WHENEVER there is a major university construction project the brush strokes of Weimin He are never far behind to carefully outline the builders' progress.

The Chinese artist who lives in Oxford, used his skills to record the different stages of the revamp of the Ashmolean Museum before then painting the redevelopment of the Radcliffe Observatory Quarter.

Now the artist-in-residence at Oxford University's estates directorate is showing his work, which also recorded the £80m creation of the Bodleian's Weston Library, which opened to the public in March 2015.

The free exhibition of paintings, entitled Reconstruction: Watercolours of the Weston Library, has gone on show at Blackwell Hall and will run until February 12.

Dr He said: "I'm delighted that the Bodleian has agreed to run this exhibition - there wasn't space to display this work until now.

"It's a small exhibition but it's a real privilege to be able to display my work in such a fantastic exhibition space.

"I feel very lucky that I was able to record the construction of the Weston Library in this way.

"The Bodleian is a very important historic building and the Weston Library really opens it up to the public.

"There are 15 pieces original work on display and about 30 other pieces on touch screen.

"Some postcards have also been produced to accompany the display."

Dr He, originally from China, moved to Oxford in 2005 and worked as artist-in-residence at the Ashmolean Museum, documenting its £61m restoration, before moving to his current job.

In 2013 he staged an exhibition to help pay for a life-changing kidney transplant for a friend in China.

More than 30 works went on display at the Sinolink Gallery in St Clement's to raise about £12,000 for a transplant for Wu Jiangwei, 24, from Nihegou village in China’s Shaanxi Province, who had suffered kidney failure.

Visitors to the Weston Library can see Dr He's watercolours from 9am to 5pm.
