It’s confirmed. Richmond upon Thames is the ‘Happiest Place to live in London’.

And no wonder. The beautiful homes, upscale restaurants, and stunning parks create an area that residents never want to leave.

Fortunately, they never need to. Even when growing families and changing lifestyles can lead to confined living conditions that can cause homeowners to consider relocating.

This is because home extensions give homeowners the chance to increase the square footage of their homes, and avoid the cost and inconvenience of moving houses, while also adding comfort and value to their properties.

House extensions are the ultimate forms of home improvement, that can help transform any space into a newly-designed, modern expansion that beautifully integrates with the existing structure.

Home extensions provide the simple, yet elegant, solution of avoiding the expense and inconvenience of moving homes. The versatility and adaptability of home extension designs enable homeowners to create the ideal space within their homes that not only adds more living space, but also upgrades their homes to create the ultimate dream extension.

The type of house extension built depends on the area available within the property, the additional space required, and the budget allocated. House extensions vary in their complexity and as such, careful consideration must be given to its design. The types of house extensions ideal for properties in Richmond upon Thames include:

Rear extensions

An incredibly versatile and popular type of extension, rear extensions occupy the rear area and back garden area of a property. These types of extensions can be used to create guest rooms, kitchen extensions, and office pods.

Wrap around extensions

Wrap around extensions are essentially a combination of rear and side extensions that form an L-shaped structure that ‘wraps’ around a home. These extensions add enormous width and depth to a property, and are ideal for creating multiple rooms or even open floor layouts.

Side return extensions

Side return extensions utilise the area that runs along the side of the property along with a portion of the rear area. These extensions are popular among homeowners as they do not use up too much of the valuable garden space. Side return extensions have enormous potential in creating the beautiful indoor-outdoor connections that are coveted in modern dining rooms.

Multi-storey extensions

Though more complex than single-storey extensions, multi-storey connections are highly sought-after as they essentially double the square footage of single-storey extensions without adding to the roofing and excavation expenses. These extensions are perfect for adding bedrooms, bathrooms, and offices.

Yes and no.

The requirement for planning permission for home extensions in Richmond upon Thames is based largely on the design and dimensions of the proposed extension. Extensions that meet the specific criteria of permitted developments do not require planning permission. Whereas extensions constructed on properties listed in conservation areas will invariably require planning permission.

In addition to planning permission, building regulations approval and party wall agreements must also be secured to ensure that every aspect of the extension build complies with standard building guidelines and regulations.

Good Design and Build oversees this entire process for all our clients. This includes:

  • Initial survey of the location
  • Submitting architectural diagrams of the proposed extension
  • Coordinating with the local council
  • Securing the requisite approvals

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

With a variety of designs and styles, home extensions can easily be customised to suit the specific needs of homeowners. That being said, some of the most popular extension styles seen in Richmond upon Thames include:

Kitchen extensions

Kitchen extensions help you to transform small, dark kitchen-diners into warm, open, and inviting spaces that cater to modern homes and lifestyles. With the installation of the latest fittings, these kitchens quickly become the centre of a family home and are ideal for hosting celebrations.

Garage conversions

Garage conversions are relatively quick and simple solutions to increasing the living space of a home. The versatility of the space, and the possibilities it creates make garage conversions extremely desirable among homeowners. The converted space can be incorporated into the functional layout of the house creating much-needed living space and additional room.

Loft conversions

A popular option among homeowners, loft conversions offer incredible versatility in their design and are perfect for adding that extra bedroom or office nook that adds so much value to a property. Loft conversions utilise the awkward loft corners and convert these spaces into valuable living space.

Refurbishments

Not all homes require extensive extensions. Sometimes an innovative approach to transforming the existing space involves changing the layout, creating an open floor plan, and installing well-placed skylights or windows to create a brighter and larger room.

Home extensions in Richmond upon Thames can cost anywhere between £35,000 to £140,000. This is because the cost of a home extension depends on a number of factors such as:

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

It is therefore a good idea to plan a budget that takes these factors into consideration in order to create the best possible home extension.

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.
