In case you’re renovating a home, there is a truthful probability it is constructed from stone. The British Isles has an abundance of stone properties all over the place, from small flint cottages to massive stately houses and every little thing in between, akin to previous farmhouses and manor homes.
Nonetheless, each proprietor of considered one of these properties, whether or not it’s a house owner or a bigger physique akin to The Nationwide Belief, might be aware of each the wonder and attraction of utilizing stone, and the pitfalls in proudly owning and renovating a stone home.
Step one in understanding how finest to renovate your stone constructing is to establish whether it is an historic constructing – usually constructed pre 1919 with stable wall building and and not using a damp-proof course, or a contemporary constructing – recognized by the inclusion of a cavity wall.
On this article, I take a deeper dive into the historic class that will help you set up the important thing factors it’s worthwhile to think about earlier than renovating a stone home.
Insulation and thermal efficiency: Learn how to obtain the correct quantity
A key consideration in modernising or upgrading an previous stone constructing is deciding what stage of thermal efficiency you are attempting to realize. Though it’s doable to extend the insulation ranges of a stone wall by insulating the within of the wall (this is called dry lining) there are a variety of points to concentrate on.
You will need to preserve the breathability of the construction, so any supplies added to the internal face of the constructing should be breathable in an effort to be sure that condensation doesn’t construct up within the wall building. Typical supplies appropriate for this goal embrace sheep wool insulation and wooden wall board. These supplies usually are not solely breathable, but additionally are sustainable as they’re produced from pure supplies and are biodegradable.
Nonetheless, you will need to take a holistic strategy when bettering the thermal efficiency of a stone constructing. The partitions are just one aspect of the constructing cloth – it is perhaps extra helpful for instance to enhance the insulation ranges of the flooring, roof, home windows earlier than contemplating the partitions.
It is also essential to keep in mind that previous buildings don’t lend themselves to turning into utterly hermetic. A stage of air flow is required and vital to take care of breathability. You will need to establish an applicable stage of efficiency for the constructing and to go for the straightforward wins which are low price and simple to implement, akin to draught proofing home windows and doorways.
Integrating providers when renovating a stone home
Because the thickness of stone partitions can vary from 300-1000mm, integrating providers into stone buildings can typically be a problem. Due to this fact it’s essential to have a transparent design technique in place on the outset and might change relying on in case you are seeking to depart stone partitions uncovered or cowl them with new partitions.
Putting in providers on uncovered stone partitions
If you’re hoping to showcase your stone partitions, one design technique that can be utilized is to reveal the providers so they’re mounted on the floor of the stone. That is fairly an industrial look, however not as simple because it might sound, as if the stone could be very uneven then the fixtures might not sit on the floor tidily. As well as your electrician and plumber should be suitably expert to make sure any pipework and conduit are neatly organized and put in.
Additionally, you will must plan precisely what providers you want and the precise places and specs of sockets, lights, thermostat radiators and plumbing fixtures a lot earlier on within the building schedule, ideally at first repair stage. This may be difficult by way of each design and co-ordination, because it requires further organisation and, after all, comes at a price.
Choices when integrating into new stud partitions
One other technique is to combine the brand new providers into any new stud partitions or areas that might be dry lined. That is simpler to implement than the uncovered providers technique however requires ahead planning by way of design to make sure that you’ve got the suitable distribution of providers within the room.
You’ll need to make sure you have sufficient sockets, sufficient lighting distribution and heating provision. This may show problematic in the event you solely have one new wall as it may be stuffed fairly rapidly, as all of the providers might be competing for a similar space.
Utilizing a mix of recent and uncovered partitions
Nonetheless, the excellent news is you do not have to decide on one strategy all through the property. Each of those methods can be utilized together, and for various areas. If you’re working with a designer or architect they need to be capable of assist information and advise you in order that your remaining selections work with the general design of the constructing.
When chatting with shoppers, I at all times look to focus on key partitions that is perhaps uncovered, focus on what kind of heating is perhaps applicable, and the lighting design being contemplating to make sure all these parts may be built-in. On a number of buildings we now have additionally used a technique the place we now have launched a wainscot element utilizing half top wall panelling to combine providers at a low stage and expose stonework increased up. This not solely seems good however helps to scale back the quantity of uncovered electrical and plumbing.
