Transforming your home to create additional living space is no longer an implausible dream.

Home extensions allow you to design and create your ideal extension while enabling you to remain at your current address. This offers homeowners the chance to extend in style while creating bespoke extensions that are specific to their needs.

And with the right extension specialists, these extensions can prove to be a valuable investment.

A home extension is an incredible opportunity for homeowners to upsize and upgrade their residences to suit their specific needs and lifestyles. Home extensions provide homeowners with realistic solutions to common space dilemmas, at a fraction of the cost and inconvenience associated with moving houses.

Home extensions are generally classified into different types based on the area of the property on which they are built. As such, home extensions in Charlton commonly feature:

Rear extensions

Built on the rear of a property, rear extensions offer incredible versatility in their design and functionality. Rear extensions may be used to create the ever-popular kitchen extensions, guest rooms, play rooms, or even office pods.

Side return extensions

These extensions utilise the area the runs along the side of a property as well as a portion of the rear. Side return extensions are highly sought-after by property owners as they do not take up too much of the valuable garden space. These extensions also help create beautiful indoor-outdoor connections that add an abundance of light and ventilation.

Wrap around extensions

These extensions are essentially a combination of rear and side extensions that creates an L-shaped structure that ‘wraps’ around the property. With the incredible width and depth created, wrap around extensions are ideal for creating multiple rooms, large kitchen-diners, and even open floor plans.

Multi-storey extensions

Multi-storey extensions add a great deal of floor space to a home as they effectively double the square footage of an extension. Best of all? The roofing and excavation costs remains unchanged while homeowners obtain additional space to create bedrooms, bathrooms, or even high-ceilinged living areas.

The requirement for planning permission for home extensions in Charlton is largely dependent on the designs and dimensions of the proposed extensions.

If an extension falls under permitted developments, then no planning permission will be required. However, permitted developments have specific criteria and size limitations. For example:

  • Extensions must not take up more than half the land around the original house
  • Extensions cannot be higher than the highest part of the existing roof
  • Materials used for the exterior of the extension must be similar in appearance to that on the exterior of the original house
  • Side extensions can only be single-storied and cannot exceed more than half the width of the original house

Additionally, it is important to remember that extensions built on properties listed in conservation areas will require planning permission irrespective of their dimensions. Homeowners can visit the planning portal for up-to-date, comprehensive information regarding any specifications for the proposed extension.

Depending on the complexity of the extension, planning permission can take up to 8 weeks for approval, and requires a detailed application including structural diagrams of the proposed extension.

Building regulations approval and party wall agreements must also be considered to ensure that the proposed extension meets the building guidelines and standards.

Good Design and Build oversees this entire process for our clients, which includes:

  • Initial survey of the location
  • Architectural design of the extension
  • Submission of a comprehensive application
  • Coordinating with the local council
  • Securing the requisite approvals

This allows homeowners to enjoy the extension process hassle-free.

Ideally, the newly created space could be used to design a myriad of different rooms and spaces specific to the needs of the homeowners. However, it is also important to ensure that the design of the extension seamlessly integrates with the beauty and architecture of the existing structure.

Some of the more popular home extension designs for Charlton homes feature these extensions that combine contemporary design and functionality with timeless style and elegance:

Kitchen extensions

A family favourite, kitchen extensions help transform small, dark kitchen-diners into beautiful, warm, and inviting spaces that are a perfect addition to a modern home.

Loft conversions

An ideal way to convert awkward loft spaces and transform them into valuable, and functional living space, loft conversions offer homeowners the chance to create additional bedrooms, bathrooms, or even study nooks.

Garage conversions

Converting the often, obsolete garage space can help add much-needed space within a home in the form of play rooms, offices, or utility rooms.

Refurbishments

Even without an extensive extension, the existing space can be transformed through innovative refurbishments. Changing the layout, optimising the natural light, and creating open floor plans are some of the ways by which beautiful, larger, and brighter living spaces can be created.

Home extensions in Charlton can range from £35,000 to £140,000. This is because the cost of home extensions is dependent on a large number of factors including:

  • The design/ complexity of the extension
  • The size of the extension
  • Location
  • Groundwork
  • Building materials
  • Fittings and fixtures
  • Specialists’ fees

Good Design and Build offer free, no-obligations consultations and quotations for proposed extensions. This allows homeowners to design their dream extensions within their intended budgets.

Home extensions offer homeowners the unique opportunity of adding incredible value to their properties. This is because beautiful, functional extensions can increase the value of a property by up to 20%.

How we deliver projects

Our process is simple and divided into two distinct phases with separate contracts: Design and Build. As a client you only commit to one phase at a time depending on what stage of the process you are in. Each phase consists of three stages as described below.

1. Design

This is the kick-off point for your project. We carry out a complete architectural measured survey of the property. This allows us to create accurate CAD design drawings. This is followed by a design meeting to start discussing your ideas in more detail.

2. Planning

At this stage we finalise the designs with you and start preparing planning applications as needed. We place a high priority on ensuring that plans, designs and schedules are all based on a thorough and detailed understanding of planning guidelines. We co-ordinate with local authorities until the decision is made, and the planning approval is secured.

3. Technical

Once the planning consent is secured, we translate the design drawings into more detailed technical drawings for the purposes of building control and construction. This also includes specifications and structural calculations. At this stage, we will also submit to you our ‘no obligation’ quote for the build phase.

4. Pre-build

90% of our clients decide to stick with us after the design phase is completed. Once the build contract is signed, we kick off the process by making sure all the pre-build processes are complete. These include assistance with party wall agreements, Thames Water build over agreement, submitting building control application, and preparing method statements etc as needed. This stage ends with a pre-start meeting with your foreman before the actual build begins.

5. Build

One of our foremen will be dedicated to your project and will be on-site to manage everyday works. Our project managers will be overseeing the works to make sure they are completed to high standards, within your budget and on time. Throughout the process we will keep you updated with the progress and coordinate the works with third parties such as kitchen or flooring suppliers. We will also advise and guide you to choose any suppliers if needed.

6. Handover

As the build draws to finish, we will help to iron out any ‘snags’ to make sure everything is completed to your satisfaction. We will put together all necessary certificates such as gas, electricity and building control completion along with warranties for glazing, boiler etc. At the final completion meeting, we will hand you these documents, together with the keys to your house. Needless to say, you can contact us any time after this, if you want us to look at something.
