Premium Double Storey Extension Contractors in East Sussex and Kent

Brann New Homes Ltd provides double storey extension services in Crowborough, East Sussex and the surrounding areas. Our work is suited to homeowners who want a high-quality building contractor to manage the key stages of a larger extension project, from early consultation and preparation through to foundations, structure, roof work, glazing, first-fix services, finishing and handover.

Because a double storey extension affects both the ground floor and upper floor, it needs careful planning. The design, structure, roofline, brickwork, window positions, drainage, access, internal layout and finishing details all need to work together. Brann New Homes focuses on creating well-built extensions that feel practical, attractive and in keeping with the existing property.

Add Space Upstairs and Downstairs with a Professionally Built Extension

Many homes in Crowborough have layouts that no longer suit modern family living. The ground floor may feel too small for open-plan use, while the first floor may need another bedroom, bathroom or home office. A double storey extension can help improve both levels of the property in one carefully managed project.

Depending on the property, a double storey extension may be built to the side, rear or as part of a wider home improvement project. It can be used to create a larger kitchen and dining area downstairs, while adding more practical space upstairs for family needs.

A successful double storey extension should look and feel like a natural part of the existing home. Matching brickwork, roof details, window proportions, structural openings and internal transitions all play an important role in the final result.

Brann New Homes can support the main building stages needed to deliver these projects, including groundworks, foundations, brickwork, structural steel, roofing, glazing, insulation, plastering, carpentry, internal finishing and external works.

Our Double Storey Extension Building Process

A double storey extension is a larger building project that needs proper organisation from the start. Each stage should be carefully planned so the new structure is safe, practical, weather-resistant and visually suitable for the existing home. Brann New Homes can support the key stages of double storey extension work, helping homeowners understand what is involved before building begins.

Double Storey Extension Consultation

For every double storey extension in Crowborough, we begin with a clear consultation to understand what you want to achieve from your home. This may include creating a larger kitchen, adding bedrooms, improving the upstairs layout, creating an ensuite, adding a home office or making the property more practical for family living.

We also look at how your existing home currently works across both floors, including the ground-floor layout, staircase position, access, natural light, garden connection and upstairs room arrangement. This helps us recommend a double storey extension approach that feels practical, well-planned and suitable for the property.

During the early consultation stage, Brann New Homes can discuss layout ideas, timescales, budget considerations and key building requirements. Our aim is to give homeowners in Crowborough, East Sussex and the surrounding areas a clear starting point for a professionally managed double storey extension project.

Planning & Building Regulations

Double storey extensions in Crowborough may need planning checks, permitted development consideration and building regulations approval before building work begins. This depends on the property, the size of the proposed extension, the position of the new structure, boundary details, roof design and any local restrictions that may apply.

Before construction starts, it is important to understand what information may be needed to move the project forward properly. This can include architectural drawings, structural calculations, drainage details, building regulations information and any required approvals to help the double storey extension progress in an organised way.

Brann New Homes can help homeowners in Crowborough, East Sussex and the surrounding areas understand the key preparation stages involved in planning a double storey extension. Our aim is to make the process clearer from the start, helping you prepare properly before groundworks, foundations and construction begin.

Groundworks & Foundations

Strong foundations are essential for any double storey extension in Crowborough because the new structure must safely support two levels of building work. Careful preparation at this stage helps create a reliable base for the extension and reduces the risk of problems later in the project.

Depending on the property and extension design, this stage may include site preparation, excavation, trench work, drainage routes, concrete foundations and oversite preparation. These details are especially important for double storey extensions because the foundations need to suit the weight, layout and structural requirements of the completed build.

Brann New Homes can manage the groundworks and foundations stage as part of a professionally planned double storey extension project across Crowborough, East Sussex and the surrounding areas. Our focus is on organised preparation, strong foundations and quality workmanship from the very start of the build.

Brickwork, Roofing & Structural Work

The main structure of a double storey extension in Crowborough needs careful attention to strength, weather protection and appearance. Because this type of extension adds space across two levels, the structural stage must be planned properly so the new build connects safely and neatly with the existing home.

This stage may include brickwork, blockwork, structural steel, floor joists, roof timbers, pitched roofing, matching roofline preparation and external detailing. Each part of the build plays an important role in creating a double storey extension that is strong, weather-resistant and visually in keeping with the original property.

Brann New Homes can manage the brickwork, roofing and structural work stage as part of a professionally planned double storey extension project across Crowborough, East Sussex and the surrounding areas. Our focus is on quality workmanship, reliable construction and a finished structure that is ready for glazing, insulation and internal finishing.

