An excellent and affordable alternative to moving houses is to invest in a home extension. Home extensions allow homeowners to design and build extensions that can add more living space to a property. This allows property owners to enjoy the perks of the added space without the hassle of a move.

Home extensions in Barnet are the ideal opportunity to create extra space to your home, increase its value, and add a unique design element of your own.

But in order to achieve the perfect house extension, it is imperative that you begin this process with a clear idea of the extension you want to create, and choose the best extension specialists for this crucial investment.

A house extension is an opportunity for homeowners to design and create a piece of their home through bespoke extensions that add considerable space and value to a home.

When done right, home extensions in Barnet have the potential of transforming the original property by creating uniquely designed rooms that are the perfect blend of beauty and functionality.

House extensions may be categorised based on the area of the property on which they are built. As such, home extensions in Barnet include:

Rear Extensions

Built on the rear of a property, rear extensions are incredibly versatile in their design and function. They may be used to create kitchen extensions, extra rooms, or office pods.

Side return extensions

Side return extensions utilise the area that runs along the side of a property and a portion of the rear. These extensions are valued as they do not use up too much garden space. Side return extensions are ideal for creating indoor-outdoor connections that help bring in natural light to create brighter spaces.

Multi-storey extensions

Though more complex than single-storey extensions, two-storey extensions add incredible floor space within a property. The best part? The roofing and excavation costs remain largely unchanged even as the square footage is essentially doubled.

The answer to this question is not always straightforward and depends largely on the design of the proposed extension. This is because extensions that fall under permitted developments do not require planning permission.

However, the criteria of permitted developments only allow extensions which meet specific size and height limitations. This includes a maximum height of 4m for single-storey extensions, and a maximum width of 50% of the original house for side extensions. Most importantly, the property should not be listed in a conservation area.

The process of applying for and securing planning permission can take up to eight weeks and requires a comprehensive application detailing the proposed extension.

Homeowners must also apply for building regulations approval to ensure that every aspect of the extension build complies with building guidelines and standards.

Good Design and Build oversee this entire process for all our clients. This includes surveying the location, submitting structural diagrams of the proposed extension, coordinating with the local council, and securing the requisite planning permission and building regulations approval.

Being the perfect mix of city and country, homes in Barnet are a true representation of timeless beauty and modern designs. As such, home extensions constructed here must be carefully considered so that they seamlessly integrate with the original structure and maintain its beauty and integrity. Some of the most sought-after extension designs for Barnet include:

Kitchen extensions

Invariably the most popular extension design, kitchen extensions are well-worth the investment as they help convert small, dark kitchen-diners into bright, spacious and inviting rooms that are perfect for hosting intimate family dinners as well as large celebrations.

With the addition of the latest fittings, they can be well-suited for modern homes and lifestyles.

Loft conversions

Loft conversions work well to convert awkward and ill-used loft spaces into functional and elegant additional floor space. Loft conversions are often utilised to create extra rooms, bathrooms or even office nooks and playrooms.

Garage conversions

Garages that are normally used as storage areas can be converted into valuable additional living space by incorporating the garage space with the interior layout of the property. This space can then be designed into a home office, guest room, playroom, or even a utility room.

Refurbishments

For homeowners that do not wish to extensively extend, it is still possible to transform the existing space via refurbishments. This involves remodelling the space to change the layout, creating open floor plans, and increasing the natural light that enters into the room through the addition of well-placed windows. All of this enables the creation of brighter and more spacious areas that better fit in to your lifestyle.

The cost of a home extension in Barnet can range from £35,000 to £135,000.

This is because the cost depends on a large number of factors including, but not limited to:

  • The size of the extension
  • The design/complexity 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.

A home extension allows you to create your dream home, with the space you require, and at the address at which you want to remain. It saves you from the unnecessary cost and inconvenience of moving houses. And it allows you to design and create a part of the family home.

All things considered; home extensions are a great investment.

However, to make this investment truly worthwhile, it must be handled with the care and professional expertise it warrants.

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.
