Designing a simple two-storey house on a low budget can be challenging, but it is possible with the right approach. One way to achieve this is to opt for a minimalist design with clean lines and basic materials. This can reduce costs while still creating a modern and stylish look. Another strategy is to focus on functionality rather than luxury, with practical features such as open-plan living areas and efficient use of space. Using prefabricated materials can also save money, as they can be assembled quickly and require less labour. Finally, choosing a smaller block of land can reduce costs and make it easier to build a two-storey home on a low budget. With the right planning and design, it is possible to create a beautiful and functional two-storey home on a budget.
