Garden room and home office air conditioning in Holloway
For a garden room in Holloway, the outdoor unit usually sits on a small stand behind the building. London's dense streets hold heat overnight, so top-floor flats and loft rooms often stay warm long after sunset.

Planning and permissions
Since 29 May 2025, England's permitted development rules allow larger outdoor units (up to 1.5 m³) and no longer require a 1 m gap to the boundary, provided the MCS 020(a) noise check is met. Listed buildings and pitched-roof installs still need permission.

At the survey we look at how each room is used, where the sun hits it and how the pipes can reach the outside wall, then put it all in a written quote. We book surveys in Holloway at a time that suits you, including early evenings by arrangement, and send the written quote afterwards.
