Guides before you build
All guides
Building Regulations for a house extension: what building control checks
Almost every extension needs Building Regulations approval, whether or not it needs planning permission. Here is what is checked and when inspections happen.
Planning a new build home: what to have in place before work starts
A new build starts long before the first day on site. Here is what normally needs to be in place: consents, drawings, utilities and the people involved.
Removing a wall: structural alterations explained
Opening up a layout often means taking out a wall. Here is how load-bearing and partition walls differ, and what approvals and design a structural change needs.
Frequently asked questions
All FAQsHow do I get a quote?
Use the quote form on our contact page or give us a call. Tell us what you would like built, the type of property and where it is. We will come back to you, arrange a site visit if one is needed and provide the quote in writing.
Can I ask for a site visit?
Yes. Choose “Request a site visit” on the contact form and tell us your preferred date. A preferred date is a request only, so we will contact you to agree a time that works for both of us.
Which areas do you cover?
We work across London. If you are unsure whether we cover your area, send us your postcode and we will let you know.
What types of building work do you do?
We carry out house extensions, loft conversions, refurbishments, new builds and commercial construction. If your project is not on that list, get in touch and we will tell you honestly whether we can help.
Do I need drawings before I contact you?
No. If you already have plans, send them and they will help us quote more accurately. If you do not, tell us what you have in mind and we will talk through the next steps.
Will I need planning permission?
It depends on the property and the work. Some extensions and loft conversions can be built under permitted development rights, but homes in conservation areas, flats and properties with removed rights usually need planning permission. Your local planning authority has the final say, and we will explain what is likely to apply.
