Will I need planning permission to build a garden home office?

When installed within a back garden, most garden home offices fall under the umbrella of permitted developments and therefore do not require planning permission under building regulations. If building within the 2m boundary of your property you’ll have to opt for the default 2.5m height rather than our larger options. There are some exceptions, and it is always worth contacting your local council or planning authority with any questions you have about planning permission. In certain locations, you may require building regulations approval.

Why choose the adjustable frame

The adjustable frame is perfect if you have an existing hard standing area, or an old concrete pad. It is easy to assemble and can be put together by one person, therefore saving time and money on preparing the groundwork on an existing site. If you are starting from a blank canvas, you can either create a full concrete base to fully support the building, or construct 4 pads for the corners for the adjustable feet to sit on.

What groundwork is needed for the Box Office

The steel chassis can go directly onto an existing hard standing such as an old concrete pad or paving slab base. If it is unlevel – the chassis can be adjusted by up to 100mm, to ensure the frame is level.

If you are installing on a lawn – simply remove the top level of grass, and create four hard standing pads for the four feet to sit on. You will need to dig down by 300mm – then either fill with concrete / hardcore with a paving slab – or simply fill a bucket with concrete and drop into the hole. This can be easily removed in the future if required.

What groundwork is required for garden offices?

Concrete Pad or Paving Slab Base
150mm compact hardcore: DPM: 100mm concrete: or
150mm compact hardcore: 50mm paving slabs on cement sub base

Garden rooms and offices require a flat & level pad of either concrete or paving slabs.
The base will need to be at least the same size as the building you are looking to have, and you
will require 400mm clearance to objects such as fences, trees or other buildings.
We can work within a 10mm tolerance (which a competent builder can easily achieve).

What access do I need in to my garden for you to install the building?

We require a minimum of side access of a minimum width of 600mm and a height of 1950mm to allow us to install your building. Should you be concerned about access in to your garden please email us pictures of the access and we will be able to confirm whether it is suitable.

Is my garden room/office suitable for year round use?

The Garden Rooms and Offices are fully insulated for year round use. They are designed to be warm in the winter and cool in the summer, however the location in your garden will have an impact on how warm / cool the building is.

North faced gardens will have buildings that are naturally cooler throughout the year, whilst south facing garden will be naturally warmer throughout the year.

A building in the shade or in a north faced garden, will need a small heater during the winter months, but will remain cosy when the building is up to temperature.

A building in direct sunlight or in a south facing garden will benefit from more ventilation and blinds between the glass to keep the building cooler.

What makes some timbers more expensive than others?

Good forestry management requires the selective felling of trees which would otherwise gradually lose tensile strength over time and which would inhibit new growth resulting in forests which contain a lower grade quality timber overall. Careful forest management is a necessary practice to maintain balanced and healthy forests and should not to be confused with indiscriminate de-forestation which is seen in areas of the world particularly in regions where tropical rain forests predominate and which devastate wild life habitat and contribute to global warming.

How long will my building take to build on site?

Garden Rooms are usually constructed within 1-2 days (up to 6.2m x 3.6m sizes) depending on the final specifications.

Garages up to 6.1m x 6.1m are usually constructed within 1 day. Larger buildings will often take 2 days on site.

Commercial Buildings usually take 1 week on site – depending on the final specification.

How long will my building last?

We regularly have customers that have buildings re-roofed at 15 and twenty years old – who are quite confident that their buildings will last double that time if they get general maintenance and care.
This building was taken by a customer and we have worked out that it was 18 years old, and was still original. The customer has painted the building regularly with Protek Woodstain.

This garden office is 12 years old and has been regularly treated with Dark Oak wood protector. It features timber doors and windows, along with brown felt tiles.

Is tanalised timber waterproof?

Tanalised timber is not waterproof, so it is still subject to the natural expansion and contraction as the moisture content in the surrounding atmosphere changes. It advised that a water repellent (clear or colour) treatment is applied to not only maintain the appearance of the building but also to help to exclude moisture being absorbed by the timber surfaces.

Why is the groundwork not included?

Warwick Garden Rooms and Offices need a solid paving slab or concrete base to support the weight of the building over the complete area of the floor. This is known as a ground supported floor with the concrete pad classed as a floating pad which allows the natural movement of the ground conditions to change without compromising on the base. Ground supporting bases require the soil to be dug out, filling with hardcore and compacted down, before adding concrete or smooth slabs. Each base needs to be priced individually and done by a local builder due to the logistics of organising a skip, hardcore, concrete and access. Remember – this is not a garden shed…If you want your garden room for a long time, then you want the best base for it. And if you want the best base, then you want a concrete base.

Whilst we understand the customer prefers an all in one package, we have regularly looked at ways to suspended floors on small concrete pillars, provide groundwork teams, and design steel chassis as a way to do the whole job – however the cheaper alternatives being the steel chassis, and the pile foundations do not provide a strong enough solution as a base for a garden office. The base of your office or garden room is one of the most important parts of the building. Not only does it give your building a secure and safe place to stand, but it also protects it from flooding, pests, rodents, and other damaging elements.
To keep the costs sensible – a local builder will be able to provide a you cost effective price for a slab base, simply because the site requires an initial visit, preparation, removal of soil, and organisation of materials using local sources.

