Engineering consultancy Scott Wilson - the firm developing a new master-plan for the historic Bournville Estate in Birmingham - has floated on t he London Stock Exchange.
And its staff have already seen a bumper profit.
The Basingstoke-based company saw its shares - given a placing price of 158 pence - shoot up to 180 pence at market close, valuing the company at #128 million.
A total of 43.1 million ordinary shares placed, raised #68.1 million before expenses for the firm.
In addition, another 2.2 million ordinary shares produced #3.5 million.
The shares were bought by a wide range of institutional and professional investors, having been oversubscribed at the higher end of expectations.
Scott Wilson, which was 100 per cent owned by its 3,800 employees, aims to expand both in the UK and internationally through organic investment and acquisitions.
The proceeds from the float will also be used to repay debt and top up its pension scheme.
Scott Wilson reported adjusted EBITA (earnings before interest, tax and a m o r t i s a t i o n ) o f #7.8 million on sales of #160 million in the year to April 2005.
Late last year the company was appointed as landscape architects to prepare a new masterplan for the Bournville Estate.
Its purpose is to produce a vision for the future for the 1,000 acre estate in south Birmingham, home to more than 27,000 people.
The masterplan will explore options for the development of open spaces, woodlands, play facilities, streams and hedge-rows, including coming up with proposals for the refurbishment of The Green, at the heart of the village.
It will also aim to develop the aspirations of the Cadbury family's original objective of producing "a model of good planning, open to all", and address how the village can meet the needs of the 21st century.
Scott Wilson's Birmingham landscape and urban design team beat 15 other practices to win the commission.
Chairman Geoff French said he was delighted with the firm's admission to the stock exchange.
"We believe that the Placing and Admission will strengthen Scott Wilson's balance sheet thereby financing organic growth and facilitating further selective acquisitions," he said. "We expect it will enable the company to accelerate its growth."
Brewin Dolphin acted as the company's sponsor and financial adviser.
