Double Storey Extensions in Selston

Selston property: what makes the work different here

Selston is a well-established village situated roughly 11 miles northwest of Nottingham city centre, characterised by a varied mix of housing spanning early twentieth-century miners' cottages, post-war semi-detached family homes, and modern detached residential cul-de-sacs. Properties along Nottingham Road, Mansfield Road, and surrounding residential avenues often occupy generous plots, making them prime candidates for substantial double storey extensions. However, the village's historic industrial and colliery background means ground stability must be carefully checked during initial foundation design. Many 1930s to 1970s semi-detached and detached homes feature traditional red brickwork and hipped or gable-ended pitched roofs, which require thoughtful architectural detailing so that two-storey additions blend naturally with the original house. Rear gardens are frequently deep enough to accommodate large two-storey rear footprints without compromising outdoor amenity space, but boundary proximities and mutual overlooking across neighbouring plots require sensible window placements. Our extensive experience working with local housing stock across Selston allows us to design structurally robust, visually complementary extensions that respect the streetscape while providing substantial modern family living space.

What double storey extensions involves

Building a double storey extension is a comprehensive structural undertaking that starts deep underground. Following initial site setup, we excavate trenches to engineer-specified depths, install drainage diversions, and pour concrete strip or trench-fill foundations. Once the ground-level concrete slab and damp-proof membranes are certified, our bricklayers construct the cavity walls, incorporating rigid insulation and ties, matching the exterior brickwork of your existing Selston home. Heavy structural steels are hoisted into place to support upper-floor loads and open up the lower living areas. We then install structural floor joists, raise the first-floor external masonry, and build the roof structure using timber rafters or pre-fabricated trusses, finishing with matching tiles or slates. Once weathertight, our internal teams run first-fix plumbing, heating pipework, and electrical cabling before fitting high-performance insulation and drylining. The critical knock-through stages are carried out using heavy-duty props and lintels. Finally, plastering, second-fix carpentry, joinery, bathroom plumbing, and flooring are completed ahead of thorough site cleaning and final building control sign-off.

Do I need planning permission in Selston? (Ashfield District Council)

Navigating the planning process in Selston requires engaging with Ashfield District Council. While certain modest double storey rear extensions can be constructed under national Permitted Development rights, the conditions are exacting. Under Permitted Development, a two-storey rear addition must not extend more than three metres beyond the rear wall of the original dwelling, must sit at least seven metres from the rear boundary, and must match the roof pitch and exterior materials of the host building. Furthermore, upper-floor side-facing windows must be fitted with obscure glazing and non-opening mechanisms up to 1.7 metres from the internal floor level. If your project exceeds these dimensions, involves a side wraparound, or if your property is subject to an Article 4 Direction or conservation constraints, a full householder planning application is required. We take complete ownership of the planning journey: producing accurate existing and proposed architectural drawings, submitting the application via Ashfield's planning portal, monitoring progress through the standard eight-week statutory consultation period, and liaising directly with planning officers to secure a positive outcome.

Building regulations, inspections and paperwork

Every double storey extension constructed in Selston must adhere strictly to current Building Regulations to guarantee structural safety, fire separation, thermal efficiency, acoustic insulation, and adequate drainage. For domestic projects in Selston, building control services are administered by Erewash Borough Council through the joint Erewash and West Nottinghamshire building consultancy. This partnership oversees statutory inspections from start to finish. Our team submits the initial building notice or full plans application, complete with detailed construction drawings and structural engineering calculations. On site, our site manager coordinates mandatory inspection visits at critical project milestones: foundation trench excavation before concrete pours, damp proof course installation, first-floor structural timber and steel placement, roof construction, thermal insulation checks, and drainage pressure testing. Once our trades finish the internal fit-out and all electrical (Part P) and heating (Gas Safe) testing is certified, the building control officer conducts a final walk-through. They then issue a formal Completion Certificate. This document proves that your double storey extension is legally compliant, safe, and ready for future property transactions.

