Adu design

Consider several factors when finalizing your accessory dwelling unit (ADU) design. By carefully considering the following design elements, an ADU can serve as a functional living space and add value to the property.

Design Layout

One of the most important considerations is maximizing functionality while maintaining aesthetic appeal. A well-planned layout is required to make the most out of compact space. Start by identifying the key living spaces that need to be included – the bedroom, bathroom, kitchen, and living area – and consider how these can be arranged to create a natural and convenient flow. Having a layout that feels open and airy is crucial, which can be achieved by using open-plan designs, ensuring each room has ample natural light. Storage space can often be overlooked in small units, but it’s vital to maintaining a clutter-free, liveable space, so consider built-in storage solutions in your design. 

As you plan to build an ADU, remember outdoor space. Adequate outdoor space adds beauty to the ADU and provides additional recreational room to the occupants. You can incorporate a patio, garden, or deck, depending on the size of your property and the design of your ADU.


Home design should incorporate functionality while also maintaining an aesthetically pleasing look. Consider the placement of furniture, appliances, and other fixtures to ensure that they are accessible yet not intrusive. There should be ample space to move around and the design should not hinder movement. ADUs should ideally have enough windows to allow for natural light and ventilation, boosting the overall ambiance of the space. Consider incorporating energy-efficient features, such as solar panels or insulation, to reduce long-term maintenance costs. When building an ADU, think about energy efficiency and sustainability. Incorporating features such as solar panels, high-efficiency appliances, and plumbing fixtures will reduce your utility bills.  

Blend Cohesively

Your ADU design should blend with your existing home’s architecture and function independently. Think about the ADU’s exterior design, how it will blend in with the surrounding landscape, and how the inside will be arranged for optimal space. The exterior design of the ADU should blend harmoniously with the main house and the surrounding environment, maintaining a cohesive look throughout the property.

By keeping these factors in mind, you can create an ADU layout that maximizes the potential of the space while ensuring a comfortable and practical living environment.
