Using Cantilevering in Modern Home Designs

Jigsaw • 1 March 2023

What is a cantilever?

A cantilever is a rigid structural element that extends horizontally and is supported at only one end. Typically, it extends from a flat vertical surface such as a wall, to which it must be firmly attached. Like other structural elements, a cantilever can be formed as a beam, plate, truss, or slab.

Building an extension in this way requires a dedicated team of architects or designers, structural engineers, and builders so that the execution is perfect from design to completion.

Rooted in physics and structural design, cantilevered additions are a great way to add more living space to your home and open up the rooms around the outer segments of a floorplan. Below are a few of the benefits that cantilevered additions and remodels have to offer.

Add More Living Space

Cantilevered additions can allow you to completely elongate a space without having to do the same thing to every level of the home. For example, if you wanted to elongate the main room on the second floor of your cottage overlooking the water, a cantilevered addition could be a great fit. Combined with floor-to-ceiling windows, this style of addition would provide gorgeous views.

Create Architectural Interest

Cantilevered additions create a unique architectural interest, both in the interior and exterior of the home. Cantilevered additions are most often associated with modern home design but can work well under a variety of conditions and with a diversity of home styles.

Cantilevered Micro-Addition

A cantilevered micro-addition, or a cantilevered bump-out, allows you to add a little more space to a room without having to undertake foundation work and, therefore, it’s a more cost-effective solution for more living space. A great option if your property hosts mature trees where the roots would otherwise be disturbed if you had to dig an extended foundation.

These bump-outs are prime for creating a new counter/storage space in the kitchen and creating a perfect spot for a wall installation or entertainment unit in the main living room, for example.

Cantilevered kitchen counters, bathtubs and furniture are growing in popularity as homeowners continue looking for ways to personalise a space.

This dramatic kitchen island features a mahogany wood top with a long steel support underneath that is wedged a few feet into the concrete island. It can be used for several purposes, including dining, food preparation, reading or kids’ homework. It’s also a good example of accessible design since a wheelchair can glide right up with no obstacles.

What to consider

Renovation difficulties

Since this style of extension is hanging in mid-air, not all homes will be able to incorporate them into their architecture. The dimensions of your home will dictate the size and shape of your cantilever. Make sure you consider this before drawing up those plans for this project.

Design

How far your design will be able to protrude will depend on construction. There are three main areas your designer will need to consider:

· The load above — how much weight is on top of the supported section of the structure?

· The anchor point — how is the cantilevered structure connected to the other elements of the building?

· The materials you plan to use and their strength.

Having a good structural engineer on your project is essential. Their job will be to make the structural calculations that will allow your builder to create a safe and legal result. These structural details will be checked by building control to make sure your project is compliant with the Building Regulations.

Cost

A cantilever will increase costs in comparison to a 'regular' extension, so calculations on budget must be made before any work begins. As cantilevered structures are more technically ambitious than most other features, you should be prepared to pay a premium if you want to include them in your design. The additional extension cost using a cantilever will include the steel beams, reinforced concrete and other expensive materials required. However, the value added by a good cantilever design can far outweigh the cost in terms of how you use the property and in property sale.

Planning a home extension in Surrey , a loft conversion , or even a new build? One of the biggest early considerations is whether you’ll need planning permission . For many homeowners, the process can seem confusing—but with the right knowledge and an experienced Surrey construction company by your side, it becomes much simpler. At Jigsaw Construction Surrey , we’ve supported countless homeowners through planning applications, helping them move smoothly from paperwork to building work. Here’s our step-by-step guide to navigating planning permission in Surrey. Step 1: Do You Need Planning Permission in Surrey? Not all building projects require formal approval. Some fall under Permitted Development Rights (PDR), which may allow you to extend or convert your home without submitting a full application. However, in Surrey, these rights can be restricted if your property is: Within a conservation area A listed building Situated in the Green Belt 👉 Before starting your project, check with your local Surrey council or ask our team at Jigsaw Construction Surrey for guidance. Step 2: Understand Local Planning Policies Each borough—Guildford, Elmbridge, Woking, Epsom & Ewell, and others—has its own Local Plan, which sets rules for building work. These policies cover: Building scale and height Design and materials Neighbour impact (privacy, light, outlook) Environmental impact Researching these guidelines early gives your project the best chance of success. Step 3: Create Detailed Plans A strong planning application depends on clear, accurate documents. Typically, you’ll need: Architectural drawings (site plans, elevations, floor layouts) A Design & Access Statement explaining how your design fits local policy Supporting reports (e.g., tree surveys, flood risk assessments) At Jigsaw Construction Surrey , we collaborate with skilled architects to make sure every application is thorough and professionally presented. Step 4: Submitting a Planning Application in Surrey Applications are submitted online via the Planning Portal or your local council’s website. Fees vary depending on the type of project. Once submitted, your application enters the consultation stage. Step 5: Neighbours & Community Consultation Neighbours and other stakeholders are invited to comment on your application. Common concerns include: Loss of light or privacy Parking and traffic impact Design compatibility with the local area Tip: Talking to your neighbours in advance can reduce objections and speed up the approval process. Step 6: The Planning Decision Most councils in Surrey aim to decide within: 8 weeks for smaller projects (such as home extensions) 13 weeks for larger developments If approved, you’ll receive a decision notice with any conditions. If refused, you can appeal—or make changes and reapply. Step 7: After Planning Permission – Building Regulations Even if planning permission is granted, you’ll still need to meet Building Regulations . These ensure that your project is structurally sound, energy-efficient, and safe. Our team at Jigsaw Construction Surrey helps clients every step of the way—from planning permission through to Building Regulations approval and construction. Why Choose Jigsaw Construction Surrey?

