Bricklaying Question

Creating a lightwell next to the pavement

We want to open the existing lightwell up so that it lets a lot more light in. The proposed light well would be 4m across by 1m width, and 1.8m deep. This would bring it up against the front wall separating our house from the pavement.

Are there any structural considerations for this job?
Do highways need to be notified?

I can't seem to find this information available anywhere else on the web!

thanks
Mark

Hello, Firstly I have to inform you that Planning Permission is required for this, so talk to your planning office first, I would suggest they are unlikely to grant as they don't normally let you build towards a roadway but if there is an existing light-well you never know. Next, If the light-well is shallow it may be possible to climb out of and thus be classed as a fire escape from basement level(something to consider).There are definitely Structural considerations/Limitations The Loads from any structure spread out at between 45 and 60 degrees from it's lowest point(basically) so if you want to reduce to 1.8m deep you will need to be 1.8m from the roadway or you will be undermining the road, The council will definitely require Structural Engineers calculations for how you are proposing to hold up this weight (approx. 1 Tonne per 0.6m3 + whatever is on the road) You will have to hold up all this weight on your own property so you are unlikely to be able to do this within the same dimensions as the existing boundary wall(which only holds itself) There will be services in the footpath to avoid,and probably pedestrian closure while the works take place,services also come into your property, not normally in the same location, and as pre-meter will have to be relocated by the various providers(costly). I am sorry to be the bearer of bad tidings, but it is best to know what you are getting involved with.
Best of Luck!
