We are well aware that there are many DIYers who, with guidance, are more than capable of executing the smaller buildings such as single and double garages or workshops, to this end our MANEX software has a specific erection/installation guide specially programmed to your exact building dimensions, which is a step by step procedure from setting out through to erection and completion of flashings, trims and doors etc. If however you are still unsure, we are only a phone call away from remedying your query.
