Planning

We've recently got planning permission for a 2 storey side extension and our builder has suggested that we can progress on a building notice to avoid more drawing costs. Can you offer advice on this?

We are looking to submit a planning application to reconfigure our ageing detached 4 bed property with the possibility of extending into the loft space and constructing a rear extension. What is the best way to start this process?

We are interested in designing and building a new replacement house on an existing plot. Is traditional masonry still the way to go or should we consider alternative construction methods?