It is usually doable to complement your service integration through the use of utilizing the ground. For instance, in case you are putting in a brand new flooring slab you is perhaps putting in underfloor heating which can take away the necessity for radiators. It’s also possible to add flooring mounted electrical retailers and lighting in an effort to cut back the requirement for providers within the partitions.
Structural modifications are doable with skilled calculations
Stone buildings are usually fairly forgiving relating to making structural modifications because the load paths are usually fairly easy and stone partitions are usually fairly deep.
Nonetheless, the viability and price of alterations will rely on the person constructing, its situation and the best way it has been constructed. It’s at all times essential to take recommendation from a structural engineer that’s used to working with stone buildings.
The significance of getting your repointing proper
If structural modifications have been made, or exterior openings have been altered, then repointing is perhaps required to reconcile the altered space. It’s wonderful how a lot repointing a home can alter its look – for higher and for worse!
It’s uncommon {that a} home must be totally repointed as most historic pointing is definitely fairly sound, and a whole lot of the time repointing is taken into account as a method to tidy or smarten up the looks of a constructing. Nonetheless, this could at all times be a final resort as typically it may give an ‘over-restored’ look and erode the character of the unique home. Usually there may be not one pointing kind or mortar combine on an older constructing, however a number of kinds and hues that talk of the phases of improvement of the constructing and assist talk its character and historical past.
Historic buildings had been historically pointed utilizing lime, sourced and slaked domestically, and every space has its personal distinctive components and hues. Lime is softer than stone and due to this fact offers a sacrificial layer which weathers out. Within the twentieth century, lime was typically changed with cement which might trigger fairly just a few points in older stone properties because the cement is usually tougher than the stone.
If you’re in an space of limestone, such because the Cotswolds, it is price asking your stonemasons or most important contractor to organize a variety of lime mortar pattern partitions in an effort to present completely different pointing mixes. This may help guarantee you choose the suitable match to the prevailing one.
It is also essential to keep in mind that if the property is listed you’ll need to acquire listed constructing consent for any repointing work that goes past a small patch restore that is perhaps thought of “like for like”. The conservation officer will need particulars of the pointing combine and might also wish to see a pattern panel to approve the color and elegance of pointing.
Retaining and restoring character options
Historic stone buildings are stuffed with character options and one of many challenges may be the way to retain or reveal these options, whereas creating a house that works for contemporary residing. Uncovering an inglenook fire for instance might really feel like an ideal additon to your front room, however you will need to keep in mind that opening up a hearth is a structural enterprise. It’s due to this fact price understanding the worth and complexity of the material of your own home, earlier than deciding what to take away.
As with repointing, if your own home is listed, you’ll need listed constructing consent to work on fireplaces and the conservation officer will need a detailed appraisal of the importance of the characteristic and the phases of improvement, earlier than permitting you to change it.
Even when your own home isn’t listed it may be helpful to try to analyse what has occurred to the fireside as it’s one space of a home that has typically skilled fairly a little bit of change. Fashions and modifications to know-how imply fireplaces have shriveled to be extra environment friendly over time.
In case you resolve that you just want to open up the fireside, its advisable to seek the advice of a structural engineer because the load paths might have modified within the fire over time. Chances are you’ll want structural interventions, such because the insertion of a brand new beam or strengthening of the chimney breast, to make sure the fireside is sound. Opening up these kind of fireplaces is hazardous and may at all times be completed by an skilled contractor. Momentary works akin to props might also be wanted to make sure the construction is sound whereas it is being labored on. It may also be very messy with soot and filth pouring out of the chimney and it’s worthwhile to resolve if it is price including to your renovation schedule or in case your renovation prices are finest spent elsewhere.
After all, with the suitable strategy, design staff and certified tradesmen, it’s completely possible to change and reconfigure stone buildings to make sure they’re match for contemporary residing each by way of their structure and thermal efficiency.
For extra studying on stone buildings, I like to recommend a simple to digest e-book referred to as The Outdated Home Handbook from Amazon which offers a whole lot of sensible recommendation and options to the problems above. As well as, historic England has some very helpful technical info accessible on-line.
Or, in the event you’re nonetheless searching for the suitable property to make your mark on, be sure you comply with the recommendation in shopping for a property to renovate to make sure you do not find yourself buying a home that is hiding too many secrets and techniques.
