✨ Small changes make a big difference.

Thoughtful internal refurbishments have given this home a luxurious new lease of life — elevating the space with refined finishes, considered details and a timeless sense of style.

Sometimes, it’s the smallest details that create the biggest transformation.

Embarking on our latest project over in Twickenham.

Preparation is key to keeping a project clean, organised and stress-free.

Where hiring multiple skips isn’t the most cost effective solution, we offer our clients an alternative by fully protecting the front garden and access routes, allowing waste to be collected using a more economical rubbish removal service.

Internal openings are sealed off to minimise dust and noise throughout the home, while creating a temporary kitchen so the client can continue living comfortably during the build before we dismantle the existing one.

It’s these small details and forward planning that help keep projects running smoothly from day one.

Follow along to see this extension take shape over the coming weeks. 👷‍♂️🏡

We’re always incredibly grateful for feedback like this from Jessica Avery, who trusted our team to deliver her home renovation from start to finish.

From the first conversation to the final finish, our goal is always the same — exceptional craftsmanship, clear communication, and a home our clients love.

Thank you, Jessica, for trusting Cornerstone Build by Design.