What is wrong with the steel chassis?
The steel chassis option provides a solid support around the perimeter, and has purlins across the centre to support the middle of the building. This construction will need ground supporting in the corners and at regular intervals under the purlins, hence the need for concrete piles to be installed and packed up so stop any bouncing. In theory this sounds like a good solution, however the steel ringbeam of the chassis will lift the building off the ground and therefore needs to be hidden from view adding additional cost to the materials of the garden room and the labour on site. The overall costs are usually greater as the labour on site to set up the chassis, plus the chassis itself quite often equate themselves to a concrete base cost.

What about the pile foundations.
Supporting the structure on small piles of concrete and plastic packers is a quick and easy way to create a level platform for the building to rest on, however this again needs an initial site visit, and some additional finishing off materials to hide the void under the floor.  Companies that include the groundworks within the price of the building can also hide the cost of the base within the building itself, which then begs the question – is a ‘quick base’ going to stand the test of time?

What about a wooden platform?
This is often the base that is provided by companies that build the structure completely on site. It isn’t a bad solution as the timbers used as the base will support the floor – however they are likely to be above ground level, thus impacting on the internal height of the building. This option comes down to cost, as the garden rooms that are built in situ are more expensive to construct on site, compared to a factory build, simply due to time taken to carry the components from the store to the can, and from the van to the garden. It may offer a finish that you ultimately prefer to see, however that essentially comes at an inflated cost.

 

How do I get internet to my garden room/garden office?

There are two ways to get internet to the new Garden Office.

Option 1 is to have a CAT 5 cable coming from a router in your house, down the garden and into the back of the building.
We can supply a back box specifically for a CAT 5 cable. Usually the cable is better to be unbroken – hence we don’t internally wire with a CAT 5 cable to pug into

Option 2 is to purchase a WiFi extender kit or a mobile data dongle.

Please explain the electrics?

Garden Rooms and Offices include the first fix wiring, along with the consumer unit, lighting and the faceplates.

All wiring is installed within the cavity and is ready for an electrician to connect the tail ends of the wiring at the consumer unit and the faceplates.

The electrician will need to provide and install a power feed from your house / garage to the new building – usually a 6mm armoured cable is used. The wiring provided is 1.5mm cables for lighting on a 6 Amp fused circuit, and 2.5mm cables with a 32 Amp breaker for the sockets – on a ring main.
There is space for a 3rd breaker if it is required for another feed.

It usually takes half a day for the internal connections, plus the time required for the electrician to install the cable that you require.

Our electrician can offer customers in Warwickshire and Worcestershire with installation and certification independently – please contact him directly (Andy Punnett) via his website www.aspelectrics.co.uk If you live in Berkshire or Hampshire, please contact Ben Thorp on 07917 131984

Please explain the cladding options available?

Shiplap – 16mm x 125mm Scandinavian Redwood machined to our unique profile, with an extra long rebate to allow for natural movement of timber. It is pressure treated to a light green colour to protect against rot & decay for 15 years and is the ideal choice for customers who like a smooth finish and little maintenance.

Feather Edge – 25mm x 150mm home grown spruce with a sawn finish, that provides a much thicker and heavier look to the shiplap. Again it is pressure treated in a light green colour, and is the ideal cladding for customers looking for a traditional looking building that is full of character. The size and weight of the feather edge along with the manufacturing processes mean that this board is a more expensive option over the shiplap cladding.

Cedar – 12mm x 100mm Tongue & Groove cladding machined to create a modern looking finish. Each board is unique as this beautiful cladding naturally ranges from a dark hardwood to a light pine in colour thus creating a fantastic looking natural building. The hardwood properties of Cedar mean that it hardly expands or contracts during changes in weather, whilst it also has it’s own unique protection against rot, decay and insect infestation. Whilst the Cedar will fade in the sunlight, it is a must for customers looking for that wow factor on a garden room or garage, and it will continue to offer that feeling especially if protected against UV rays with Restol Oil.

How much clearance do I need around my building?

We require a minimum of 600mm around the building to be able to fit the cover strips and guttering on the outside of the building.

If you have less space available please contact us on 01926 815757, as we will discuss the options available on an individual basis – it may be that we can still accommodate your project.

What can I have without planning?

Buildings close to a boundary will need to be 2.5m high. If you require a taller building without planning you will need to be more than 2m away from your boundary.
You will need to locate your building either to the side or to the back of the house – buildings in front of the house will need planning permission.

Please note that the customer is responsible for planning permission, and may need to contact the council for full clarification of their permitted development rights.

What maintenance is required?

The weather, location and the sun can all have an effect on buildings, however throughout our 35 years we understand how our product works and how it stands up to the test of time.

Your maintainace schedule should be:

  • To clean the gutters out to keep free from debris
  • Adjust doors and windows that have expanded or contracted through weather conditions
  • Remove debris from the roof
  • Treat the outside of the building as required to maintain an attractive appearance. (This provides a waterproof coat to the timber and keeps the moisture content of the wood consistent – which in turn improves the stability of the timber, and reduces the expansion & contraction of the timber)

Our guarantee is in respect of design and maufacturing faults, corrosion and rot for 10 years from the date of installation.
