Full-plans building regulations drawings for The Avenues — the technical construction set covering structure, fire safety, insulation and Part L, drawn to satisfy building control so your builder can price and build with certainty, delivered in days and revised free until sign-off, with a free project check first.
Hull City Council granted 91% of the householder planning decisions it made in its latest published year — 4 points above the 87% England-wide householder average. Almost the whole district lies within a high tidal-flood-risk zone, so extensions and conversions are expected to raise finished floor levels and add flood resilience, which is where a policy-literate drawing pack earns its keep. Its dominant Victorian (1837–1901) and Edwardian (1901–1910) housing stock sets the design brief on most streets.
The permitted-development ceilings are fixed: 40m³ of new roof volume for a terraced loft and 50m³ for a semi or detached house under Class B, plus a 3m single-storey rear extension on a terrace or 4m on a detached house under Class A. The Avenues carries at least one Article 4 direction, and conservation areas including Avenues and Pearson Park, Princes Avenue and Newland remove those rights outright, so we confirm your exact address before a line is drawn. A validated householder application in The Avenues is determined against an 8-week statutory target.
Park Avenue (grandest of the four avenues, wide villas around the restored fountains), Westbourne Avenue (long avenue of gabled Victorian houses inside the conservation area), Marlborough Avenue (red-brick terraces and villas with heavy heritage control), Victoria Avenue (smaller avenue houses close to Princes Avenue), Princes Avenue (commercial and residential frontages in their own conservation area) and Salisbury Street (tight Victorian terraces on the eastern edge of the Avenues) — these are the The Avenues pockets our drawings cover most. Heritage designations here include Avenues and Pearson Park, Princes Avenue and Newland. Hull City Council weighs each proposal against the Hull Local Plan 2016–2032, where the HMO Article 4 direction means sub-division and student conversions are managed tightly against clustering and amenity standards. Many of the large villas have been split into flats and HMOs, and those units carry no householder permitted-development rights.. On roofs the borough is pitched slate roofs with decorative gables on the villas and double-pitched roofs on the terraces, over large late-Victorian villas and terraces off the four tree-lined avenues, Edwardian red-brick terraces and sub-divided houses in multiple occupation.
Planning permission decides whether you can build; the Building Regulations decide that what you build is safe, warm and sound. They are two separate approvals, run by different bodies, and a The Avenues project usually needs both. The building regulations set is the technical layer beneath the planning drawings — construction sections, structural details, insulation build-ups and fire-safety provisions that a builder works from and a building control surveyor checks against the approved documents.
In practice that means Part A structure — beam and foundation details with the structural calculations behind them; Part B fire — escape, protected routes and, in a loft, a fire door and mains-linked alarms; Part L conservation of fuel and power — U-values, insulation and airtightness; plus drainage, ventilation and stairs. On The Avenues's stock, which runs to large late-Victorian villas and terraces off the four tree-lined avenues, Edwardian red-brick terraces and sub-divided houses in multiple occupation, the recurring challenge is meeting Part L in solid-walled period houses without ruining the room, and we detail the insulation to hit the numbers with the least intrusion.
Building control applies everywhere in The Avenues regardless of planning designation, but in conservation areas such as Avenues and Pearson Park, Princes Avenue and Newland the two processes interact — insulation and window details often have to satisfy Part L and a planning condition at once. The Avenues sit inside Hull's houses-in-multiple-occupation Article 4 direction, so converting a family house to a small HMO here needs a full planning application rather than relying on permitted-development rights, and the council refuses new HMOs that would cluster three-in-a-row. We draw the construction details to reconcile both.
A full-plans set for The Avenues building control is checked against the Approved Documents. A typical extension or loft set covers each of these:
We produce the full-plans construction set — structure, fire, thermal and drainage details with the structural calculations — and submit it to your chosen building control body, whether that is Hull City Council's own team or an approved inspector, so problems are settled on paper before they cost money on site.
Building control is a separate approval, but most The Avenues projects clear planning first, so Hull City Council's live decision record below sets the context. Hull grants around 91% of the planning applications it decides, but in the Avenues the combined conservation-area and HMO Article 4 controls are the biggest factor shaping what design and use will pass. We handle both stages, so the construction drawings follow through seamlessly once permission is granted.

There are two ways to get building control approval, and for anything structural in The Avenues we recommend the full-plans route — particularly on the borough's large late-victorian villas and terraces off the four tree-lined avenues and edwardian red-brick terraces, where opening up an old structure tends to reveal surprises. A building notice lets work start with no approved drawings — cheaper up front, but the surveyor rules on compliance as the build proceeds, so a wrong detail is discovered mid-work and rebuilt at your cost. Full plans get the whole set checked and approved before a brick moves, which is what banks, warranty providers and future buyers want to see.
