BISF House of My Dreams in Braintree Essex
Hello, I'm currently buying a BISF house in Braintree, Essex.
It's my first house and I want to do a huge renovation.
I have read through the entire forum and It's amazing.
The first time I heard about BISF houses was from my Estate Agent, when I had my first viewing.
At first I was scared but now, after read this forum, I'm really happy that I bought it.
I've just finished building school and I've been working for 7 years in UK in maintenance, 2 years ago I also got my electrician qualifications. I have a lot of experience with refurbishment, decorating, plumbing and electrics, but I don't have any experience with BISF houses.
I Know that it's only the construction type that is different, but it's also the most important part of house.
I haven't bought the house yet, but I want to be prepared for everything before I have the keys in my hand. After this I will just get on and DO IT!
I hope that all professionals and BISF house owners will help me.
I can promise share on this forum with my all new experience acquired during the renovation.
My first idea:
I read somewhere that in BISF houses I can take out all of the internal walls.
For me it's possible because all weight from upstairs take huge steel floor beams.
Can anyone confirm this?
With external walls I want just make additional doors for toilet and doors from existing kitchen to existing toilet make wider about 60cm.
I worry a little about the water heater tank between bedrooms 1 and 2. If need I to, can I move it or remove it and buy a combi boiler?
I will remove fire and chimney.
I will put some images to help you understand my idea.
Thanks for any help
Hi Grangey, that's a great photo! I haven't seen a picture like that of the frame revealed in the kitchen (or corners of the house in general). So far I've only revealed the steel frame in the living room and back bedroom, where there are no diagonal braces. What is that wooden band above the door though? I did not find anything like that in the living room.
Also, I've been thinking it would be a good idea to remove and replace the steel reveals round the inside of both exterior doors as they are horrible cold bridges (they get covered in condensation) but I wasn't sure if they are removable from the rest of the steel door surround, so I was wondering if you could tell as you've stripped off the wall lining around it.
BTW I thought I'd replied thanking you for your floor beam measurements, but the post seems to have disappeared!
I was thinking that there is only one stanchion and one roof truss near the centre of the pair of houses as it wouldn't make sense to have two right next to each other on either side of the party wall and only one seems to be visible in the photos of prototype houses under construction.
I guess the party wall could take some weight but given it wasn't intended to, I don't think it would be wise to rely on it, as it wouldn't have been built with load-bearing foundations.
Actually, I think if your heart is set on a completely open plan house downstairs, a BISF house is probably one of the best places to start as it is much more lightweight than a traditional house and does not need as much support. It would still be a very big job and personally I wouldn't recommend it. However, I have seen more challenging projects such as a house with a concrete first floor made open plan using a system of no fewer than four interconnected box-section steel supports.
Ed, you sir are making me reveal far too many pictures of my renovation before I am ready to 😛 but funnily enough I did just that only 2 weeks ago;
Yes the inner door surrounds are removable, however without the walls stripped either side (and even with them out) its no easy task. They are bolted in all the way around, 4 on each vertical, 2 at each side at the top joining the horizontal and the vertical, and then 2 adjoining the vertical. The front door came far easier than the rear, as the nuts were on the inside, however the back door was near increadible touch as the bolts were inside and sized on, so I used an angle grider and drill, and by creating 2 cuts on each section at the top and bottom (and on the top part each side) and gradually drilling out the top screw hole large enough to literally rip the frame away from the top, the rest tore off pretty easily afterwards- bar the top, which still needed alot of man handling.
I will warn that this did damage the innter frame of the door very slighly (as you would expect bending things around) but only visually and I dont exect it to cause any issues when boxing it back in.
As for the wooden beam, this is what the flashing from the original asbestos roof for the outhouse adjoined to- you can just see where the copper flashing is pinned over it to the inside.
As you can tell, I've literally gutted this place and rebuilt it from scratch (completely on my own I might add) whilst living in it (..which is a fun experience) and I've taken at the moment about 450 pictures throughout the project, so chances are I have a picture of anything youre uncertain of so if theres anything you'd like to know do feel free to ask!
Thanks Grangey! Sorry for making you reveal things prematurely! Your picture shows just what I was expecting, that the reveal could be removed from the outer part (ie leaving the frame round the outside of the door embedded in the render). I'll only remove it when renovating the kitchen which won't be soon as I work full time so finding time is difficult, but thought I'd ask while you had the kitchen gutted. Next on the list is the bathroom so I'll have to deal with diagonal braces like those in the kitchen.
Strangely enough none of the BISF houses in Bath have typical lean-to outhouses and instead have an outhouse with a flat concrete roof so probably there will not be that wooden beam here.
Oh trust me from an insulation perspective those diagonal braces are a royal PAIN, my work around them has been far from ideal but as I have the secondary layer which helps remove thermal bridging Im happy enough that this should help pick up any deficiencies my appauling cutting skills have left behind! Funnily enough the bathroom is the only room I haven't yet (but Ive done the 3rd bedroom which is of course identical just mirrored) done as Im waiting to start and finish the new downstairs shower room first so I can naturally always have a working bathroom.
The wooden beam sits directly on top of the concrete walls (which in my case are not concrete blocks, but actually nothing more than a metal mesh skimmed both sides with concrete) and is just below the bottom of the steel cladding, so probably wouldnt even be visible looking down from upstairs as you have the steel cross brace the cladding attaches to blocking the view. Depending on the height of the concrete roof though and particularly the flashing, I wouldnt be all that surprised to find something similar in place on yours so it will be interesting to see what you discover. Good luck with it
I was expecting the braces to be difficult as they appear to obstruct the void that I had put the main layer of insulation in (70mm of Celotex/Kingspan) in the other rooms, so I'm not really looking forward to that!
The bathroom is next as while all the rooms were shabby, the bathroom is actually quite urgent as the grouting has failed (emergency repair with silicone) causing tiles to fall off and water to soak through to the kitchen ceiling.
At last there is another person with a BISF house in Braintree on this message board, most of the houses are still council owned so they would not bother on this forum. I brought this as my first house 9 years ago now. I am on Rosemary Avenue near St. Francis school so you must be close on Coldnailhurst or Deanery Hill/Gardens. You really have grand plans with your house. What have you done so far?
I have completely refurbished my house but did not go the extents of changing the glass fibre insulation. Instead I used a bubble wrap with foil to reflect the heat in with an air gap then plasterboard on top. I don't know how effective this is but it was allot cheaper and easier then filling with expanded foam type of insulation. I completely stripped the old plasterboard and hardboard from the walls and re-built the internal stud walls. I have changed the layout upstairs slightly to make a bigger bathroom, removed the old chimney and made the old airing cupboards into built in wardrobes. Downstairs I still have the hallway and lounge with double doors into the dining room. I blocked the back kitchen door off which makes the kitchen allot bigger and put bi-fold doors where the dining room window was. This opens onto decking and paving but still have to finish the 130 ft garden. Eventually I want to put a conservatory on the back too. I have plans to make the coal shed extension into a utility room with a door into it at the bottom of the stairs. Where I want to put the door there is a diagonal brace which people on this forum think it is al right to remove as other people have done this.
Hello guys. I have just brought a house at Rosemary avenue Braintree.
I need a few tips to do with putting in insolation into the walls.
What method is the most effective? And can someone recommend a company that would do this?
I would also like to change the windows and do central heating. Thanks in advance.
