Common questions
What is the typical cost of design? +
It depends on the scope, but you will know before you commit: we propose a fixed fee for each work stage in writing, after the initial consultation. For a typical London extension, fees are set out as a defined percentage of build cost or a fixed sum. We will set out both options and you choose.
Is planning permission required? +
Not always. Many extensions and loft conversions fall under permitted development. Assessing this is one of the first things we do, and it is covered in the initial consultation. Where an application is needed, we prepare and submit it for you. Read the full guide.
How long does a project take? +
As a guide: design and planning typically take 3 to 5 months (councils have an 8-week statutory determination period), technical design 4 to 8 weeks, and construction from 3 months for an extension to a year or more for a new house. We will give you a written programme for your specific project.
Can drawings be commissioned without the full service? +
That is fine. Because our appointments are broken into clear stages, you can engage us for planning drawings only, or up to tender, and stop at the end of any stage without penalty.
