Garden Office Guide: Energy Space


Continuing our Garden Office Guide we ask environmentally friendly garden office supplier Energy Space questions about their offices.

What is your most popular garden office design?

L model

Why does your design make the perfect garden office, how have you made it user friendly?

Our design makes the office environment extremely comfortable and healthy, with ergonomic layout, use of natural light, natural finishes that do not off-gas VOCs, passive solar design (solar gain in winter and solar shading in summer). They are user friendly with flexible interiors which include: bespoke built-in desks and workstations, shelving, additional windows, partitioned off storage, WCs, washrooms, even saunas or showers.

How do your garden offices comply with Planning Permission?

By remaining under 2.5m when being built near the boundary, up to 4m when 2m or more from the boundary and with a pitched roof. When planning is required though we are willing and able to submit applications on behalf of our clients.

What size garden office do you recommend for one worker to work comfortably?

2.5 x 3.5m

And for two workers what size garden office do you suggest?

3 x 4m

Are the foundations included in the price, if so what type?

Yes, Swift foundations

Are your garden offices suitable for year round use? What type of insulation do you use? How thick are your walls?

We super-insulate to exceptionally high standards, aiming for U values as low as 0.12-0.15, using a ‘warm roof/wall’ construction with 9″ of insulation. Our walls, roof and floor are around 12″ thick. This is reduced on the low roof models due to an unworkable reduction in ceiling height.

What is the exterior cladding on your garden offices?

We clad in UK grown larch, either vertically or horizontally, depending on the desired aesthetic. We are able to clad in cedar also although as it is imported from Canada there is a significant cost difference.

What is the roof covering?

Cedar shingles for the pitched roof version.

Roofing felt, rubber or sedum options for the flat roof versions.

What is the interior lining and floor covering?

Interiors are plaster boarded or ply-lined. The floors have a solid bamboo flooring laid and a stained ply option is also available.

How many electrical sockets do you include as standard?

4 doubles on the smaller units, 8 or 12 on the larger units.

What sort of lighting do you use in your offices, why have you chosen this type?

We use ceramic wall up-lighters with CFL bulbs as these provide non harsh ambient lighting while additional lighting can be added by the client as and when they need, for example desk lights.

Do you include heating in your garden office as standard, if so what type?

A programmable fixed wall heater is included as standard.

Broadband and telephone are important in a garden office, how do buyers get these to the office?

We run electricity to the building at no extra cost provided the house fuseboard has space for additional fuses. When laying this cable we add broadband and telephone cable at a small additional cost.

What optional extras would you recommend to create the perfect office setup?

A decked area and an oasis of planting around the building to create a healthy, vibrant and inspiring workplace. Indoors, extra windows and roof lights to bring in more natural light. A partitioned off WC and sink area, perhaps a kitchenette too if space allows. Solar panels on the roof allowing for carbon free working and an additional income through the Feed in Tariff.

What is the lead time on your garden offices?

6-7 weeks

What is the typical on site build time?

3-4 weeks

How much does a typical one person office cost?


How much does a typical two person office cost?


Are there any hidden extras? (planning fees, electrical hookup etc)

No, we aim to include all of the standard costs in our package, meaning the costs which occur on EVERY build: Foundations, electrical hookup, etc. Optionals are those that occur sometimes: water/drainage hookup, planning fees, roof lights etc.

What is the lifespan of your garden offices, is there any ongoing maintenance?

25 years, maintenance is required for general wear and tear, ie repainting interior, unblocking gutters. If this simple care is kept up then the building will run and run.

What guarantees come with the office, are they free?

We offer a 2 year free guarantee with our offices.

If you could give a buyer one piece of advice about buying a garden office, what would it be?

Ask for information on the stated U values. A garden office is essentially a 6 sided box and the lower the stated U value, the thicker the wall, roof, floor or window will be, meaning less heat loss, energy cost and carbon emissions. And a more comfortable environment for the user. You are hopefully only buying this once!
