How long does a house extension take?

Interior Design
This stage includes selecting the finishes and fittings of the spaces, bespoke joinery items. We use CGI visualisation techniques to produce photorealistic images of the spaces. This minimises any miscommunication between Architect and homeowner to allow you to “sign-off” on design choices. To streamline to process, this can be started during the planning determination period, however if there any changes due to planning, some work may need to be amended. We will try to minimise risk by concentrating in interior rooms which are low risk first. However, working in parallel whilst the planning applications are within determination period is at the client’s discretion.

After a successful planning application, we can then move onto the tender documents which includes building regulations and structural engineering, specialist suppliers, bespoke joinery. If your project impacts a shared boundary, a Party Wall Agreement is required. The process’s smoothness largely depends on your neighbours’ responsiveness.
