Not sure where to start with designing your new home? Follow architect Opinder Liddar's guide to the four stages of house design. If you’re a first time self builder it’s hard to know how to start planning your design. To make the process simpler, you can categorise it into four stages. Factors from each stage must be evaluated, explored and assimilated into the design of your proposed building. Building your new home is exciting, especially when you understand how the process works. Keep in mind that the homebuilding process may vary from region to region and builder to builder, especially if you’re building an elaborate custom home. Be sure to ask your builder about his or her specific policies and procedures.
