Growing families, small houses, rising real estate prices, and high stamp duties make for an impossible combination.

Fortunately, house extensions provide the perfect solution for homeowners looking to overcome cramped and uncomfortable living conditions, without incurring the heavy cost and inconvenience of moving houses.

Home extensions help create beautiful, spacious rooms that are the perfect addition to your family home. Best of all? With the right extension specialists, these extensions are the ultimate source of comfort, elegance, and design, while also adding incredible value to a property.

A house extension is a simple but effective solution to resolve many common space dilemmas faced by homeowners.

Home extensions allow homeowners to design and create unique spaces within their homes that are specific to their particular needs. They also enable property owners to increase the value of their homes while avoiding the cost and inconvenience of moving houses.

Based on the area on which it is constructed, home extensions may be broadly classified as:

Rear extensions

Built on the rear of a property, rear extensions are incredibly popular among homeowners as they give rise to numerous possibilities as to how the new space may be used. Rear extensions are commonly built to create kitchen extensions, guest rooms, or even office pods.

Wrap around extensions

These extensions combine rear and side extensions to form an L-shaped extension which essentially ‘wraps’ around your property.

Wrap around extensions add incredible space within your home giving you the option to create an open floor plan or even multiple rooms. However, due to the considerable width and depth added to the property, wrap around extensions almost always require planning permission.

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 generally preferred to wraparound extensions as they do not take up too much of the valuable garden space.

Side return extensions are ideal for creating beautiful indoor-outdoor connections that are a much-coveted feature in modern homes.

Multi-storey extensions

Though more complex than single-storey extensions, two-storey extensions have the potential to create incredible floor space within a home. And as the roofing and excavation costs remain largely unchanged, multi-storey extensions may be a cost-effective solution to add space and value to your property.

Most home extensions in Tower Hamlets do not require planning permission provided that they meet the specific criteria and size limitations of permitted developments. Some of these specifications include:

  • 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

It is important to remember that all extensions built on properties listed in conservation areas require planning permission irrespective of their dimensions.

The planning portal provides homeowners with comprehensive information regarding any specifications to their proposed extensions.

Planning permission can take up to 8 weeks for approval and requires a detailed application including structural diagrams of the proposed extension. In addition to planning permission, building regulations approval and party wall agreements must also be considered to ensure that the proposed extension meets the building guidelines and standards.

Home extensions can be used to design and create a multitude of different rooms and spaces within your home that not only its increase value but also add to its comfort.

Some of the most popular home extension designs in Tower Hamlets feature:

Kitchen extensions

Unsurprisingly, kitchen extensions are one of the most-requested extension designs in Tower Hamlets. They help transform small, dark kitchen-diners into warm, inviting, and beautiful rooms that are ideal for hosting family dinners and celebrations.

Loft conversions

Loft conversions are perfect for utilising awkward loft areas to create much-needed living space in the form of additional rooms, bathrooms, or even reading nooks. Their versatility make them highly valued and they can usually be built without the requirement of planning permission.

Garage conversions

Garage conversions are a simple but effective solution to adding more living space to your property by utilising the often, ill-used garage space. The garage may be converted to a separate additional room, office, or study, or may even be integrated into the floor plan of the interior to create larger kitchen or dining areas.

Refurbishments

Even without an extensive extension, the existing space can be completely transformed through a refurbishment. Changing the layout, creating an open floor plan, and installing cleverly-placed windows can have a dramatic effect in creating bright, airy rooms which help in upgrading your home.

With a variety of factors and variables to consider, house extensions in Tower Hamlets can range in cost from £35,000 to £140,000. Some of the factors that affect the cost of the extension include:

  • Size of the extension
  • Design/ complexity of the extension
  • Location
  • Groundwork
  • Fittings and fixtures
  • Building materials
  • 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.
