rather than making their needs fit to a pre-designated space.
"Bootle is gaining a reputation as a dynamic and up-and-coming place to do business and St Hugh's rightly stands out as one of the most attractive properties in the area. We have several other exciting deals in the pipeline and we are looking forward to another strong year as we head towards full occupancy."
Since being bought by Bruntwood in 2006, St Hugh's House has been transformed with new external paving, street furniture and planted trees, as well as revamped reception area.
