Cost Effective Extensions

At Jigsaw Construction Surrey Ltd, we build many extensions for our clients who each have their own budget and reasons for their extension. How cost effective the extension is for each client, varies due to the different factors involved. However, we have put together some of the most cost-effective extensions from a general perspective below:


Loft Conversions

Converting your loft into a functional living space is a popular way to extend your home and increase living space. Having this extra space is perfect for a growing family or overcrowded home. Loft conversions can provide an additional bedroom, office, or playroom and they can increase the value of your home by around 20%.


Garage Conversions

Many properties have an unused garage or use the garage as storage. By converting it, you can increase your family’s living space, and increase the value of your home. A garage conversion can create a new bedroom, home office, or gym. Using existing space rather than building additional space from scratch also saves considerable building costs.


Conservatories

Modern conservatories are extremely versatile and secure, and can serve as an office space, a dining room, an extra living room, a children's playroom, or additional living space. It's a relatively affordable extension option and provides a bright and airy atmosphere. You can choose from various designs and sizes to suit your needs and budget.


Rear Extensions 

This type of extension often involves extending the kitchen or living area. It may require planning permission, but it can add significant value and functionality to your home. A rear extension can transform a home, creating more space at the back of the house and opening it up to the garden. It can be a great solution for terraced houses or for properties that do not have a side return. However, if you do have a side return you can combine a side return extension with a rear extension and maximise the space you have available with a wrap-around extension, making the most of unused outdoor space.


Garden Room

A garden room or a small outbuilding in your backyard can provide additional space for various purposes. It can serve as a home office, studio, or leisure area. Garden rooms are often more cost-effective than traditional extensions as they require less construction work.


 

Porch Extensions 

Adding a porch to the front or rear entrance of your home can be a cost-effective way to enhance your property's curb appeal and provide extra storage space. Porch extensions can be relatively simple structures or more elaborate designs, depending on your preferences.


Basement Conversions

If you have an existing basement, converting it into habitable space can be a cost-effective way to expand your home. This option requires careful planning and consideration of damp proofing, ventilation, and natural light. Some examples of uses for basement conversions include extra bedrooms, a home theatre, or a playroom.


Ways to Cut the Costs of an Extension


If you do want to go ahead with an extension but have limited a limited budget, here are some ways to reduce costs:


1.     Thoroughly plan and design your extension before starting the construction. This will help you avoid costly changes and revisions during the build. Consider the layout, materials, and finishes that offer the best value for your budget.


2.     Determine a budget for your extension and stick to it. Research and gather quotes from different builders and suppliers to get a clear idea of the costs involved. Be sure to include contingencies for unexpected expenses that may arise during the project. Don't automatically choose the lowest quote; instead, evaluate the experience, expertise, and reputation of the builders before making a decision.


3.     If you have the necessary skills and experience, you can consider taking on some of the work yourself or self-managing the project. However, be realistic about your abilities and ensure you can complete the tasks to a high standard. It's important to know when to hire professionals for certain aspects of the project to avoid costly mistakes.



4.     Maximizing the use of existing space can help reduce the overall cost of your extension. As mentioned above, consider converting a loft or garage rather than building a new structure from scratch. This can save on foundation work and some construction costs.


5.     Explore cost-effective building materials that still meet your quality requirements. For example, using engineered wood instead of solid hardwood for flooring or choosing durable but less expensive roofing materials can help lower costs.


6.     Consult with a structural engineer to ensure your extension meets building regulations but avoid over-engineering. Excessive structural work can significantly increase costs. Opt for designs that are structurally sound and efficient without unnecessary complexities.


7.     Gather quotes from multiple suppliers for materials like windows, doors, fixtures, and fittings. Compare prices and quality to find the best deals without compromising on the desired functionality and aesthetics.


Remember, while it's essential to cut costs, it's equally important to maintain quality and adhere to building regulations. At Jigsaw Construction Surrey Ltd, we provide an end-to-end service and work with you to find the best solutions for your budget. We ensure your extension is safe, structurally sound, and compliant with local regulations.

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.
