Enter the dimensions of your planned extension. You can do this in 2 ways:

1. Move the slider under the size box to the length you require
2. Type the exact mensurment into the size box, or Use the toggle buttons to increase or decrease the length as required

The walls that can be altered are:

1. Wall 1 - the width of the extension which abutts the existing house
2. Wall 2 - the lenght of the extension as it protrudes from the house. In the case of an L-shaped extension this will also return beyond wall 3
3. Wall 3 - this is the existing house wall that the extension is build against

Defines the number of floors in your extension

The roof type you have on your extension may well be governed by the type of roof on the existing property, especially on a two storey extension.

This is usually due to planning permission laws which will not (usually) allow radical visual changes to a property.

Discussion with your architect or local planning office will resolve this issue. For the purposes of this quote a rule of thumb is:-

If the roof of your extension is easily visible by the public from two or more sides, choose a roof type which matches your existing. If the roof is visible by the public from only one position or only visible by neighbours advantage (through windows and back gardens) then a flat roof should be fine.

Price Doctor currently caters for square or rectangular and L-shaped extensions. If your extension goes around 3 sides of your home then choose the L shaped extension. You will then be able to extend Wall 2 so that it reaches beyond Wall 3 (the existing house) to create the L-shape.

To create an L-Shape extension:

• Set the dimensions of your extension, ensuring that wall 1 extends past the existing property to the desired length
• Set dimensions for walls 2 and 3
• Select the number of floors and type of roof you would like
• Under Extension Shape, select L shaped
• Now adjust the length of Wall 2, to the length of your L shape

Your new extension will generally need to match the existing building so choose the brick/stone accordingly. Do not worry about the colours of the bricks/stone in the images; it is the type of material that matters.

Think about the number of fixings you will have in the walls and how much you want the to be insulated.

Stud walls are easy to fix to if the studs are in the right place which takes a lot of planning. You will almost always need stud walls upstairs as block walls need to sit on a concrete slab.

If you want all pipes and cables hidden then stud walls are the way to go but remember they need to be planned carefully so all the timbers are in the right place

The cavity size of your extension will usually depend on the size of the cavity in your existing property. Wider cavities have been introduced since the standard 35mm in the 1950s to accommodate more (and better) insulation as the regulations now focus on the Governments pledge for 0 carbon by 2016. The standard cavity in new homes now is 100mm for masonry construction.

If you are working from an architect's drawing your cavity size will be shown. If you are working in advance of a drawing the standard width of a cavity is usually 75mm. This is set as the default width.

Whether a cavity is partially filled or fully filled will depend on the insulation requirements for your particular property including insulation calculations used such as the area of window space. You should discuss the options with your architect or local council Building Control Officer.

For the purposes of a quote however you should choose a fully filled (100mm) cavity with soft insulation as this is the standard way today.

Expolre this question with your architect and local Builders merchants, You must decide if you want to be green, or traditional.

Usually it is best to use an insulation with a refelctive skin such as Kingspan but some local authorities insist on an air gap also to avoid condensation.

How will the ground floor be constructed? E.g. timber, concrete etc....

This choice will usually depend on the type of flooring you have in your home or the standard of insulation your architect is trying to achieve through the floor construction as well as choices like underfloor heating (included later). Discuss the options with your architect or the Building Control Officer at your local council.

For the purposes of this quote it would be as well to choose an insulated concrete slab as this is fairly standard construction.

Traditional (had built) roofs accommodate for features such as dormer windows, large roof valleys, multi hipped roofs and other non-standard features.

If your pitched roof has a simple two-slopes (one front, one back) then trusses are by far the cheaper option.

If the roof has any of the features described above, discuss the roof construction with a truss supplier to see if it can be incorporated in a bespoke truss section. If not it will need to be hand-built by a roofing carpenter.

Solar panels may help with the cost of your bills and you can experiment, by returning to this tab at the end, to see how much it would cost to have various sized areas of you roof covered with solar panels.

Most domestic solar installations are between 3 and 6 kW which takes up a roof area of between 28 and 56 square metres.

Solar panels work at their best when they have sun all day long so in most cases they will only be present on the south facing side of your roof or the section of roof that gets the most sun for the longest period of the day. In most cases they will not be placed on both sides of your roof.

Usually guttering is chosen which matches the existing however this may be a good time to replace all existing guttering with a larger diameter or a different design especially if you are having a new soakaway dug.

It is as well to gain the maximum amount of storage space but it must be remembered that a loft, unless designed by an architect to be a room, is purely for storage and it is unsafe to use it as anything else.

If you have storage space, you must obviously have access so make sure your builder has included for a loft hatch.

Unless you are investing in a rainwater harvesting system it will be a good idea to find out how your rainwater is dealt with now. If it is drained into a soakaway you should have a new soakaway provided for the new gutters etc. If it goes to an existing main drainage system this should cope with the additional water.

