What happens while it is decided
The process from here
This application is with Richmond upon Thames for determination. The council publicises it, consults neighbours and technical bodies where required, and weighs the responses against local and national planning policy.
The statutory target is eight weeks for most applications and thirteen for major development, though extensions of time are common. Comments carry most weight while the case is undecided, so check the council portal for the deadline if you want to respond.
About prior approval applications
How this application type works
Prior approval applications arise where permitted development rights already grant the principle of the work, such as larger home extensions, changes of use to housing or agricultural buildings. The council may only consider the specific matters set out in the rules, for example transport, flooding or appearance, and in many classes the work may proceed if the council does not respond within the deadline, commonly 56 days.

10, Ellerman Avenue, Twickenham, TW2 6AS
Non material amendment to planning reference PA26/0815 to allow for proposed amendments to the approved rear extension at the above property. Bifold Door — Ground Floor Rear Elevation It is proposed to increase the width of the approved bifold door unit at ground floor level of the rear extension by 1 metre. The revised door will retain the same design, materials, and glazing specification as approved. The amendment improves access and connectivity between the internal living accommodation and the rear garden, consistent with the design intent of the approved scheme. Rear Extension Roof — Revised from Part Flat/Pitched to Fully Flat. It is proposed to amend the roof form of the rear extension from the approved part flat and part pitched arrangement to a fully flat roof. The existing approved pyramid rooflight will be retained in its current position, maintaining the architectural feature and natural light provision established by the original permission. The revised flat roof form is considered to result in a cleaner, more cohesive roofline and does not materially affect the character or appearance of the approved development. Consequential Amendments — Rear Elevation Windows As a consequence of the revised bifold door dimensions and the amended roof form, minor adjustments are proposed to the position and dimensions of windows on the rear elevation. These amendments are necessitated by the revised layout and are designed to maintain a balanced and considered composition on the rear elevation, consistent with the approved design intent. The overall character and appearance of the development as approved is maintained.
