Building understands that the deal was expected to be completed this week but will not be finalised until next week.
The deal, which will lift Rok’s turnover to about £300m and place it in the contracting top 30, is a significant step in chief executive Garvis Snook’s plan to transform Rok from a regional contractor into a national player.
Llewellyn, which operates in the South-east, is considered to be a good fit for Rok. An industry source said: “The deal will take Rok a few rungs up the ladder and get them out of the South-west. It is achieving some critical mass. It has been looking around for a while and seems to have found a target.”
A Rok spokesperson said the group never commented on market speculation. Llewellyn joint managing directors Tim Lewellyn and Judy Llewellyn-Burke both denied their firm was in talks.

Rok’s turnover last year was £125m; Llewellyn’s was £160m for the year to 30 September 2001.
Llewellyn concentrates on the retail, leisure, office, PFI and housing sectors. It also has a joinery business and a concrete repair arm.
Rok has undergone rapid changes since Snook took over in 2000. His first moves were to make 120 staff redundant and change the firm’s name from EBC.
