Renovations & Additions

When you love your neighbourhood but have outgrown your house, it’s time to consider a renovation or addition. The design and build team at Andy Jonkman Construction are experts at finding creative solutions to update or expand a home that no longer suits your lifestyle or personal taste.

Whether you are looking for a whole house renovation, aesthetic makeover, a reallocation of space, or need to create room to grown, our integrated design and build services and experienced construction team will turn your vision into a beautiful and functional reality.

Garages & Shops

The addition of a garage or shop can be an economical alternative to moving into a new, larger property. If you need space to store the family car and other toys, or are looking for a dedicated workshop, we can design and build a garage or shop that works seamlessly with your existing home.


As a full-service design and build company, Andy Jonkman Construction ensures that the building, renovating, or expansion of your commercial space is a smooth process from start to finish. Whether it is a pre-engineered building, warehouse, offices, or mercantile, our team of professionals can help get the job done.


Andy Jonkman Construction is located in a rural area with family in the dairy and chicken business. We can design and build a wide range of agricultural projects, and we’ll work with you to ensure your building meets the style and requirements of your operation.


Andy Jonkman Construction takes a collaborative approach to design – from concept through completion.

That means we can work with your existing architect, or you can take advantage of our in-house design services. We also complete structural engineering in-house to ensure each project is built to last. And we use Revit with 3D renderings, so you can envision every detail before it takes shape.

Our skilled design team remains by your side as you make decisions about everything from floor finishes and fireplaces to stairs and alcoves so you can create a custom space that meets your lifestyle or business requirements, reflects your personal taste, and respects your budget.
