Dear @judibutler I assume you are referring to a wall which is wholly above ground and that you have completely ruled out damp tracking into the wall from above. A lot depends on the size and thickness of the wall and other factors, such as if the building is listed. Damp penetration (driving rain) through granite walls has been an ongoing problem in church towers in the southwest of England for some time. Ironically the problem often seems to get worse after re-pointing in lime. Granite is fairly impervious and was often in laid in large blocks meaning trapped water has little chance of getting out through thin mortar joints. Historic England held an excellent conference on the subject in 2013; the transcript of proceedings can be found at: http://content.historicengland.org.uk/content/docs/research/damp-towers-conf2013-programme-transcripts.pdf A roughcast lime render coat may help, but there could equally be voids in the wall which are holding damp and may need grouting. However, grouting is a very tricky and expensive technique which should not be undertaken lightly, and only works if one knows exactly where the voids are. Over-cladding the whole wall with semi-sacrificial weather boarding may be a last resort. This and rendering are likely to require planning consent. Depending on where you are located, a company like ArchiMetric (www.archimetrics.co.uk) could insert some interstitial moisture monitors into the wall to try and find out exactly where and when the damp is getting in and how it is moving through the wall, but this may be expensive. Some localised investigation by dismantling pockets of stone may be useful. The Society of Ancient Buildings helpline (mornings only on 020 7456 0916) may be able to help with specialists in your area. Most importantly try to get an understanding of how water is getting into and moving through your wall before you embark on anything. If your problems relate to below-ground damp then a different response will be needed.

Moved from a lovely 2 bed flat in Ealing to a 3 bed Victorian mid terrace in Hitchin in North Herts on the train line into Kings Cross/Moorgate in 2011. I struggled to leave the city but our town is v lovely and unique for commuterville in that there is a lots on offer on our high street both for shopping and entertainment. That said, we've sold to move a little closer to a big city again. Moving 10 miles north of Brighton later this year. I love our house and the space but after 5 years I feel I need more than there is on offer here and once we leave this town, it's a 30 minute (usually more) drive minimum to get anywhere with more on offer. I'm a city girl through and through and though I can no longer afford to live in one, I need to be close to one. Space is great, but think of what you do with your spare time, though it's pretty fab for where we are, I feel I outgrew this town of 35,000 people in less than 5 years.

Hi Gus, we are mid side return build currently and had exactly your dilemma last year when we were talking about the work we wanted to do. Ultimately we figured it came down to whether we were willing to pay to avoid the project management & associated stress! So we had a number of ‘design & build’ companies come to visit, talk over and quote for the work, in addition to working out costs of managing the various components separately. After breaking down all the moving parts (architect, structural engineer, party wall surveyor, planning application, builder, plumber, electrician, plasterer, tiler, building control, drainage, tree survey - off the top of my head!) we opted to go with a D&B (project management) company to carry out & coordinate everything for us. Our reasoning included: they have experience, can anticipate things we probably wouldn’t even consider or know about, have access to all the trades, can put a team together which suited our timeline, can coordinate all the trades (and know when to!) at the relevant times, they do it full time (rather than us working at the same time), etc... So in short, it boils down to whether you want to pay for someone to take care of things for you! After we did a number of the elements for our wedding and wishing after the fact we’d just paid to not have to deal with it - we took that on board for this somewhat larger project and went with a D&B company. So far so good.... fingers crossed it remains this way!

Hi Scott087, It looks like your bungalow is a semi-detached, and if so, your extension will fall under Permitted Development as long as it a max. 8m deep from the face of the original existing rear wall. In addition, if your house was built between 1918 and 2018, you could simply add a first floor under Permitted Development unless your house is in a Conservation Area. In any case, although it is good to get some initial ideas on this platform, I would strongly recommend you approach an Architect as there are many factors to be taken into consideration before a scheme is drawn up.. I usually get to see the property, assess any constraints, figure out how the structure works etc. before I come up with a sketch layout, as I am aware there is a lot of work 'behind the scenes' to arrive at the best layout tailored to your needs and based on the existing house / site specific constraints.
