What Is Lath & Plaster And Why Is It Still Relevant Today?
Lath and plaster is a traditional method of wall and ceiling construction. Here’s a look at what it involves, and what to consider when renovating such plaster.
Lath and plaster is a traditional method of wall and ceiling construction, and many examples can still be found in historic buildings across the UK today. Here’s a look at what it involves, and why it’s important to consider carefully how to proceed if you have a property with lath and plaster walls.
What exactly is lath & plaster?
Before the introduction of modern plasterboard techniques involving drywall, most walls and ceilings in British homes were made with lath and plaster. This involves nailing thin narrow strips of wood called laths across timber wall studs or ceiling joists. Plaster made from a mixture of lime and animal hair was then applied in multiple coats to cover the laths.
This created a breathable surface that was strong and durable, and also lent itself well to moulding and creating perfect smooth finishes. If you live in a Georgian, Victorian, or Edwardian property with authentic cornicing or ceiling roses, then it’s likely to contain traditional lath and plaster.
This traditional plaster has other advantages, including good soundproofing (an important consideration in a terraced house) and it also helps to slow the spread of fires.
Why did it fall out of use?
Despite the advantages of lath and plaster, it was gradually replaced with plasterboard during the 1930s and 40s. The mass-produced drywall was quicker, easier and cheaper to manufacture and install. Lath and plaster is a skilled craft, whereas installing plasterboard doesn’t take a lot of time or training to do.
Why lath & plaster still matters
If you are renovating a property, ripping out old lath and plaster walls might seem to be the obvious course of action. However, it’s not quite as straightforward as that. The first point to consider is that if it’s a listed building, you will need consent from the local planning authority before carrying out repairs or replacements.
It’s an offence to alter or demolish a listing building without consent, and it could result in significant legal penalties. The second point to consider is that even if permission is granted to make the changes, tearing out old plasterwork could affect the breathability of the building and lead to issues with damp and mould.
Can lath & plaster be repaired?
If the basic structure of the wall or ceiling is sound and cracking or sagging is limited to localised areas, it may be possible to repair the lath and plaster. However, this is a skilled technique, and you should consult professionals who have established expertise in this area.
If any sections are beyond repair, they may be able to replicate the original construction methods or combine them with modern techniques for a high quality and sympathetic restoration.
How Interior Designers Can Use Plasterwork In Modern Homes
Decorative cornicing and other ornate plasterwork details are being included by designers looking to blend past and present. Here’s a look at how it’s done.
Recent interior design trends have been all about clean lines and open-plan living spaces, but happily we are now seeing a renewed appreciation of elegant period features. In particular, decorative cornicing and other ornate plasterwork details are now being included by designers looking to blend the past and present.
The role of plaster in modern design
Authentic plasterwork that has been handcrafted with traditional methods is part of the character of older buildings, and provides definition and polish to a room. Wherever possible, designers should seek to preserve original plasterwork with the help of restoration experts. (this may be a legal requirement if it’s a listed building).
However, it’s not just a case of nostalgia for past eras: in the hands of a skillful interior designer, period plasterwork can complement modern aesthetics by bringing a layer of sophistication and interest to minimalist spaces.
Enhancing the flow of a space
Plaster details can enhance the visual flow between different spaces, softening the transition around doorways, ceilings, and light fittings, and adding structure to open plan spaces. For example, panel mouldings in hallways can lead into a room with cornice detailing and a ceiling rose above a pendant light.
Scale and proportion
The most visually pleasing plasterwork looks naturally integrated within a building, rather than imposed as an afterthought. The key here is to choose a scale and design of moulding that is in proportion to the room.
For example, a smaller room might benefit from a simpler Edwardian coving with a subtle curve, whereas a large high-ceilinged space can carry off larger and more elaborate Victorian style plasterwork.
These features can create a space that feels well crafted and authentic, yet has a timeless appeal.
4 Questions To Ask When Commissioning Plaster Restoration
It's important to make an informed decision when it comes to restoring plasterwork features. Here are some top questions to ask a plaster restoration company.
If you are renovating a period property such as a Victorian terrace, a Georgian townhouse, or a country manor, it’s important to make an informed decision when it comes to restoring or replacing any plasterwork features. Here are some top questions to ask a plaster restoration company before you hire them.
What is your policy on restoration Vs replacement?
Some companies might advertise themselves as plasterwork experts, but this does not mean they have special expertise in restoration. THis could lead to the unnecessary destruction of salvageable heritage plasterwork and replacement with modern replicas; a process that is quicker and possibly cheaper.
However, true experts will make a careful assessment of the condition of the existing plaster, and will preserve as much of the features and materials as possible. This will mean that your property retains its original characteristics, which may be a legal obligation if it’s a listed building.
What experience do you have with properties from this era?
