When you're considering the construction of garden rooms outhouses, conservatories, extension or garden offices certain size limitations often determine whether you need planning permission. Here's a summary of common size-related criteria you may need to consider when seeking permission to plan.
The planning permission is required for an outbuilding detached when it is more than 50% of the land area surrounding the original home (excluding its footprint).
Height Restrictions
Single-story buildings The maximum eaves height must not exceed 2.5 meters, and the total height must not exceed 4 meters for a dual-pitched roof or 3 meters for any other type of roof.
The maximum height of structures that are not more than 2 meters high is 2.5 meters.
Floor Area:
If you don't require approval for planning, but your structure has a floor space that is greater than 30 square meters and is required to obtain approval from the building regulation.
Proximity of borders:
Planning permission is typically required for buildings that are within 2 metres of the property's boundary.
Building Use
While it is not a strict size limitation, the intended use of the gardenroom may determine whether planning permission will be needed. If, for instance, the structure is intended be used as a place to stay for residents or to manage a small-scale business, then planning permission could be needed.
Permitted Development Rights:
Permitted Development Rights (which allows for certain types of work to be completed without the need for full planning applications) are subject to specific size restrictions and terms. The rights vary based on the property's type, whether it is a conservation area and/or subject to other limitations.
Conservatories, extensions, and other types of conservatories:
In general, for a single-story extension at the rear of a detached home the maximum depth is 4 meters and for semi-detached homes or terraced houses it's 3 meters. The depth can be increased to 8 meters or 6 meters, according to the Neighbour Consultation Scheme, subjected to certain conditions.
The height of an uni-story rear extension cannot exceed 4 metres.
Side Extensions:
Side extensions shouldn't be larger than the house in which they were originally built and shouldn't be any higher than 4 metres.
Volume Restrictions
In certain areas (like conservation zones or Areas of Outstanding Natural Beauty), any additional building which increases the size of the original house by more than 10% or 50 cubic metres (whichever is more) might require planning permission.
Front Extensions
Planning permission is usually required for extensions that extend past the front facing the road that was the initial home.

What Planning Permissions Are Required For Gardens, Rooms, Etc. In Terms Of Limits On Height?
The height of garden rooms and conservatories as well as outhouses, office buildings or extensions will determine if or not a planning permit is needed. Here are the top concerns regarding height that you should keep in your head:
The height of a detached outbuilding or extension must not exceed 4 meters with a dual-pitched roof (such as the gable roof).
If you have a flat roof, one-pitched roof or any other kind of roof, the height limit must not exceed 3 meters. The maximum height for any type of roof (flat or single-pitched) is 3 meters.
Proximity to boundaries
The height limit is 2.5 metres if the structure is located within 2 metres of your property boundary. This is the case for garden rooms, sheds and similar outbuildings.
Eaves Height
The maximum height of the eaves (the space between the smallest part of the roof and the eaves) cannot exceed 2.5 metres for any building.
Conservatories, extensions and other kinds of conservatories:
For an extension to the rear of a house with only one story the maximum height is four metres. This includes the roof, as well as any parapet walls.
Side Extenders
The side extensions must be four meters tall and can not be wider than half the original house.
Special Roofs
Structures having a flat roofing are usually restricted to 3 meters maximum.
Additional restrictions on designated areas:
In areas of Outstanding Natural Beauty Conservation areas, zones of Outstanding Natural Beauty and other designated zones, there may be stricter height restrictions and planning permission required for structures which would normally fall under allowed development rights.
Constructions in National Parks
Like designated areas structures within National Parks may have additional limits on height that require approval for planning.
Roof Design:
It is important to consider the size (excluding chimneys, antennas, etc.). must be taken into consideration. When the maximum point goes over the permitted limits of development, planning permission is required to be obtained.
Neighbours are too
Planning approval is required even if the structure is not over the height limit. This may be necessary if there are significant impacts on sunlight, privacy or views of neighboring properties.
Maximum Height:
The total height of a structure should not exceed 4 meters. In this case, the highest point of a garden-office with roofs that are pitched in two places should not be more than 4 meters.
Decking or Platforms
Decking and platforms attached to the structure cannot raise the floor to more than 0.3 millimeters to not require permission for planning.

Waste Management and recycling:
The planning permission could include requirements for waste management throughout construction and afterward recycling. To reduce the environmental impact, it's crucial to have sufficient provisions for recycling and waste management.
