Prices from £14,958

The Haven, from 3.7m x 3.3m

The Haven offers a recessed decked step on two sides in its classy and bright design.  The room is available in with grey or black trim as well as matching your cladding if you prefer.  

Exterior finishing

The modern profile, vertical exterior finishing is made from tanalised and pressure treated Scandinavian Redwood as standard. Please see our finishing section for the many other cladding options available.

High Quality Glazing

All our buildings are fitted with double glazed secure UPVC doors and windows. As standard we offer anthracite grey exterior colours and white internally however many other colours are available.  All doors and windows have excellent insulating properties.  The door and windows are also fitted with insurance grade locks, to provide the highest levels of security for your building and its contents.

Fully insulated

All our buildings come fully insulated to the roof, floor and walls for all year round comfort. Our 7-layer wall system ensures excellent thermal performance and breathability to enable you to work, relax or pursue your hobby no matter what the weather outside.


The Haven comes complete with a comprehensive electric package including a mains consumer unit, 3-bulb adjustable tracklight, 2 x recessed white double sockets and a lights switch. All wiring is concealed within the timber framework.


Installation is included and typically carried out in 2-3 weeks by our exprienced installation team.  We take great pride in completing the installation with minimum fuss, disruption or mess.


As standard we show our prices without foundations because some customers have pre-existing patios or concrete bases on which to install.  If you would like Blyss to install the foundations we use a combination of screw piles and pad foundations depending on the ground conditions.  Please see our construction section for more details.

Exterior finishing

A wide variety of exterior finishing options are available.  You don't have to have the same material on all 4 walls.  In many cases we install the "premium" finishing on visible faces and choose a lower cost solution for sides that are not visible.

Our lead installer, Andy, loves talking about wood and wood finishes so please make sure you have a consultation with him to ensure we help you to choose the perfect solution for you.

For full details and images of the finishing available please visit our exterior finishing page.

Windows & Doors

As standard we supply all windows & doors as long lasting UPVC models factory finished anthracite grey on the outside and white on the inside.  If you would prefer a different colour please let us know and we can discuss the many options available.

Additional windows are available on all buildings, ranging from small windows to add light and ventiation up large full height panels.  We are happy to quote for any combination of windows you prefer.

Doors may also be upgraded with many sizes of sliding door, french doors and bi-fold doors available.  Aluminium doors and windows are also available on request.

Decking options

The Blyss Pod and Classic come without a front decking step as standard but we will be pleased to offer one made to match your cladding, or from a complimentary material on request.  You can see some examples in our gallery.

If you would like us to install a larger decking area as part of the build, just ask and we will be happy to quote for a bespoke decking size.

Outside lights

Many customers ask for an external light to be fitted to provide security and to increase the elegance of their building at night time.  We offer brushed chrome "up and down" lights but will be happy to discuss other options.

Recessed spotlights

As standard the Retreat comes equipped with a 3 lamp tracklight.  We are pleased to also offer recessed LED downlights if you would prefer.

Interior wall finish

The standard finish in all buildings is a melamine faced board with a soft white finish that allows easy maintenance.  Rooms come complete with skirting boards and white vertical strips that hide the junctions between the boards.  We also offer unpainted mdf as a finish should you prefer to add your own touch of colour.

For a premium interior feel you may wish to upgrade to a plasterboard and skim coated finish, just like a new build house interior for you to add whatever paint finish you would prefer at the end of the project.  We are also happy to quote for a fully painted finish to the interior, but please be aware this significantly lengthens the build process as we must wait for the plaster to fully cure before decoration.

Heating & Cooling

The insulation performance of the rooms is so effective that in most cases only a small heating unit with a timer, or a smart plug that you can control from your phone is sufficient to keep the room liveable all year round.

We offer free standing oil filled heaters, or if you prefer we can fit low profile wall mounted heaters.

We are also please to offer air-conditioning units should you require extra cooling.  These may also be retro-fitted if you discover after using your room that sitting with the doors wide open enjoying the breeze isn't quite enough!


Our team keeps fully up to date with COVID-19 requirements and will ensure that appropriate social distancing measures are taken throughout the process

Do you offer a guarantee?

Yes, all our buildings are guaranteed.  Please refer to the warranties page for more details.

Is mains connection to the house included?

No - the price does not include connection of the mains electric to your Garden office.  We can arrange for this connection to be completed, however it is subject to site survey and you may find that a local electrician will provide the most cost effective solution.  The majority of mains connections can be run overground using armoured cable but if a trench is required this must be arranged by yourself.  We are happy to advise on the process and requirements.

Can you do a site survey?

We are happy to conduct a free site survey.  Why not call to arrange an appointment?

What about internet access?

Customers generally use one of two methods to enable WiFi in their building.  The first method is to use a Powerline adapter that uses your mains electricity lines to pass data.  You simply plug the adapers in next to your router and one in your garden room and a WiFi network is created.  Alternatively, many customers choose to run an ethernet cable alongside their power cable when connecting power to their garden room.  This provides a higher speed solution to the powerline option.

Can you install in a sloped garden?

Our standard foundations can cope with up to 300mm of slope without any trouble.  If your slope is greater than this, don’t worry, we have many solutions available and will be happy to advise.

Do you supply finance?

Not at this stage.

Do you send brochures?

We are a small company that tries to provide very competitive prices to it’s customers.  Big glossy brochures are expensive and not very environmentally friendly so we prefer not to produce them.

Can you fit decking?

We have a wide variety of decking available, both wood and composite.  Let us know what you have in mind!

Who will build my studio?

The studio will be built by our proprietor, Andy, and his excellent team.

What are your payment terms?
  • A non-refundable deposit of 25% of the full purchase price is payable upon order

  • 45% of the full purchase price is due as cleared funds 3 weeks prior to the agreed installation date

  • 25% is due as cleared funds strictly on or before the last day of installation of the building

  • 5% balance payable on full satisfactory completion

What is your returns policy?

Every room that we manufacture is individually specified and personalised to each customer’s choices. Therefore, a Blyss garden room, office or studio is a non-returnable item once your order confirmation has been issued and the 14-day ‘cooling off’ period has been reached. 

Can you create a custom-size building?

Yes!  The prices indicated on the website are for the more standard sizes.  If you would like something different just let us know.

Can I have underfloor heating?

Yes, we do offer underfloor heating as an optional extra.

Where do you install garden rooms?

We install our garden rooms across Mainland UK.  Delivery and installation is FREE within 100 miles of our office in Middlesex, HA6. Delivery or installation surcharges will be applied for sites outside 100 miles.

Can I live in my garden room?

No, our garden rooms are not designed to be lived in as they do not comply with building regulations.
