The block contains eight new classrooms, a sports hall, changing rooms and an office.

Speaking at the event, Mr Walker said: “Lochinver is delighted to open this newly-extended, developed and equipped building.

“The project provides our 350 boys with a bright, modern and fully resourced addition within the school’s 8.5 acre learning environment.”

The building’s layout provides computer work stations along upper and lower walkways, with new ICT and religious study classrooms.

New changing facilities, with underfloor heating, have been added next to the sports hall.

The whole block is climate controlled with motion sensor lighting and reached through a smart glass atrium, inscribed with the Lochinver crest and school motto Perstare Praestare – ‘to persevere is to succeed’.

Mr Walker added: “This enhancement to Lochinver’s educational provision marks a huge team effort, fulfilling an idea born in 2005.

“It also marks the retirement of Mrs Janet Butler, who has given 10 years’ superb service to the school and has been so key to the project’s success.”
