An Edwardian Conservatory: How Much Does It Cost?

By adding an Edwardian conservatory to your property, you will increase the value of your home while adding a touch of luxury to it. This new living space will be enjoyed for many years to come for a variety of events, celebrations and experiences. 

Why choose an Edwardian conservatory design?

By choosing the Edwardian design, your conservatory can complement either a traditional style structure and a modern home. It will provide you with a new space that is as luxurious as a Victoria era sitting room with the easy construction of a typical square or rectangular floor plan addition.

With the Edwardian design, there are few if any limitations. The incorporation of dwarf walls helps to make the new space look like it was part of the original structure. There is also the option of having floor to ceiling glass walls to maximize the sun’s rays penetrating the space.

How much does an Edwardian conservatory cost?

As with all things being constructed, the materials used will directly influence the cost of the finished product. The other major influence is the size of the new conservatory.

The most common sizes and costs for materials minus the roof and concrete slab of conservatories are;

  • 3.5 m x 3.5 m from £9,000 to £11,500
  • 3.5 m x 4.0 m from £11,500 to £14,000
  • 4.0 m x 4.0 m from £14,500 to £23,000

Polycarbonate roof price will vary from £3,300 to £4,300.

This is the least expensive and the lightest in weight. Because of the reduced weight as compared to glass and tile, the framing for the polycarbonate sheets can make use of lightweight UPVC framing material.

Polycarbonate is translucent, but not clear. This reduces the amount of the sun’s rays from entering the space. It also is not a great insulator so there is more heat loss during the cold winter months. Over time the polycarbonate also turns yellow due to UV damage from the sun’s rays. It can also be scratched from a falling tree limb.

Glass roof price will vary from £4,200 to £4,700.

This is the traditional material used for roofing of a conservatory. It is somewhat heavy so the frame holding it in place should be wood, steel or aluminium. Being double pained or glazed makes it a good insulator in the winter.

The finish is clear so the stars can be seen clearly on cloudless nights. On hot summer days, the room will need to be ventilated.

Tile roof price will vary from £6,300 to £7,300. When wood framing is used the price increase over UPVC is on average £4,000.

Tile is the most expensive option for roofing and is also the classic choice. This type has the best insulation qualities of the three types of roofing material. This makes it easier to control the temperature in the new room. It is also the insulator against noise for those that have noisy neighbours.

While less of the sun’s rays can penetrate the room, more lighting options are available without obstructing the view outwards since no one will be looking up. The framing is generally wood but metal can also be used. With the wood, the periodic painting of it will be required.

Choosing the type of wall

There are only two options when referring to walls. There is floor to ceiling panels and dwarf walls.

Dwarf walls

This is the traditional type used with an Edwardian conservatory. The typical footing is 60 cm high and provides a more stable base for the structure to set on that a simple glass panel setup. By the bottom of the glass panels being elevated from the ground, the amount of rain splatter mixed with dirt will be decreased on the glass. Because of the construction material, electrical outlets are also easier to fit into the new space.

When possible the same material for the main structure’s construction should be used for the dwarf walls. This provides a seamless view that makes the conservatory seem like part of the original structure and not a simple addition.

Glass panels

These are less expensive than dwarf walls and faster to put up. This is the preferred style if there will be numerous plants around the edge of the conservatory on the inside. While not as sturdy as dwarf walls, they do allow for more sunshine to penetrate the space.

The flooring

Before the concrete is put into place some planning on how you are going to heat the conservatory should be decided upon. Heating tubes can be placed in the concrete to supply the necessary radiant heat for the room. Another option is the use of heating tiles that will use electricity to heat the tiles to keep the space warm.

If you plan to use panel heaters, then all flooring options are open to you. Carpeting is the least expensive with a hardwood floor is the most expensive. Other options include vinyl, tile and laminate.

The downside of carpeting is that if you have plants out there, the carpeting can become damp and mouldy. With wood, it will need to be periodically recoated with polyurethane.

The base of nearly all floors of a conservatory is concrete. Once it is laid, it takes up to 8 weeks before it is cured. On average the cost is £95 per m2. This base should be as minimum 200 mm thick. Below is just the cost of the concrete. You should also expect to pay for labour so add another £1,000 to £1,500 to the prices below.

  • 3.5 m x 3.5 m costs £1,164
  • 3.5 m x 4.0 m from £11,500 to £14,000
  • 4 m x 4 m costs £1,520

Optional items that increase the cost of building a conservatory.

Access to water is important for those that will have plants in the conservatory. If that is true then a spigot should be installed. The easiest place would be on the wall where the conservatory opens into the existing structure.

The electrical needs of the new space should also be planned out before construction begins. When dwarf walls are being used, the wire channels can be incorporated into them so they can be hidden from view. Placement is your choice.

When glass panels are the walls, exposed electrical channels are used. The placement of the outlets is limited to the joints of the glass panels.

When privacy is a concern an option are blinds. The most common are the mini blinds. These are low in cost and can easily be put into rolled-up position during the day.

An exit door in the conservatory to the outside is also possible, but increases the cost of the construction. For homeowners that have a nice garden in the same space as the conservatory a pair of French doors is a common addition.

How much is the labour to construct the conservatory?

The cost of labour is dependent on who is doing the construction. Some places sell a conservatory as a type of kit since they sell so many of them. These places also have crews that can assemble the conservatory for you. Since this is the only construction they do, they are faster than a general contractor in completing the job. After the concrete is set, the assembly time will be from 8 to 15 working days depending on the specifics of the conservatory.

The price range of labour should be from £1,800 to £4,300. Since this is a substantial amount getting more than one bid is advisable. Of the bids you receive, unless you know the contractor the bid that is the lowest is generally not accepted. Many contractors will submit an exaggerated low bid to get the job, they add charges later once construction begins.

The total costs of an Edwardian conservatory

To total costs of adding a conservatory to your property must take into account the size of the addition, the concrete slab and its labour, the material to be used for the walls, the roof material and the labour to assemble the structure. This will place the costs from £16,264 for the smallest with polycarbonate roofing is used to £41,620 for the largest with wood framing and a tiled roof.
