What Is a Permitted Development Extension?
Permitted development lets you add space – without a full planning application. If your project meets size, height, and location rules, you skip the council queue entirely. We handle everything to make it happen: architectural drawings, structural calculations, construction drawings, and the build itself. One team. No gaps. No guesswork.
Permitted development extensions are commonly used for:



Wraparound extensions
Combine rear and side extensions for significant space gains, carefully designed to stay within PD allowances.



Single storey rear extensions
Maximise living space with a compliant rear extension designed to meet PD depth and height limits



Side return extensions
Ideal for terraced and semi or detached homes, turning unused side space into functional living areas.


Loft conversions (subject to criteria)
Create additional bedrooms or offices under permitted development rights where applicable.
Designed to comply. Built to last.
Every extension we design stays within permitted development limits – no guesswork, no risk. Where required, we secure a Lawful Development Certificate: legal proof your project is fully approved before a single brick is laid.
