Q

conservatory or extension

I need to extend the living room, which is long and narrow (7m x 2.5m) but I don't know whether I am better off with a conservatory (3x3) (already posted job quotation request) or a proper extension (7x2) with 2 Ftrench windows. What is the difference in cost? I'd rather have an extension. Would I be able to have one done, (with all electrics, plastering, French doors etc)for under £15000? Thank you

Q

Best option for sound proofing with new extension

Hi,

I'm planning on starting on a rear extension next year, I live in a semi detached and with me watching boxing / mma most weekend majority in over seas so it's usually on until 05:00, as you can imagine next door are not very happy when surround sound is on during this time.

The extension is hopefully going to reduce the noise level, but I would like to know if there was anything "extra" I could ask the builder to do to help more with reducing so I can enjoy the night instead of worrying about noise level.

*** Ian could you please send pictures to tornadot1979@aol.com thanks in advance for advise ***

Thanks in advance.

Mark

Q

Single storey extension in EX5 area of Devon

We have planning permission for a single storey extension & are horrified at the price's we have obtained so far. We have four quotes in region of £43.000 to £83.000! the size is 4m x 6m, This does not include a kitchen just a utility (plumbing only, no sink) cloakroom & sitting room, nothing fancy at all. I cannot think how anyone can afford to have an extension to their property at these prices, let alone a two storey extension! Am I expecting too much? I am about to sell on the house as I have given up trying to get this done. The costs will exceed far more than the house is worth, even with the extension :( Thanks guys & yours are london prices! Going to be a bit of a slog trying to find a good honest chappie.

Q

Where do I start with planning a single storey extension? How much should I be paying for architects plans?

I live in an average sized semi detatched house. I am planning a small single storey extension at the side of my house (approx 10m square) to extend my kitchen. I have done some research on the internet and looked at previous questions on here, but it's actually thrown up as many questions as it has answered!!
I'm not sure where to start as I don't know exactly what I want (just a kitchen extension or a smaller kitchen extention and separate utility room?) I don't know whether to get some building quotes first for a rough estimate or get plans drawn up first (will architects actually give me advice on what to have done or do I need to tell them exactly what I require?)
Also, I'm unsure if I need planning permission because although the extension is only small it will be going right up to my garden boundary. Do architects advise on this? (I don't want to pay for plans only to find I can't build what I want to).
On that subject, roughly how much would plans cost from an architect? (also, I've read on other websites that you can use a technician instead of an architect to produce plans. What is the difference?)
I understand the concept of planning permission, but I also keep reading about planning notices, certificate of lawfulness and building regulation fees. What are these and do I need them, or are they covered by planning permission if I get that?
Roughly how long will all this take, and how long to build the extension itself? (I am looking ahead to how much time I will need to take off work to be at home whilst the building work is carried out)
Sorry there are so many questions, but any advice on any of my questions would be appreciated. I will be looking for quotes from tradespeople on this website once I am ready to go ahead with this work (hopefully this April/May/June time)
Thanks very much, Janice

Q

Does anyone know of a user friendly estimating software for extension or small build costing that is designed for a small to medium sized company?

I'm looking for software to speed up our internal quotations for extensions etc If anyone uses a particular software key benifits would be greatly recieved.

I'm not looking for abuse such as KTL is giving. The software is for use by office staff to speed up the estimating process. I personally do not have the time to quote for the ammount of work we have come in verses management of staff, and material organisation, running the two maintenance contracts we have and also dealing with the day to day running of a growing business. This question is asked to professionals who see the benefit of such software. If I were a one man band flying around in a transit doing a few jobs a month, it's easy to deal with the quotation process and manage to work on the tools with the only headache being finding the nearest butty shop, but i'm a little beyond this now and there are not enough hours in the day!! I'm sure a professional can understand this.

Thanks for your input guys, and taking the time out to suggest some software, i'm sure your very busy and I appreciate it.

Q

Can a conservatory be converted into a extension?

I have an conservatory, about 7 years old, dwarf wall, and I wondered if to cut the costs it would be possible to convert this into a single storey extension. I dont know the dimensions, but from knowledged the footings looked quite substantial, the floor is solid concrete. My thought was, remove the glazing, continue the drawf walls to full height and put on a roof.

I would guess this, if possible, would greatly reduce the cost of an extension

Q

What are the options with the single skin extension on my house?

I have a single skin extension on the back of the house we bought, previously used as a utility room and we want to convert this into part of the kitchen. If we insulate it from the inside will it still show up on future surverors reports as a watch out for buyers? Can you let me know if insulating from the inside is worth it?
