West Norwood in Lambeth and its surrounding areas offer homeowners the perfect balance of a quiet residential neighbourhood with quick access to the bustling city centres. As such, homeowners in Lambeth are rightfully reluctant to leave their homes when faced with the dilemma of cramped living spaces.

This is where home extensions come in.

Home extensions allow homeowners to add much-needed space to their properties at a fraction of the cost and inconvenience of moving houses. Home extensions can be customised to create spaces that perfectly suit individual requirements and modern lifestyles. Best of all? These extensions add incredible value to a property.

So how do you maximise on this investment? Simply consult the best extension specialists who can help you to create the ultimate extension.

A house extension in Lambeth is a unique opportunity for homeowners to add space to their homes while increasing the value of the property.

House extensions can be designed and created to meet the specific needs and requirements of homeowners, and therefore, these customised spaces are also ideal for adding character and personality to a home.

Home extensions are broadly classified into different types based on the area of the property on which they are built. Some of the most popular types of home extensions, which are ideally suited for Lambeth properties, include:

Rear extensions:

Built on the rear of a property, rear extensions offer incredible versatility in their design and function. This means that they can be used to create kitchen extensions, guest rooms, or even office pods.

Wrap around extensions:

Wrap around extensions are essentially a combination of rear and side extensions that create an L-shaped structure that ‘wraps’ around the property. This type of extension adds great width and depth to the property and can be used to create multiple rooms, large kitchen-diners, and open floor plans.

Side return extensions:

Side return extensions utilise the area that runs along the side of a property as well as a portion of the rear. These extensions are highly sought-after by homeowners as they do not take up too much of the valuable garden space and are perfect for creating beautiful indoor-outdoor connections that brighten up modern dining rooms.

Multi-storey extensions:

Multi or double storey extensions add incredible floor space to a home and are considered to be highly cost-effective. This is because they essentially double the square footage of the extension without doubling the roofing or excavation costs. Two storey extensions are useful in creating extra bedrooms, bathrooms, and even play areas within the home.

Not necessarily. The requirement for planning permission for home extensions in Lambeth is largely dependent on the design and dimensions of the proposed extension.

If the 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 oversee this entire process for our clients. This 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.

With almost every conceivable design option available, homeowners in Lambeth are able to create unique spaces within their homes to suit their individual requirements and lifestyles. Some of the most popular designs and ideas for home extensions in Lambeth feature:

Kitchen extensions –

By far the most popular style of home extension, kitchen extensions help convert small, dark kitchen-diners into beautiful, warm, and inviting spaces which are ideal for hosting intimate lunches and large celebrations alike.

The installation of the latest fittings completes the transformation to create the ultimate modern kitchen.

Loft conversions –

Loft conversions transform awkward loft spaces into beautiful and functional rooms that add much-needed floor space and value to a home. The versatility of loft designs enables homeowners to create additional rooms, bathrooms, or even office nooks.

Garage conversions –

Garage conversions are ideal for converting the often ill-utilised garage space to create additional floorspace within the home. The new space may then be used as a home office, guest room, or utility room. Or it can even be incorporated into the interior layout of the property.

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 Lambeth can cost between £35,000 to £140,000.

This is because the cost of a home extension is dependent on a large number of factors and variables, including:

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

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.