Plasterwork styles vary considerably throughout the ages, from highly intricate Gothic and Georgian styles to more subtle Edwardian styles. The materials and methods used to work with the plaster also vary, so it’s important to ensure that the restorer is familiar with properties that are similar in age and style to your own.
Can you create bespoke moulding if necessary?
It might be the case that the original plasterwork is damaged beyond repair, or missing in sections. A competent plaster restorer should be able to make custom moulds if necessary to ensure that the replacements provide visual continuity, with no awkward mismatches of scale, colour or style.
Ask for examples of previous work
Finally, ask to see examples of previous projects with before and after photos, and ask for references from their past clients.
How Can You Restore Listed Buildings After Unlawful Works?
The listed building restoration of a mansion in north-west London following a series of fake old changes highlights the importance of real historical character.
Many of the laws surrounding listed building alterations and restorations were instituted following several disastrous ahistorical changes to British heritage and the spirit of why listed building consent matters was echoed in the recent case of The Rookery in Stanmore.
A Georgian-era mansion with accompanying stables, The Rookery is Grade II listed and according to its official listing dates back to the early 18th century as a home for the owner of the nearby Clutterbuck Brewery.
However, following its purchase in 2022, the building was subject to several changes that left the building “gutted”, with many of its original features removed and replaced with decorations and features described as “fake old”.
Planning and consent have been given to reverse these changes, despite fears that the building might have been so damaged by the unlawful works that it would become impossible to restore before they were stopped thanks to a concerted effort by local conservation groups and enforcement action.
Such was the scale of the illegal alterations that enforcement action was not initially served, although the potential for an unlimited fine and up to two years in prison is still an option under the current law.
It is reminiscent somewhat of the cultural destruction caused by the demolition of English country houses from the late 19th century up until the 1950s when a country house that would now be considered of cultural, historical or architectural importance would be demolished every five days.
Other threats included historic buildings that were bought by wealthy landowners in the United States to be shipped in their entirety brick by brick to another country. The specific threat to Tattershall Castle in Lincolnshire would prove to be a catalyst for greater protection of listed buildings.
Whilst the motivations for these early 20th-century demolitions are different to the faux-historical works made to The Rookery, the result is similar and the extensive restoration work will be looked upon with particular interest by everyone in the conservation community.
How To Care For A Restored Heritage Plasterwork Feature
It’s important to care for the restored plasterwork features carefully to ensure that they remain in good condition. Here are some basic points to bear in mind.
Investing in expert plaster restoration can preserve heritage features such as ceiling roses, cornices, or panel moulding. Professionally restored plasterwork helps to maintain the original character of the building, and ensure that its uniqueness will be preserved for generations to come. It may also be a necessity if you have a listed building.
However, it’s important to care for the restored features carefully to ensure that they remain in good condition for the long term. This is not complicated, but there are some points to bear in mind.
Control moisture and humidity levels
Plaster is a porous material; in fact, water ingress is one of the most common issues that traditional plaster restorers see. Moisture can lead to staining or cracking, or even cause the plaster to break up and fall away. If your home is damp, consider using dehumidifiers, and ensure there is good ventilation throughout the building.
Be vigilant for signs of leaks from pipes or ceilings, or poorly sealed windows or doors. Repair any damage immediately.
Protect against heavy vibrations
Vibrations from power tools, construction work, or slamming doors can cause cracks in delicate plasterwork. Close doors gently or invest in soft-close mechanisms, and avoid drilling or using other power tools near to the plaster.
If there is an unavoidable disturbance, such as a nearby construction site or constant heavy traffic, consider applying a protective coating to the plasterwork or seek a professional opinion.
Clean gently and the keep surfaces dry
To keep the plaster looking its best, dust lightly with a soft cloth, but do not use water or cleaning fluids. Do not scrub or scour, even if the surface is stained. Instead, seek specialist advice in how to restore the original colour.
How To Choose The Right Style Of Cornicing For Your Home
Decorative cornicing is a classic way to add character to a room. With so many designs to choose from, it can be difficult to know which style is right for you.
Decorative cornicing is a classic way to add character and definition to a room. It is traditionally associated with period properties, but it’s also making a comeback for modern homes as well. However, with so many designs to choose from, it can be difficult to know which style is right for you. Here are some useful tips.
What is the architectural style of your home?
It’s not strictly necessary to match the style of the cornicing to the architectural period of your property (unless you live in a listed building, in which case you should consult your local planning authority before making any changes). However, by aligning the style and era of the home and the cornicing, you will help to enhance and preserve its original character.
Georgian era (1714–1837) cornicing favours floral motifs and egg and dart patterns (a repetition of oval shapes and a dart-shaped serrated leaf), often with bold and symmetrical designs. Victorian (1837–1901) style cornicing tends to be more elaborate, featuring nature-inspired motifs and scrolls, and highly intricate classical details.
