Surrounded by wild green open spaces and marked by riverside pleasantness, Putney is South-West London’s answer to the freshness of the English countryside. As a property-rich spot on the south bank of the Thames, you could be living in one of its many Victorian cottages or Edwardian homes. While these homes are a testament to the craftsmanship of London’s golden era of housing, they do not characterise present-day Londoner’s varying needs. It is where we come in with harmonious house extensions Putney that magnify space with exceptional results. We bring together architectural elements that add more to your floor plan with seamless continuation. Our high-quality building service extends to the Putney area for exterior and interior design that surpasses ordinary home renovation.

Side Extension – the alleyway along the side of Victorian and Edwardian homes has been a classic convenience for enlarging the kitchen area. By replacing the party wall with an interior wall, the property can extend onto this under-used garden space. It creates a kitchen extension or other spaces such as a utility room, a bathroom, or a separate garden dining room.

Rear Extension – from one boundary wall to the other, this extension spans across the entire width of the property at the rear. As the addition sits on the back garden, it is more exposed to natural light and outdoor space. It is suited well for an open-plan kitchen/dining area or individual spaces including, a living room, entertainment room, gaming room, or a home office.

Wraparound Extension – by joining a Side Return and a Rear extension, an L-shaped Wraparound is formed. It allows you to design a generous-proportioned open plan layout or add multiple rooms, including a bedroom.

Double-storey Extension – Side, Rear, and Wraparound extensions can have multi-stories. Usually, double-storey extensions add twice the space using the same excavation and roofing costs.

Loft conversions – if you do not want to sacrifice any of your garden space, then look to your loft. If your roof has sufficient space for a loft conversion, it is another home extension method to add to the square footage.

A house extension is a Permitted Development, which means you have the right to build without permission. However, PD rights only apply under the following conditions;

  • Your property is not listed and not located on designated land.
  • Only 50% of the land area must contain extensions.
  • Side extensions must be limited to 4m in height and only be half the size of the existing house.
  • The height of the extensions cannot exceed the highest part of the roof, nor can the extensions be higher at the original eaves.
  • Single-storey Rear Extensions shall not extend beyond the rear wall by more than 6m if the house is terraced or semi-detached and 8m if the house is detached.
  • Any extension with more than one storey should not extend beyond the property’s back wall of the house by more than 3m or be within 7m of a boundary opposite the rear wall.
  • When extensions come within 2m of a boundary, the maximum height at eaves should be 3m.
  • Angular extensions avoid impeding sightlines for neighbours. Asymmetrical pitched roofs and faceted ceilings offer versatile shapes.
  • Overhead glazing can retain some of the greenery you lose with garden space.
  • A double-height glazed atrium with solar reflective coating has a stunning effect for a rear extension.
  • Dig a basement to free up space for a decent-sized new kitchen or a large cinema room if your house doesn’t have a wine cellar to convert.

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.