In the dynamic and complex world of construction, project management plays a pivotal role in the successful delivery of projects. Effective project management ensures that construction projects are completed on time, within budget, and to the expected quality standards. It plays a crucial role in coordinating various moving parts, managing risks, and ultimately satisfying client expectations. This blog will explore the critical importance of project management in construction projects. Ensuring Effective Planning and Organisation One of the primary functions of project management in construction is the development of a detailed project plan. This plan encompasses timelines, resource allocation, budget estimates, and risk management strategies. A well-structured plan serves as a roadmap for the entire project, guiding the construction team through each phase from inception to completion. Project managers are responsible for organising all elements of the project, ensuring that every team member knows their role and responsibilities. This level of organisation is essential in avoiding delays, preventing miscommunication, and maintaining a smooth workflow throughout the project lifecycle. Risk Management and Problem Solving Construction projects are inherently risky due to their complexity and the numerous variables involved. Effective project management involves identifying potential risks early and developing strategies to mitigate them. This proactive approach allows project managers to address issues before they escalate, ensuring that the project remains on track. Moreover, project managers are skilled problem solvers, equipped to handle unforeseen challenges that may arise during construction. Their ability to devise innovative solutions and adapt to changing circumstances is invaluable in maintaining progress and minimising disruptions. Resource Management Efficient resource management is another critical aspect of project management in construction. This includes managing human resources, materials, equipment, and finances. Project managers must ensure that resources are used optimally, reducing waste and avoiding unnecessary costs. By effectively managing resources, project managers help to keep the project within budget and ensure that the necessary materials and labour are available when needed. This level of control is crucial in maintaining the project's financial health and ensuring its timely completion. Quality Control and Assurance Quality is a non-negotiable aspect of any construction project. Project managers play a key role in establishing quality standards and ensuring that these standards are met throughout the construction process. By implementing rigorous quality control measures, project managers can detect and rectify defects early, preventing costly rework and ensuring that the final product meets or exceeds client expectations. Communication and Stakeholder Management Project management is also vital in fostering effective communication among all parties involved in a construction project. This includes clients, architects, engineers, contractors, and suppliers. Open and transparent communication helps to align expectations, build trust, and facilitate collaboration among stakeholders. Furthermore, project managers are responsible for managing stakeholder relationships, ensuring that their needs and concerns are addressed promptly. This aspect of project management is crucial in maintaining a positive working environment and securing stakeholder satisfaction.  Conclusion In conclusion, project management is indispensable in the realm of construction projects. It provides the framework for planning, organising, and controlling all aspects of a project, ensuring its successful completion. By effectively managing risks, resources, quality, communication, and stakeholder relations, project managers play a vital role in delivering construction projects that are on time, within budget, and of the highest quality. As the construction industry continues to evolve, the importance of skilled project management will only continue to grow.

Creating the Perfect Summer Garden: A Harmonious Blend of Landscaping and Construction  Summer is the perfect time to enjoy your outdoor spaces. A well-designed garden can be a tranquil retreat, a vibrant entertainment area, or a combination of both. Achieving the perfect summer garden often involves both landscaping and construction. Understanding how these two disciplines work together can help you create a stunning and functional outdoor space. Landscaping and construction are not mutually exclusive; they're complementary. Construction provides the “structural framework” for your garden, while landscaping adds the “aesthetic and natural elements.” For example, building a retaining wall (construction) can create levelled planting beds (landscaping). Similarly, installing a patio (construction) provides a foundation for outdoor furniture and container gardens (landscaping). Before starting any landscaping or construction project, careful planning is essential. 1. Assess Your Space: Consider the size, shape, and existing features of your garden. Note the amount of sunlight, soil type, and drainage. 2. Define Your Goals: What do you want to achieve with your summer garden? Do you envision a relaxing oasis, a vibrant entertainment area, or a productive vegetable garden? 3. Create a Design: Sketch out your ideas, incorporating both landscaping and construction elements. Consider the flow of traffic, views from inside the house, and the overall aesthetic. 4. Set a Budget: Determine how much you're willing to spend on the project. Prioritise essential elements and be prepared to make compromises. 5. Hire Professionals (If needed): For complex construction projects, consider hiring a qualified contractor or landscaper. Get multiple quotes and check references. · Start with Construction: Complete any necessary construction work before starting landscaping. This will minimise disruption to plants and soil. · Consider Drainage: Proper drainage is crucial for both construction and landscaping. Ensure that water flows away from buildings and doesn't pool in planting areas. · Choose Materials Wisely: Select durable, weather-resistant materials for construction projects. Opt for plants that are well-suited to your climate and soil conditions. · Incorporate Natural Elements: Blend construction elements with natural features. For example, consider using natural stone for retaining walls or incorporating plants into patios and decks. · Think About Lighting: Strategic lighting can enhance both the beauty and functionality of your summer garden. Use a combination of ambient, task, and accent lighting to create a warm and inviting atmosphere. Once your summer garden is complete, regular maintenance is essential to keep it looking its best. · Watering: Water plants regularly, especially during hot, dry weather. Consider installing an irrigation system to automate watering. · Weeding: Remove weeds regularly to prevent them from competing with your plants for nutrients and water. · Fertilising: Fertilise plants as needed to promote healthy growth and abundant blooms. · Pruning: Prune trees, shrubs, and flowers regularly to maintain their shape and encourage flowering. · Cleaning: Clean patios, decks, and other hard surfaces to remove dirt, debris, and algae. By understanding the interplay between landscaping and construction, you can create a stunning and functional outdoor space that you'll enjoy all summer long. With careful planning, thoughtful design, and regular maintenance, your garden can become a true extension of your home.
