LONDON, Dec 11 (Reuters) - Blackstone has pulled

out of talks to buy a landmark office property in the City of

London after its owner Nuveen refused an offer of around 300

million pounds ($382 million), two sources familiar with the

matter told Reuters.

A deal at that level would have represented one of the

largest transactions in European real estate this year, but the

two parties failed to agree on a price for the building at 70 St

Mary's Axe, locally known as the 'Can of Ham'.

The 516,000 square foot property, which is let to a range of

tenants including law firm Sidley and energy firm Vattenfall,

remains on the market, one of the sources said.

News of Blackstone's unsuccessful offer was first reported

by Green Street News.

Real estate markets globally have struggled to shake off a

post-pandemic malaise of declining occupancy and market values,

complicating some transactions and leaving lenders fearful for

the security of debt lent against some non-prime assets.

The 'Can of Ham' is one of several big-ticket office

properties in Britain on sale that are being watched closely as

a test for whether buyers and sellers can agree on price, or

whether the drought in deal volumes continues.

Analysts at Jefferies on Tuesday said office markets in

London, Paris and New York faced "new realities", with increased

demand for more flexible, attractive office space to woo staff

reluctant to ditch remote working.

Citing a study by global property services firm Cushman &

Wakefield ( CWK ), the Jefferies note said that 86% of employees want to

work at least 3 days a week in the office in France, compared to

83% in the UK and 57% in the United States.
