Our Most Popular Side and Rear Extension Projects

Project Requirement

The client’s kitchen had a size of 3mx4m, which was proving to be quite small for their family. They wanted it to be extended into the large backyard to a size of 6mx5m without blocking the sunlight. 

 Challenges

  • The client was living at the site and utilizing the kitchen.
  • Structurally, a window needed to be repositioned in accordance with local authorities. 

How did Essex Construction and Builders overcome the challenge?

  • We provided a makeshift kitchen for the family for the duration of the project and completed the extension within a quick deadline whilst ensuring that the client experienced minimal intrusion.
  • The window in question was repositioned.
  • To satisfy the client’s requirement for a sunlit extension, we also added automatic motorized skylights with rain sensors. 

Project Requirement

The client’s kitchen had a small size of 3mx3m. They wanted to extend it to 6mx5m. They wanted a large, airy, well-lit kitchen with a large kitchen island, hidden storage shelves, and seamless design with the latest German equipment.

 Challenges

  • The client’s tenants were living at the site and utilizing the kitchen and it was crucial to keep the kitchen functioning.
  • The boiler was supposed to be relocated. Since there were tenants staying at the house the heating could not be interrupted for prolonged durations.

How did Essex Construction and Builders overcome the challenge?

  • We planned out the work in a way that gave the current tenants use of the existing kitchen at all times and completed the extension within a quick deadline.
  • First, a new system boiler with a mega flow tank was installed to accommodate the new requirements of underfloor heating. The old system was kept operational during this time. Once the new system was up and running, we just shifted the boiler outputs.
  • To satisfy the client’s requirement for a well-lit extension, we added two skylights.
  • We opted for shelf cabinets with concealed handles to give a unified look to the storage units. The kitchen chimney is also hidden behind the storage units.
  • The latest German equipment, including a zip tap, wireless charging tower with extension ports, latest microwave and oven, and hob were added.

Frequently Asked Questions

We provide rear, wrap-around, and side extension services in the Essex region. This includes both single and multi-storyed extensions.

  • Side Extension: Usually the minimum size of a side extension is half of your main dwelling (50%). However, this size can be more dependent on the size of your garden width.
    • Wrap-around extension: This is a type of side extension that brings a side alley into the main dwelling and can be used as an excellent source of light for the main dwelling via beautifully laid out skylights.
  • Rear Extension: For a terraced and end-of-terrace house, the allowed rear extension size is between 3m-6m depending on the borough. For a detached house, you can extend your rear up to 9m. All these rules are contingent upon the extension not taking up more than 50% of your original garden space.

Note: Anything outside local permitted development rules will require full planning permission.

A 3m rear extension comes under permitted development regardless of the house type. All other extensions require full planning permission wherein the allowed size is evaluated on a case-by-case basis.

Extensions can range between £18,000 – £90,000. Contact us for a free quote using the contact form below or any of our other contact details at the end of this page.

An extension can increase your property’s valuation by up to 23%.
