1. Budgeting
You can begin budgeting for your total extension cost now. By doing so, you can easily track your spending progress and keep control of your budget as your project moves forward. Our cost planning tool helps you avoid unexpected expenses and plan head.
2. Select Specifications
Your drawings detail the shell of your extension. What goes into the space you’re creating such as the type of flooring, lighting, heating etc. are referred to as your “Specifications”. These details are important as it gives your builders the full scope of work involved so that they can provide you with an accurate quote. Selecting your Specifications with BuildBuddy is an easy-to-follow step-by-step process. Guidance is provided along the way to help you make more informed decisions. Once you’re done you will have a detailed scope of work to share with builders.
3. Builder Quotes
Once your specifications are complete, you're ready to request quotes from builders. Providing a comprehensive project breakdown removes the guesswork and enables your builder to provide a precise quote. This clarity makes comparisons between quotes much easier and eliminates unforeseen costs. Builders love this about BuildBuddy—it simplifies communication and ensures they're fully aligned with your vision.
4. Product Selection
Once you know what is going to be included within the scope of your extension then it’s time to start the product selection process. A typical single-storey extension will require you to purchase between 50-100 different products, from light fittings to kitchen appliances, flooring and much more. BuildBuddy turns this complex task into a seamless process, helping you find products that fit your specifications and budget.
