HOME ADDITIONS · DURHAM REGION

Home additions across Durham Region

Moving within Durham means land transfer tax, realtor fees and often a longer commute or a new school. An addition keeps your street, your neighbours and your mature trees, and gives the house the space it is missing: a bigger kitchen, a main-floor bedroom, a family room or a suite for a parent.

The hard part of an addition is not the new room. It is the join: the foundation beside an old one, the new roof meeting the old roof, matching brick or siding, and heating and electrical that can carry the extra load. We plan those details before anything is priced.

Approvals for an addition in Durham

Each municipality issues its own building permits and applies its own zoning by-law: the City of Oshawa, the Town of Whitby, the City of Pickering, the Municipality of Clarington and the Townships of Scugog, Uxbridge and Brock. If an addition goes past a setback, it may need a minor variance from the local Committee of Adjustment. Lots near creeks can also need a permit from CLOCA, the TRCA or Lake Simcoe Region Conservation.

The quality of workmanship exceeded our expectations, with meticulous craftsmanship evident in every facet of the build. The final result is a stunning cottage that not only meets but surpasses our vision.

We highly recommend Henley Contracting to anyone seeking a trustworthy and skilled contractor for custom home or cottage construction. Their dedication to excellence and customer satisfaction is truly commendable.

Ps. Thanks for the invite to your cottage this summer! Looking forward to it!

My project started before the pandemic. Work was about 30% complete and going well. The pandemic hit me a bit financially which stressed me out about the project. The Henley team helped reverse engineer and descope some of the project to suit my new affordability. They handled this with class and professionalism which im sure created extra work for them. Communication was excellent and finished product is fantastic. I will never work with or recommend another contractor again

QUESTIONSDURHAM REGION, ON

Frequently asked questions

Can't find your answer? Tell us about your project and ask us directly.

Do I need a permit for a home addition in Durham Region?

Yes. Every addition needs a building permit from your local municipality, such as the City of Oshawa or the Township of Uxbridge. Some also need a minor variance or a conservation authority permit.

Is an addition cheaper than moving?

Often, once you count land transfer tax, realtor fees and moving costs. It depends on the size of the addition and the work needed to tie it in, so we price it properly before you decide.

Can you match the brick or siding on my house?

We try to. Some older brick is no longer made, so we may suggest a close match, reclaimed brick or a deliberate contrast that looks intentional.
