J & B O'Brien Builders & Contractors
Website
J & B O'Brien are building contractors based around the South Croydon area, specialising in small private build work and working for local authorities on schools. We employ direct trained labour, but also call on reliable sub-contractors for specialised work. Our direct labour team have all been CRB checked.

We are registered with the Federation of Master Builders and the Construction Industry Training Board, to whom we pay a levy annually to assist with Apprentership training. Formed in 1973 by Directors John & Beryl O'Brien, the early years consisted mainly of Housing Association refurbishment work.
Services
As a company, we specialise in providing a cost effective service for private projects. Anything from minor alterations to paths and drives, through extensions to existing property, to a completely new build. Whatever you need, J & B O'Brien is here to help.

In this case study we show the progress of a building a new property for a private client, starting with the laying of the ground floor flooring joists and following the progress as we add the rest of the ground floor, up with the first floor and and finally the roof, complete with the detailing in the dormer window.
J & B O'Brien have established a reputation for quality work for Local Authorities. This case study shows the progress of a project for a local school, where obsolete classrooms that were no longer being used were replaced with a new outdoor classroom and stage. The first stage of the project was to clear the old site and prepare it for the new construction about to take place.

Report
Having worked with many contractors in my line of work as an Architectural Director at Jameson, J&B O'Brien are one of the best local contractors from small to larger scale extensions and new builds.
Their communication, knowledge and extensive experience all contribute to a very high standard of workmanship. On the many previous and current projects my team and I have worked on with them, every single one of our clients has been extremely pleased with the result and process!
