With rising property prices and stamp duties, it is no wonder that more and more homeowners are reconsidering moving houses, and opting instead to remain in their existing homes. But does this also mean having to endure cramped and uncomfortable living conditions? Not necessarily.

House extensions provide the unique solution of saving on the cost of moving houses, while also helping homeowners to design and create the perfect additions and extensions to their homes. This makes it possible for homeowners to remain at their current addresses, but enjoying the incredible perks of beautifully designed and perfectly constructed home extensions.

A home extension is a chance for homeowners to add some much-needed space to their home while adding to its design and comfort. It also has the wonderful benefit of increasing the value of the property.

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.

House extensions come in a wide variety of forms. They are most-often differentiated into different types based on the area of the property on which they are constructed. Some of the commonly-seen extension types found in Sutton include:

Rear extensions

Built on the rear of the property, rear extensions offer incredible scope in their design, which in turn makes them perfect for the creation of kitchen extensions, guest rooms, and even office pods.

Side return extensions

Built on the area that runs along the side of the property along with a portion of the rear area, side return extensions are ideally suited for semi-detached and terraced houses. They help create beautiful indoor-outdoor connections that bring in an abundance of natural light and ventilation to your living spaces.

Wrap around extensions

Combining side and rear extensions to create an L-shaped structure that ‘wraps’ around the property, wrap around extensions add incredible width and depth to a home. This allows for the creation of multiple rooms and even open floor layouts.

Multi-storey extensions

Double storey extensions effectively double the square footage of the extension without doubling the roofing and excavation costs. This makes them a cost-effective solution to creating multiple rooms, bathrooms, or even high-ceilinged dining rooms.

The need for planning permission for a house extension in Sutton is largely dependent on the design and dimensions of the proposed extension. This is because house extensions that fall under permitted developments do not need planning permission.

However, for an extension to qualify as a permitted development, it must meet certain criteria and size specifications. These include:

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

However, extensions that do not fall under permitted developments, and those constructed on properties listed in conservation areas, will require planning permission.

Applications for planning permission require detailed diagrams of the proposed extension and may take up to eight weeks to process.

In addition to planning permission, building regulations approval and party wall agreements also need to be considered. These ensure that the proposed build meets the building guidelines and standards.

Good Design and Build oversees this entire process for our clients. From surveying the location, submitting a comprehensive application which includes structural diagrams and calculations, coordinating with the local authority, and securing the requisite planning permission and necessary approvals.

Home extensions offer homeowners the perfect opportunity to customise and build incredible spaces within their properties. This allows them to create beautiful additions that complement their lifestyles and requirements. Some of the most popular designs for home extensions in Sutton feature:

Kitchen extensions

Invariably the most-requested style of home extension, kitchen extensions are wonderful opportunities to combine modernity and elegance to create updated kitchens that are ideally suited to host intimate family dinners or large celebrations.

Garage conversions

Garage conversions are a great way to renew existing space, integrate it into the layout of the house, and create new space and dimension in a home. Their design can be varied as they could be converted into offices, playrooms, bathrooms, or guest rooms. This flexibility makes garage conversions extremely desirable to homeowners.

Loft conversions

A cost-effective solution to convert unused space upstairs into more functional living space, loft conversions are ideal for adding space and value to your home. The versatility of loft conversions allows homeowners to create unique designs perfect for fulfilling space requirements.

Refurbishments

Even without an extension, the existing space within a home can be transformed and upgraded through refurbishments. By designing open-floor plans and optimising the natural light that enters, larger and brighter modern living spaces are created.

The cost of a house extension may range from £35,000 to £140,000. This is because the cost 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

Good Design and Build offer free consultations and quotations for proposed extensions. This allows homeowners to plan, design, and create bespoke extensions within their intended budgets.

Home extensions are incredible opportunities to add space and value to your home. But they must be done right to ensure a good balance of contemporary comforts and timeless elegance. More importantly, the extension should be cohesive with the original structure to maintain its beauty and integrity.

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.