These need to match your existing property. It is quite usual for the roofer to remove the old tiles from the back of your existing property to place them on the front of the new extension. These are then replaced with new tiles and the back of the new extension is tiled with new tiles also.

This allows the front of the property to have a colour continuation at roof level and is included for in these prices. Talk to your builder about this.

The more difficult it is to get materials, lorries etc. to the site the more expensive the job becomes. Ask yourself how easy it will be to get heavy materials to your extension. Will gates or walls need to be removed? Will the builders need to walk a long way with heavy wheel barrows full of earth or concrete? How close can the skip lorry get? Is there anything you can do to make access a little easier for the builders?

Does your new extension block out all of the light to an existing window or make a doorway redundant? If so you could consider bricking it up to give yourself more wall space both in the extension and in the existing building. Price Doctors quote includes all insulation and plastering to the bricked up opening so make sure your builders does.

Unless you are installing a new septic tank then it may be as well to use the system you are already connected to. If this is a septic tank however, check with the tanks manufacturers or your architect that the tank you have can cope with the additional waste.

Remember the drains from your home form part of your deeds so pipes cannot just be installed without permission and connection to mains sewers requires building regulation approval.

How many TV aerial sockets do you want in each of your rooms. Remember, you will also need an electrical socket next to your aerial socket to plug in TV's, DVD's, Satelite boxes etc....

If two light switches are chosen for one room, it is assumed that they will be on a two way circuit. However the cost differential between a one and two way circuit here is not great so if you are unsure, choose two switches.

The Price Doctor quote includes for all necessary wiring to each new fitting but only includes for connection to an existing consumer unit. If a new consumer unit is required, this will cost you extra and you should check this with your electrician before work commences.

It is as well to have more sockets and other electrical fittings put in than you think you might need. It is far cheaper to install them at this stage than it would be afterwards.

Do you want to have door closers on your doors?

In many extensions, especially 2-story extensions, door closers will be required under fire regulations. Please check with your local authority if you are in doubt.

Choices of skirting boards may depend on those fitted in other rooms in your house. If your existing skirting boards are not an “off the shelf” type, you should get a price from either a local joinery shop or carpenter.

How high should your skirting boards be and should they be painted

You will need to check with a heating engineer or plumber to see if your existing boiler can cope with supplying heat or water to the new extension.

It is rare for a boiler to be at maximum performance when working in a domestic dwelling but if the house has been extended already or you will be making great demands on the boiler (E.G 10 new radiators) you may need a new boiler.

It will also need to be a condensing boiler.Price Doctors quotes include for all fitting, testing and the issue of Gas safety certificates.

The distance from radiators adds cost to the extension as more pipework and fittings are used.

Boilers can be very unsightly and boxing in is not a huge expense. IS THERE A RESTRICTION HOW FAR FROM AN OUTSIDE WALL BECAUSE OF THE VENT? Check your boiler installation manual for maximum flue distances

Choices of coving may depend on those fitted in other rooms in your house. If your existing coving is not an “off the shelf” type, you should get a price from a plastercraft or mouldings specialist.

Do you need to construct a new opening to get from the existing to the new? If so, this is called a knock through.

If you have more than one knock-through in the same wall there must be at least 400mm in between them to sit the lintels on so make sure you have enough wall space for this.

The Price Doctor price includes for doing all of the making good after the knock through is complete and lintel construction and size should be checked by the Building Control Officer of your local council as you need Building Regulation Approval to remove all or part of load-bearing walls.

Now is the time to choose under floor heating if you want it. If you choose under floor water heating it may be as well to revisit the new boiler page and consult an engineer to see if your existing boiler can cope with the new demand.

The Price Doctor quote for all items seen on this page includes for fitting and the work being done to completion. We have also given you the option of including a stated amount that you expect to spend on beds or other furniture.

This will give you a good indication of how much the build will cost in total as it is easy to forget that new rooms need to be furnished!

See the list of materials that you will need for your build broken down into the phases of the project. You will also be able to see the quantities and prices for each item needed.

This is very useful for integrating builder’s quotes and for spotting areas of potential savings or areas where you will not compromise on the quality of materials. If you plan to do some or all the work yourself, or if you’re going to source some of the materials for your contractor you will need this list.

Find a list of all the man hours that will be needed for each phase of the project. This is broken down by the skill or trade so you can see how much and what kind of labour you need and when you will need it.

If there are elements that you want to do yourself, you will see the time it would take to complete the task. Use this to help integrate quotes that you receive, or to see where time (and potentially money) might be saved.

This is where you can amend the pricing for your project, and your account. This is recommended for professionals (and serious self-builders) only.

This allows you to change the material and labour prices to reflect those that you have negotiated yourself with your suppliers or sub-contractors so you can prepare accurate quotes for the project you are working.
