A well-designed single storey extension is the simplest way to create an open-plan kitchen, a bright family room or a larger ground-floor bedroom without the cost of moving home. As an experienced extension builder in Lincolnshire we handle every stage: initial concept, drawings, permissions, construction and sign-off.
Fixed quotes with staged payments and no hidden extras.
We prepare drawings and deal with local planners.
Typical single storey projects complete in eight to twelve weeks.
One schedule, one team, consistent quality on every task.
Single Storey Extension Choices
We design & build a wide variety of single storey home extensions across Lincolnshire:
Rear kitchen-diner up to 4 m deep, rooflights for natural light and bi-fold doors to the garden.
Combines rear and side zones for an L-shaped open-plan living area with corner glazing
modern look with hidden gutters, lantern rooflights and zinc or GRP finish.
Uses unused driveway width to add utility, pantry or study without losing garden space.
Extends a single-level property while maintaining ridge height and matching roof pitch.
Removes rear walls, inserts steel beams and links kitchen, dining and lounge into one space.
Initial Meeting & Survey
we measure your house, discuss goals, sketch ideas and outline a rough budget.
Concept & Fixed Quote
detailed drawings are prepared, specification agreed and a fixed-price contract issued.
Most rear additions within 4 m (detached) or 3 m (others) depth fall under Permitted Development. Anything larger, or any build on a designated site, needs householder permission. We prepare the site plan, scaled elevations and Design & Access Statement, then submit through the Planning Portal. Typical approval time is eight weeks.

Ready to discuss your application?
Under Class A rules you may extend up to 4 m (detached) or 3 m (others) without full permission. Deeper rear projects (up to 8 m or 6 m) require a Prior Approval process that notifies neighbours and the council. We prepare drawings, lodge the application and manage any queries.
Unsure if you qualify for PD?
All extensions need approval for foundations, insulation, structural openings, ventilation and drainage. Our engineers design steel beams for open-plan knock-throughs and submit drawings to Lincolnshire Building Control. Site inspections are booked at foundation, damp-proof course and completion stages.

Listed homes or those in Conservation Areas require Listed Building Consent before work starts. We create a heritage impact statement, source matching materials and liaise with Historic England to protect original features while adding modern space.

We start every design by modelling daylight angles from the south and west, then position roof-lights, lanterns or clerestory windows to keep both the new and existing rooms bright. Where overshadowing might occur we adjust eaves height or specify slim-frame bifolds to maximise glass area. On semi-detached plots we also check your neighbour’s windows, ensuring the extension roof slopes away to avoid blocking their light.
Allow four to six weeks for drawings, planning and structural calculations, then eight to twelve weeks on site. Foundations and drainage are normally finished in the first fortnight, followed by walls and roof to get the shell weather-tight. First-fix electrics and plumbing occupy weeks five to seven, after which plastering, second-fix joinery and kitchen fitting complete the schedule. A final fortnight is reserved for decoration, snag resolution and Building Control sign-off.
If your rear addition stays within Permitted Development limits - 4 m projection on a detached house or 3 m on others and the roof height remains below 4 m, you can build without full permission. Deeper projects up to 8 m (detached) or 6 m (others) use the Prior Approval route, which involves neighbour consultation but is faster than a householder application. Conservation areas or listed homes always need formal consent, regardless of size.
Yes. We isolate the work zone with temporary stud walls and dust sheets, keep services live, and schedule noisy demolition during daytime hours. Kitchen relocations can be staged so you always have running water and basic cooking facilities. Our site manager holds weekly walk-throughs to update you and adjust sequencing around family routines.
Pitched tiled roofs match existing architecture and allow vaulted ceilings with feature trusses. Flat GRP roofs give a crisp contemporary look and accept lanterns or flush skylights for extra daylight. Warm-roof build-ups exceed current insulation targets, and internal plastered soffits can hide LED downlights. We discuss maintenance, lifespan and cost before locking in the final specification.
If new foundations sit within three metres of a neighbour’s wall, or steel beams will be inserted into a shared masonry party-wall, the Party Wall etc. Act 1996 applies. We serve the notices, arrange a schedule of condition with an independent surveyor and programme steel installation only after awards are in place, preventing disputes and keeping the build on schedule.

Coverage Areas
We've been building Single Storey Extensions in Lincolnshire for over 2 generations, some of these towns include:
In Horncastle’s conservation area, side extensions must reflect the town’s handmade red brick and Welsh slate palette. We source reclaimed bricks, match soldier-course lintels and use timber sliding-sash windows to satisfy East Lindsey planners while delivering modern insulated envelopes.
Extending in Lincoln often involves Victorian terraces and steep streets near the cathedral. We design modest rear kitchens that respect the city’s heritage red brick while introducing slim aluminium sliders for garden access. The City of Lincoln Council prefers traditional roof pitches on visible elevations, so we tuck flat-roof elements below the eaves line and add conservation-style roof-lights to maintain skyline views.
Stamford’s limestone cottages and Georgian squares call for extensions in Clipsham stone with lime-pointed joints. Conservation officers expect Collyweston or appropriate replica slate on pitched roofs, and sash proportions on new openings. Inside, clients favour removing internal walls to create contemporary kitchen-diners that still read naturally from the street.
Proximity to tidal flood zones on the River Haven means raised finished floor levels and block-and-beam slabs are common. Boston Borough Council requests flood-resilient materials, insulated cavity boards and porcelain floor tiles, so homes can dry quickly if water ingress occurs. Lantern roofs and high-level clerestories bring extra light into deeper plan layouts.
Grimsby’s coastal climate brings salt-laden winds, so we specify fibreglass or single-ply flat roofs, marine-grade hinges on bifolds and corrosion-resistant fixings. Garden-facing extensions often include sheltered barbecue terraces to capture evening sun while shielding occupants from prevailing north-easterlies blowing across the Humber.
The town’s legacy of clay extraction leaves variable sub-soils. We commission soil investigations and, where required, install mini-piles capped with reinforced concrete beams to mitigate movement. External finishes usually mirror the buff bricks and dark-grey roof tiles found in post-war estates, keeping planners on side
Victorian properties overlooking the River Trent benefit from lean-to kitchen additions that frame water views through full-height glazing. Flood-risk assessments may dictate slot drains and permeable paving; we integrate these at design stage and liaise with West Lindsey Building Control for approval.
Newer estates off Boston Road favour rear kitchen-diners with gable-end glazing and roof lanterns. North Kesteven District Council typically turns applications around in eight weeks if ridge heights match the original dwelling and materials blend seamlessly with existing buff brickwork.
Properties on large plots near the Lincolnshire Wolds lend themselves to wrap-around or L-shaped extensions that capture panoramic countryside views. Cedar-clad garden rooms paired with aluminium corner sliders create an indoor-outdoor feel yet stay low maintenance for rural living.
Georgian terraces in Louth often require discreet rear additions hidden from Eastgate’s public realm. Flat-roof warm decks with parapet walls keep the extension below first-floor sill height, while heritage-approved roof-lights funnel daylight into deep kitchen zones without altering the historic façade.
