I am due to start a garage conversion partitioning of half of my detached garage into an office, the other half will be left as is and used for storage. Where is the best place to buy insulation, plasterboard, plywood/chipboard and timber for making frames/stud walls? I have looked at B&Q but would imagine prices to be cheaper else where. I have limited experience of buying building materials and as the new "room" is going to be about 4m x 4.5m i will need quite a few items. Do Travis Perkins etc. sell to the public and in your experience are local builders merchants generally cheaper, are there any other places to consider? I based on the Wirral in the N/West so if anyone is local maybe they can recommend somewhere.
Sorry for the simple questions but i thought you guys would be the most experienced to ask!
Thanks Tom