Full plans also protect the project commercially. With approved construction drawings your builder prices exact quantities rather than guessing, and there is a completion certificate at the end — the document a solicitor asks for when you sell across Park Avenue, Westbourne Avenue and Marlborough Avenue and the rest of The Avenues. Where a project sits in a controlled setting — almost the whole district lies within a high tidal-flood-risk zone, so extensions and conversions are expected to raise finished floor levels and add flood resilience — the construction details also have to respect what planning has conditioned, and we draw the full set and manage the building control submission to reconcile both.
Every structural project needs building regulations drawings whatever the planning position. A few of the The Avenues neighbourhoods and property types where we prepare them most often:
Building regulations drawings for Park Avenue's grandest of the four avenues, wide villas around the restored fountains — structure, fire and Part L detailed for building control sign-off.
Building regulations drawings for Westbourne Avenue's long avenue of gabled Victorian houses inside the conservation area — structure, fire and Part L detailed for building control sign-off.
Building regulations drawings for Marlborough Avenue's red-brick terraces and villas with heavy heritage control — structure, fire and Part L detailed for building control sign-off.
Building regulations drawings for Victoria Avenue's smaller avenue houses close to Princes Avenue — structure, fire and Part L detailed for building control sign-off.
Building regulations drawings for Princes Avenue's commercial and residential frontages in their own conservation area — structure, fire and Part L detailed for building control sign-off.
Building regulations drawings for Salisbury Street's tight Victorian terraces on the eastern edge of the Avenues — structure, fire and Part L detailed for building control sign-off.
They are different approvals and most projects need both. This is how they split in The Avenues.
| Planning permission | Building regulations | |
|---|---|---|
| Question it answers | Should this be built here? | Is it built safely and efficiently? |
| Decided by | Hull City Council planning | Building control body or approved inspector |
| Main drawings | Location, block, proposed plans & elevations | Structural, fire, thermal & construction details |
| Needed for permitted development? | No — a certificate is optional | Yes — always, before work starts |
In conservation areas such as Avenues and Pearson Park and Princes Avenue, a planning condition can dictate materials that the building regulations details must then also satisfy.
A fixed process built around how The Avenues projects are approved and inspected — most construction sets are ready within seven days of survey.
Send us your The Avenues postcode and scheme. We confirm whether you also need planning, which parts of the regulations apply, and whether Hull City Council building control or an approved inspector suits the job.
We measure the existing structure so the construction details, spans and junctions are drawn to the real building rather than an assumption — the base sound structural calculations depend on.
Chartered designers and engineers produce the full-plans set — structure, fire, Part L thermal, drainage and details — with the structural calculations that support every beam and foundation.
We submit the full-plans application to your building control body, resolve any queries before work starts, and revise the drawings free until the set is approved and the work signed off.
They are two separate approvals. Planning permission, decided by Hull City Council, answers whether a scheme should be built at all — its size, look and impact on neighbours. Building regulations, checked by a building control body, answer whether it is built safely and efficiently — structure, fire, insulation and drainage. A The Avenues project usually needs both, and even permitted-development work that skips planning still needs building control sign-off.
Yes — planning permission is not building control approval. The planning drawings show what the building looks like; building regulations drawings show how it is constructed, and no structural work in The Avenues can lawfully complete without a building control sign-off. The two sets are drawn together but approved by different bodies, so having one never removes the need for the other. Hull City Council is the decision-maker.
For anything structural in The Avenues — a loft, an extension or removing a wall — we recommend full plans. The whole construction set is checked and approved before work starts, so a non-compliant detail is caught on paper rather than rebuilt on site. On the borough's large late-victorian villas and terraces off the four tree-lined avenues that certainty matters, and a building notice — which lets a surveyor judge compliance as work proceeds — risks costly rework. Banks and warranty providers also prefer the approved full-plans set that Hull City Council or an approved inspector signs off.
Yes. You can use Hull City Council's building control team or an independent approved inspector — both enforce the same regulations, so it comes down to price, availability and continuity. We draw the full-plans set to the same standard either way and submit it to whichever body you choose, then manage the queries and inspections through to the completion certificate. This applies to your The Avenues address specifically.
Solid-walled period houses — common across The Avenues, including conservation areas such as Avenues and Pearson Park and Princes Avenue — are the hardest to bring up to Part L without losing room or altering the fabric. We detail the insulation to hit the required U-values with the least intrusion, using internal or roof-level build-ups and, where a planning condition protects the exterior, methods that satisfy both the energy standard and the heritage requirement at once. Hull City Council is the decision-maker.
We price each The Avenues job individually, because the structural content and the size of the construction set vary from a single beam to a whole-house refurbishment, and send a fixed, no-obligation quote within one working day. It covers the full-plans drawings and structural calculations with free revisions until sign-off. The building control body's own fee is separate. Call 020 7864 7245 to start.
