Introduction

Are you

Planning to knock down a load-bearing wall to create an open plan space?

If you have just bought a property or perhaps you have been in it for a while and are looking to renovate, removing a wall can be a game changer to any house if done properly but where do you start??

Who should you speak to first? & How much does it cost to remove a structural wall?

There is conflicting advice on how to proceed with this, for example, the ‘just knock it down and worry about it later’ route (Dangerous) or the ‘It doesn’t look like it’s a load-bearing wall’ route.

The thought of wall demolition or removing load-bearing walls might fill you with dread, but it could transform your house and change the way that you live your life!

Undertaking a seemingly straightforward project is always more reassuring when you understand the necessary steps involved. Unfortunately, many individuals choose to proceed with unauthorized work, only to face significant repercussions down the line. For instance, this can lead to unexpected delays or, in more severe cases, even cause a house sale to collapse entirely! Such outcomes can be highly inconvenient, to say the least.

It’s important to emphasize that the risks simply outweigh any potential benefits.

Proceeding without the proper permissions is just not worth it. In fact, it is vital to recognize the gravity of demolishing an internal load-bearing wall without following the correct procedure.

The potential consequences of removing a support wall are truly catastrophic, as it could jeopardize the structural integrity of your home, putting it at risk of collapsing. Clearly, this is a situation to be avoided at all costs. Safety should always be the top priority, and adhering to the proper procedures is an essential part of maintaining the stability and well-being of your home.

2. What factors affect the cost of removing or demolishing a load-bearing wall?

Some of the factors that can affect the wall removal cost include:

• Size of the wall: The larger the wall, the more expensive it may be to remove.

Larger walls typically have a greater structural impact on the overall stability of the building. Removing a larger load-bearing wall requires more extensive structural modifications, such as installing beams, columns, or alternative support systems to ensure the integrity of the structure. These additional structural elements increase the complexity of the project and can contribute to higher costs.

Removing a larger wall may require more materials, such as steel beams or supports, to replace the load-bearing function. The cost of these materials, along with the labor involved in their installation, can contribute to higher overall expenses.

Removing a larger wall may involve more extensive site preparation, including the relocation or protection of utilities such as pipes in the wall.

Finishes and Restoration: Depending on the size of the wall being removed, there may be a need for additional finishing work, such as repairing or replacing flooring, walls, or ceilings in the affected area and the removal, and reinstatement of existing finishes such as decorative cornice.

The extent of these finishing and restoration tasks can impact the overall cost of the project.

• Type of construction: Removing a masonry load-bearing wall will typically be more expensive than removing a load-bearing stud wall or partition wall.

The type of construction, whether timber or masonry, can impact the cost of knocking down an internal wall due to differences in structural characteristics and the techniques required for their removal.

In the case of a timber-framed wall, the process of removing a load-bearing wall is generally less complex and may involve cutting and reinforcing the timber frame with additional supports or beams. This can result in relatively lower costs compared to masonry walls.

On the other hand, masonry walls, such as those made of brick or concrete, tend to be more substantial and may require more extensive structural modifications. Removing a load-bearing masonry wall often involves carefully demolishing and redistributing the load to other supporting elements, such as installing an RSJ, columns, or beams, which can increase the complexity and cost of the project.

Additionally, the specific construction techniques, materials, and tools needed for removing a load-bearing wall can differ between timber and masonry structures, which can further influence the cost.

 

• Location of the property: The cost of labor and materials can vary greatly depending on the location of the property.

The location of a property can influence the cost to remove a load-bearing internal wall or external wall due to various factors associated with accessibility and labor costs.

Accessibility: If the property is located in a remote or challenging-to-access area, (such as a top-floor tenement flat), transporting equipment, materials, and labor to the site can be more difficult and time-consuming. This can increase the overall project cost.

Labor Costs & Local Market Conditions: The cost of labor can vary depending on the location. Areas with higher living expenses or where skilled labor is in high demand may have higher labor rates which can impact the cost of removing load bearing walls.

This can lead to fluctuations in material costs, subcontractor availability, and overall project expenses.

 

• Level of difficulty: The difficulty of the project can also affect the cost, for example, if the wall is located in a tight space, or if it needs to be removed in stages to support the structure.

The level of difficulty involved in load-bearing wall removal can impact the price due to several factors:

Structural Complexity: Walls that are structurally significant or part of a complex load-bearing system may require more intricate engineering solutions and modifications. This complexity often involves the use of specialized techniques or materials, which can increase the overall cost.

