Loft conversions in Peckham provide the ideal solution for homeowners who need to upsize but not relocate. With the incredible designs and styles on offer, these conversions are soon becoming the go-to solution to not just expand but also elevate homes with contemporary comforts and stylish spaces.

Simply put, a loft conversion is an incredible opportunity for homeowners to transform awkward loft corners into spacious, stylish, and functional rooms. From beautiful bedrooms to cosy libraries, loft conversions offer unlimited potential in designing the ultimate space of comfort and privacy.

Loft conversions are often categorised into these 4 main types based on the existing roof structure and the amount of structural changes involved:

Roof Light Conversions

Often referred to as Velux conversions, roof light conversions are the simplest, and therefore the cheapest, type of loft conversion design. Due to this, they generally do not require planning permission.

Roof light conversions involve transforming the roof space into an additional room by installing skylight windows on the pitch of the existing roof, along with floor reinforcements, insulation, a staircase, and connections to basic utilities.

Dormer Loft Conversions

Dormer loft conversions involve a vertical extension on the roof of the house to create more floor space as well as headroom. These are popular extension options for semi-detached houses that have a sloping roof.

Dormer extensions are of two varieties based on the type of roof extension, namely flat roof and pitched roof dormers. Flat-roof dormers add more living space, whereas pitched-roof dormers are viewed as the more attractive option.

Hip-to-Gable Loft Conversions

A more complex extension, hip-to-gable conversions involve transforming the slope of a hip roof into a gable-style roof with a vertical wall.

This transformation adds considerable floor space and headroom, allowing the creation of an additional room within.

Mansard Conversions

The most complex type of loft conversion, mansard conversions add incredible living space within semi-detached, detached, and terraced homes.

Mansard conversions are typically constructed at the rear part of the house and involve altering the structure of the existing roof to create a flat roof with a sloping wall.

Loft conversions in Peckham can range in cost from a modest £35,000 to a more extravagant £125,000.

This is largely due to the fact that the cost of these conversions is dependent on a large number of factors and variables, including the design and dimensions of the loft conversion, the structural work involved, and even the location.

While you may be tempted to DIY a loft conversion, hiring a professional team to guide you through the process has numerous benefits. These include:

  • Comprehensive planning and design- They will provide a detailed design that takes into consideration your requirements, preferences, and budget.
  • Expert advice- They can help optimise the space by taking into account the layout, materials used, and even council guidelines.
  • Securing the requisite approvals and permits- An expert team will coordinate with the local council and handle the necessary paperwork; saving you time and ensuring compliance with the legal obligations.
  • Project management- A professional team can help oversee all the various tasks involved in a loft conversion build, such as site preparation, construction, connection of utilities, interior finishes, etc.

Simply put, an experienced team can not only help you design a loft conversion that makes the most of the space available while enabling you to stick to a specific budget and timeline, but through their expertise and experience, you can be sure to avoid the many mistakes and errors that would prove costly in the long run.

Loft conversions are incredible opportunities to add space and value to your home. But they must be done right to ensure a good balance of modernity and elegance. More importantly, the loft conversion should be cohesive with the original structure to maintain its beauty and integrity.

Good Design and Build takes care of all this and more. We not only design beautiful loft conversions that are tailored to meet client requirements, but we also oversee the entire process, from planning to completion, ensuring a stress-free experience for homeowners.

This includes surveying the location, designing bespoke loft conversions, obtaining the requisite approvals, daily on-site management of the build, and final handover. With our team of experts, every step of the process is managed with the utmost professionalism and diligence.

This commitment is what enables Good Design and Build to create high-quality, tailor-made loft conversions that are backed by warranties and guaranteed to exceed all your expectations.

The cost of a loft conversion is based on a number of factors, including:

  • The design/ complexity of the loft conversion
  • Location
  • Size of the conversion
  • Structural work involved
  • Building materials
  • Fittings and fixtures
  • Insulation
  • Specialists’ fees, etc.

Therefore, the cost of a loft conversion typically ranges from £25,000 to £125,000.

Good Design and Build offers free consultations and quotations for proposed loft conversions. This allows homeowners to plan their loft conversion budgets and designs to their specifications.

One great benefit of loft conversions is that they can usually be constructed without the need for planning permission. However, this depends on the complexity of the conversion.

For a loft conversion to fall under permitted developments, it must meet specific limitations regarding its size, design, and structural alterations, the type of property on which the conversion is constructed, and where the property is listed.

For example, a loft conversion that features a balcony or a conversion that is done on a property that is listed in a conservation area will require planning permission.

Even those conversions that do not require planning permission will, however, require building regulation approval. This ensures that the building complies with standard building guidelines.

What isn’t really?

Good Design and Build oversees every aspect of the loft conversion project from start to finish. This includes:

  • Primary survey of the location
  • Architectural design of the loft conversion
  • Coordinating with the local council
  • Securing the requisite approvals
  • Daily on-site management of the build
  • Contractual work

And everything in between.

This is because our incredible team comprises surveyors, engineers, architects, builders, technicians, and project managers; enabling us to create high-quality extensions that are backed by warranties and allowing you to enjoy a truly stress-free experience.

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.
