You deserve to understand what a quotation includes before construction begins. A reliable price cannot be produced from floor area alone: structure, access, ground conditions, glazing, kitchens, bathrooms, building services, finishes and the connection with the existing house can all change the cost.
Once the scope and design information are sufficiently clear, DWG prepares an itemised quotation that shows what the budget covers and where individual choices affect the total. When comparing builders or construction companies in Milton Keynes, check that VAT, professional fees, structural steel, glazing, supply items, decoration, external work and contingencies are being treated consistently.
Tell us your anticipated budget when you enquire. An open conversation early in the process helps establish whether the ambition, specification and available budget are aligned.