Time and Labor Intensity: Removing a load-bearing wall that is challenging to access or located in a confined space can require more time and labor-intensive work. This can involve careful dismantling, shoring, or temporary bracing to ensure the stability of the structure during the process. The increased labor and time requirements can result in higher costs.

Additional Precautions and Safety Measures: Certain load-bearing walls may have specific considerations due to their location or surrounding structures. For example, walls in proximity to utility lines, plumbing, or electrical systems may require additional precautions and coordination with other trades. Implementing safety measures and coordinating work can add to the overall cost.

Structural Reinforcements: load bearing wall removal will involve the installation of alternative support structures, such as beams, columns, or footings, to redistribute the load and maintain the integrity of the building. The complexity and extent of these reinforcements can impact the cost of the project.

Site-specific Challenges: Each project is unique, and certain site-specific challenges, such as uneven terrain, existing obstacles, or limited access, can affect the difficulty level and, consequently, the overall cost of removing a load-bearing wall.

 

It’s important to note that It is highly recommended to consult with a professional structural engineer to determine if the wall is load bearing and if it is, the type of support that will be necessary after the wall is removed. They can also provide a more accurate cost estimate for the project.

It would be a good idea to get several quotes from different builders to compare the prices and make sure you’re getting a fair price for the work you need. It is also important to remember that the cheapest isn’t always the best, so make sure you are comfortable with the builder’s experience, qualifications, and insurance.

 

3. What are the Reasons to remove a load-bearing or Structural wall

There are several reasons why you might want to remove a load-bearing wall:

1. Open-plan living: Removing a load-bearing wall can create an open-plan living space, which can make a home feel more spacious and open.
2. Renovation or remodeling: Removing a load-bearing wall can allow for more natural light to enter a room or to create a more open floor plan for a kitchen, living room, or dining room.
3. Increase property value: Removing a load-bearing wall can increase the value of a property by creating a more desirable and functional living space.
4. Accessibility: In some cases, removing a load-bearing wall can make it easier for people with disabilities to move around the house, or to install wheelchair ramps.
5. Structural issues: Removing a load-bearing wall can be necessary to address structural issues, such as to repair or replace rotting beams or to correct a settling foundation.

It’s important to note that removing a load-bearing wall is a complex task that requires the expertise of a professional structural engineer and a qualified builder. They will be able to determine if the wall is load-bearing and how to support the structure properly after the wall is removed.

It’s also important to obtain all the necessary permits and approvals from the local authorities before removing the wall, and to ensure that all work is done in compliance with the building codes and regulations.

The way we live our lives has changed, we have moved away from living in lots of different little rooms to living in a much more social environment….big open spaces with lots of natural light, great for entertaining or just hanging out with family or friends

There is no doubt that removing a wall or two can have a dramatic impact on a flat or a house, a large kitchen/diner is on most people’s wish list, it might be on yours!

We at John Webster Architecture have been involved in many of these types of projects and have found them to work particularly well in traditional Edinburgh tenements where the space can be reworked to add value.

4. What types of properties are suitable for knocking a wall down?

Most types of properties are suitable for knocking down a wall, depending on the specific circumstances and structural considerations. Here are some common property types where wall removal can be feasible:

1. Houses: Detached or semi-detached homes often have more flexibility for internal wall removal, as they typically have fewer structural constraints and more open floor plans.
2. Apartments and Flats: The feasibility of load-bearing internal wall removal can vary. It depends on the building’s construction, the presence of load-bearing walls, and sometimes alterations that have previously been made to flats above or below. Removing and altering walls in Edinburgh Tenements are a prime example of this if you consider how many flats within these tenements are in their original state….not many!
3. Townhouses: Similar to houses, townhouses can often accommodate wall removal, but it’s essential to consider the structural implications and any necessary reinforcements before removing walls.
4. Older Homes with Non-Load-Bearing Walls: Older homes constructed with non-load-bearing walls may have more flexibility for removal or alteration, as these walls primarily serve as room dividers and do not carry structural loads

5. The process of removing a structural wall in 3 simple steps

Step 1. Hire a Professional

There is a tried and tested process to follow to make sure that the work is carried out lawfully and that the appropriate paperwork and permissions are in place.

At John Webster Architecture we have carried out these types of projects dozens of times and have developed a slick system to get this done quickly and efficiently.

