FAQs
To the right, we have addressed the most common questions regarding our luxury extension process. If you require further technical details, our team is always ready to provide the honest answers you deserve.
Do I need to move out during my home extension project?
It depends on the type of project and how much of your home is being affected. Some extensions can be managed while you remain living in the property, while others are more practical if you move out for part of the build. We will always give you an honest view based on the works involved.
How do you ensure the new extension matches my existing home?
We take time to understand the character of your home and the details that give it its identity. By considering materials, proportions, and the way old and new spaces meet, we help ensure the extension feels balanced, cohesive, and thoughtfully resolved.
Will you handle the planning permission and building regulations?
Yes, we will happily help you with acquiring planning permission and building regs upon request. We’ll explain the sequence and the timelines for submitting planning so it feels clear, organised and properly handled.
What happens if the project encounters an unexpected structural issue?
If something unexpected is uncovered, we deal with it calmly and properly. We will explain the issue clearly, talk you through the available options, and involve the appropriate structural professional where needed before any decision is made. The priority is always to resolve matters safely, correctly, and with as little disruption to the wider project as possible.
Is the structural work covered by a long-term guarantee?
Our work is supported by a written warranty on materials and workmanship, and we will always be clear about any longer-term guarantees attached to structural components or specialist systems. Clarity matters, especially when it comes to what sits behind the finished work.
