ARU CUSTOM BUILDS

An Accessory Residential Unit (ARU) is a fully self-contained home built on the same lot as your existing property—perfect for multigenerational living, rental income, or added space.

At Modern Day Builder, we’re proud to be London’s leading choice for custom ARU builds. While many companies only offer prefabricated models with fixed layouts, we take a fully customized approach—maximizing every inch of your available square footage and tailoring the design to suit your style, budget, and unique needs.

From concept to completion, we build smarter, not smaller.

HOW WE ARE DIFFERENT

FULLY CUSTOM BUILDS

Most builders offer cookie-cutter models with fixed dimensions and layouts. We design and build your ARU from the ground up, maximizing your available lot space and tailoring every detail to your lifestyle.

END-TO-END PROJECT MANAGEMENT

From zoning checks and permits to interior finishes, we handle the entire process. You won’t need to juggle multiple contractors—we’re your one point of contact from start to finish.

LOCAL EXPERTISE IN ARU REGULATIONS

We understand London’s zoning bylaws, building codes, and permit process inside and out. Our Discovery Package ensures you get accurate, upfront answers about what’s possible on your property.

BUILT FOR REAL LIVING

Your ARU isn’t just a structure—it’s a fully functional home. We focus on comfort, design, and long-term value to create a space that doesn’t just meet requirements but truly elevates your property.