Very rarely will this type of work require planning permission, unless it is a listed building.

If it is a listed building then listed building consent will be required.

Most people will have an idea of what they want before the wall is removed, if so the next step is to establish if what they want is feasible, at that point, it would be advisable to appoint a construction professional, perhaps an Architect or an Architectural Designer.

We can help you with this.

Speak to us about removing your wall

We will act as your agent guiding you through the process until the building warrant is granted, they will do all the form filling, so you don’t have to!

Upon appointment, we will arrange to visit your property, to come and inspect the wall and discuss your ideas. **Note: it may be that the wall removal is part of a greater project, for example moving a kitchen or bathroom, all of which will come under the works and therefore be ‘warrantable’

We will carry out a measured survey and take photographs to allow him to develop the initial concept into scaled drawings.

Whether the wall is load-bearing or not it will still require the input of a Structural Engineer.

Why is this?

It’s because the Local Authority will insist that a suitably qualified Structural Engineer will be required to confirm if the wall is structural or non-structural.

IMPORTANT

If the Wall is Load bearing the Engineer will provide a suitable structural design along with an SER certificate.

If the wall is non-load bearing the Engineer will provide a letter or report to confirm that the wall is non-load bearing and the removal will not have a detrimental effect on the structural integrity of the property.

The Structural Engineer will arrange a convenient time to visit your property and inspect the wall to tell you whether the wall is load-bearing. He is qualified to identify a load bearing wall & make a definitive call as to whether a wall is structural. this will usually involve some sort of intrusive investigation, it might be removing plasterboard at the top of the wall, having a look within the attic space, and if it’s possible having a look under the floor.

**Note: All demolition work in flats requires a structural engineer’s input.

It’s important to state that the type of wall be it timber stud or Masonry will not in itself tell you if the wall is load-bearing or not.

The Structural engineer will be able to tell whether or not a wall is load-bearing.

Step 2. Get the Building Warrant

A Building warrant is required if you want to knock down a load bearing wall.

If the wall is load-bearing the Structural engineer will produce a suitable structural design to suit the new design scheme.

To have the building warrant approved the Structural Engineer will overmark the architect’s drawings and produce their structural design drawings and an SER certificate which is required for a Building Warrant.

The Architect will then collate all the relevant information, ensuring full compliance with up-to-date building regulations, and produce the final drawings to make a building warrant submission.

It’s important to understand timescales, give yourself plenty of time to apply for a warrant!

In 2023 a project like this will typically take 3 to 4 months from start to finish, depending on the complexity.

If it’s super simple it may be possible to get it through a lot quicker, but it’s important to stress that it’s down (mainly) to local authority turnaround times.

Find out Here how to apply for a Building Warrant…be warned its a bit wordy:)

Once the Building warrant has been granted and the work carried out in a satisfactory manner, an application can be made for a completion certificate, again this is a legal document and should be filed with the deeds to the property.

Step 3. Knock the Wall Down!

The Engineer’s and Architect’s drawings & notes will contain detailed information about what measures need to be taken before, during, and after the wall is removed.

Removing a load-bearing wall is a complex and potentially dangerous task that requires the expertise of a professional structural engineer and a qualified builder. It’s not recommended for a DIYer to remove a load-bearing wall due to several reasons:

1. Safety: taking out the wall can be dangerous and can put the safety of the occupants of the house and the workers at risk. A professional builder will have the knowledge and experience to safely remove the wall and to ensure the stability of the structure during and after the removal.
2. Structural integrity: A load-bearing wall provides structural support for the house. Removing it without proper planning and support can cause the house to collapse, or cause other structural problems. A structural engineer will be able to determine if the wall is load-bearing and how to support the structure properly after the wall is removed.
3. Building codes and regulations: Building codes and regulations vary from place to place, and a professional builder will be familiar with the local codes and regulations and will ensure that the work is done in compliance with them.
4. Insurance: Most insurance policies will not cover damages caused by work that has not been done by a professional builder.
5. Cost: Removing a load-bearing wall can be expensive, but it’s also important to consider that if the job is not done correctly, it can lead to expensive repairs, or even worse, an unsafe living environment.

it is possible for a competent DIY-er, but it’s much preferable to leave this type of work to experienced professionals.

They will have carried out this type of work many times before and have the equipment and know-how to get this done.

It’s advisable to check your insurance coverage, both your own buildings insurance and the contractor’s insurance.
