Ellmer Construction is tipped to win the contract to build a Great Portland Estates office block in east London, as the developer targets less central parts of the capital.

The FTSE 250 developer has traditionally focused on the West End and the centre of the capital, where its projects have included Make’s Rathbone Square scheme built by Lendlease and AHMM’s 240 Blackfriars, built by Mace.

It is on site with two other schemes in the West End, a £59m deal on Oxford Street by architect Orms to revamp a 1950s building called Oxford House, where Erith has begun demolition work, while Mace has started on the £150m Hanover Square mixed-use scheme on the junction of New Bond Street and Brook Street, which incorporates the eastern entrance to the Crossrail station at New Bond Street.
