Home Extensions in Cawdor

Home Extensions done properly

ORT Construction Group builds home extensions in Cawdor where the existing house needs more usable space rather than a full rebuild. That covers ground floor extensions, additional living areas, extra bedrooms, kitchen and rear extensions, and the structural alterations that tie new work back into what is already there.

Because extensions expose existing structure, surprises happen. On Cawdor projects we plan the sequence early, open up carefully, and tell you what we have found before it turns into a cost surprise.

Questions

Home Extensions in Cawdor, answered

Do you do extensions and the internal renovation together?

Yes. Many Cawdor projects combine an extension with renovating the existing rooms so the finished home reads as one space rather than old and new.

Can you extend to create indoor outdoor living?

Yes. Wide openings, covered alfresco areas and level transitions between inside and out are common parts of the extensions we build.

How long does a home extension take?

It depends on size and structure. A modest ground floor extension is typically a matter of months on site; we give an indicative program with the quote and update it as the build progresses.

What does an extension quote include?

A written scope for the Cawdor works, the structural and framing components, allowances where selections are not final, and clear exclusions so you can compare fairly.
