The historic magnificence of Surrey and architectural brilliance of Greater London are a part of Croydon’s charm. With the infamous Croydon Football Club in the vicinity, your life at Croydon would never have a dull moment. Additionally, the Museum of Croydon infuses legend to suburban Croydon, Wandle and South Norwood Country Parks offer companionship with nature. With its touching distance to both the seaside and countryside as well as the heart of London City, Croydon is an ideal suburb to build your dream home and house extensions in Croydon to further explore the suburb. While the age-old architecture is a heritage, it is our belief that periodic homes need a touch of modernization and revival to stand out and the fusion of both historic and modern design is skillfully crafted by the best architects and builders in the business.

A variety of house extensions are made possible in Croydon.

Side Return Extension – A side extension can transform an awkward space and add some balance.The leftover garden space at the back of period properties along the boundary wall is a design centuries old. By incorporating it into the main floor area of the house, you can widen the kitchen or create a diner, a utility room, or a bathroom.

Rear Extension – allow more natural light into your home with a rear extension that can beautifully blend the boundary of inside and out. It lengthens the floor area of your home towards the back by building onto the rear garden. This single-storey rear extension is a popular addition for open-concept kitchen extensions; it can even include an alfresco patio.

Wraparound Extension – Synthesise a side return and a Rear Extension to create a bigger living space. It widens and lengthens the proportions of your home for a wall-less expansive area shaped like an L or multiple individual rooms.

Double-storey extension – an ideal extension to save space on your ground floor and create a better space for a wider living area and rooms, double storey extensions offer the benefit of a South London view. 

A home extension falls under permitted development rights and usually requires no council permission. However, PD rights are only valid under the following conditions;

  • The property for the proposed extension is not on designated land or isn’t a listed one.
  • The extension does not take up more than 50% of your home’s existing land.
  • No new addition extends above the highest part of the roof.
  • Rear extensions for detached houses extend only up to 8m, and for semi-detached houses, only up to 6m.
  • Single-storey extensions are no taller than 4m.
  • Double-storey extensions do not extend beyond 3m or be within 7m of a boundary opposite the rear wall.
  • Double-storey windows on side elevation are obscure-glazed and non-opening.
  • There are no balconies or terraces featured in the new building.

We also assist with Party Wall Agreements and work with party wall surveyors and structural engineers to ensure your new building is lawful and remains litigation-free.

Loft conversion – if you feel your period home needs more space, options are available to expand upwards or outwards from your existing square footage. Utilise the generous space of your period home’s attic with a loft conversion.

Kitchen extension – Expand the kitchen space of your home into a more cosy dining room enclosed in the kitchen allowing convenience and intimacy with your family and house guests. A kitchen extension could also serve as a storage space or an indoor garden permitting ventilation and natural beauty into your kitchen. 

Storey extension  – if your upper floor is smaller than you anticipated, a storey extension can serve the purpose of adding more space into your bedrooms and create a special family room. An additional bedroom, study or a terrace can add sophistication to your home with a storey extension.

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.
