Taylor Woodrow Construction has topped out the £24.5 million Post Box scheme in Birmingham city centre.

It is being built for Cala Homes (Midlands) which last year pre-sold all the apartments in one transaction to Irish residential property investment company, Earthquake, in one of the largest apartment deals concluded in Birmingham.

Built in three different blocks, comprising 258 one and two bedroom apartments, including 30 affordable units, the project is due to be completed three months ahead of schedule at the end of March, 2006.

Situated in Commercial Street, adjacent to the Mail Box, the Post Box stands on a brownfield site, originally occupied by light industrial premises, and boasts an internal courtyard and underground parking.

It incorporates a concrete frame with the three buildings varying up to four, five and six floors, with roof patios to some penthouse units.

The apartments, priced between £ 160,000 and £ 240,000, vary in size between 400 sq ft and 1,200 sq ft.

Matthew Antill, Cala Homes (Midlands) commercial director, based in the company's Sheldon offices, said: "After our successes at QUBE and Broadway Plaza, Post Box is yet a further example of Cala's award- winning design and style."

Cala Homes (Midlands) said it would announce plans for further Birmingham city centre developments in the next three months.
