The next best option

Whenever there is a chance of adding more space to your home, it is a possibility you must explore seriously. London isn’t cheap on the property front, and we all want to make the best of what we already have. So, what if we told you loft conversion isn’t the only option to add more space to your property? We know you would love to hear about it. The beauty of this new invention is it can provide that extra bit of space you wish your loft conversion had. Loft pods & house extension pods are novel solutions of the home improvement frontier.

It is a room measuring 3 x 3.5m, usually built over the back half of a property. This loft extension is also called a BUD (Back Upper Dimension). It can be a stand-alone addition or connected to a loft conversion. While stand-alone constructions are more expensive, adding the pod to a loft conversion is more economical and beneficial. Most homeowners have both additions built on the same project to save money and time. It can be a bathroom, a playroom, yoga studio, gym, or office space. By turning the loft pod into a bathroom, you can give your loft bedroom the en suite treatment.

If you already own a loft conversion and the pod addition extends beyond permitted development guidelines, you need to seek planning permission. If you currently do not have a loft conversion and looking to add both at the same time, we can build both to recommended specifications. Living in a conservation area, a heritage area, or a listed building, will need planning permission for both constructions.

You will also require permission if the following is true;

  • Proposed roof space for a terraced house exceeds 40 cubic metres
  • Proposed roof space for semi-detached and detached house exceeds 50 cubic metres
  • Extension reaches beyond the plane of the existing roof
  • Extension rises higher than the highest part of the roof
  • Material is different in appearance to the existing house
  • A veranda, balcony, or a raised platform is in the design

You must also adhere to building regulations, which are crucial for both loft conversions and pods. These include;

  • Ensuring the structural strength of the loft and pod floors
  • The existing roof of the property is in no danger of instability
  • A fire escape that can be easily accessed by both loft and pod is available
  • A staircase built to safety standards provides access to the loft and pod
  • Proper insulation between the new additions and the rooms below

A Loft Pod in London can start from £23,000 onwards, depending on the size and availability of a loft conversion. Good Design & Build offers comprehensive guidance and assistance in all permission requirements. Our engineers and architects draw up designs and plans for both additions using expert knowledge and insight into individual requirements.

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.
