I've got a bunch of rough stone that I dug up in my garden, and I'd like to build a wall as a landscaping feature. I've heard different views on whether to use a cement mortar mix or a lime one. Wondering what people out there think, and why.

tiles keep coming away from plywood that boxes in pipe work

i am going to have a new combi boiler installed and i was wondering how much i could fetch for the cylinder and pipework and is worth me selling or letting the trademan taking it.

I'm having a new extention built which will include an ensuite and a new combination boiler.
I have noted that the builder has used plastic pipes connecting to some copper pipes using push on connectors, also some plastic pipes are reccessed into the brickwork and will be used for a radiator. Is this now common practice? In my day it was all copper pipe. Will these pushon's withstand water pressure?

Any advise appreciated?

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
