Cornwallis Road Oxford

Planning a 2 storey extension? Wondering how much it will it cost? The answer depends on what else you have planned for your home. Usually the costs incurred go beyond that of building and fitting out the 2 storey extension. Remodelling of the layout, some redecoration and other updating work on the existing building often happens too, as illustrated by this project.

Cornwallis Road OxfordThe Project

Our Oxford based client had lived in their home for a while and spent some time working together with their architect to design a flowing, practical updated space. The new design for the extended and remodeled house made the layout more efficient, meaning that the client was creating a larger house whilst regaining some outside space in the garden. Alongside reconfiguring the layout with a 2 storey extension, the whole house was to be updated with a full redecoration, new wiring and plumbing, as well as new flooring, windows, kitchen and bathrooms. 

The Challenge

Our clients were a busy working couple, who had limited spare time and a set budget for the building works. They needed help to set up and organise the construction works and were keen to have an independent expert to prevent any delays or costly overspends.

The Solution

CLPM were appointed to help support our clients by delivering both construction cost advice services and project management support. We started by analysing the architectural designs and working out a line by line estimate of the costs to build the 2 storey extension, plus the additional refurbishment works. We used this estimate to create a budget for the project, and a benchmark figure for the builders’ quotations. Next we agreed the list of builders to approach and prepared the tender documents. We put the work out to tender, and managed the tender process for our clients to both main contractors and individual trades.

After analysing and talking through the tender returns with our clients, they chose to build using a single, main contractor and using CLPM for Contract Administration. This involved our project manager monitoring the progress and quality of the building works and overseeing the build to ensure everything went according to plan. Contract Administrators also monitor the cost of the project by checking and then signing off invoices and dealing with any cost variations as they happen. 

The result

The house is now a bright modern space. It project took 6 months to complete but was completed smoothly and to a high level of quality – and with the minimum stress and disruption to our clients. 

CLPM Services used by our clients:

Design Review, Budget, Tender Process, Monthly Cost Reporting. Contract Administration with site monitoring.

For me the biggest single thing was the knowledge that somebody who knew what they were doing was worrying about this project. It wasn’t just us worrying. Somebody else had the responsibility for making it happen. So the buck stopped with somebody else who knew what they were doing. I would have had sleepless night for six months. But I knew there was somebody else doing it and doing it right. That was worth paying the money for. That sheer peace of mind about the whole experience and that was worth every penny. It was attractive to us to have them managing the tender. It‘s frustrating ringing around builders… I wanted somebody who knew what they were doing. Certain things can seem insurmountable when you don’t know the right questions to ask. CLPM always knew immediately what to do when there were questions or issues…… a project manager makes all the difference. “