Windows, Doors & Glazing

Windows, doors and glazing are important features of a double storey extension in Crowborough. They help bring natural light into both the ground floor and upper floor, making the new space feel brighter, more practical and better connected to the rest of the home.

This stage may include ground-floor glazing, upper-floor windows, bifold doors, sliding doors, rear doors, rooflights or roof glazing, depending on the design of the property. Carefully planned glazing can improve the appearance of the extension while helping the new rooms feel open, comfortable and suitable for everyday family living.

Brann New Homes can support the windows, doors and glazing stage as part of a professionally planned double storey extension project across Crowborough, East Sussex and the surrounding areas. Our focus is on quality workmanship, practical design and a finished extension that feels light, attractive and built to last.

Plumbing, Electrics & Insulation

First-fix services and insulation are important stages of any double storey extension in Crowborough. Once the main structure is in place, the plumbing, electrics, heating routes and insulation need to be carefully planned so both levels of the new extension are practical, comfortable and ready for everyday use.

This stage may include pipework, electrical wiring, lighting positions, sockets, heating connections, wall insulation, floor insulation, roof insulation and preparation for kitchens, bathrooms or living areas. These details help make the double storey extension functional, efficient and suitable for how the home will be used.

Brann New Homes can help manage the plumbing, electrics and insulation stage as part of a professionally planned double storey extension project across Crowborough, East Sussex and the surrounding areas. Our focus is on organised preparation, reliable workmanship and creating a finished space that works well for everyday family life.

Plastering, Carpentry & Finishing

Once the main construction and first-fix services are complete, the interior of a double storey extension in Crowborough begins to take shape. This is the stage where the new rooms start to feel more finished, with smoother walls, cleaner lines and a more complete layout across both levels of the extension.

Plastering, carpentry, skirting boards, internal doors, architraves, flooring preparation and decorating details all help create a clean final result. Careful finishing is especially important in a double storey extension because the new ground-floor and first-floor spaces need to connect naturally with the existing home.

Brann New Homes can manage the plastering, carpentry and finishing stages as part of a professionally built double storey extension across Crowborough, East Sussex and the surrounding areas. Our focus is on neat workmanship, practical detailing and a finished living space that feels comfortable, well-built and ready for everyday use.

Kitchen, Living Space & Open-Plan Layouts

Many double storey extensions in Crowborough are designed to improve ground-floor living while adding useful space upstairs. This can help create a larger kitchen, dining area, family living space, extra bedroom, ensuite, bathroom or home office, depending on the needs of the property.

Brann New Homes focuses on practical layouts, quality workmanship and clean transitions between the original home and the new extension. This includes considering how the new ground-floor and first-floor spaces connect with the existing structure, natural light, access, rooflines, glazing and internal finishes.

For homeowners in Crowborough, East Sussex and the surrounding areas, a well-planned double storey extension can transform how the whole home feels and functions. Our aim is to create additional living space that feels natural, well-built and suitable for everyday family life.

External Works, Patios & Landscaping

The finished double storey extension in Crowborough should work well from the outside as well as inside the home. External works help connect the new two-storey extension to the garden, creating a practical and attractive transition between the property, patio and outdoor area.

This stage may include patios, paths, garden steps, drainage channels, lawn edging and landscaping areas. These details help manage water, improve access, frame the garden and give the completed double storey extension a cleaner, more professional finish.

Brann New Homes can support external works, patios and landscaping as part of a double storey extension project across Crowborough, East Sussex and the surrounding areas. Our focus is on neat workmanship, practical outdoor layouts and a finished result that feels complete from house to garden.

Building Control, Snagging & Handover

A professionally built double storey extension in Crowborough should be checked carefully before the project is complete. Brann New Homes works through the final stages with attention to detail, reviewing finishes, drainage, doors, windows, plastering, carpentry, external works and the overall presentation of the new spaces.

Where building control inspections or completion documentation are required, these should be handled properly as part of the double storey extension process. This helps homeowners understand that the project has been completed in an organised way, with the right checks in place before final handover.

Snagging is an important part of delivering a high-quality double storey extension across Crowborough, East Sussex and the surrounding areas. Our aim is to make sure the finished extension is clean, practical, professionally presented and ready to become a useful part of everyday family life.

Double Storey Extensions for Growing Homes

A double storey extension can make a home more suitable for long-term use. It can provide space for a growing family, allow for a larger kitchen and dining area, add bedrooms, improve the bathroom layout or create more flexible living space across both levels of the home.

The best double storey extensions are planned around how the home is used now and how it may need to work in the future. This can include the position of the kitchen, access to the garden, staircase layout, upstairs room arrangement, natural light, storage and the relationship between old and new spaces.
