Expand your space without compromising what makes your home yours.
Your home has served you well — and sometimes that means it’s time to ask more of it. At de Blois Built, we build custom home additions that feel like they were always part of the plan. Not tacked on. Not visually disconnected. Properly integrated — structurally, aesthetically, and functionally — with the home you already have. Additions require careful planning to ensure structural integrity. We work with engineers and designers to create plans that are safe, functional, and visually cohesive.
We manage the entire process from feasibility through final walkthrough, coordinating design, permits, and trades under one roof. Serving Northumberland County, as well as Prince Edward County, Hastings County, Bay of Quinte, Peterborough and the Kawarthas, we bring the same standard of care to an additional project as we do to a full custom build.
A well-executed addition requires more than skilled labour — it requires careful planning, clear and accurate scope definition, expert cost consulting, and a contractor who understands how best to integrate new construction with existing structures. Defining the scope of work for an addition can be more complex than a new build; the builder you choose can determine whether the process feels controlled or chaotic. Here’s how we approach each project:
Every addition is different and additions demand careful planning to ensure structural integrity and flow. We can help guide you to the best type of addition for your home and your needs, whether it’s a rear addition, a second storey addition or a site expansion. Below are the types of projects we regularly take on across Northumberland County and surrounding areas — each managed with the same full-scope process.
When your property needs more functional space, we build garage and storage additions that complement your home’s existing footprint and exterior character. From attached single-car garages to larger detached structures with storage above, we design for utility without sacrificing how the property looks from the road.
