As experts in property, LPS Architecture have a proven track record in gaining permission for Single Storey extensions. Whether you want a simple extension or something a little more special you can trust our specialist in-house architectural designers to produce the results. From design concept to project support we are with you every step of the way.

Everyone loves options, and with single storey extensions you have 3 key routes to getting what you want.

Permitted Development Rights: These rights are applicable for side or rear extensions with a length of 3m on a terrace/semi detached or 4m on a detached property. This still requires plans to be submitted to your local council for a certificate of lawfulness.

The Larger Home Extension Scheme: A Free application that is applicable to householders who want to extend the rear or side of their property up to 6m on a terrace/semi detached or 8m on a detached property, subject to certain limits and conditions being met.

Planning Permission: Extensions that do not fall within the above categories or policies will require full planning permission. 

Our Process

Transparent Fees

Please note: We offer a discount for clients who want to do more then one extension on a property (e.g loft conversion and rear extension)
