Local garden office builders in Berkhamsted

Every builder we work with is insured and established: public liability cover and three or more years trading.

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

Two garden offices of the same size can cost very different amounts. In Berkhamsted the difference usually comes from the plot rather than the building: how far the room sits from the house, how level the ground is, and whether the builder can get materials to the back garden without crossing the house.

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 Berkhamsted: check before you build

The national register lists 2 conservation areas within about 1.5 km of the centre: Berkhamsted and Northchurch; 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. No register entry within that distance removes the outbuilding right, but the register can be incomplete, so check your street with Dacorum Borough Council.

Planning applications in Berkhamsted go to Dacorum Borough 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 Dacorum Borough Council.

Planning a garden office in Berkhamsted: 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.
Using it as your own home office is normally incidental to the house. Staff, clients or customers visiting may change that. Check with your council.
Under 15 m² with no sleeping space, building regulations do not normally apply.
New circuits for power and lights are notifiable under Part P, so use a registered electrician.

Permitted development limits for a garden office in Berkhamsted

Whether a garden office in Berkhamsted needs planning permission depends on a short list of limits set nationally for outbuildings. If your design stays inside all of them, you normally do not need to apply. If it goes outside any one, you do.

It must be single storey, with eaves no higher than 2.5 m.
It can be up to 4 m high with a dual-pitched roof, or 3 m high with any other roof.
If any part is within 2 m of a boundary, the whole building can be no higher than 2.5 m.
Height is measured from the highest ground right next to the building.
It must not sit forward of the front wall of the house (the principal elevation).
All extensions and outbuildings together must cover no more than half the land around the original house.
No verandas, balconies or raised platforms. A platform must be no higher than 0.3 m.
The use must be "incidental" to the house. A bedroom, bathroom or kitchen does not count.

Where the limits are tighter near Berkhamsted

Some land has stricter rules than the national limits. In Hertfordshire the ones that come up most are listed below. Whether your address is inside one is something to confirm with Dacorum Borough Council.

Conservation areas

An outbuilding between the side wall of the house and the boundary needs planning permission.

National Landscapes (AONB)

The side-wall rule applies. Anything more than 20 m from the house is limited to 10 m² in total. The Chilterns National Landscape covers parts of both Hertfordshire and Buckinghamshire, so check whether your address is inside it.

Listed buildings

Any outbuilding within the grounds of a listed building needs planning permission.

Flats and maisonettes

These permitted development rights do not apply.

Article 4 directions and old conditions

A council can remove permitted development rights in an area, or a past planning condition can remove them for one house.

Building regulations for a garden office in Berkhamsted

Planning permission and building regulations are different things, and a garden office in Berkhamsted can need one, both or neither. For building regulations the question is floor area and sleeping space. The bands below apply across England, including Hertfordshire.

Under 15 m² floor area

Building regulations do not normally apply, as long as nobody sleeps in it.

15 m² to 30 m²

Building regulations do not normally apply, as long as nobody sleeps in it and it is either at least 1 m from every boundary or built mostly of non-combustible materials.

Over 30 m²

Outside these exemptions, so building regulations approval is normally needed.

Any size with sleeping space

The exemptions do not apply once a room has sleeping accommodation.

Electrics matter whatever the size. A new circuit to a garden office is notifiable under Part P, so use a registered electrician or ask your builder who certifies it. Building regulations guide
