Does having a chimney stack in my loft matter?

Having a chimney stack in the loft is very common in most properties built before 1960 and this will cause no problem or additional expense while converting the loft.  If the chimney stack is not in use and no longer required it is often advisable to remove the chimney to avoid unnecessary maintenance at a…

We have a loft single bedroom approx 10’x10′ built at least 20 years ago by a previous owner of the house, but we don’t think the floor was strengthened at the time. In order to be able to state when selling the house, that is a usable bedroom, would the floor have to be strengthened? How expensive would this be and would additional timber joists be required or RSJ’s? And also what are the head room minimum requirements?

We would need to survey the property to give an accurate quotation to supply and install a structural  floor at the loft level, as we would need to check if you have internal load baring walls to confirm the size of the beams and joists required. With Reference to the head room, you must have…

I am considering rear and side extension of a semi-detached bungalow together with a loft conversion, but the height of the loft is around 1.9m. Is it possible to raise the roof only on my property? Is this likely to be permitted by the planning authority or not?

1.9m would be very tight to convert, but it does make a difference where the measurements were taken from.  You would need a minimum of 2m from the top of the ceiling joist to the top of the ridge board ( the ridge board is the timber at the very top of the apex of…

The height of my loft is approx 1.5metres. Is this too low for a loft conversion? What are the options?

1.5m from the top of the ceiling joist to the underside of the ridge board is too low to form a loft room.  The minimum measurement would be 2.1m, the only  option available is to raise the ridge and re pitch the roof at a steeper angle.  Obviously this would only be feasible on a…

Can Charles Grosvenor undertake any other work, for example I am also considering a rear extension as well as a loft conversion and i would ideally like to contract the same company to build both projects?

Although we are a loft conversion specialist, we do have the capacity to build extensions and carry out alterations to meet the clients requirements, is it often makes sense to have one contractor responsible for the entire project to avoid confusion and eliminate grey areas within the works. We are able to offer viewing addresses…

Is the work and all trades men on site supervised throughout the loft conversion?

Should you decide to go ahead with a Charles Grosvenor loft conversion, the loft conversion team would always have a foreman in charge of the day to day works. You would always be appointed a project manager who would inspect the works on a weekly basis and update you accordingly. These weekly inspections are in…

I live in a Semi-detached house, are there any neighbourly considerations that I need to be aware of if I want to have a loft conversion?

Apart from the obvious ones like the additional contractors vehicles, scaffolding being erected and noise from hammering and sawing etc.  A home owner must comply with the Party Wall Act 1996, and obtain the adjoining owner’s permission to use the shared party wall.  If the adjoining owner does not give their consent to use the…

Question from Mr Garvey

My neighbour in north london is about to build a loft conversion with the dormer cheeks flashed over the party wall and cut-outs from the party wall for loadbearing purposes.  They say they dont need planning permission for this even though the previous owner build a back extension etc.  I am concerned as i havent…