Edwardian (1901–1910) styles saw a return to simpler and more delicate patterns. The Art Deco era (1920s–1930s) updated this look with bold geometric patterns and stepped profiles. Modern styles of corning or coving tend to feature clean sleek profiles with slight curves or linear patterns.
What is the size and height of the room?
The cornicing size and style should work in harmony with the proportions of the room, regardless of the era it was built. High ceilings work well with larger and more ornate mouldings, while standard or low ceilings suit more subtle and understated designs better.
Coordinating with other plasterwork
If you have existing plasterwork such as ceiling roses, dado rails, or panel mouldings, choose a cornicing that will complement these features to create a cohesive and polished look.
How Is Decorative Plasterwork Used In Contemporary Homes?
Contemporary cornice mouldings and other plaster features are increasingly a popular choice for modern interiors. Here’s a look at some of the potential uses.
Decorative plaster mouldings are often associated with historic buildings, and indeed it’s possible to find some beautiful and well-preserved examples, particularly in listed buildings. However, contemporary cornice mouldings and other plasterwork features are increasingly a popular choice for modern interiors. Here’s a look at some of the potential uses.
What is the purpose of decorative plasterwork?
Decorative plasterwork such as ceiling roses, cornicing, and corbels are used to add depth, character and texture to rooms and hallways. Some of these features once served an architectural or practical purpose, such as corbels that were used for supporting shelves and mantlepieces, and ceiling roses that were used to protect the ceiling from soot marks.
However, over time the features have evolved into a way of drawing a room together to create a pleasing sense of harmony, and to add interest with touches of detail.
Sleek modern cornices
Cornices are used to soften the transition between the wall and the ceiling, and traditionally they were also ornate features with detailed leaf scrolling or floral designs. Contemporary cornice designs take a more subtle approach, creating clean lines to add an elegant framing to the room without being overwhelming.
Cornicing works particularly well in spaces with high ceilings, to add simple curves or lines and create a more finished look to the room.
Contemporary ceiling roses
Ceiling roses of the Georgian and Victorian style tended to be highly elaborate affairs with a combination of flowing curved shapes and floral or animal motifs. Modern interpretations favour geometric patterns, and are used to pair with statement pendant lighting to create a focal point.
This feature works particularly well in larger spaces with high ceilings. For rooms with lower ceilings, opt for a smaller and more understated design.
Decorative panel moulding to add interest
Panel mouldings were once the preferred choice for drawing rooms in large houses, and are particularly associated with Georgian properties. However, they are being repurposed to add depth and texture to contemporary homes, particularly those with large open-plan spaces.
The panels help to break up large areas of plain walls, and can be used as the basis for a feature wall. For a more subtle and understated effect, paint the walls and mouldings the same colour and let the lines do the talking.
Ornate plaster corbels
As we mentioned before, corbels can serve a practical purpose, to provide extra structural support. However, they are also an aesthetically pleasing feature and can be used to create a more polished and symmetrical appearance to counterops, mantles, or shelving. Modern corbels are often painted in a bold contrasting colour scheme to draw the eye.
So, there you have it: these are just a few examples of the way in which decorative plasterwork is incorporated in modern interior design. It is a timeless feature that can be combined with contemporary styles to bring an extra dimension to modern homes.
Why The Plaster Ceiling Rose Is Experiencing A Renaissance
The plaster ceiling rose has come full circle to become a popular feature in contemporary interior design. Here’s a look at the reason behind this reflowering.
The plaster ceiling rose has come full circle from being a functional item to a decorative feature that fell out of fashion by the mid-twentieth century, to a popular element of contemporary interior design. Here’s a look at the reason behind this rosy reflowering.
The historical purpose of the ceiling rose
Originally, ceiling roses were not installed for decorative purposes, but to protect the white ceiling from sooty marks from candles or gas lighting. The dirt could then just be wiped away from the circular plaster moulding, rather than a wider area of the ceiling. However, they only tended to be found in the most well-off homes.
The grandest buildings often had very ornate ceiling roses with elaborate designs featuring flowers, leaves, shells or other natural motifs, combined with flowing shapes and embellished borders. By the Victorian era, ceiling roses were a standard feature in more ordinary homes, perhaps with simpler designs.
The resurgence of the ceiling rose
Enhancing original features
Today, ceiling roses are enjoying a revival thanks to their ability to enhance the charm of original features in highly sought after period homes. They can help to maintain the character of a property, adding a touch of authenticity and elegance to the interior.
Combining classical and contemporary
Modern interpretations of ceiling roses are now a fashionable choice for contemporary homes. They are perfect to pair with statement lighting such as chandeliers or sculptural pendant lights, and sleek designs can add a touch of timeless elegance to any style of home.
Durability and sustainability
Decorative plasterwork is crafted from sustainable materials that are also highly durable, making it an ideal choice for homeowners who are looking to combine their ethical values with high quality interior design.
