What affects the price of a garden office on a Chorleywood plot

Size sets the starting point, but the plot decides the rest. On a typical Chorleywood garden the biggest swings come from foundations, the length of the power and water run, and the route materials take to reach the back lawn.

Before you compare quotes, check that each one covers the same things from this list, cheapest to dearest: size and height, foundations: ground screws, pads or a slab, cladding and roof finish, amount and type of glazing, distance for power, water and drains and access: can materials reach the garden?. A quote that leaves one of these out is not the same job as one that includes it.

As a worked example, a medium garden office with air-con and extra glazing / roof lights comes to £21,000 to £36,000 in the calculator. Use the cost calculator to build your own combination.

Planning in Chorleywood: check before you build

The national register lists 3 conservation areas within about 1.5 km of the centre: Chorleywood Common, Chorleywood, Station Estate and Heronsgate; on designated land such as a conservation area, an outbuilding at the side of a house needs planning permission. The Chilterns National Landscape (AONB) reaches to within about 1.5 km of the centre, so check whether your garden falls inside it. Green Belt land lies within about 1.5 km; Green Belt does not by itself remove outbuilding rights and matters only if an application is needed. The Article 4(2) direction for Chorleywood Common covers windows, chimneys, front boundaries and hardstanding (Three Rivers District Council); its page does not mention outbuildings, so check your street with the council.

Planning applications in Chorleywood go to Three Rivers District Council. If you are unsure, ask the council or apply for a lawful development certificate, which confirms in writing that a design is permitted development.

What your builder checks for your plot

The height of the room, and how near it is to your boundary
How far it is from the house, and its floor area
Whether your home is in a conservation area or listed
Whether anyone will sleep in it, because building regulations then apply

General guidance, not legal advice. Check the rules on the Planning Portal and with Three Rivers District Council.

Planning a garden office in Chorleywood: points for this room

Most garden offices fit within permitted development if they meet the height, position and size limits.
If any part is within 2 m of a boundary, the whole building must be no higher than 2.5 m.

New circuits for power and lights are notifiable under Part P, so use a registered electrician.
