Designing the Ultimate Kitchen Extension for your 1930s Home

Whether you utilise the kitchen to prepare elaborate meals for family and friends, or simply to make rushed lunches on busy mornings; the kitchen invariably takes centre stage of your everyday routine. That being said, most kitchens in period homes do not cater to the needs of the modern household.

A kitchen extension helps you to change that. Kitchen extensions not only allow you to expand, extend, and upgrade your kitchen to suit your family’s lifestyle, it also helps you to add space and value to your beautiful home.

And with the right help, smart designs, and expert advice, your favourite room can become even more inviting and appealing than ever before.

Don't move. Extend in style

We can save you the hassle that comes with moving not to mention the heavy stamp duty! Adding an extra loft bedroom or enlarging the living kitchen dining space on ground floor is an economical way of transforming your home to suit growing needs. The projects can range from £40-100K depending on your requirements and can be completed within 8-16 weeks.

A kitchen extension is the perfect opportunity to design and build your dream kitchen.

From upsizing the space to upgrading your fittings, a kitchen extension allows you to create the ultimate modern kitchen area, that is the perfect complement to your home and lifestyle.

The type of kitchen extension constructed is largely determined by the area available within the property. Some of the most common types of kitchen extensions for 1930s homes include:

Rear extensions

Built on the rear of the property, these extensions offer incredible space and views for your kitchen or dining area. With bi-folding, glazed doors, you can help bring the outdoors in, or even create an alfresco-style dining area that is ideal for entertaining.

Side return extensions

These extensions utilise the area that runs along the side of a property along with a portion of the rear. They do not use too much of the valuable garden space and therefore, are highly-valued by homeowners.

Side return extensions help create beautiful indoor-outdoor connections that are much sought-after in modern dining rooms.

Wrap around extensions

A combination of rear and side extensions, wrap around extensions add incredible space to your home. The width and depth added can be utilised to design an open plan kitchen, a walk-in pantry, or a large dining room.

Double-storey extensions

Multi-storey extensions may be used for more than creating additional bedrooms upstairs. They are perfect for expanding your kitchen, designing an open plan living are, or even creating high-ceilinged dining areas.

The need for planning permission for a kitchen extension in your 1930s home is dependent on the design and dimensions of the proposed extension.

Most extensions will not require planning permission if they meet the criteria for permitted developments. These criteria and specifications include:

  • The property must not be listed or located in a conservation area.
  • 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.

If the extension does not fall under permitted developments, planning permission will be required. This process involves the submission of a comprehensive application which can take up to 8 weeks for approval.

Good Design and Build oversee this entire process for our clients. From the initial survey and submission of detailed plans, to coordinating with the local council and securing the requisite approvals.

This allows homeowners to enjoy a stress-free kitchen extension experience.

When it comes to the kitchen, there is no dearth of ideas and concepts that we wish to incorporate and include. But knowing how to convert your kitchen into a modern space without losing the charm and authenticity of your 1930s home requires a delicate balance.

Some of the best ideas for kitchen extensions in London, that transform your kitchen into the perfect space for your family, include:

The open plan kitchen

A favourite of modern homeowners, the open plan kitchen usually features a living area, dining room, and kitchen within a single space that is inclusive and barrier-free.

Kitchen-conservatory combo

When your kitchen opens to the outside, integrating the space with a conservatory helps maximise the bright, airy feel and creates the perfect spot for hosting and entertaining.

An ode to the classics

Perfect for period properties, this style of kitchen extension plays homage to the architectural style of the 1930s, and highlights its unique features without hiding them. This generally involves embracing period features such as ceiling beams and tiled fireplaces, and incorporating them to add character to the kitchen interior.

Kitchen extensions in London can cost between £35,000 to £100,000. This is because the cost of a kitchen extension 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

It is therefore a good idea to plan a budget that takes these factors into consideration in order to create the best possible extension.

Good Design and Build offer free consultations and quotations for proposed extensions. This allows homeowners to plan their kitchen extension budgets and designs to their specifications.

Being the ultimate family room, the kitchen needs to be designed to be convenient and comfortable. It also needs to seamlessly integrate with the existing property without being jarring to its structure or style.

By considering the process involved and the comprehensive planning and management required, it is vital to choose the right kitchen extension specialist.

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.
