The one thing that stood out for me was the quoting. Like most people I assumed that it was going to be more and added 20% when I was budgeting. But Opun charged exactly what they quoted.

An Opun extension means…

Extending your home is an exciting project. More space for you and your family to enjoy in your home, bringing more from the outside inside! Every extension project is unique so we approach each one by understanding your key requirements and the home’s limitations, to maximise the space we can unlock. together.

The Opun process is simple and straightforward. After getting in touch with us, we’ll send out one of our surveyors to meet you at your home. They will do an initial survey and a consultation with you to learn more about your project. A clear price guide is produced a couple of days later. Then our architectural team is ready to produce a full set of structural drawings for your extension. If needed, we’ll will handle the application for planning permission on your behalf.

Opun’s team of fully vetted trade partners will carry out the work on time and on budget. Your dedicated Opun assistant will coordinate the entire project for you, and an Opun regional manager will oversee each phase of the work. At each stage, the work is signed off after a survey with yourself.

When your extension is complete, not only will you benefit from all that extra space and a boost in the value of your property, you’ll also receive an industry-leading warranty on all our work.