How we work, stage by stage

Our design and build service is structured to give Selston homeowners a transparent, stress-free experience from the initial conversation through to final sign-off. We begin with a thorough on-site feasibility consultation, assessing your plot, boundary lines, existing load-bearing walls, and drainage routes. Our architectural designers then develop layout plans that maximise upstairs and downstairs space while aligning with local planning guidelines. Next, we manage the planning submission with Ashfield District Council or confirm Permitted Development parameters, alongside coordinating structural engineering calculations. Before breaking ground, you receive a detailed, fixed-scope schedule of works with phased payment stages tied to physical milestones. During construction, our dedicated site manager oversees daily operations, coordinating bricklayers, carpenters, roofers, plumbers, and electricians while scheduling all building control inspections. We keep you updated throughout each phase, maintain a clean and secure site, and resolve any unexpected structural issues without delay. Once the build is fully finished, decorated, and certified by building control, we carry out a comprehensive handover inspection with you.

1. Step 1

   Initial Site Feasibility Survey

   We visit your Selston property to assess site levels, drainage runs, boundary lines, and structural layout before discussing your spatial goals and establishing an indicative budget.

2. Step 2

   Architectural Design & Calculations

   Our design team produces architectural drawings and elevations, while our structural engineer prepares calculations for foundations, lintels, and steel beam knock-throughs.

3. Step 3

   Planning & Building Regulations Submission

   We submit and manage your full householder planning application with Ashfield District Council or confirm statutory compliance under Permitted Development rules.

4. Step 4

   Groundwork & Substructure

   Our groundwork team excavates footings, routes drainage, pours concrete foundations, and lays the insulated sub-floor slab ready for building control inspection.

5. Step 5

   Superstructure, Steels & Roof

   Bricklayers build cavity walls with matching facing bricks, hoist structural steelwork, fit upper-floor joists, and construct the pitched roof structure to achieve weathertightness.

6. Step 6

   First Fix & Structural Openings

   We complete first-fix electrical and plumbing runs, insert structural lintels for knock-throughs, install high-density insulation, and apply hardwall plaster across both floors.

7. Step 7

   Second Fix & Completion Sign-Off

   Carpenters, electricians, and plumbers complete second-fix installations, fit sanitaryware and heating connections, and coordinate final building control sign-off for your Completion Certificate.

What drives the cost in Selston

The cost of a double storey extension in Selston is dictated by several practical site and structural variables. Substructure requirements often represent the first major variable; depending on historic ground conditions and soil composition in this part of Nottinghamshire, standard trench foundations may need deepening or upgrading to an engineered design. The structural complexity of opening up existing external walls on both the ground and first floor also drives cost, as wider open-plan kitchen and dining spaces require substantial steel beams and calculated padstones. Further price drivers include roof complexity, specifically whether we are tying a new pitched roof into existing valley systems, gables, or hip ends. Upstairs layout changes—such as integrating master en-suites, dressing rooms, or family bathrooms—require dedicated soil vent pipe routes, hot water cylinder upgrades, or new central heating loops. Finally, the choice of external finishes, such as sourcing bricks that accurately match older Nottinghamshire red-clay profiles, alongside specification choices for high-performance glazing, rooflights, and internal fittings, will determine where your project falls within our indicative range.

Projects we take on in Selston

In Selston, our double storey extension projects cater to diverse family requirements and property styles. Common configurations include two-storey rear additions that combine an open-plan kitchen, dining, and garden living room on the ground floor with an expansive master bedroom suite and en-suite bathroom above. For homeowners on corner plots or with wide side driveways, two-storey side extensions are popular, offering utility rooms, integrated garage conversions, or home offices downstairs, complemented by additional children's bedrooms or guest suites upstairs. We also design and build complex wraparound extensions that join side and rear footprints for transformative whole-house expansions. Whether modifying a traditional 1950s semi-detached home or extending a modern detached property, our builds are designed to enhance day-to-day functionality and add lasting property value.

Living in the house while we work

Many homeowners in Selston choose to live in their property while we construct their two-storey extension. Because a double storey build proceeds externally during the initial groundwork, brickwork, and roofing stages, your daily home life remains largely unaffected for the first several weeks. Daily living is most impacted when we knock through from the existing house into the new space on both floors. To manage this, we construct timber-framed, dust-sealed temporary partition walls that isolate living quarters from the work zone. We schedule structural openings, lintel insertions, and major plumbing or electrical switchovers systematically to keep your heating, power, and water running with minimal interruptions. Logistics are handled carefully on site: Selston properties often allow for vehicle parking and skip placement on private driveways, but where space is tighter, we arrange road permits or immediate grab-lorry removals. We establish clear working hours, keep common access paths safe and swept, and maintain open communication with your neighbours throughout the build.
