With its superb parks, fantastic museums, and great schools, North Dulwich really is the complete package. And its beautiful homes are simply the icing on the cake.

House extensions in North Dulwich therefore provide homeowners with the perfect chance to elevate their homes and personalise their living spaces without having to bear the heavy cost and inconvenience of moving houses.

And with the right expert help, it becomes easy to not just transform your home but also create the ideal space that adds incredible value to your property.

A house 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.

House extensions come in a variety of designs but are most often categorised based on the area of the property on which they are constructed. House extensions commonly found in North Dulwich include:

Rear extensions

Built on the rear of a property, these extensions offer incredible versatility in their design and use. Rear extensions are generally utilised to create kitchen extensions, guest rooms, or even office pods and playrooms.

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. They are ideal for creating beautiful indoor-outdoor connections that bring in abundant light and ventilation to a home.

Wrap around extensions

Wrap around extensions are a combination of side and rear extensions that creates an L-shaped structure that ‘wraps’ around the property. These extensions add great width and depth, and therefore can be used to create multiple rooms, large kitchen-diners, or even open floor plans.

Multi-storey extensions

Two storey extensions, though more complex than single storey extensions, add incredible floor space to a property. They are also extremely cost-effective as they effectively double the square footage of the extension without doubling the roofing and excavation costs. Multi-storey extensions help create multiple rooms and bathrooms within the property.

The requirement for planning permission for home extensions in North Dulwich 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.

Seamlessly integrating the extension into the original structure is crucial in designing successful house extensions in North Dulwich. Some of the best home extensions feature:

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

Loft conversions are ideal for creating additional bedrooms upstairs. The design variability and functionality of loft conversions provide homeowners with many options on how to optimise unused areas of the home and convert them to useful spaces.

Kitchen extensions

Invariably one of the more popular extension styles, kitchen extensions help to open up the kitchen area into a warm and inviting space. With the right fittings and fixtures, the area can be converted into a modern space that is perfect for hosting family dinners and which also adds great value to a property.

Refurbishments

Not every home improvement project necessitates an extension. The functional space of a home can be increased and improved upon by utilising the existing area and maximising its potential. This generally involves refurbishing and renovating the space by the creation of open floor plans and optimising the natural light that enters into the room. This helps to construct a larger, brighter, and more modern living area.

The cost of a house extension in North Dulwich can range from £35,000 to £140,000. This is because the cost of home extensions depends on a wide variety of factors including:

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

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.
